Why would anyone want to install a 32-bit JDK on 64-bit Linux? The answer is easy to find if you Google it. Essentially, the 64-bit JDK version for Linux doesn’t support applets and Java Web Start.
Also, Documentum requires the 32-bit version on 64-bit Linux, probably for same reasons in part. When talking about the JDK version 1.5 all the pointers I got were towards using
JPackage in the resolution.
While there were a few pages that outlined the steps, this one appeared to be the cleanest and the one that actually worked for me.
Here are the basics – install the 32-bit JDK and then use
JPackage magic to create some links that are used with
alternatives. This even lets you have multiple JDK’s and choose one of them as default.
