Record level access problem

Hi people,

I debuged my simple java program in the following and found it stopped when it 
reached  "RecordFormat fmt = new AS400FileRecordDescription()" statement. Can 
anyone tell me what the possible problem is? The ports drda, 
as-signon,as-srvmap etc have already opened in AS400.

FYI, I have followed the troubleshooting tips in 
http://www-1.ibm.com/servers/eserver/iseries/toolbox/troubleshooting.htm, but 
still can't solve the problem.

Thanks in advance,

Rong
