GetCollectionMetaData method is not supported by OracleXMLDataSetGenJDBC

Question

Hi,
We are in the process of migrating our Web Application from Oracle 9i to Oracle 10.1.0.5. Our Web Application runs under WebLogic 9.1 Server and uses Oracle XSQL APIs to store CLOB Data in Database. We are using ojdbc14.jar as well as xsu12.jar and other required Oracle XSQL Libraries.
We observed the following error
===============================
ORA-29532: Java call terminated by uncaught Java exception: oracle.xml.sql.OracleXMLSQLException: Invalid context handle specified. ORA-06512: at XSU.DBMS_XMLQUERY , line 178 ORA-06512: at XSU.XSU$XML_XCHANGE , line 293 ORA-29532: Java call terminated by uncaught Java exception: oracle.xml.sql.OracleXMLSQLException: getCollectionMetaData: this method is not supported by OracleXMLDataSetGenJdbc class. Please use OracleXMLDataSetExtJdbc instead. ORA-06512: at line 1
===============================
When we printed the underlying connection object class name, it appeared as "oracle.jdbc.driver.T4CConnection".
What is the cause of this issue? How to resolve this issue?

One import piece of info: This OracleXMLQuery works against a standard table. The query that fail goes against the following view and uses nested tables(object lists).
SELECT v.name as PACKAGE,
u.name,
u.version,
u.iteration,
u.summary,
u.events_basic,
u.author,
u.rev_date,
u.ext_points,
u.assumptions,
u.preconditions,
u.revision_notes,
u.trigger_event,
u.package as PUID,
u.ALTERNATE_PATHS AS ALTERNATE_PATHS_LIST,
u.EXCEPTION_PATHS AS EXCEPTION_PATHS_LIST,
u.BUSINESS_RULES AS BUSINESS_RULE_LIST
FROM USECASE u, DESIGN_PACKAGE v
WHERE u.package=v.puid
AND EXISTS(SELECT 'X'
     FROM DESIGN_CUR_VER d
     WHERE d.name = u.name
     AND d.version = u.version
     AND d.design_date = u.rev_date)
AND EXISTS (SELECT 'X'
     FROM USECASE_AUDIT a
     WHERE a.package = u.package
     AND a.name = u.name
     AND a.version = u.version
     AND a.timestamp = u.rev_date
     AND a.status_code IN('created','modified','rejected'))
ORDER BY v.name, u.name
