Unfortunately, Palm no longer has the Java files available for download.
See

If you happen to get hold of them, upload the .prc files to a website, navigate to it from the Web browser. Click on each file and it will install.
If I still have them, I'll post back here, but I believe I deleted it.
Opera works well. A little slow, but I use it whenever the regular browser doesn't work. ie. there's no mobile version for the site.
