I have been looking with Ccleaner what I have installed about Java and I have: Java 2 Runtime Environment, SE v1.4.2_11 Java 2 SDK, SE v.1.4.2_11 Java DB 10.4.1.3 Java(TM) 6 Update 10 Java(TM) SE Development Kit 6 Update 10 Java(TM) SE Development Kit 6 Update 3 Java(TM) SE Development Kit 6 Update 7 ¿Can I savely uninstall any of them? ¿Which one should I have? I think that perhaps there are 2 JVM running though I think this is impossible. View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4188615#...
