dma_k,
Read the rest of the forum, Eclipse redesigned the API's with the M7 release, This broke Jboss-IDE. The developers are working the issue. A build from CVS actually worked for me. But they haven't release an 'official' milestone release that I know of. If you want to use the JBossIDE version you have. You need to go back to Eclipse 3.1m5a version.
