Two suggestions. First, do not use JDK 6. There are various incompatibility issues. I recommend that you install the 5.0 JDK first. Also, when you install it, do not install it to Program Files, spaces in directory names give some Java code fits. I have mine installed at c:\apps\jdk1.5.0_11 Second, set the JAVA_HOME environment variable to the location where the 5.0 JDK was installed. I set JAVA_HOME to c:\apps\jdk1.5.0_11 View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4033324#...
