          shell.setText("XMPPClient v1.0");
          XMPPClient thisClass = new XMPPClient(shell, SWT.NONE);
          shell.open();
          while (!shell.isDisposed()) {

  • Calling BIP from Oracle Forms: Having Java version problem.

    Hi,
    I tried to call a BIP report through Oracle Forms.

    Since we are using the Oracle JVM, ticking “Use JRE 1.5..” in the Advanced tab of the Internet Explorer Options has no effect.
    We cannot upgrade the Oracle JInitiator to a 1.5 since there is no such JInitiator version. JInitiator is available only up to 1.3.1.30.
    What can I do. What if I install Java 1.3 in my machine and re-compile my JAR file with that? Will that work or is there another solution?
    Has anybody encountered this problem?
    Any help would be greatly appreciated.

    Hi,
    Yes, you need to compile your source files with JDK 1.3 (since JInit 1.3.x.x uses JDK 1.3).
    Other solution would be to use JRE 1.5 (instead of JInitiator).
    Check out [this thread|http://forums.oracle.com/forums/thread.jspa?threadID=550563] on how to use JRE1.5

  • Can we call a workflow form a JSP and/or form a Java Class?

    Is it possible to call a workflow form a JSP and/or form a Java Class?

    Below is some xpress code I wrote once, used to dynamically lauch workflows from within a workflow. Since it basically uses java classes, you reuse these in your java program or jsp:
    - create a new generic object
    - call the setId, put, ... methods on it
    - set the input variables for the workflow by putting them into the generic object
    - call the checkinView method on a LighthouseContext object which launches your workflow.
    If all you need is starting a workflow from a jsp, you might also want to take a look at the tasks/taskLaunch.jsp jsp. This is an out of the box jsp which allows launching of tasks. If I remember correctly you have to give an url parameter which specificies the name of task you want to start: tasks/taskLaunch.jsp?id=<workflow-name>

    Hi
    You dont need JInitiator, just downloading and installing either JRE or JDK 1.5 will be enough.
    Another option might be to set the version you want to compile your classes against in JDeveloper. there is a setting in there to specify the java version you want to compile against.
    So are you using the web services from BIP inside Forms?

  • Calling a Java Script form a Java class

    Hi All,
    I am having a project requirement of calling a Javascript from a java program. Here it goes...
    I have an external web page which I can access using a hyperlink this page is "Export to PDF" page. In this page we have an "EXPORT" button which on click calls a "do_export" javascript function. On clicking the EXPORT button a PDF is generated.
    Now my problem is I do not have the access to the code, so what I can do is to some how open that webpage and then execute that javascript function form a Java program or a JSP file or even a shell script file.
    It will be a great help if anyone can assist me to do it, I have been working on this from last 7 day, but still no sucess :('.
    Thanks in advance,

    Yes I had view the source code from browser, and its calling Export function, but my question is how to call that javascript function after getting the page loaded by a JSP or java program.
    I had to automate this export process and the only thing I had is this external URL or web page.If it is just a plain javascript function that does not interact with the browser environment (window and such objects)
    you can just run it using [javax.script ^API^|http://java.sun.com/javase/6/docs/api/javax/script/package-summary.html]

  • Calling infobus form from another.

    Hi
    Here is a brief description of the problem.
    A simple data form is created using JDeveloper2.0's wizard. It is an Infobus based dataframe,which has a simple gridcontrol fetching data from the dept table. This form is in the pacakge,
    package1.
    Another form is made with a master detail relationship between dept and employee table, in the package, package2.
    Now a button control is added on the first form( which is in package1) and the following code is added to the actionperformed event.
    void buttonControl1_actionPerformed(ActionEvent e) {
    Frame f = new package2.Frame1();
    f.show();
    Essentially, it calls the form in package2 when the button is pressed. Once this action is performed, the login dialog box of the form in package2 appears. After which it throws the following error and shows a blank form.
    DAC-405: SessionInfo: Application module creation failed; className: ConnectionTrade
    JBO-00200: A Generic exception occurred during loading Customizations.
    null
    If I add a button in the second form, (ie. the one in pacage2 having a master detail relationship) and call dept form (in package1) from here, it works.
    We are stuck with this problem, and unable to proceed with deploying the application. As each form need to be called and invoked from a menu.
    Thanks in advance.
    Ravi

    Hi,
    You can do like this :
    mainApplication(Menu)
    +------------ Frame1
    |
    +------------ Frame2
    In MainApp you call your frame, and remove from code the
    windowListener of the frame. Replace the dispose(); in frame
    methods fileExit(ActionEvent e) & processWindowEvent(WindowEvent
    e), by try { finalize(); } catch (java.lang.Throwable ex) {
    ex.getMessage(); }
    It works great.

    Hi,
    this is the way i am showing a password dialog: i derive this class from JDialog (not from JFrame).
    In its constructor, i make it a modal dialog.
    public class PasswordDlg extends JDialog {
    private boolean ok; // this flag should indicate whether the User has pressed OK or CANCEL
                                 // i omit the code for OK and CANCEL here...
    public PasswordDlg(JFrame owner, String DisplayText) {
         super(owner,DisplayText,true); // true -> modal!
      public boolean showDialog()
        { ok = false;
          show();
          return ok;}
    } Now in my main frame (this is derived from JFrame) in its constructor, i make an instance of my PasswordDlg, call its showDialog method, ask the password from the dialog (i have omitted this method), and then i decide, whether the program should go on or whether i call System.exit(0) in case the password is wrong.
    regards

  • How to call a form in Oracle Portal?

    I'm trying to call a form from my corporate Oracle Portal. Can anyone advice me how to do it?
    Thanks and Regards.

    Alex,
    you are not providing enough information, making it not easy to provide a short answer without going down the whole tree of possibilities.
    Case1: You want it appear as a link in Oracle Portal.
    a) You can use the "myfavorite" portlet, which is a kind of bookmark list that can be managed by each user individually.
    b) you ca create a content area and make it to appear as a type URL. Then you define it as a portlet.
    c) You create a HTML page with all the forms links in it and use the URLServices portlet or teh HTML portlet
    Case2: You want it to appear within the portal as a portlet.
    In this case you choose the URL Services. URL services are a part of the Portal Development Kit and in there a part of the Java Portal Development kit.
    It is not recommended to integrate Forms as a Portlet in Portal (CASE2) but to start it from a link (CASE 1) for this reasons:
    - http accept-header misses Browser type information information
    - Forms startup time slows down portal page startup
    - SSO doesn't work straight away
    - Forms9i, because based on java 1.3, will reload Forms when reloading the portal page, loosing the application context (this is not yet an issue with Forms6i).
    Of course, you can have it working as a portlet and I did it in the past, but it will require some work to do that is not yet documented (and probably never will).
    Cheers

  • Calling Adobe form in a Workflow Step for approval

    Hello,
       There are some ISR forms and workflows in MSS which use Workflow tasks configured as JavaWebDynpro to call Adobe form from the Workflow Step.
    Is it possible to achieve the same using ABAP Web Dynpro and creating a new task and configuring to use it as an ABAP Web Dynpro (which can in turn call the Adobe form from the WD)?
    Thanks.

    Hi Anjali,
    1)You can develop an<b> RFC</b> that collects required basic data from R/3 and display them in <i>ABAP WD - Adobe Form</i>. The End user can change/fill the remaining contents of the Adobe Form and submits it for approval. The <b>RFC</b> again handles the triggering part of the <b>Workflow</b> and passes the form data to the workflow containers.And for approvals, you can use the <i><b>SWFVISU</b></i> to call a <b>ABAP WD</b> application from Workflow. And in turn the control again goes back to RFC and so...
    2)I dont have much idea in ECC 60 if there is a similar ABAP WD application like Standard Java WD <b>IsrFormApprove</b>.
    3)No idea.
    Regards,
    <i><b>Raja Sekhar</b></i>

  • Calling multiple DLL from Java and calling same native method

    i have two dll files named DLL_1.dll and DLL_2.dll .
    Both of them contain a native method which has a signature
    JNIEXPORT void JNICALL Java_Database_Notify
    (JNIEnv *, jclass);
    This method is common to both the DLL
    Now i load both of the DLL's using,
    System.loadLibrary("DLL_1");
    System.loadLibrary("DLL_2");
    Both of the DLL are loaded form same Java Application
    But the problem is that , whenever i try to call the Notify Method , it calls the Notify method of DLL_1 only.
    How do i call the Notify Methos of second DLL(i.e DLL_2).
    Is there any reference that i can get to all the DLL files when i load then , so that i can use that reference to invoke the Notify method of that particular DLL.

    As per the description above it is impossible in java.
    And I didn't say JNI, I said java.
    Your above statement suggests that you think that you can have exactly the same java signature do two different things.
    Note again that I said java not JNI.
    A JNI method is just a tag that represents a java signature. Your description suggests that you are attempting to do it twice.
    There are three possibilities.
    1. Your explanation is incomplete.
    2. You are trying to do something that is impossible in java.
    3. You are trying to solve a problem and your description of your solution is not sufficient to determine what that is (and of course the solution is wrong.)

  • Compiled and trying to deploy a form - an error when calling the form

    Hi!
    I used to deal with Forms 6i and I'm quite new to 10g.
    Is it enough to just replace an .fmx file on the server?
    We have a software product written on Forms 10g which is running on our server.
    I found where working .fmx files are located on the server.
    I also found which seems to be the source files.
    My actions:
    1) Selected one of the forms and compiled it in Bulder 10g successfully.
    2) Replaced an .fmx file with one which I had comiled.
    3) In user interface, press the button which calls my form, but nothing happens. The form is not created. No error messages.
    4) Put the original .fmx back - and everyting works: after pressing the button the form starts.
    What's wrong? Improper way of compilation or deployment?
    Any suggestion would be appreciated.
    Thanking in advance,
    Roman

    Thank you, Christian!
    You are right!
    According to my last test, when I try to call the form directly from the url (via parameter form=myform.fmx), I get the following:
    1) With the orginal myform.fmx, the form starts
    2) With the form compiled by me, I get error: "Cannot read form myform.fmx"
    Though the file names are identical, the file compiled on windows doesn't go.
    P. S.
    Nevertheless, that's weird for me: I supposed that since Forms 10g is based on Java, the compilation must be platform-independent.
    Edited by: Roman Churakov on 20.01.2012 1:58I think you have just a problem with upper/lowercase.
    .) ensure your fmx is exactly myform.fmx
    I am not sure but I think you get this message also if there is a wrong attached-library-name in the source.
    So if its still not working convert the fmb to text (file->convert...), check if the libraries are attached correctly (case sensitive on UX/LX) the libs are visible in the first lines, check if some libs are attached multiple times, correct that stuff, and convert back from text to fmb.
    Hope that helps!

    Hi Sergei,
    I've just finished a three day search for a FRM-92101problem, so I want to post my case, just in case it helps someone.
    My case is similar to yours, in that you have a Forms 6i form migrated to 10g and deployed on Linux, although my problem was "very" specific, and thus very hard to find, this might give you some light.
    I had a visual attribute that defined the property "Fill Pattern" as "none" applied to a canvas, and it deployed without any problem on 10gR2/Windows, but when deployed on Linux (10gR2/SUSE 9) it would abort the application getting a FRM-92101.
    The solution in this case was just changing "none" to "Transparent".
    Hope this helps.
    Regards,
    Miguel.
