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? View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4227581#... Reply to the post : http://www.jboss.org/index.html?module=bb&op=posting&mode=reply&a...
