Migrating to J2SE 5.0

[Hussein Baghdadi]

Hey all.
I have J2SE 1.4.2 and other Java stuffs like Tomcat, Eclipse, jEdit ......
ofcourse, first I have installed the SDK, then installed other applications.
I want to migrate to J2SE 5.0 , (sure, I will unistall the old SDK).
my question is :
should I uninstall all Java application like Tomcat, and reinstall them after I installed J2SE 5.0
(I will install the new SDK in the same path (and name) of the previous SDK.
any ideas ?
(Sorry, but I didn't find a forum better than this)
thanks.

No, I wouldn't uninstall anything. You'll doubtless have to do a bit of reconfiguring, but to a first approximation, it will just be providing new values for JAVA_HOME in a script here or there.

Actually, I suppose that you won't be changing anything to do with JAVA_HOME, since you're installing the new exactly where the old was.

I haven't tried to do what you're doing, John. I'd vote to go for it, and please let us know if anything breaks.

If you're doing this on Windows, one thing that the SDK does (that you might not have noticed if you weren't paying close attention) is to also install a JRE in the "Program Files" directory - not the JRE that is part of the SDK, but a separate JRE that I think gets used by browser plug-ins.

On my computer, the J2SDK 1.4 installation stuck it in "F:\Program Files\Java\j2re1.4.2_05" while the 1.5 installation stuck it in "F:\Program Files\Java\jre1.5.0". I doubt any of your development tools would be using this JRE.

best keep the 1.4 around for now. Quite a few things don't work against 5.0 yet (Orion appserver is an example, I'm sure it's not the only one).
