You are trying to run with a JRE, you need to set JAVA_HOME to where you installed a JDK. Either that or edit the run.bat file to remove the check for the 'server' JVM - to do that, comment out these lines: "%JAVA%" -server -version 2>&1 | findstr /I hotspot > nul | if not errorlevel == 1 ( | set "JAVA_OPTS=%JAVA_OPTS% -server" | ) View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4266405#...
