I got tomcat and java working by installing via YUM. But then I wanted to use a different version of JAVA (no idea why). So I messed with the Alternatives. and I guess I added some bad comments in that attempt. now even if I uninstall java and tomcat, then re install. I cannot get it to run. Error Code 4 or cannot find java. anyone know where to find the RAW alternates file or get around this issue?
