        Hi!

1) about:plugins shows gcjwebplugin correctly. I have a symlink in
~/.mozilla/plugins:

lrwxrwxrwx 1 fraga users 53 Oct  7 11:25 libgcjwebplugin.so
-> /usr/local/classpath/lib/classpath/libgcjwebplugin.so*

2) gappletviewer 

address@hidden /usr/local/classpath/bin$ ./gappletviewer 
WARNING: CURRENTLY GAPPLETVIEWER RUNS WITH NOSECURITY MANAGER.

[press 'c' or 'C' to continue or anything else to quit]
c
appletviewer: no input files

3) firefox -g ( I think it won't help)

        ***

        The previous maintainer (Michael Koch) answered my e-mail
confirming that he can reproduce that on his system too but didn't
offered a solution.

        Any hints?
