Sybase (SUP) - Blackberry - Native - LoginToSync Nullpointer

All,

We are creating a Blackberry native application linked with Sybase.

At this point we have a Blackberry project with the correct .jar files linked and the correct files of the generated code.

The MDS is also running...

But when i am excuting the following code:

TestDB.loginToSync("supAdmin", "s3pAdmin");

We get a nullpointer exception and nothing happens...

Does anybody have an idea?

Thanks!
