Thanks for the pointers. For the current installation of JBoss AS (v3.2.7), the JAVA_HOME has been set as an ENVIRONMENT VARIABLE. Hopefully, when I specify it in the run.bat file for the new installation, this value will override the env. variable set globally. I will give it a shot and also try to configure JavaService for the 4.2.1 installation. Thanks again.
