Hi all!
I have a problem with javax.transaction.UserTransaction and I see
no solution so far.
The problem only arises, iff I run my application as Applet in a
Browser (IE or NS, dosn't matter).
I can not get an Instance of UserTranscation, neither with a narrow()
(this returns an Instance of javax.naming.Reference) nor
with NamingManager.getObjectInstance() (returns also a Reference)
If I run the Application as Java Application (not as Applet)
I do not have this Problems, I just can use
PortableRemoteObject.narrow()
to get an Instance of UserTransaction.
One more thing, we use HTTP tunneling if we run the Applet.
For details, please se the following code
Thanks, Max
----------------- CODE -------------------
protected AbstractImportController(Context aInitialContext)
throws NamingException, RemoteException, CreateException,
Exception {
home = (DataImportHome) PortableRemoteObject.narrow(
initialContext.lookup("DataImportHome"),
DataImportHome.class);
// home is OK
Object obj = null;
try {
obj = PortableRemoteObject.narrow(
initialContext.lookup("javax.transaction.UserTransaction"),
javax.transaction.UserTransaction.class);
}
catch (Exception exc) {
exc.printStackTrace();
}
if (obj instanceof javax.naming.Reference) {
// obj is: javax.naming.Reference
Object o = NamingManager.getObjectInstance(obj, null,
aInitialContext, null);
// this fails, o is again of type javax.naming.Reference
utx = (UserTransaction) o;
}
}
