Problems with Weblogic 8.1 SP3 and Toplink 10.1.3

Question

Hi!
I'm runnning into two problems when using toplink 10.1.3 and weblogic 8.1 SP3.
I mapped my classes with the mapping workbench, where I defined also the optimistic locking properties.
When I export that project for bean compiling there are entries like store-version-in-cache.
When i compile the beans i get an exception that store-version-in-cache is a unexpected element.
Ok, next problem: i leave out the locking properties, beans are compiling.
When i start the server and call a named query i get the following exception:
[TopLink Warning]: 2004.11.12 05:25:13.437--ServerSession(697447)--java.lang.AbstractMethodError: weblogic.jdbc.wrapper.
Statement_COM_ibm_db2_jdbc_app_DB2Statement.setFetchSize(I)V
I think I configured the server correctly (but of course i'm not absolutly sure). Where is the fault?
Any help? Thanx.
Greetings volker

Not sure on the first problem, store-version-in-cache is a valid element. Make sure you are using the same version of the Mapping Workbench and the runtime library. Please attach the XML for the version locking policy that was generated and the error message.
The abstract method error seems to indicate that the setFetchSize method is missing on your driver.
setFetchSize has been part of JDBC and JDK since JDBC 2.0/JDK 1.2, how old is the driver that you are trying to use? I noticed the COM is uppercase, so I assume this is a very old driver, can you use the more update version? TopLink requires JDK 1.3 support as a minimum.
