I have gotten a vps with plesk 8.1 installed on it. And I noticed that the tomcat plugin for it is a tomcat 5.0 setup, which is fine. However it only runs jdk 1.4.2. My question is, if I were to install jdk 1.5.x onto the linux machine, would that break anything in plesk? Does anything it does use the jdk that is installed, that it couldn't do with 1.5? I would be installing it along side 1.4, and not overwriting it, so that shouldn't be a problem, and I just won't change the java_home environment variable. and then just setup the tomcat.conf files to point to the location of the jdk 1.5. But does anyone know of any reasons why this wouldn't work? Or have any trouble experiences they want to share about doing this? Thanks for the help.
