If I didn't take out the configuration #"%JAVA%" -version 2>&1 | findstr /I hotspot > nul if not errorlevel == 1 (set JAVA_OPTS=%JAVA_OPTS% -server)# in run.bat,I only could see the information "system don't find the sepcified file." and JBOSS AS couldn't start when I executed run.bat. When I took out the configuratin above,JBOSS AS started successfully,DOS prompted enviument information and other. I did as you prompted,the message is "java version "1.6.0_03" Java(TM) SE Runtime Environment (build 1.6.0_03-b05) Java HotSpot(TM) Client VM (build 1.6.0_03-b05, mixed mode, sharing)". Thank you.
