I downloaded eclipse ganymede 3.4.2 and I tried to instal Jboss tools from update site porvidet from your site http://download.jboss.org/jbosstools/updates/stable/

I tried to instal only the firs chackbox so the Jbos Tools 3.0.3v200910211631N-H194-GA and left the second chackbox Jboss Tools Integration unchecked

When the instalation hits about 50% the folowing error arises :

An error occurred while collecting items to be installed
