Stored procedure fails when called through jdbc

Question

Stored procedure returns incorrect results
Hi!
I am really puzzled about this and would really appreciate some help.
We are migrating an servlet/jsp-application from websphere application server 3.5.3 to
Oracle Application Server 10g. The backend is an Oracle 9i database server. Most of the application
is build upon stored procedures in oracle. So the migration part is to make the servlets and JSPs
to work in their new environment, creating deployment descriptors and so on.
We are using JDeveloper 9.0.5.2 for development on Windows XP OS
Java version is 1.4.2_03-b02 (ojvm)
and also have an Oracle Application Server Enterprise Edition 9.0.4.0.0
running on a W2K SP6. Java version is 1.4.2_03-b02, for development and testing.
When running standalone (that comes width JDeveloper) OC4J the Java version is 1.4.2-b28 (client VM)
The problem:
When calling a stored procedure that calls another user defined procedure the returned result is wrong.
The example snippet I've enclosed only success on my standalone OC4J.
When I run the Java-app in JDeveloper using embedded OC4J it behaves incorrectly.
When I run the Java-app deployed at the standalone OC4J that comes with JDeveloper it runs just fine.
When I deploy the Java-app at the Oracle Application Server it behaves bad again.
It looks like the procedure called by the procedure cannot execute correctly or that it got null value as in-parameter.
What puzzles me is that this procedure did work correctly on websphere (JVM 1.2.2 and Oracle jdbc-drivers classes12.jar)
and it does executes just fine on the standalone OC4J.
I have tried different classes12.jar, ojdbc14.jar, different datasources (com.evermind.sql.DriverManagerDataSource,
oracle.jdbc.pool.OracleConnectionCacheImpl) width no succes.

The code follows....
- The java code
CallableStatement cs =
     con.prepareCall("{ call oden.sp_tidGetProjForMember( ?, ?, ?, ?, ? ) }");
cs.registerOutParameter(1, OracleTypes.CURSOR);
cs.setLong(2, employeeNo);
cs.setLong(3, projId);
cs.setLong(4, actId);
cs.setLong(5, period);
cs.execute();
ResultSet rs = (ResultSet) cs.getObject(1);
while (rs.next()) {
     MyItem aItem =
          new MyItem(
               Long.toString(employeeNo),
               rs.getString(1),
               rs.getString(2),
               rs.getString(3),
               rs.getString(4),
               rs.getString(5),
               rs.getString(6),
               rs.getString(7),
               rs.getString(8),     // (Actually a number). This row returns "0" but it shuold return a value greater than "0"
               rs.getString(9));
          items.addElement(aItem);
- The stored procedure:
PROCEDURE sp_tidGetProjForMember (
rs_Proj IN OUT report_types.weakCur -- recordset
,p_pnr IN V_ADMANV.anv_PNR%TYPE -- pnr projektmedlem, NUMBER(12)
,p_projid IN PROJ.PROJ_ID%TYPE -- projekt-id, NUMBER(5), kan vara tomt

Hi Kevin,
Just an addition. To create SSIS package programmatically, please refer to the document:
