Assuming, your jdk is installed at C:\Programmi\Java\jdk1.5.0_12, you can edit the run.bat file present in %JBOSS_HOME%/bin folder to add the following entry at the start: set JAVA_HOME=C:\Programmi\Java\jdk1.5.0_12 The other way to do this is, set an environment variable JAVA_HOME in Windows and point it to C:\Programmi\Java\jdk1.5.0_12 View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4081255#...
