If you want to get the Java plugin working again for the recent version of Mozilla (and so Galeon, Epiphany, etc.), the easiest way ist to download and install this package. (link updated 2003-07-15. See comments for details. Thanks to Google there is much traffic on this node.)
The problem is that Mozilla is already compiled using gcc-3.2 and the plugins from Blackdown seem to be gcc-2.95 versions. Of course you can download an unpackaged version from Sun yourself and maybe build your own .deb, but since this is exactly what the creator of the above mentioned package did you can save your time unless you don't want to install binaries from untrusted sources (but then, why would you trust Sun?).

Broken link
The server doesn't has the package anymore. Anyone has another url for the package?
Updated link
The package has changed it's revision. This is the actual link, but there is now a complete apt repository for this and other packages. Insert this lines into your
/etc/apt/sources.list:deb http://jopa.studentenweb.org/debian ./
deb-src http://jopa.studentenweb.org/debian ./
See this link for a brief description.
