How do I debug pl/sql procedures from a bc4j application

Question

Hi,
I would like to use jdevelopers pl/sql debugging capabilities to debug some code that is executed by triggers in the database, when inserting records through my bc4j client application.
I already found the remote debugging feature of jdeveloper, but that requires setting up a separate debugger listener, and it also requires me to put the following statement in the session:
DBMS_DEBUG_JDWP.CONNECT_TCP ('hostname_or_ip', port_number)
Where and how can I put this line of pl/sql code to make it execute each time I launch the bc4j application?
Or is it possible to use one debugger process (the one that's also using the java breakpoints) to debug both pl/sql and java code?
Greetings,
Ivo

I have the same problem.
I have a PL/SQL function that returns a number. This function receives 2 parameters. I use StoredProcedureCall plus ValueReadQuery.
Session aSession = SessionManager.getManager().getDefaultSession();
StoredProcedureCall call = new StoredProcedureCall();
call.setProcedureName("CIO_UTILS.COUNT_USER_ROLES_IN_MODULE");
call.addNamedArgument("p_persid");
call.addNamedArgument("p_module");
call.addUnamedOutputArgument("rolesnum", Integer.class);
ValueReadQuery query = new ValueReadQuery();
//query.bindAllParameters();
query.setCall(call);
query.addArgument("p_persid");
query.addArgument("p_module");
Vector parameters = new Vector();
parameters.addElement(persid);
parameters.addElement(theModule);
Integer rolesnum = (Integer) aSession.executeQuery(query,parameters);
aSession.release();
if(rolesnum.intValue()<=0)return false; else return true;
However, I receive the following error:
Exception [TOPLINK-4002] (Oracle TopLink - 10g Release 3 (10.1.3.0.0) (Build 060118)): oracle.toplink.exceptions.DatabaseException
Internal Exception: java.sql.SQLException: ORA-06550: line 1, column 96:
PLS-00312: a positional parameter association may not follow a named association
ORA-06550: line 1, column 7:
PL/SQL: Statement ignored
Error Code: 6550
Call:BEGIN CIO_UTILS.COUNT_USER_ROLES_IN_MODULE(p_persid=>'SANCRA2791', p_module=>'PSL_MONITORING', ?); END;
     bind => [=> rolesnum]
If comment the line
"call.addUnamedOutputArgument("rolesnum", Integer.class);"
Toplink is trating it as a procedure, and I also receive an error from PL/SQL.
There should have to be a way of make it to receive the resoult somehow, but I do not know what.
Thanks in advance.
