How to install Hibernate Tools in Indigo

from: http://planet.jboss.org/view/post.seam?post=jboss_tools_milestone_for_eclipse_3_7_m6_indigo

Installation

Read this very carefully - if you don't follow this you *will* have problems running this milestone since Eclipse 3.7 M7 is not compatible with Eclipse 3.7 M6.

1. Download & Install Eclipse 3.7 M6a (Indigo) JEE bundle.
2. Run and add this URL to Eclipse's list of available update sites:

   http://download.jboss.org/jbosstools/updates/development/indigo

3. Disable all other URL's except that URL and this
   

   http://download.jboss.org/jbosstools/updates/indigo/M6/

4. Now go and install the JBoss Tools components you want from the JBoss Tools updatesite

Step #3 is the important one - this prevents P2 from overriding your M6 installation with M7 updates.
