AQServlet gives java.lang.IllegalAccessError

Question

Got this error while running the AQ sample:
java.lang.IllegalAccessError: try to access method oracle.xml.parser.schema.XMLSchema.buildSchemaPathTable()V from class oracle.AQ.xml.AQxmlIdapConverter

I added the following lines to java2.policy and restarted OC4J.
grant codebase "file:${oracle.home}/lib/xschema.jar" {
permission java.security.AllPermission;
Still getting the same error. Tips, ideas ... any?

Hi Rajat,
Here's the info you had requested.
It seems like a compatibility problem between the different libraries. Could you please provide the following information...
1) The Client/server versions of the database. ----------------------------------------------------------------
Oracle9i Enterprise Edition Release 9.2.0.1.0 - Production
PL/SQL Release 9.2.0.1.0 - Production
CORE 9.2.0.1.0 Production
TNS for 32-bit Windows: Version 9.2.0.1.0 - Production
NLSRTL Version 9.2.0.1.0 - Production
2) The version of OC4J. Oracle9iAS (9.0.3.0.0) Containers for J2EE
3) The Created Date and Size of oci.dll. This file should be present in the <Oracle_Home>/bin. oci.dll 112KB 5/1/2002
4) The Created Date and Size of classes12dms.jar. This jar should be present in <j2ee_home>/jdbc/lib. classes12dms.jar 1,169KB 4/26/2002
5) Also, the info about aqxml.jar present in <oc4j_home>/lib.aqxml.jar 455KB 4/28/2002
Pls refer to Install.html accompanied with the sample for info on <j2ee_home> and <oc4j_home>.I went over all the steps and it still gives me the same exception.
Did you encounter this problem when trying to access the IDAP feature?Yes. When I click on the <Send SOAP Message> button.
Do you think this might me have something to do with jazn-data.xml or java2.policy?
Thanks,
Atul
