Hello,
we evaluating MyEclipse (v6.5) as our new development tool. Actual we found a problem while creating a EJB project. If we try it some required parameters in .mymetadata are missing. Please add this to the next version of MyEclipseMetadataWriter.write() at line 103 to generate right code: 

       if ( Constants.PROJECT_PACKAGING_EJB.equalsIgnoreCase( packaging ) )
       {
writer.addAttribute( MYECLIPSE_METADATA_PROJECT_J2EE_SPEC, getJeeVersion() ); 
           // TODO : use maven final name
writer.addAttribute( MYECLIPSE_METADATA_PROJECT_ARCHIVE, config.getEclipseProjectName() + ".jar" ); 
       }

Best regards
Marcus Padberg

P.S.
Attached our POM and a modified MyEclipseMetadataWriter which works fine.
