Error in deploying entity beans - migration from JBoss to Weblogic 10.3.4

Question

Hi,
I am migrating EJB2.x code from JBoss to Weblogic 10.3.4. As a first step, I am tyring to deploy just Entity beans. I get following error when deploying to server.
'weblogic.application.ModuleException: Exception preparing module: EJBModule(myEJB.jar)
Unable to deploy EJB: CollMetaData from myEJB.jar:
[EJB:011017]Error while reading 'META-INF/weblogic-cmp-rdbms-jar.xml'. The error was:
There are 1 nested errors:

Can someone help me fixing the issue?
I changed schema locations of descriptor files as suggested at http://download.oracle.com/docs/cd/E17904_01/web.1111/e13706/overview.htm#i1074199 (see the third category for '*Enterprise Bean 2.1*' in the listing Table 1-1). Alternatively, you may see the schema locations for EJB2.0 directly at http://download.oracle.com/docs/cd/E17904_01/web.1111/e13719/dd_reference.htm#EJBPG481

JRE version in JBoss is 1.6.0_16. JVM in web logic is pointing to jrockit_160_22_D1.1.1-3 which is come in the package. It doesn't seem to be related to JVM version mismatch.
I think it is an issue with definitions in weblogic-cmp-rdbms-jar.xml file. How should be the definition of entity-descriptor appear for entity bean which has finder methods in ejb-jar.xml?
Please see the snippets from corresponding descriptor files below.
ejb-jar.xml

Please ignore any typos that you may notice in above sample descriptions (because I just typed it here changing original names).
When I try to deploy the application, I get error message as posted in my first post above in this thread. Please correct me if I am making any erros in descriptor files.
