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}"
                        <af:column sortable="false" headerText="Name" id="c1" width="150">
                            <af:outputText value="#{}" id="ot1"/>
                        <af:column sortable="false" headerText="Mobile Number" id="c2">
                            <af:outputText value="#{row.mobNo}" id="ot2"/>
                        <af:column sortable="false" headerText="Salary" id="c3" align="right">
                            <af:outputText value="#{row.salary}" id="ot3"/>

  • 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:button text="Add Record" id="b1" actionListener="#{viewScope.ProgTableBean.addNewRcord}"/>

    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(),

  • now run and check application-

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();
            this.createViewObjectFromQueryStmt("dynamic1", query);

  • 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());
        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"/>

    Change this entry like this-

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

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

ADF Faces dvt:thematicMap to mark location using latitude and longitude

Hello all,
this post is about simple use of dvt:thematicMap component , this map is used for displaying some information of a particular geographic location such as population ,any trends or patterns
Map is called thematic because it doesn't include geographic details of location as rivers, ocean etc.
If you want to use geographic features then use <dvt:map>

Thematic map includes different basemap as world map and all continents map
for details see oracle docs - <dvt:thematicmap>
In this post i am just spotting locations using their latitude and longitude co-ordinates

  • So first step is create a fusion web application and drop a thematic map (world map) on page

  • then i have created a bean class to populate data in thematic map , this bean class contains properties (varaibles) for thematic map like Country Name,latitude and longitude

  • public class LocationDetail {
        private String location; // Name of Location
        private String countryNm; // Name of Country
        private String textDisp; // Additional Information to display
        private float lattitude; // Latitude of location
        private float longitude; // Longitude of Location
        public LocationDetail() {
        public void setLocation(String location) {
            this.location = location;
        public String getLocation() {
            return location;
        public void setCountryNm(String countryNm) {
            this.countryNm = countryNm;
        public String getCountryNm() {
            return countryNm;
        public void setTextDisp(String textDisp) {
            this.textDisp = textDisp;
        public String getTextDisp() {
            return textDisp;
        public void setLattitude(float lattitude) {
            this.lattitude = lattitude;
        public float getLattitude() {
            return lattitude;
        public void setLongitude(float longitude) {
            this.longitude = longitude;
        public float getLongitude() {
            return longitude;

  • created a managed bean and a List data structure to add location detail and added this List reference to thematic map component

  • <dvt:thematicMap basemap="world" id="tm1" summary="World Map" styleClass="AFStretchWidth"
                                         partialTriggers="::b1" inlineStyle="background-color:#e9ffdc;">
                            <dvt:areaLayer layer="continents" id="al2">
                                <dvt:pointDataLayer id="dl1" value="#{viewScope.MapBean.mapDetail}" var="row">
                                    <dvt:pointLocation id="pl1" type="pointXY" pointY="#{row.lattitude}"
                                        <dvt:marker id="m1" shortDesc="#{row.textDisp}"
                                                    fillColor="#ff0000" borderWidth="1.0" scaleX="2.0" scaleY="2.0"
                                                    labelDisplay="on" labelPosition="bottom" shape="triangleDown"
                                                    value="#{row.location}" labelStyle="color:maroon;font-size:10px;"/>

  • then i have added a form on page to add new location by user, this form has 5 fields (Country Name, Location, Latitude, Longitude and Description) and a button to add this information to list

  • <af:panelBox text="Add New Location" id="pb1" showDisclosure="false">
                            <f:facet name="toolbar"/>
                            <af:panelFormLayout id="pfl1" rows="1" maxColumns="2">
                                <f:facet name="footer">
                                    <af:button text="Add Location" id="b1"
                                <af:inputText label="Country" id="it3"
                                <af:inputText label="Location" id="it4"
                                <af:inputText label="Latitude" id="it1" contentStyle="width:100px;color:red;"
                                <af:inputText label="Longitude" id="it2" contentStyle="width:100px;color:red;"
                                <af:inputText label="Description" id="it5" contentStyle='width:200px;color:darkgreen;'

  • now see the managed bean code to add this information to list and to populate default locations

  • public class MapBean {
        //List to contain Location Detail
        private List<LocationDetail> mapDetail = new ArrayList<LocationDetail>();
        // Bindings of page component to access value
        private RichInputText cntryNmBind;
        private RichInputText latitudeBind;
        private RichInputText longitudeBind;
        private RichInputText locationBind;
        private RichInputText descriptionBind;
        public MapBean() {
            // Add Default location to map
            LocationDetail location = new LocationDetail();
            location.setTextDisp("Economic Capital of India");
            location.setLongitude((float) 72.8258);
            location.setLattitude((float) 18.9750);
            location = new LocationDetail();
            location.setTextDisp("Industrial City in North India");
            location.setLongitude((float) 80.20);
            location.setLattitude((float) 26.28);
            System.out.println("List is-" + mapDetail);
        public void setMapDetail(List mapDetail) {
            this.mapDetail = mapDetail;
        public List getMapDetail() {
            return mapDetail;
        /**Method to add new Location
         * @param actionEvent
        public void addLocationButton(ActionEvent actionEvent) {
            if (cntryNmBind.getValue() != null && latitudeBind.getValue() != null && longitudeBind.getValue() != null &&
                locationBind.getValue() != null && descriptionBind.getValue() != null) {
                LocationDetail location = new LocationDetail();
                location = new LocationDetail();
                location.setLongitude(Float.parseFloat((String) longitudeBind.getValue()));
                location.setLattitude(Float.parseFloat((String) latitudeBind.getValue()));
        public void setCntryNmBind(RichInputText cntryNmBind) {
            this.cntryNmBind = cntryNmBind;
        public RichInputText getCntryNmBind() {
            return cntryNmBind;
        public void setLatitudeBind(RichInputText latitudeBind) {
            this.latitudeBind = latitudeBind;
        public RichInputText getLatitudeBind() {
            return latitudeBind;
        public void setLongitudeBind(RichInputText longitudeBind) {
            this.longitudeBind = longitudeBind;
        public RichInputText getLongitudeBind() {
            return longitudeBind;
        public void setLocationBind(RichInputText locationBind) {
            this.locationBind = locationBind;
        public RichInputText getLocationBind() {
            return locationBind;
        public void setDescriptionBind(RichInputText descriptionBind) {
            this.descriptionBind = descriptionBind;
        public RichInputText getDescriptionBind() {
            return descriptionBind;

  • you can see in thematicMap map source - how bean variables are used to point latitude, longitude etc
  • Run this application, you will see default location are marked at first time

  • now add any other location using 'Add New Location' form 

  • See this video how locations are added to thematic map using their latitude and longitude

and finally after adding all location , map looks like this
