User development, A new message was posted in the thread "uninstall before update ?": http://community.jboss.org/message/532910#532910 Author : Denis Golovin Profile : http://community.jboss.org/people/dgolovin Message: -------------------------------------------------------------- You cannot use update to install JBoss Tools 3 over previous JBoss Tools 2 for several reason. 1. JBoss Tools 3 is for Eclipse 3.5 Galileo and cannot be installed on Eclipse 3.4 Ganymede 2. You cannot do that in two steps update Eclipse 3.4 to Eclipse 3.5 and then update JBoss Tools 2 to 3, because Eclipse doesn't support updates between major releases like 3.4 to 3.5.   So the only way for you do it from scratch and install it by following this manual http://www.jboss.org/tools/download/installation/update_3_1.html. I personally use JEE bundle, because it easier to do reinstall in this configuration. -------------------------------------------------------------- To reply to this message visit the message page: http://community.jboss.org/message/532910#532910
