Re: Re: Re: Re: classloader issue with xercesImpl

Thank you very much Guillaume and Florent : The suggested configuration below works well when adding
org.apache.xerces; \
org.apache.xerces.parsers; \
to the org.osgi.framework.system.packages entry in my own felix-config.properties file.

However, this seems to be a non-standard customization, so I suppose that applications should not use Xerces nowadays.
Could you tell me in a few words what I should suggest to the project for their xml config file management in Jonas 5.1 / jdk6?

Regards,
Bernard

The schema available at http://jonas.ow2.org/JONAS_5_1_6/doc/doc-en/html/j2eeprogrammerguide.html#classloader.tools do not speak about lib/endorsed directories. How does this "exported package" functionnality operates with the existing "filtering classloader" option ?
