Java and JavaScript in the Database

I tried to load jaxrpc.jar, saaj.jar, axis.jar, etc., all of which came from Apache Axis 1.3 package. First I tried to load jaxrpc.jar and got many errors. For example:

errors : class javax/xml/namespace/QName
ORA-29545: badly formed class:

This is just one of the error message (many of them appeared).

The class is actually in the jaxrpc.jar file, and surprisingly, in CREATE$JAVA$LOB$TABLE table, I saw this classes was loaded. So I don't know the loading was succesful or not.

From the above error message, seems that compiler version may not match: my Oracle is 9.2 which I believe has JDK 1.3, but Axis 1.3 is for JDK 1.4. So that's why it said "badly formed class" ? And why the class was still loaded into table?

Any advices will be very appreciated

Thanks
