Weblogic jpa and oracle xmltype column type

Question

Hi,
i try to use jpa with a table with a column of "xmltype"
i use weblogic 10.3.2.0(eclipselink) and i got this error :
java.lang.NoClassDefFoundError: oracle/xdb/XMLType
Of course the xdb.jar and the xmlparverV2.jar are bundled in the ear with the others library,
and i also put them in the lib directory of the weblogic server.
In my persistence class the filed is declared as a "String".
I try also to use a DescriptorCustomizer with a DirectToXMLTypeMapping
to access to the value of the field as a string.
Thank you for your help.

Option-1). If you want the classes to be loaded from inside your Application only then you can use ClassLoader filtering ...
That will be a best option ....Just put your Xdb.jar file inside your applications Lib directory and apply classloader filtering. Like this you need not to edit the Server Classpath....so other applications will not be forced to use the Jar which u want for a specific application.
Classloader filtering example demonstrated here: http://weblogic-wonders.com/weblogic/parsers_issues/

Option-2). add the path of this Jar in *"setDomainEnv.cmd"* (This script is present in <DOMAIN_HOME>\bin directory) in the POST_CLASSPATH variable...
set POST_CLASSPATH=D:\oracle\Middleware\user_projects\domains\base_domain\config\lib\oracle.xdb_11.1.0.jar;
