I am migrating all my applications to JBoss 5.1.0GA, but i have a problem with an application that was development with oracle tecnhologies like toplink
When i upload the .ear and startup the server, i have the error java.lang.ClassCastException: oracle.xml.jaxp.JXSAXParserFactory cannot be cast to javax.xml.parsers.SAXParserFactory.
Could us help me?
the best way would be to remove the Oracle XML parser JARs from your app. Hopefully, none of your other Oracle JARs require exactly this one.
I think you could also use Classloader configuration to include your own xml parsers, but I never used this myself.
