Problem in getting the bpel payload

Hi,
When I'm trying to read the contents of BPELInputVariable (message type) via com.oracle.bpel.client.IInstanceHandle.getField("bpelVariableName") API,I am getting an empty hashmap whereas for all other message type variables in that bpel, the returned object is a Map and I can get the Element via map.get("partName").If I use some assign activity and assign some value to this input variable at some later point of time, the getField(inputVariable) gives the payolad.
Could you help me in finding the reason for this strange behaviour?
Thanks,
Shyamala

Hi,
can you please check the namespace of your input variable?
Can you assign the input to another variable?

  • How to get the input payload passed to the BPEL Process using java.

    Hi all,
    I am working on an application in which, if some fault occurs in the flow I need to insert the input payload that is being sent to the BPEL process into a Queue using Java. I have gone through the FaultHandling framework and failed to find the method by which we can get the input payload. Can someone kindly help me in getting the input payload. using the java.
    Regards

    Hi,
    Use method getVariableData with your input variable.
    Object getVariableData(String name, String part, String query)
    For example: getVariableData("input", "payload", "/");

  • Problem in getting the database connection from a connection pool

    Hai All,
    I am facing a problem in getting the database connection from a connection pool created on weblogic server 8.1.
    I am using the Oracle database 8.1.7.
    I have configured my connection pool, datasource and JNDI in weblogic.
    In my java program i have the following code to retrieve the connection.
    import java.sql.*;    
    import java.util.Hashtable;
    import javax.naming.Context;
    import javax.naming.InitialContext;
    class jdbcshp1 {
        public static void main(String[] args) {
         Connection connection = null;
         try {
               Hashtable ht = new Hashtable();
               ht.put(Context.INITIAL_CONTEXT_FACTORY,"weblogic.jndi.WLInitialContextFactory");  // Wanna get rid of this.
               ht.put(Context.PROVIDER_URL,"t3://localhost:7001"); // wanna get rid of this.
               // Get a context for the JNDI look up
               Context ctx = new InitialContext(ht);
            javax.sql.DataSource ds = (javax.sql.DataSource) ctx.lookup ("myjndi1");
              //Create a connection object
              connection = ds.getConnection();
         The above code is working fine but, the two ht.put statements are creating problem.
    The problem is, after converting the application into WAR file it can be deployed
    on any machine or different port on same machine. My application fails if its deployed on
    weglogicserver which is at different port.
    Is there any way that i can get rid of those ht.put statements or any other way to solve the problem.
    any help is appreciated.
    Thanks in advance
    Pooja.

    Hai All,
    Firstly, thanks for ur reply.
    Even i have seen some code which uses context constructor with out any parameter and works fine.
    i dont understand why its not working for my code.
    When i remove those ht.put code and use context constructor with out any parameter, it giving an error.
    Context ctx = new InitialContext();
    javax.sql.DataSource ds = (javax.sql.DataSource) ctx.lookup ("ocjndi");
    connection = ds.getConnection();The error is as follows:
    javax.naming.NoInitialContextException: Need to specify class name in environment or system property, or as an applet parameter, or in an application resource file: java.naming.factory.initial
    the above error is forcing me to include those code but if the port number is changed the code will not work. Plz let meknow if some setting have to be made.
    I appreciate all ur valuable help.
    Thanks once again.
    Pooja.

    This sounds like a bug in the smart upload code. I have used this stuff before, but it's probably an older version, so maybe they broke something. Enumerations aren't usually guaranteed to keep things in any particular order. I would say for now, make a method to take the enumeration and a param name to find the value. And write to the JSPSmart people.

  • How to get the XML Payload of called process from calling process?

    I have two SOA processes say process A and process B.
    Process B is called by process A.In process A I, am using the getRequestMessage() method in Java code to get the XML payload of process A.
    But i want the XML payload of process B in process A.How can i achieve it?

    Doug,
              I used the property loader method but I could not load the limits of any sub sequence call calling an external sequence file.
    I took the FlowRate_test.seq example from the NI Example folder "C:\Documents and Settings\All Users\Documents\National Instruments\TestStand 4.2.1\Examples\PropertyLoader\LoadingLimits\LimitsFromExcelFile\UsingCVI". I created a sequence called PumpTest.seq in the same folder path. I then moved the Pump Test step from the FlowRate_test.seq to the PumpTest.seq. Now created a sequence call in the FlowRate_test.seq and called the PumpTest.Seq as the module path. When I execute the FlowRate_test.seq , I get the error as shown below:
    Attached is the Flowrate_Test.seq and the PumpTest.seq which should be there in the folder path "C:\Documents and Settings\All Users\Documents\National Instruments\TestStand 4.2.1\Examples\PropertyLoader\LoadingLimits\LimitsFromExcelFile\UsingCVI".
    Let me know whether I am doing something wrong in this method. 
    My idea is to alter the runstate variable High and Low of Pump Test in the PumpTest.seq and then run the Flowrate_Test.seq.
    Attachments:
    PumpTest.seq ‏6 KB
    FlowRate_test.seq ‏11 KB

    i have on my ipad2 and re-download it - but I can't afford to loose the presentation that I currently have ....??
    Are you using Keynote on an iPad?
    If so you posted in the wrong forum, this is the Keynote Mac discussion and it is a different application. I dont know how the iPad works at all, so I cant help you, post in the Keynote iOS discussion.
    If you are using a Mac, the colours palette is accesed by clicking on the colour well (arrowed) and then selecting a colour chip or changing the color in the colour wheel.

  • Having problem to get the value from radio button

    i am doing my double module project for my degree course and i am also a newbie in JSP. Hope there is someone can help me to solve this problem. Now, i set the value of a radio button to "don't smoke", "smoke lightly", and "smoke heavily". Then i use request.getParameter ("smoking behavior") to get the value selected by the user, but the result is only "don't" or "smoke", which the character after spacing will be not be retrieved. I dun know how to solve it, so can any expert here help me to solve this problem? Thanks for helping.

    Why do you have to use whitespace. If your radio button group is name smokingBehavior - no whitespace, wouldn't it just make sence to have values of don't, lightly and heavily. This would solve the problem easily. If your teacher is being a pain in the a&!, and requires you to use whitespace for your naming variables I guess you could insert %20 between the two words and unescape the value on the server side. This seems like a lot of unnecessary work and a silly solution - good luck!

  • A problem to get the value of a selected cell

    Hi all,
    I am trying to get the value of a cell in JTable. The problem that I have is ListSelectionListener only listens if the selection changes(valueChanged method).
    It means that if I select apple then rum, only rowSelectionModel is triggered, which means I do not get the index of the column from selectionModel of ColumnModel.
    apple orange plum
    rum sky blue
    This is a piece of code from JTable tutorial that I modified by adding
    selRow and selCol variables to keep track of the location so that I can get the value of the selected cell.
    Thank you.
    if (ALLOW_ROW_SELECTION) { // true by default
    ListSelectionModel rowSM = table.getSelectionModel();
    rowSM.addListSelectionListener(new ListSelectionListener() {
    public void valueChanged(ListSelectionEvent e) {
    if (e.getValueIsAdjusting()) return;
    ListSelectionModel lsm = (ListSelectionModel)e.getSource();
    if (lsm.isSelectionEmpty()) {
    System.out.println("No rows are selected.");
    } else {
    int selectedRow = lsm.getMinSelectionIndex();
    selRow = selectedRow;
    System.out.println("Row " + selectedRow + " is now selected.");
    else {
    table.setRowSelectionAllowed(false);
    if (ALLOW_COLUMN_SELECTION) { // false by default
    if (ALLOW_ROW_SELECTION) {
    table.setCellSelectionEnabled(true);
    table.setColumnSelectionAllowed(true);
    ListSelectionModel colSM = table.getColumnModel().getSelectionModel();
    colSM.addListSelectionListener(new ListSelectionListener() {
    public void valueChanged(ListSelectionEvent e) {
    //Ignore extra messages.
    if (e.getValueIsAdjusting()) return;
    ListSelectionModel lsm = (ListSelectionModel)e.getSource();
    if (lsm.isSelectionEmpty()) {
    System.out.println("No columns are selected.");
    } else {
    int selectedCol = lsm.getMinSelectionIndex();
    selCol = selectedCol;
    System.out.println("Column " + selCol + " is now selected.");
    System.out.println("Row " + selRow + " is now selected.");
    javax.swing.table.TableModel model = table.getModel();
    // I get the value here
    System.out.println("Value: "+model.getValueAt(selRow,selCol));
    }

    maybe you can try with :
    table.getSelectedColumn()
    table.getSelectedRow()
    :)

    FILE1 = path.txt (240)
    FILE2 = WS_FTP.LOG (146)
    Display information about Requests
    radio = Value 2
    mySimpleSelect = Value 1
    myTextArea = test
    myPASSWORD =
    myMultSelect = Value 3
    myHidden = hidden
    myText = test
    myCheckBox = Value 1
    myCheckBox = Value 2
    myCheckBox = Value 3
    I would like to know if i want to get back the parameters from the form ,
    is that i must use Enumeration.
    Because i have tried request.getParameter() to get the value of radio button, textbox, checkbox and select menu, but it get the null values.
    Also, the function of Enumeration does not get the values of parameter in sequence as html form. e.g.In the html file, the first parameters should be textbox,but it displays the radio button's values first.
    How to solve the problem .
    Thanks

    This sounds like a bug in the smart upload code. I have used this stuff before, but it's probably an older version, so maybe they broke something. Enumerations aren't usually guaranteed to keep things in any particular order. I would say for now, make a method to take the enumeration and a param name to find the value. And write to the JSPSmart people.

    When trying to uninstall iTune (because the current install has problems; iTune error message states it cannot sync and that I should reinstall the application; also, it fails when I tried to upgrade to the latest release), I get the error message 2324.  What should I do to reinstall the application?

    That installer error is a "Can't open file" error
    It suggest that you may have a corrupt file.
    Try running a disk check

    If it fixes errors try uninstalling iTunes again.
    If that doesn't work, is it possible for find out the name of the problem file, is further information available? Try looking in your Action center - that's on the control panel. Another place is in the Windows Error logs. From the start menu , right click on "Computer" and select manage, then Event viewer.
    If nothing emerges, try a manual uninstall of iTunes and related programs according to this method:

    Don't worry if an uninstall fails, that is expected. Go on to the part where you have to delete files (2. Verify iTunes etc completely deleted) . Hopefully you manage to find a file that can't be deleted, that is the one we will need to deal with.
