Javassist, j2ee 1.3, eclipse

[danydyn]

Hi,
I am developing a EJB project for weblogic 8.1 server, in eclipse, using hibernate for persistence.
My project has a j2ee 1.3 facet, since this is the version weblogic 8.1 requires.

Hibernate requires to put the javassist 3.4 jar in the project's classpath, but when I do it I get an error from eclipse: Facet version for Enterprise Application project MyProject must be 5.0 to contain Java EE 5.0 project lib javassist-3.4.GA.jar.

Any ideas?

After removing the manifest file from the jar, eclipse finally puts it in the classpath.
I inquired, and it seems that only when the Manifest-version:1.1 and Specification-version:3.4 lines in the manifest file are deleted, eclipse agrees to accept the jar.

Why is that?
