Can't retrieve data dictionary items in 8.0.5 DB from Powerbuilder

Question

Hello all,
I'm using Powerbuilder 7.0 in an actual project.
The database is Oracle 8.0.5.1.0 for Linux (Distribution is SuSE 6.0)
There's some strange behaviour which prevents developing with the database:
- Connected as user system in Powerbuilder. No problems during connect. Trace activated.
- Appears grapical table list. When trying to retrieve column attributes of selected table Powerbuilder hangs. The grants on the selected dictionary views have been checked and user system has been granted role dba.
These are the traced statements Only the last one doesn't work - doesn't come back with a result.

I've rerun CATALOG.SQL and CATPROC.SQL; I've installed an 8.0.5-Database under NT and had no problem.
A collegue working with the Java IDE Forti and connecting with JDBC has a very similar problem.
At the moment the project can't go on because of this problem.
Any hint would be welcome
Thanks

Hi all, thx for your reply, i have found where is my error :)
In dbSelectUniqueRow() method,
//put the attr value into arrayList                               
for(int j=1; j<=fieldList.size(); j++) {                                       
columnValues.add((String)rs.getObject(j));
  }i shouldn't put all the value into the arrayList, instead i should put in the primary key,
Then in client side, I can cast it to remoteInterface. After that, i can retrieve the value in client using
Staff s = (Staff)home.FindByName("XXX");
