I am using JBossIDE-1.5RC2-Bundle-win32.zip for IDE and jboss-4.0.4RC1.zip for Application Server.

When I am going to create a new EJB3 project using IDE, I am getting the following error:

18:21:42,558 WARN [UDP] packet from /172.19.139.143:3781 has different version (0224) from ours (0227). This may cause problems

Also, IDE is showing a messagebox containing a message that "The selected configuration does not contain the expected EJB3 libraries. Please install JBoss with EJB3 libraries, or try another configuration.

Please let me know the compatible versions.
