Stored Procedure Call with Connection Pools

Question

Hi everybody,
I have changed my Database-Connection to Connection Pooling.
No I try to call a stored procedure like this:
Connection connection;
CallableStatement callStmt;
Integer sp_result;
//--- Set callable stored procedure
String call = "{?=call myStoredProcedure(?,?,?)}";
try {
if( connection != null ) {
callStmt = connection.prepareCall( call );
callStmt.registerOutParameter( 1, java.sql.Types.INTEGER );
callStmt.setInt( 2, 3 );
callStmt.setString( 3, plz );
callStmt.setString( 4, ort );
callStmt.execute( call );
sp_result = new Integer( callStmt.getInt(1) );
callStmt.close();
result = sp_result.intValue();
} else {
log.error( "Connection = null" );
} catch( SQLException ex ) {
log.error( ex.toString() );
ServletUtils.forwardRequest(this, request, response,
"/error.jsp", "errorMsg", ex.toString() );
Without Connection Pooling, my Connection is of
'weblogic.jdbc.mssqlserver4.MicrosoftConnection'
With Connection Pooling my Connection is of
'weblogic.jdbc2.rmi.SerialConnection'
And now, the stored procedure can't be found anymore.
There comes an SQLException:
Gespeicherte Prozedur 'myStoredProcedure' konnte nicht gefunden werden.
Severity 16, State 62, Procedure 'myDBServer null', Line 5
One possibility is that the SerialConnection can't call the stored procedure
like the Microsoft-specific Connection (I use MS-SQL-Server)
Another is that the call have to be another stucture.
I would be pleased if somebody is expirienced in this behaviour.
Thousand thanx,
Hammer.

You need to use a DataModifyQuery as your query does not return anything.
