Not sure why you want to run Galileo version of JBoss Tools - why not use the JBoss Developer Studio 5 version you found ?
Beyond that I have a hard time understanding what you otherwise are asking for. what MVC implementation are you referring to ?
i use jboss developer studio 5 vversion beta 1 32 bits on windows 2008 and 64bits on redhat 6.0.
1/ yes i search how to MVC implémentation with Mysql community ...under windows and redhat
