I installed Eclipse 3.2M2 and then used the Eclipse Update mechanism to load the JBoss-IDE 1.5M3 for JRE 1.5. After installing the plugins and restarting Eclipse when I check Plugin Details I don't see any for Hibernate or jBPM. I thought these were part of the JBoss-IDE package or is there another update site where I should look for these separately?
In the meantime JBoss IDE 1.5 RC1 was released. But the release was build and tested against Eclipse 3.1.1, so you'll have to stick to this version or maybe Eclipse 3.1.
