How to call java function in javascript

Hello Everyone,
Can anyone tell me solution that:
How to call java function in javascript?
Thanks,
VIDs

You can't since Java is running on the server and javascript is running in the browser long after the Java side of things has finished executing. Assuming you're not talking about an applet here.
But you can make calls back to the server through Ajax. All you need is something like a servlet on the receiving end which you can invoke through Ajax; from that point you can execute any Java code you want.

  • Help with calling java functions from javascript

    I am using javax.script to interpret javascript from a java applet. it loads the js file into a string, and then does engine.eval(script_string). My question is, how would I make functions in the class file that are available to javascript?
    Update: Instead of that, I am loading a js script that will contain all of the usable functions. Here it is:
    //core.js for Javasphere 0.31
    var pkgs = new JavaImporter(java.lang, java.lang.System, java.awt);
    with(pkgs) {
    function Abort(msg) {
            var graph = new Graphics();
            g = graph.getgraphics();
            g.drawString(msg, 20, 20);
    }When I do engine.eval("Abort(\"something\")"); it throws this error:
    javax.script.ScriptException: sun.org.mozilla.javascript.internal.EvaluatorException: error instantiating (0): class java.awt.Graphics is interface or abstract (<Unknown source>#8) in <Unknown source> at line number 8

    Eggbertx, let's start from scratch if you don't mind. Say you have this Applet
    pubic class MyApplet extends Applet
      String message;
      //CALL THIS METHOD FROM JAVASCRIPT
      public void setMessage(String msg)
        message = msg;
        // this saves you from having
        // to call getGraphics() from JavaScript
        repaint();
      public void paint(Graphics g)
        g.drawString(message, 10, 30);
    }Then in your HTML file you may have something like this:
    <input type="text" id="msg" value=""></input>
    <input type="button" value="Set Message" onclick="setAppletMessage()"></input>
    <applet id="myApplet" code="MyApplet.class" width="400" height="100"></applet>And in the JavaScript file:function setAppletMessage()
      var msg = document.getElementById("msg").value;
      document.myApplet.setMessage(msg);
    }This is about all you really need to do. See how the Graphics object is no longer in your .js file?
    Note: You may run into other difficulties in getting this code to work because of browser, security, or some other pain-in-the-neck issues, but this is the idea.
    Eggbertx, I see you added a star to my first post and I think you should take that off because:
    1. <tt>Component</tt> is abstract... so you can not call the <tt>new</tt> operator.
    2. The call <tt>component.getGraphics()</tt> is not going to work either, because <tt>component</tt> was never created.

  • JavaFX : How to call java function that returns hashtable and manipulate

    I have a requirement to {color:#0000ff}create a java object in JavaFX script code{color}. Then call a java function using the created java object. The java function returns hashtable. Then traverse through each element of hashtable. Finally I need to create a similar structure in JavaFX.

    If you need to use a Java class that uses generics you need to take special steps. Since JavaFX does not support generics you need to create a java wrapper to hide the calls that use generics and call the wrapper class from FX.

  • How to call java method on page load?

    How to call java method on page load?
    Thanks

    Hey Dan,
    Well, if you want to execute a java method when page is load, you need to put the clientlistener in af:document. Let me to show you an example (I can't find my post :P),
    JSPX page:
    <f:view>
    <af:document>
    <f:verbatim>
    <script>
        function loadPage(event) {
            alert('Hello World!');
    </script>
    </f:verbatim>
    <af:clientListener method="loadPage" type="load"/>
    </af:document>
    </f:view>If you try this code you can see that when the page has been load, you recieve the alert "Hello World!".
    Furthermore, this is the javascript AJAX function that let you to call a servlet:
    function ajaxFunction () {
        var httpRequest;
        if (window.XMLHttpRequest) {
            httpRequest = new XMLHttpRequest();
        } else if (window.ActiveXObject) {
            httpRequest = new ActiveXObject("Microsoft.XMLHTTP");
            httpRequest.overrideMimeType('text/xml');
        httpRequest.onreadystatechange = function() { alertContents(httpRequest); };
        httpRequest.open('GET', '/appname/servletname', false);
        httpRequest.send('');
    function alertContents(httpRequest) {
        if (httpRequest.readyState == 4) {
            if (!httpRequest.status == 200) {
                alert('Request error. Http code: ' + httpRequest.status);
    }Where 'appname' is your application name and 'servletname' is the name of the servlet that you want to call. Obviously, you can call any URL ;)

  • ABAP Calling JAVA Function or Method

    Hi Friend,
    I need help in how to proceed using  ABAP  and Call JAVA Function . I know that  we need to use RFC enabled Function modules. I was able to connect  using JAVA Connector which was provided by SAP For communicating with JAVA Apps. The approach for connecting the JAVA to SAP is working fine.  But I  have browsed through various website but failed to find any information.Now i am looking forward to help from you friends to solve my problems .
    The Requirement is mentioned below:-
      1. Prerequiste for SAP ABAP calling a third Party software which is working in JAVA Platform (like any middle ware which might be hardware or software).
      2. Sample Code  like calling a Text  ' Hello  to the world  calling JAVA from ABAP'.
      3. Steps and process so that it would be helpful.
    Timely help would be appreciated.
    Rajiv Christopher.

    1.Middleware is JCO RFC provider it comes with SAP so no need any third party Adapter.
    2.
    " The ECHOTXT parameter should contain the text of REQUTXT.Information on
    " calling the function module should be returned in RESPTXT, indicating, for
    " example, in which system and when the function module call was processed.
    data:ECHOTEXT type SY-LISEL,
