Notes/Domino 6 and 7 Forum : Java Problems

I am having trouble with the lotus.domino packages and the iSeries (as400)
I am running java 1.3 and domino 6.

My programs are stand alone I have followed the documentation on the internet and lotus/IBM websites and have the stand alone java running under qnotes.
This appears to be working fine.

When I run the java I receive the following message when the java program attempts to access the domino packages using the static NotesThread methods.

java.lang.UnknownError
lotus/domino/NotesThread.stermThread()V+9 (NotesThread.java:190)
uk/co/arcadiagroup/PCMGTIstats/NotesMail.main([Ljava/lang/String;)V+0 (NotesMail.java:21)

When have a class that extends notes thread I receive the following message
java.lang.UnknownError
lotus/domino/NotesThread.initThread()V+14 (NotesThread.java:146)
lotus/domino/NotesThread.run()V+7 (NotesThread.java:202)

It seems to me that the is a problem initialising the notes Thread. On both approaches. i am wondering why as I am using qnotes to run the program and this should have full access. I have been informed that the domino installation was a normal installation with nothing untoward done to it.

I wonder if I am still having problems connecting to the lotus.domino native api's.

Any help would be much appreciated.
