XMLBEANS classcastexception issues when migrating from WLS 8.1 to WLS 9.2

Question

Hi
We are migrating our applications from Weblogic 8.1 / xbean (?) to Weblogic 9.2 / apache xbean 2.2.9-r540734 .
We compiled our schema successfully with new version after making changes recommended by bea (replaced all com.bea.xml occurrences to org.apache.xmlbeans ) along with ant task def etc.
XBEAN Compilation produces classes in following package structure: com.tuftshealth.container.providerListService.* and com.tuftshealth.container.providerListService.impl.*
Our XSD looks like below:
===============================
<?xml version="1.0" encoding="UTF-8"?>
<schema xmlns="http://www.w3.org/2001/XMLSchema" xmlns:this="http://www.tuftshealth.com/Container/ProviderListService" xmlns:messageheader="http://www.tuftshealth.com/Base/MessageHeader" xmlns:name="http://www.tuftshealth.com/Base/Name" xmlns:status="http://www.tuftshealth.com/Base/Status" xmlns:network="http://www.tuftshealth.com/Base/Network" xmlns:date="http://www.tuftshealth.com/Base/DateRange" xmlns:contact="http://www.tuftshealth.com/Base/Contact" xmlns:address="http://www.tuftshealth.com/Base/Address" xmlns:reference="http://www.tuftshealth.com/Base/Reference" xmlns:member="http://www.tuftshealth.com/Base/Member" xmlns:benefit="http://www.tuftshealth.com/Base/Benefit" xmlns:covlimit="http://www.tuftshealth.com/Base/CoverageLimitations" xmlns:groupriders="http://www.tuftshealth.com/Base/GroupRiders" xmlns:buslninfo="http://www.tuftshealth.com/Base/BusinessLineInfo" xmlns:phone="http://www.tuftshealth.com/Base/Phone" targetNamespace="http://www.tuftshealth.com/Container/ProviderListService" elementFormDefault="qualified">
     <import namespace="http://www.tuftshealth.com/Base/MessageHeader" schemaLocation="../Base/MessageHeader.xsd"/>
     <element name="ProviderListRequest" type="this:PrivderListServiceRequestType"/>
     <complexType name="PrivderListServiceRequestType">
          <sequence>
               <element name="MessageHeader" type="messageheader:MessageHeaderType"/>
               <element name="providerRequestInfo" type="this:ProviderListRequestParamsType"/>
=================================
This results in exceptions at run time when we call a Tibco using a generic broker class.
The broker uses following method to return class to us:
obj = XmlObjectBase.Factory.parse(XMLString);
XMLString contains following payload:
<?xml version="1.0" encoding="UTF-8"?>
<ns0:ProviderListResponse xmlns:ns0="http://www.tuftshealth.com/Container/ProviderListService">
Debug Info:
PACKAGE NAME: **** com.tuftshealth.www.container.providerlistservice.impl
CLASS NAME: ****** com.tuftshealth.www.container.providerlistservice.impl.ProviderListResponseDocumentImpl
java.lang.ClassCastException: com.tuftshealth.www.container.providerlistservice.impl.ProviderListResponseDocumentImpl
XmlObjectBase is returning the class with www in package name. This causes ClassCastException.
We tried to use XmlObject and XmlOptions is various combinations to see if "www" in package name goes away but it stays the same.
Can someone please help us here ? It seems that behavior of XmlObject or XmlObjectBase has changed between two versions. Our apps can't work without the broker to return correct class type.
Thanks for your help,
Shikhar

Hi,
You can get rid of JSP version specific problems by using the following weblogic.xml file:-
<weblogic-web-app>
<jsp-descriptor>
<jsp-param>
<param-name>backwardCompatible</param-name>
<param-value>true</param-value>
</jsp-param>
</jsp-descriptor>
<weblogic-web-app>
It will also confirm if the error you are seeing is due to JSP version differences in 8.1 and 9.x.
Regards.
