I repeat: you need JDK 1.5 to compile 4.2.2. http://java.sun.com/javase/downloads/index_jdk5.jsp, download JDK 5.0 Update 15 Why are you compiling the source? Why not just download the binary? With the binary, installation is simple: 1) Download binary zip file to your hard drive 2) Unzip the zip file 3) In the bin directory: chmod a+x *.sh 4) Make sure JAVA_HOME is set to the JDK 5 directory Then to run it: 5) cd bin 6) ./run.sh 7) Open browser at http://localhost:8080 View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4140584#...
