IObjectManager.lookupObjectID throwing an RMI exception

I'm having trouble with the method call IObjectManager.lookupObjectID(String UUID). Regardless of what I pass in, I get a java.rmi.RemoteException. I've even tried the following:
om.lookupObjectID(om.lookupObjectUUID(200))
I still get a RemoteException. All the other calls I'm using in the PRC, including IObjectManager.lookupObjectUUID, are working fine. Any thoughts/ideas? Anyone else seeing this problem?
Thanks!

Just FYI -- I finally figured out why this was happening. You need to be in the administrators group in order to call IObjectManager.lookupObjectID(String UUID).

WPUMFactory.getUserFactory() throws null pointer exception

Hi,
I am trying to use KM API's to read files from KM repository. I am using the below code as mentioned in the blog: How to download KM documents using Web Dynpro Java
Below is my code:
IWDClientUser wdClientUser = WDClientUser.getCurrentUser();
com.sap.security.api.IUser sapUser = wdClientUser.getSAPUser();
IUser epUser = WPUMFactory.getUserFactory().getEP5User(sapUser);
However the line WPUMFactory.getUserFactory() throws null pointer exception. Can some one please help on why these happens as these seems to be the standard code to read a file from KM.
Thanks.
Regards,
Ponraj M

Hi Ponraj ,
Instead of fetching the current logged on user , use the below line to set the resource context and see if it helps .
com.sapportals.wcm.repository.IResourceContext resourceContext = ResourceFactory.getInstance().getServiceContext("cmadmin_service");
cmadmin_service is a existing user that can be used to access KM resources .

How to throw a permanent exception during mapping?

I'm using the java coding: "throw new RuntimeException(message);" to trigger an error during mapping.
This will set the message status to: "System error, manual restart possible".
How can I throw a permanent exception during mapping? So that the message is set to error but will NOT be restartable.

Hi,
Any error in asynchronous mode in XI will be in a Restart Mode. I dont think this can be done.

Vector.clear() throws null pointer exception

is there anything wrong in my code. when i try to clear the vector irrespective of whether i add elements to it or not, if there are no elements added to the vector v1.clear() it throws null pointer exception

v1.clear()

And the guessing game continues... anyone for a shortctu to duplicate this problem?
public class NullVectorCreator
    private Vector v1;//just love the name, so clear and unambiguous... :)
    public NullVectorCreator

    public static void main(String[] args)
           NullVectorCreator nvc = new NullVectorCreator();
            nvc.getVector().clear();//Why does this throw an NPE? why? java is bugged!

Hi,
Based on your description, I don’t think that the issue is really related to Coded UI test itself. Your issue is mainly on setting a value using ValuePattern.SetValue. I think it is more related to accessibility and automation. I noticed that you post a
new thread on Windows Desktop Development for Accessibility and automation forum:
http://social.msdn.microsoft.com/Forums/windowsdesktop/en-US/8c8f4566-22df-4944-ba57-13898dcec6be/valuepatternsetvalue-throws-elementnotavailableexception-inner-exception-of?forum=windowsaccessibilityandautomation#8c8f4566-22df-4944-ba57-13898dcec6be
I am not an expert on accessibility and automation, I am sorry for that I can’t provide you something useful about ValuePattern.SetValue method’s usage. I think that community members on Windows Desktop Development for Accessibility and Automation forum
will help you resolve this issue better.
Thank you for your understanding and support.

Should a signed applet ever throw a security exception?

hi,
I've had a few times when a signed applet seems to throw a security exception (at the moment am trying to figure out a SocketException being thrown).
I thought if the applet was signed, and when the browser asks if you want to grant it permissions you press Yes (which I do), then there should not be any security issues?
thanks,
asjf

A signed applet has to assert which permissions it wants. The client JVM then asks the user if they will give those permissions to the signer. If the applet tries to do something for which it hasn't been granted permission a security exception is thrown.

How to throw a SOAP exception

Hi,
I have a requirement from customer that when they call the WSDL from their app and the workflow will not get what it should, that it should throw standard SOAP exception.
To give more details on it, they will send for example input string "A" and based on that I will return output string "B" in the process.
Now if they ask for "C" for instance, I need to be able to throw that SOAP exception. Is that possible? The process in workbench consists of simple decision point and set value activity based on route conditions.
Thanks
J.

I am assuming you are wanting something to come back as a SOAP fault element?
Unhandled process exceptions are sent back as faults. So, theoretically, you could write a service component to do nothing but throw an exception. Then you could route your process to call that in specific situations.
As an alternative, I would consider having something like an additional 'status' output variable that always came back in the response which indicated the status of your process.
Good Luck,

RMI Exception between EJB calls

Hi folks,
After adding some methods to an existing EJB, we are getting RMI exception,
as follows:
at
weblogic.rmi.extensions.AbstractRequest.sendReceive(AbstractRequest.java:76)
at
omega.fidens.ventas.WFVentaSessionBeanEOImpl_WLStub.recuperarPersona(WFVenta
SessionBeanEOImpl_WLStub.java:3328)
Our architecture is the following
1. A Statefull EJB, is calling a stateless EJB. The first one is
WFVentaSessionBean, the second , VentaSessionBean.
2. The same WF is calling another EJB, stateless also, and everything is ok.
Any hint?
Regards
Ivan

Looking at: [no sapjcorfc in java.library.path]
it seems like the environment that has the class with the method m does not have the platform dependent part of the JCO setup.
Try to create a standalone program on the same server that just uses JCO and see if it works first.
Cheers,
Kalle

Purpose of throws clause in exception handling

hi all,
I have written a sample code for exception handling...please refer below....
class a
void fun() throws ArithmeticException
int i=0;
i=10/0;
class exec
public static void main(String a[])
a a1=new a();
try{a1.fun();}
catch(ArithmeticException e){System.out.println("hi");}
}

I read the article...and came out with these points...
1..If method is throwing an unchecked exception (as in this case) then there is no need for throws clause, if you are not catching it then and there only.....
2...if a method is throwing a checked exception then either you need to catch it then and there only or you must specify a throws clause for the same in function definition......*And the purpose of not catching it then and there only is*
"For example, if you were providing the ListOfNumbers class as part of a package of classes, you probably couldn't anticipate the needs of all the users of your package. In this case, it's better to not catch the exception and to allow a method further up the call stack to handle it."
M I RIGHT??

Wehre can i find all the throw and catch exceptions

I havent had much success figuring out which predefined exceptions i should/can use. Can someone please guide me where i can find out what kind of throw and catch exceptions are there in java and how and where can i find them. thanks.

Read this first: http://java.sun.com/docs/books/jls/second_edition/html/exceptions.doc.html#44044
You can't find them all anywhere. You'll just encounter them as you use different APIs.
One of the most basic concepts around exceptions has to do with the difference between checked and unchecked exceptions. Any exception that extends RuntimeException is unchecked. Which means that if you call a method that throws an unchecked exception, you don't have to provide a catch block. These exceptions are usually thrown for things that could be avoided, i.e. programmer error.
The compiler will require you to have a catch block for all checked exceptions. This means you should take steps in your code to handle them and retry the operation, such as user errors.

Throwing Client Soap Exceptions

I am writing j2ee web services and would like to throw Client soap exceptions when a input validation error occurs. Currently I can throw a soap exception and have the msg= be set to what I would like. I cannot set the faultCode to what I would like.
An example of the kind of errors I am generating.
SOAPException: faultCode=SOAP-ENV:Server; msg=Input SSN is not valid.]
An exmpale of the kind of error I would like to generate.
SOAPException: faultCode=SOAP-ENV:Client; msg=Input SSN is not valid.]
Thank you,
David Schwartz

Hi ,
The client does not have a hook on the SOAP Fault(or for that matter , the SOAP message ).It only receives the marshalled java objects from the proxy.
You might hack the generated proxy code , and hack further into the Response objects , and the Fault object to create your customized fault .
Thanks

Throwing my own exception

I'm trying to throw my own exception but can't seem to do it. the method i'm using has three different exceptions that i need to declare. Heres my code with one exception (not working of course):
     public static String ProcessUserInput(){
          BufferedReader kbd = new BufferedReader(new InputStreamReader(System.in));
          String line = "";
          BlankException blanke = new BlankException blanke();
          try{
line = kbd.readLine();
catch (IOException ex)
System.out.println( "Error reading keyboard input." );
return line;
I've tried to throw a new exception called BlankException but i get the following error message:
'(' or '[' expected
BlankException blanke = new BlankException blanke();
How do i put three of my own exceptions in this piece of code?

how do i do that if i have three exceptions in the one methodYou can declare your method to throw as many exceptions as you want.
Example:public void method() throws CustomExceptionA, CustomExceptionB, CustomExceptionC {
    if (/* something goes wrong */) {
        throw new CustomExceptionA();
    try {
    catch(IOException ioEx) {
        throw new CustomExceptionB();
    catch(Exception ex) {
        throw new CustomExceptionC();
}
