How to call java file when entering the another jsp page.

when i click the link to link to another page, when enter the page, how can i call java file and passing id parameter to call method, which is connected to DB.
when enter the page, how can i call java file together with one arguement???

I would strongly suggest to go the MVC way. Please perform all DB operations through a Servlet/Action instead of directly hitting the JSP and then invoking a java bean to do the DB operation. JSP should only do the rendering.

    Hi nuttynibbles,
    Before the class declaration in partA.java, you must have an import statement like :
    import someDirectory.partB;
    public class partA {

  • How to call a concurrent program from a Custom JSP page.

    Hi,
    I have a custom JSP page which i have deployed by creating a form function with the path of the JSP Page
    and added the JSP Page to the OA_HTML top.
    Now, i need to call a concurrent program from the JSP Page, i have all the parameters in my page and i am using the standard class as below:
    ConcurrentRequest cr= new ConcurrentRequest(con);
    int requestId= cr.submitRequest("XXINV",programName,null,null,false,vec);
    I have verified my connection object and it is OK but i am getting the exception that user is not set to run the program.
    I tried the below code in my JSP page and getting -1 for all test variables :-
    int userId = wctx.getUserId();
    int respApplId = wctx.getRespApplId();
    int respId = wctx.getRespId();
    I think i need to set the context in JSP page to run the program..
    Pls help ....
    Regards
    Saurabh Jaiswal

    Hi,
    Thanks for the reply,,,
    This is a possible solution but this will allow to run the program anyhow.
    But the procedure which i call thru callable statement will start with
    fnd_global.apps_initialize (3825, 50603, 704);
    fnd_request.submit_request API call.
    Now, the values of user and Responsibilty is required in the program and it changes.
    With this approach we have to hardcode the user and resp.
    The same JSP page is attached to other responsibilities and there the concurrent program would get fired as if fired from the resp Id hardcoded as above.
    Need to capture user Id and RespId.
    How can i set the apps Context in JSP page???
    Regards

    But I don't konw what to do, Is there a function similar to the Flex's createComplete in JavaFX.
    please give me an example to show how to do that.

    DoStuff();
    Stage { scene: Scene { ... }}DoStuff() (or equivalent code at script level) will be executed first.

  • Need Sorter java  file   for sorting the records in webdynpro java

    Hi  Gurus
       I  had urgent requirement please give your inputs
       In my webdynpro java i need to sort entire records in table
       I now we need One sorter java class please provide that java file
       please suggest the all the steps how  to do
    Thanks
    renu.

    1. Implement class comparator wich will compare records according your sort preferencies,
    like this:
         public class record_Comparator implements Comparator{
              public int compare(Object emp1, Object emp2){
          // here is your code for return -1if 'before'  or 0 if equal or 1if 'after'
                   int stepId_1 = ((record)emp1).get_someValue();       
                   int stepId_2 = ((record)emp2).get_someValue();
                   if(stepId_1 > stepId_2)
                        return 1;
                   else if(stepId_1 < stepId_2)
                        return -1;
                   else
                        return 0;   
    than call method sort() with your collection of records,
    like this:
    Collections.sort(record_collection, new record_Comparator());

    Hello everyone,
    My query is..
    There is one pl/sql stored procedure which is doing some business logic and storing data in some columns of one table, suppose the table name is 'ABC' .. and the rest of columns of table ABC are getting updated using java class. Now my problem is whenever I insert data in ABC using store proc.. i have to call that java class so that it will update the rest columns ( why java class for updating the columns in ABC is ..because that logic cant be done from pl/sql proc.. it has to be done using java )
    and the other thing is.. oracle is in one machine and java is in another .. :(
    hope ..u can help me out !!
    Thank in advance !!

    For someone well versed in java, C++ and JNI although tedious that should be obvious.
    For someone not well versed in all three it is going to be very difficult.
    Even for someone that does have knowledge in all of those areas coming up with a C++ interface that reflects that functionality in a dynamic way such that anyone is will to use it is going to be quite an adventure.
    At any rate to start building it you do exactly the same thing that you would in java.
    1. Extract everything in the jar via the zip package
    2. For each found instance extract all of the methods, return types, parameters, etc and build a description tree for each class.
    Doing all of that in C++ is going to take a LOT of code. If someone wanted an estimate from me it would take me 6 months to do it. And before I would even attempt it I would get them to explain to me in detail exactly how they thought they were going to use it when I was done because I can't see any reasonable way to do that.
    I left out the description tree itself. I suppose you could duplicate the entire reflection api in C++.
    Now perhaps if it was much, much more constrained, like to only those classes that implement a single interface then that would be more reasonable.

  • 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 ;)

  • How do I share files uploaded into the Creative Cloud with other creative cloud members?

    How do I share files uploaded into the Creative Cloud with other creative cloud members?

    Should be easy.  Try this...
    In Thumbnails view, click the little triangle (pointing downward) in the lower-right corner of the asset you want to share.
    In the blue icon bar that appears, click the Share icon (the third icon from the left, just right of the trash icon). The Share dialog should pop up.
    In the Share dialog, enter the email address of the person with whom you want to share the asset, then click the Send Email button - they'll receive an email with a link to your asset. OR
    You can also copy a link to the asset and then paste that into your own email client if you prefer.  To do that, click the Link icon (looks like a "chain", and is to the right of the email "envelope" icon) - then click the Copy Link button.
    Note that the Share options won't be available if your asset is set to "Private" - you can control whether an asset can be viewed (or downloaded) by others by clicking the Public/Private control (green or red "lock" icon).
    You can also access the same Share controls if you click on the file to see it one-up (you can do this from either Thumbnails view or List view); click the Share icon near the upper right corner of the browser window (to the right of the asset name).
    Hope that helps.
