Populate data in ADF Table using Web Service Data Control


My previous post was about creating a JAX-WS Web Service from Java Bean. Now In this post, I am going to elaborate about consuming that Web Service in ADF Application and show Employees data in ADF Table

So for this requirement, We need to use Web Service Data Control and from that WSDL we can create ADF Faces components

Let's see how to implement this

ADF Basics: Populate simple programmatic View Object using POJO


Hello All

I hope you all know that we have 4 type of viewObjects in ADF, Here we'll discuss about a simple programmatic viewObject
  • Entity Object Based
  • SQL Query Based
  • Static List Based
  • Programmatic ViewObject
Programmatic ViewObject can be created by overriding appropriate methods in ViewObject's Impl class to retireve data from REF CURSOR, Array or any Java file
Here in this post I am using an ArrayList (POJO based) to populate viewObject records so for that I'll override some methods of ViewObject Impl class

Working with af:iterator and af:forEach programmatically (Add and delete records using List)

In previous post Working with af:iterator and af:forEach programmatically (Populate values using POJO from Managed Bean) we saw that how can we populate record from a List to af:iterator and af:forEach (ADF Faces Component)

So this post is about adding and deleting of records from List while List is presented using af:iterator.
here i am extending previous post and using same sample application



Added two fields and button on page to add records 


<af:panelFormLayout id="pfl1" rows="1">
                    <af:inputText label="Name" id="it1" binding="#{viewScope.PopulateIteratorBean.nameBind}"/>
                    <af:inputText label="Department" id="it2" binding="#{viewScope.PopulateIteratorBean.deptNameBind}"/>
                    <af:button text="Add" id="b1"
                               actionListener="#{viewScope.PopulateIteratorBean.addNewRecordAction}"/>
                </af:panelFormLayout>




and on this button action simply added both attributes to List and added partial trigger of button to af:iterator to refresh it


    // Component binding to access inputValue from page
    
    private RichInputText nameBind;
    private RichInputText deptNameBind;
    
    public void setNameBind(RichInputText nameBind) {
        this.nameBind = nameBind;
    }

    public RichInputText getNameBind() {
        return nameBind;
    }

    public void setDeptNameBind(RichInputText deptNameBind) {
        this.deptNameBind = deptNameBind;
    }

    public RichInputText getDeptNameBind() {
        return deptNameBind;
    }

    /**Method to add record in List and show on page using af:iterator and af:forEach
     * @param actionEvent
     */
    public void addNewRecordAction(ActionEvent actionEvent) {
        if (nameBind.getValue() != null && deptNameBind.getValue() != null) {
            EmployeeDet obj = new EmployeeDet(nameBind.getValue().toString(), deptNameBind.getValue().toString());
            employeeDetail.add(obj);
            
        }
    }


On page - add a new record (record added in List and appeared in iterator as well)


So it is quite simple to add records but deletion of record is a bit tricky but not difficult at all :)
Let's see this-
For deleting record i have added a delete link inside iterator so that it should appear for each record as you can see in snap (above)
Here question is that how to know that which record should be deleted  ?

So for this i have added a f:attribute tag to link , this attribute contains the value of current item of iterator



f:attribute derives it's value from var of af:iterator/af:forEach, this var represents each item of List
Now on delete button's action - get the current item and remove it from List


    /**Method to delete selected record
     * @param actionEvent
     */
    public void deleteRecordAction(ActionEvent actionEvent) {
        //Get value from f:attribute (current item)
       Object itemVal= actionEvent.getComponent().getAttributes().get("itemVal");
       //Remove selected item from List
       employeeDetail.remove(itemVal);
    }

Working with af:iterator and af:forEach programmatically (Populate values using POJO from Managed Bean)


This is another post about Working programmatically with ADF (populating af:iterator and af:forEach programmatically )

Previously i have posted about populating af:iterator and af:forEach using ADF BC and binding layer to show master-detail relation
Implementing master/detail tree relation using af:Iterator and af:forEach for better UI designs - Oracle ADF

For this post i am populating employee name and it's department name using List datastructure ,to get and set value of attributes

Created a java bean class , it has 2 variable for both attributes




public class EmployeeDet {
    public EmployeeDet(String name, String deptName) {
        this.name = name;
        this.deptName = deptName;
    }
    //Attribute to display EmployeeName and Department Name
    private String name;
    private String deptName;

    public void setName(String name) {
        this.name = name;
    }

    public String getName() {
        return name;
    }

    public void setDeptName(String deptName) {
        this.deptName = deptName;
    }

    public String getDeptName() {
        return deptName;
    }
}

Next step is to create a managed bean to populate data in af:iterator and af:forEach , this managed bean makes use of
EmployeeDet 
java bean class to add data in same format for all items of iterator and forEach. A List data structure is used to pass all values to iterator. See code of managed bean 




    //Constructor-populate default records
    public PopulateIteratorBean() {

        EmployeeDet obj = new EmployeeDet("Ashish Awasthi", "Oracle ADF");
        employeeDetail.add(obj);
        obj = new EmployeeDet("Alex Smith", "Java");
        employeeDetail.add(obj);
        obj = new EmployeeDet("James S", "PHP");
        employeeDetail.add(obj);
    }
    //ArrayList to poplate data in af:iterator and af:forEach
    private List<EmployeeDet> employeeDetail = new ArrayList();

    public void setEmployeeDetail(List<EmployeeDet> employeeDetail) {
        this.employeeDetail = employeeDetail;
    }

    public List<EmployeeDet> getEmployeeDetail() {

        return employeeDetail;
    }

Now drop af:iterator on page and set it's properties like value, var etc


using var reference of iterator , set value in output text to show Employee Name and DepartmentName , see XML source of af:iterator


<af:panelGroupLayout id="pgl1" layout="horizontal">
                        <af:iterator id="i1" value="#{viewScope.PopulateIteratorBean.employeeDetail}" var="item">
                            <af:panelBox id="pb2" showDisclosure="false">
                                <f:facet name="toolbar"/>
                                <af:panelGroupLayout id="pgl3" layout="horizontal">
                                    <af:outputText value="#{item.name}" id="ot1"
                                                   inlineStyle="font-weight:bold; font-size:medium; color:#0572ce;;"/>
                                    <af:spacer width="2" height="0" id="s1"/>
                                    <af:outputText value="(#{item.deptName})" id="ot2"
                                                   inlineStyle="font-weight:bold;font-size:small;color:red;"/>
                                </af:panelGroupLayout>
                            </af:panelBox>
                        </af:iterator>
                    </af:panelGroupLayout>  

on running it looks like this-


do same for af:forEach


<af:panelGroupLayout id="pgl2" layout="horizontal">
                        <af:forEach items="#{viewScope.PopulateIteratorBean.employeeDetail}" var="feach">
                            <af:showDetailHeader text="#{feach.deptName}" disclosed="true" id="sdh1">
                                <af:outputText value="#{feach.name}" id="ot3"
                                               inlineStyle="font-weight:bold; font-size:medium; color:#0572ce;;"/>
                            </af:showDetailHeader>
                        </af:forEach>

Programmatically populate values in ADF Faces multiSelect component (af:selectManyCheckbox, af:selectManyChoice, af:selectManyListbox, af:selectManyShuttle)

ADF Faces provides some component to support multiple selection as af:selectManyListbox, af:selectManyCheckbox, af:selectManyChoice, af:selectManyShuttle
In this post we will see how to populate values in these component from managed bean using POJO
You can read my previous post on multiple selection that was about populating multiselect component using ADF BC and binding layer
Using Multiple Selection (selectManyListbox & selectManyCheckbox component) in ADF
Shuttle Component in Oracle ADF (Allow Multiple Selection)

See the step by step implementation-



  • Create a Fusion Web Application and a managed bean in viewController


  • Create a variable of type java.util.List in managed bean, and generate its accessors

  •     //List to show records in selectMany components
        List<SelectItem> allValuesList;
    
        public void setAllValuesList(List<SelectItem> allValuesList) {
            this.allValuesList = allValuesList;
        }
    
        public List<SelectItem> getAllValuesList() {
            return allValuesList;
        }
    

  • This list contains value of type javax.faces.model.SelectItem; that is supported by af:selectManyCheckbox, af:selectManyChoice, af:selectManyListbox compoent

  •     //List to show records in selectMany components
        List<SelectItem> allValuesList;
    
        public void setAllValuesList(List<SelectItem> allValuesList) {
            this.allValuesList = allValuesList;
        }
    
        public List<SelectItem> getAllValuesList() {
            if (allValuesList == null) {
                allValuesList = new ArrayList<SelectItem>();
                allValuesList.add(new SelectItem(1, "India"));
                allValuesList.add(new SelectItem(2, "Australia"));
                allValuesList.add(new SelectItem(3, "America"));
                allValuesList.add(new SelectItem(4, "United Kingdom"));
            }
            return allValuesList;
        }
    

  • See how to add this list reference to  af:selectManyCheckbox component, just drag n drop component on page


  • Set managed bean list reference to selectManyCheckbox component, records stored in this list will be populated in component


  • Suppose I have to show some record as selected by default on page load so for this requirement created another List in managed bean and added it to value property of selectManyCheckbox component
    Value property of component refers only selected records but selectItems component refers all records of component

  •     //List to show selected values in selectMany Component
        List selectedValues;
    
        public void setSelectedValues(List selectedValues) {
            this.selectedValues = selectedValues;
        }
    
        public List getSelectedValues() {
            if (selectedValues == null) {
                selectedValues = new ArrayList();
                selectedValues.add(1);
                selectedValues.add(3);
                System.out.println("List is-" + selectedValues);
            }
            return selectedValues;
        }
    

    See af:selectManyCheckbox source -

    <af:selectManyCheckbox id="smc1" value="#{viewScope.ProgSelectManyComp.selectedValues}">
                                        <f:selectItems value="#{viewScope.ProgSelectManyComp.allValuesList}" id="si1"/>
                                    </af:selectManyCheckbox>
    

  • Now run this application and see component on page


  • Following same steps i have three more component on page , all 3 adf faces component support multiple selection
    af:selectManyChoice-

    <af:selectManyChoice label="Label 1" id="smc2"
                                                         value="#{viewScope.ProgSelectManyComp.selectedValues}"
                                                         simple="true">
                                        <f:selectItems value="#{viewScope.ProgSelectManyComp.allValuesList}" id="si2"/>
                                    </af:selectManyChoice>
    


    af:selectManyListbox-

    <af:selectManyListbox label="Label 1" id="sml1"
                                                          value="#{viewScope.ProgSelectManyComp.selectedValues}"
                                                          simple="true">

                                    </af:selectManyListbox>
    


    af:selectManyShuttle-

     <af:selectManyShuttle label="Label 1" id="sos1" simple="true"
                                                           value="#{viewScope.ProgSelectManyComp.selectedValues}"
                                                           contentStyle="width:50px;">

Populate af:table programmatically from managead bean using POJO

This post is about a common question
How can we populate an af:table programmatically ?

It means that data in af:table is not populated through model layer (Using ViewObject) using binding layer. lets say I have some values in our managed bean and have to show records in tabular format on page

So what we have to do -
  • First you should know the number and data type of columns in table, suppose i have to populate a table for person details (name, mobile number and salary). to get and set value of columns i have created a java bean class , it has 3 variable for 3 columns



  • // Java Class to set and get value for table column
    public class PersonBean {
    
        public PersonBean(String name, String moNo, Integer salary) {
            this.Name = name;
            this.mobNo = moNo;
            this.salary = salary;
        }
        private String Name;
        private String mobNo;
        private Integer salary;
    
        public void setName(String Name) {
            this.Name = Name;
        }
    
        public String getName() {
            return Name;
        }
    
        public void setMobNo(String mobNo) {
            this.mobNo = mobNo;
        }
    
        public String getMobNo() {
            return mobNo;
        }
    
        public void setSalary(Integer salary) {
            this.salary = salary;
        }
    
        public Integer getSalary() {
            return salary;
        }
    }
    

  • Next step is to create a managed bean for referencing af:table , this managed bean makes use of person java bean class to add data in same format for all table rows. A List data structure is used to pass all values in af:table. See code of managed bean 

  • //ArrayList to poplate data in af:table
        List<PersonBean> personList = new ArrayList();
    
        //To Populate default row in table (Code in Constructor)
    
        public ProgTableBean() {
            personList.add(new PersonBean("Ashish Awasthi", "xxxxxxxxxx", 50000));
        }
    
        public void setPersonList(List<PersonBean> personList) {
            this.personList = personList;
        }
    
        public List<PersonBean> getPersonList() {
            return personList;
        }
    

  • Now just drop an af:table on page and set it's properties like value, column header and text values in columns

  •  As i have to show only 3 columns so deleted extra ones

     Set properties -
     value- from where table collection is populated
     columns values- take the var reference of table and refer variable name in List (here 'row' is table var and second is variable name in person bean class)


     See the XML source of af:table-

    <af:table var="row" rowBandingInterval="1" id="t1" value="#{viewScope.ProgTableBean.personList}"
                              partialTriggers="::b1">
                        <af:column sortable="false" headerText="Name" id="c1" width="150">
                            <af:outputText value="#{row.name}" id="ot1"/>
                        </af:column>
                        <af:column sortable="false" headerText="Mobile Number" id="c2">
                            <af:outputText value="#{row.mobNo}" id="ot2"/>
                        </af:column>
                        <af:column sortable="false" headerText="Salary" id="c3" align="right">
                            <af:outputText value="#{row.salary}" id="ot3"/>
                        </af:column>
                    </af:table>
    

  • Now run this application and see there will be one row in table as code is added in constructor of managed to populate one row


  • I have added a form and button in page to add new records in table , see the form source code

  • <af:panelFormLayout id="pfl1">
                        <f:facet name="footer"/>
                        <af:inputText label="Name :" id="it1" binding="#{viewScope.ProgTableBean.nameBind}"/>
                        <af:inputText label="Mobile Number :" id="it2" binding="#{viewScope.ProgTableBean.mobNumBind}"/>
                        <af:inputText label="Salary :" id="it3" binding="#{viewScope.ProgTableBean.salaryBind}">
                            <af:convertNumber/>
                        </af:inputText>
                        <af:button text="Add Record" id="b1" actionListener="#{viewScope.ProgTableBean.addNewRcord}"/>
                    </af:panelFormLayout> 
     

    Code in managed bean for button action-

        /**Method to add new record in table
         * @param actionEvent
         */
        public void addNewRcord(ActionEvent actionEvent) {
            //Get all values using compoenet binding as mobNumBind
            if (mobNumBind.getValue() != null && nameBind.getValue() != null &&
                salaryBind.getValue() !=
                null) {
                // Add new Record in List
                personList.add(new PersonBean(nameBind.getValue().toString(), mobNumBind.getValue().toString(),
                                              Integer.parseInt(salaryBind.getValue().toString())));
            }
        }

Populate Dynamic table and form using af:dynamicComponent and dynamic viewObject - Oracle ADF

This post is about a common development requirement- Can we increase or decrease number of fields , type of fields (columns in case of table), data in fields at run time?

Suppose i have to show data of Departments and Employees table on page using only one af:table component. It means columns should be generated dynamically at run time depending on any defined condition
So for this requirement i am using dynamic viewObject in model layer and af:dynamicComponent in view layer
See previous post about creating dynamic viewObject-
Creating Dynamic View Object at Runtime programmatically - Oracle ADF

See step by step implementation-
  • Create Fusion Web Application and follow the link posted above to create dynamic viewObject, in short create a viewObject using dual and a method in AMImpl to create dynamic viewObject from sql query


  •     /**Method to create viewObject using SQL query
         * @param query
    
    
    
    
    
    
    
         */
        public void createNewViewObject(String query) {
            ViewObject dynVo = this.getdynamic1();
            dynVo.remove();
            this.createViewObjectFromQueryStmt("dynamic1", query);
            this.getdynamic1().executeQuery();
        }
    

  • Created a page and added an inputText to enter SQL query and a button to process that query and create dynamic viewObject at run time


  • See Managed Bean code to process query, value of inputText is passed using component binding

  •     private RichInputText sqlQueryBind;
    
        public DynamicTableBean() {
        }
    
        /*****Generic Method to call operation binding**/
        public BindingContainer getBindingsCont() {
            return BindingContext.getCurrent().getCurrentBindingsEntry();
        }
    
        /**
         * Generic Method to execute operation Binding
         * */
        public OperationBinding executeOperation(String operation) {
            OperationBinding createParam = getBindingsCont().getOperationBinding(operation);
            return createParam;
    
        }
    
        /**Method to create viewObject
         * @param actionEvent
         */
        public void createViewObjectAction(ActionEvent actionEvent) {
            if (sqlQueryBind.getValue() != null) {
                OperationBinding ob = executeOperation("createNewViewObject");
                ob.getParamsMap().put("query", sqlQueryBind.getValue().toString());
                ob.execute();
            }
        }
    
        public void setSqlQueryBind(RichInputText sqlQueryBind) {
            this.sqlQueryBind = sqlQueryBind;
        }
    
        public RichInputText getSqlQueryBind() {
            return sqlQueryBind;
        }
    

  • Now dropped this dual viewObject on page as dynamic form and dynamic table from Data Control (this snap is about creating form)



  • Next is to change pageDef entry for this dynamic component , open pageDef and goto treeBinding. there is an entry for nodeDefinition, there will be separate treeBinding for form and table both (you should change both)

  •  <tree IterBinding="dynamic1Iterator" id="dynamic1">
                <nodeDefinition DefName="dynamictableapp.model.view.dynamicVO" Name="dynamic10"/>
            </tree>
    

    Change this entry like this-

     <tree IterBinding="dynamic1Iterator" id="dynamic1">
                <nodeDefinition Name="dynamic10"/>
            </tree>
    

  • Now run this application and enter SQL query in box and press process button

Populate af:treeTable programatically using POJO in Oracle ADF (11g & 12c)

Hello All
This post is about creating & populating af:treeTable programmatically in ADF 11g and 12c
treeTable is basically a hierarchical representation of data, using ADF model layer we can create treeTable very easily by defining master-detail relation between viewObjects
see my previous posts on treeTable-
Tree Table Component in Oracle ADF(Hierarchical Representation)
Tree Table Component with declarative presentation in ADF, Access childs without custom selection listener
Expand and Collapse an af:treeTable programmatically in ADF Faces (Oracle ADF)
Refreshing Child Nodes of an af:treeTable / af:tree in Oracle ADF



to populate treeTable programmatically we need to configure data set that fits to tree hierarchy
thanks to Chris Muir's post about programmatic creation of treeTable
http://one-size-doesnt-fit-all.blogspot.in/2007/05/back-to-programming-programmatic-adf.html

there is 4-5 simple steps to do-
  • Create a fusion web application and drop a af:treeTable on page , in treeTable creation wizard select "bind later" 


  • now create managed bean to populate data in treeTable, create a simple List in managed bean of type POJO class (a java class that contains attributes and their accessor  )
  • so in this app i am going to Tv Serial and respective character names in treeTable, for that i have created a class that contains POJO for treeTable

  • import java.util.ArrayList;
    import java.util.List;
    
    
    public class Seasons {
        public Seasons(String name) {
            this.name = name; // To Store Header Values (Storing Seasons Name :))
            characters = new ArrayList<Seasons>(); // To Store Detail Values (Storing Season's Charatcers)
        }
    
        public void setCharacters(List<Seasons> empDet) {
            this.characters = empDet;
        }
    
        public List<Seasons> getCharacters() {
            return characters;
        }
        private String name;
        private List<Seasons> characters;
    
    
        public void setName(String name) {
            this.name = name;
        }
    
        public String getName() {
            return name;
        }
    // This methods directly add characters value in list
        public void addEmp(Seasons employee) {
            characters.add(employee);
        }
    
    }
    

  • In this class the characters list behaves as child of seasons, so in managed bean define a top-level list (that contains both master and detail) and add values

  • See managed Bean Code-
    import java.util.ArrayList;
    import java.util.List;
    
    import org.apache.myfaces.trinidad.model.ChildPropertyTreeModel;
    
    public class ProgrammaticTreeTabBean {
        List<Seasons> seasonList = new ArrayList<Seasons>();
    
        ChildPropertyTreeModel charatcerVal;
    
        public ProgrammaticTreeTabBean() {
            super();
            // Creating tree for Seasons and Characters details
            // Adding Master Values (seasons)
            Seasons season1 = new Seasons("Game of Thrones");
           // Adding Detail Values (Child Node-Characters)
            Seasons character = new Seasons("Tywin Lannister");
            season1.addCharaters(character);
            character = new Seasons("Tyrion Lannister");
            season1.addCharaters(character);
            character = new Seasons("Jaime Lannister");
            season1.addCharaters(character);
            character = new Seasons("Cersie Lannister");
            season1.addCharaters(character);
            character = new Seasons("Ned Stark");
            season1.addCharaters(character);
    
            // Adding Master Values (seasons)
            Seasons season2 = new Seasons("Arrow");
            // Adding Detail Values (Child Node-Characters)
            character = new Seasons("Oliver Queen");
            season2.addCharaters(character);
            character = new Seasons("Moira Queen");
            season2.addCharaters(character);
            character = new Seasons("Laurel Lance");
            season2.addCharaters(character);
            character = new Seasons("Sara Lance");
            season2.addCharaters(character);
    
            // Adding Master Values (seasons)
            Seasons season3 = new Seasons("Vikings");
          // Adding Detail Values (Child Node-Characters)
            character = new Seasons("Ragnar Lothrak");
            season3.addCharaters(character);
    
            // Adding all list to topList
            seasonList.add(season1);
            seasonList.add(season2);
            seasonList.add(season3);
            // Filtering Child Data, ChildPropertyTreeModel creates a TreeModel from a List of beans, see
            // https://myfaces.apache.org/trinidad/trinidad-api/apidocs/org/apache/myfaces/trinidad/model/ChildPropertyTreeModel.html
            charatcerVal = new ChildPropertyTreeModel(seasonList, "characters");
        }
    
        public ChildPropertyTreeModel getCharatcerVal() {
            return charatcerVal;
        }
    }
    

  • Now code part is complete, now configure your treeTable to show data, see XML source of af:treeTable

  • <af:treeTable rowBandingInterval="0" id="tt1"
                                  value="#{pageFlowScope.ProgrammaticTreeTabBean.charatcerVal}" var="node"
                                  rowSelection="single" initiallyExpanded="true">
                        <f:facet name="nodeStamp">
                            <af:column headerText="Node Stamp" id="c1" width="250">
                                <af:outputText value="#{node.name}" id="ot1" inlineStyle="font-weight:bold;"/>
                            </af:column>
                        </f:facet>
                    </af:treeTable>
    

  • Now run your application and check , what you have done ;)
