it seems eclipse.exe couldn't find java.exe. You can either renistall JRE or add it path to java.exe in <eclipse-home>/eclipse.ini file as -vm c:/path-to-java-home/bin/java.exeso your eclipse ini file could look like this: -vm c:/path-to-java-home/bin/java.exe | -debug | -showsplash | org.eclipse.platform | -vmargs | -Xms512M | -Xmx1024M | -XX:PermSize=256M | -XX:MaxPermSize=256M View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4163002#...
