Create shortcut of page on a button click in Oracle ADF using JShortcut library (For windows)

This post is about a small trick to create shortcut file from ADF application
Actually this type of requirement doesn't come in picture when you are working in web application , for web application bookmarks replaces desktop shortcut
Still if you want to do this then you can follow approach mentioned in this post

Creating shortcut programmatically requires access of operating system but you need not to worry about that
There is a java library to do this for you - JShortcut
Download jar files from here..

1. Now first step is to create a fusion web application and add this jar to viewController project

2. Create a page (independent runnable like jspx or jsf not fragments) and drop a button in that
3. Create a managed bean to handle button's action
    Here we will make use of JShellLink class of this library

See what docs says about this -

Provide access to shortcuts (shell links) from Java. The native library (jshortcut.dll) is loaded when JShellLink is first loaded. By default, JShellLink first looks for the native library in the PATH, using System.loadLibrary. If the native library is not found in the PATH, JShellLink then looks through each directory in the CLASSPATH (as determined by the value of the system property java.class.path). If an entry in the CLASSPATH is a jar file, then JShellLink looks for the native library in the directory containing that jar file. The application can override this behavior and force JShellLink to look for the native library in a specific directory by setting the system property JSHORTCUT_HOME to point to that directory. This property must be set before the JShellLink class is loaded. This makes it possible to use this library from a self-extracting jar file. 



4. Get the url of current page
 How to get url of current page in ADF Application?
 (See button action listener code for this )
5. Check code written in managed bean-

import javax.faces.context.FacesContext;
import javax.faces.event.ActionEvent;

import javax.servlet.http.HttpServletRequest;

import net.jimmc.jshortcut.JShellLink;

import oracle.adf.controller.ControllerContext;

    JShellLink link;
    String filePath;

    /**Button action listener to create shortcurt of current page on desktop
     * @param actionEvent
     */
    public void createSortcutonDpAction(ActionEvent actionEvent) {
        try {
            //Get url of current ViewPort
            String viewId = ControllerContext.getInstance().getCurrentViewPort().getViewId();
            String viewUrl = ControllerContext.getInstance().getGlobalViewActivityURL(viewId);

            //Get Server Name and Port
            FacesContext fctx = FacesContext.getCurrentInstance();
            HttpServletRequest hsrequest = (HttpServletRequest) fctx.getExternalContext().getRequest();

            String serverName = hsrequest.getServerName();
            int serverPort = hsrequest.getServerPort();

            String runnableUrl = "http://" + serverName + ":" + serverPort + viewUrl;

            //Create Object of shortcurt link
            link = new JShellLink();
            filePath = JShellLink.getDirectory("") + runnableUrl;
            //Set Where you want to create shortcut
            link.setFolder(JShellLink.getDirectory("desktop"));
            //Set shortcut file name
            link.setName("Programmatically Created Shortcut");
            //Use ico file to use as shortcut icon
            link.setIconLocation("C://Users//Admin//Desktop//Jdev_Logo.ico");
            link.setPath(filePath);
            link.save();

        } catch (Exception ex) {
            ex.printStackTrace();
        }

    }

6.  All done :) , run and check application
Click on button and check on desktop

Same code can be used to create shortcut from pure java application
Cheers :) Happy Learning

Reading html source of a webpage (url) using Oracle ADF (af:richTextEditor) & Java

This post is about a common question asked in java-

How to read page source of a website ? or how to get html source of an url?

so for that there is a simple piece of code to read html source of a webpage using it's url, and i have added  af:richTextEditor (ADF Faces component for ricj text formatting) to show html form of url source

• I have a page with one input text to capture url entered by user, a button to fetch html source of that webpage and a af:richTextEditor to show source code in editing mode and in html mode 
  





• See how to get webpage source from an url using java and save it to a html file (download a webpage ), Bind inputText and richInputText to managed bean and craete a actionListener on button to get source



    // Input text Binding to get URL
    private RichInputText webPageUrlBind;
    // RickInput text Binding to set Source
    private RichTextEditor richTextBind;
    public void setWebPageUrlBind(RichInputText webPageUrlBind) {
        this.webPageUrlBind = webPageUrlBind;
    }

    public RichInputText getWebPageUrlBind() {
        return webPageUrlBind;
    }

    public void setRichTextBind(RichTextEditor richTextBind) {
        this.richTextBind = richTextBind;
    }

    public RichTextEditor getRichTextBind() {
        return richTextBind;
    }
    /**Method to get html source of url (webpage) and set this to rickTextEditor
     * @param actionEvent
     */
    public void getSourceCodeAction(ActionEvent actionEvent) {
        URL url = null;

        try {
            if (webPageUrlBind.getValue() != null) {
                // Define your URL- Get value from input text using binding
                url = new URL(webPageUrlBind.getValue().toString());
            }
            URLConnection conn = url.openConnection();

            // open the stream and put it into BufferedReader
            BufferedReader br = new BufferedReader(new InputStreamReader(conn.getInputStream()));

            String inputLine;
            String sourceCode = "";

            //Save html file (HTML Source Code of given URL)
            String fileName = "D:/web-content.html";
            File file = new File(fileName);

            if (!file.exists()) {
                file.createNewFile();
            }

            //use FileWriter to write file
            FileWriter fw = new FileWriter(file.getAbsoluteFile());
            BufferedWriter bw = new BufferedWriter(fw);
            System.out.println("Printing WebPage source on console, Please wait...\n");
            while ((inputLine = br.readLine()) != null) {
                System.out.println(inputLine);
                bw.write(inputLine);
                sourceCode = sourceCode.concat(inputLine);
            }

            bw.close();
            br.close();
            richTextBind.setValue(sourceCode);
            AdfFacesContext.getCurrentInstance().addPartialTarget(richTextBind);
            System.out.println("\n\nYour file is save in D drive! Congratulations ");

        } catch (MalformedURLException e) {
            e.printStackTrace();
        } catch (IOException e) {
            e.printStackTrace();
        }

    }






• now click on button and see , here i am getting source code of this blog http://oracleadf-java.blogspot.in/





• now switch RichTextMode to see html preview of this source, it is exactly looking like live webpage, it shows one can practice in this ADF Faces's rickTextEditor to learn html tags





• and see in D drive of your system a file named web-content created , it contains whole source of this webpage

 Cheers - Happy Learning :)
