My application (Eclipse RAP 1.4 or 1.5, EclipseLink ORM, PostgreSQL) runs fine in my IDE or in a Eclipse OSGI server (just the binary without GUI). The second one only works if the application is unpacked (jar-Archive does not work).

For a deployment on a Tomcat7-Server I had to pack the plugin into a WAR-file (using the plugin from the incubation update site). It starts well but as soon as the EntityManager is instanciated (meaning the persistence.xml is accessed by EclipseLink), I get this error:

I tried to change parts of my XML but that doesnot seem to help. I debugged deeply into the EclipseLink library and the SAXParser parsing the config file and found that the MalformedURLException seems to be through because of a missing System-ID or encoding.

Is my general setup wrong? Maybe the Parser is not able to read from the jar-File in this context..
Any help is appreciated...

Please include your persistence.xml and the structure of your war file.

the persistence.xml is located in the file "WEB-INF\plugins\myplugin_1.0.0.201205011529.jar".
I tried putting it directly into the WAR or in an META-INF subdir but that didnt help either...

(note: the blanks after the "jdbc:postgresql:" and "http:" substrings are intentional to avoid URL-Formatting and are not in the actual files)

Normal servlets only put lib on the classpath, so your issue has to do with your OSGi usage from org.eclipse.equinox.servletbridge_1.2.100.v20120209-2014.jar. All of the plugins are not on the normal applications classpath, so JPA cannot see them.

I'm no OSGi expert, but my guess is you need to at least set the class loader for EclipseLink to use, using the "eclipselink.classloader" persistence unit property.

Refer the EclipseLink's OSGi examples,
http://wiki.eclipse.org/EclipseLink/Examples/OSGi

Thank you, but setting the "eclipselink.classloader" property didnot help.

I will try and deploy the persistence packages as bundles.

Slitely unrelated question (as I am not that familiar with deploying servlets etc):
would this be a problem if I would use the Virgo application server?

Ok, I tried and deploy the WAR on a Glassfish server: same result! Both 32bit Windows and 64bit CentOs...
What am I missing?
