Call enhancement class method from Bus. workflow task

Hi all,
I recently enhanced a global class from SAP (add a new method). Now I would like to call it from a workflow task (ABAP Class object used in the task). So it seems that only "native" methods from the class itself can be selected for the object method of the task.
Same issue if I try to call it via secondary methods options...
Last idea I have before the repair is: retrieve the instance saved into the WF container via a custom class interfacing IF_IFS_SWF_CONTAINER_EXIT (program exit) and call the enhanced method from the method proposed in this interface.
Maybe someone had the same issue? Anyone could help or propose solution?
Many thanks in advance for your help,
KR,
Olivier

I think it might qualify for an OSS message.
There was simmilar note for BADIs which was corrected: https://service.sap.com/sap/support/notes/1156392
CL_SWF_UTL_DEF_SERVICES which is used in PFTC to determine callable methods doesn't include enhancements when calling  function SEO_CLASS_TYPEINFO_GET (parameter WITH_ENHANCEMENTS is default FALSE)

  • Calling ABAP class methods from JAVA application

    Hi All,
    I want to fetch ITS related information (SITSPMON Tcode) in my JAVA application. But i didnt find much BAPIs for the same. While debugging I came accross few class methods with help of which I can get the required information. So is there any way we can call and execute methods of ABAP classes through java application?
    for e.g. I want to call GET_VERSION method of CL_ITSP_UTIL class.
    Thanks,
    Arati.

    Hi,
    Yes, as per my knowledge the only way to interact is using BAPI exposed as RFCs. So try to invoke those class methods in one CUSTOM BAPI and expose that BAPI as RFC and consume that RFC to get those details.

  • Calling public class method  from the servlet dopost() implementation

    Hi!
    My application is a simple application where i wrote a JSP page to enter the USERNAME and PASSWORD. And this JSP will call a HttpServlet
    with in which i am calling another Java class ValidateUser which will check aginst the Oracle Database table whether that Username and password combination exists and returns the user's name.
    But when i am trying to call that method is throwing me an error. here is the typical code i wrote.
    servlet

    import javax.servlet.*;

    One more thing i forgot to tell you. I am trying to run this application on JDeveloper. Please helpme out if you can . Thank you.
    -Sreekanth

    OK! I made it static method
    and tried to call the method as follows
    String uName = ValidateUser.ValidateUser(userId, password);
    even if i create the instence and
    ValidateUser Validate;
    then call
    String uName= Validate.ValidateUser(userId,password)
    In either case is giving me the following error.Tarun, am new to Java programming, please help me out. And can you please tell me where can i find things in consise to brush up my fundamentals?.

    Hi All,

    Can anyone provide me the clarification , why system behaving like this.

    Hi,
    I think you can not.
    Because, only public attributes can be inherited and they will remain public in the subclass.

    Read through your text book or some java tutorials from this site to understand what classes are, what are methods, etc.
    Your program is full of wrong initializations (as you rightly said you dont understand how to call up class method I would add that you dont understand how to call classes and what do they return e.g.
    You have declared
    String p;
    then you go ahead and do this
    p = new Product("manuf","name","quantity","price"); This is syntax for calling a class is this class returning a String? :s
    Please go through the basics of Object Oriented Programming and then start with the coding part else you will face such very many difficulties and waste more time of yours in just coding with no results.
    Look for the tutorials on this site and read through them and do example as given in them.

  • Calling a service method from a DataAction

    Hello!
    I'm trying to call a service method from a DataAction, cobbling ideas from the Oracle JDeveloper 10g Handbook and the Oracle ADF Data Binding Primer.
    I have created a service method and exposed it using the client interface node of the application module editor. It is called "process()" and it now appears in the data control palette under MyAppDataControl->Operations (just above the built-in action bindings Commit and Rollback). As part of this procedure, I modified MyAppImpl.java and put the process() method there.
    I don't want to call process() by dragging and dropping it onto a Data Action because depending on the outcome, I want to branch to different pages. process() returns an int that will tell me where to branch. Thus, I am trying to call it from an overridden invokeCustomMethod() method of the lifecycle of a DataAction, where I can get the int, create a new ActionForward, and set it in the DataActionContext. (If I'm barking up the wrong tree, let me know!)
    So, I need to call MyAppImpl.process() from within the invokeCustomMethod() method of my DataAction. Looking at the class declaration, I noticed that it extends ApplicationModuleImpl. I figure that, if I can get the ApplicationModule, I can cast it to MyAppImpl and call the process() method. Unfortunately, that doesn't work. When I got the application module, I checked the class and it's oracle.jbo.common.ws.WSApplicationModuleImpl. I tried casting it and got a class cast exception.
    Here's the code I'm using:
    protected void invokeCustomMethod(DataActionContext actionContext) {
    BindingContext ctx = actionContext.getBindingContext();
    DCDataControl dc = ctx.findDataControl("MyAppDataControl");
    log.debug("invokeCustomMethod(): dc.getClass().getName()=" + dc.getClass().getName()); // result is: oracle.jbo.uicli.binding.JUApplication
    ApplicationModule am = null;
    MyAppImpl myAppImpl = null;
    int processResult = 0;
    if (dc instanceof DCJboDataControl) { // this is true
    am = dc.getApplicationModule();
    log.debug("invokeCustomMethod(): am.getClass().getName()=" + am.getClass().getName()); // result is: oracle.jbo.common.ws.WSApplicaitonModuleImpl
    if (am instanceof ApplicationModuleImpl) { // this is false
    log.debug("invokeCustomMethod(): am is an instanceof ApplicationModuleImpl.");
    if (am instanceof MyAppImpl) { // this is false
    log.debug("invokeCustomMethod(): am is an instanceof MyAppImpl.");
    processResult = ((MyAppImpl)am).process();
    log.debug("invokeCustomMethod(): processResult=" + processResult);
    super.invokeCustomMethod(actionContext);
    What am I doing wrong? Can anyone explain the different class hierarchies and why my application module isn't the class I'm expecting?
    Thanks,
    -Anthony Carlos

    Georg,
    it was in the javadoc of oracle.adf.model.binding.DCBindingContainer
    http://www.oracle.com/webapps/online-help/jdeveloper/10.1.2/state/content/vtTopicFile.bc4jjavadoc36%7Crt%7Coracle%7Cadf%7Cmodel%7Cbinding%7CDCBindingContainer%7Ehtml/navId.4/navSetId._/
    However, I see it's not the case in other sub-classes of JboAbstractMap like DCControlBinding and DCDataControl.
    Weird... I'm keeping you informed if I find more information.
    Regards,
    Didier.

  • Problem calling a Java Method from C++

    hi everyone,
    i'm using JNI and i'm trying to call a Java method from C++, this is the code:
    SocketC.java

    when i'm running the proyect i get this error:
    C:\POT Files\UCAB\tesis\esmart\french>java SocketC
    Exception in thread "main" java.lang.NoSuchMethodError: recibeBuffer
    at SocketC.conectaServidor(Native Method)
    at SocketC.main(SocketC.java:16)
    i don't know why this is happening i got declare the method recibeBuffer in my SocketC.java class, but doesn;t work can anyone help me?
    PD: sorry for my bad english i'm from Venezuela

    Next time please paste your code between &#91;code&#93; tags with the code button just above the edit message area.
    To answer your question, you wrote the wrong method signature. It should be:jmethodID mmid = env->GetMethodID(cls, "recibeBuffer", "()V");Regards

  • How to call a bean method from javascript event

    Hi,
    I could not find material on how to call a bean method from javascript, any help would be appreciated.
    Ralph

    Hi,
    Basically, I would like to call a method that I have written in the page java bean, or in the session bean, or application bean, or an external bean, from the javascript events (mouseover, on click, etc...) of a ui jsf component. I.e., I would like to take an action when a user clicks in a column in a datatable.
    Cheers,
    Ralph
