I can't get them work together.

1.) I downloaded and extracted "feature" and "plugins" dir to eclipse directory, but either eclipse does not show it up in plugins list, nor i can find any related entries in wizard to create hibernate xml.
2.) The update site http://download.jboss.org/jbosside/updates/development
keeps an folder "Latest Hibernate Tools" which is NOT showed in eclipse 3.1.2 update site. The plugin.xml says "<?eclipse version="3.0"?>" is that ok?
Seems to me that eclipse 3.1.2 is not supported, but website says "Requirements: Eclipse 3.1 ..." and what about 3.1.2?

Please help, tx a lot.
