Java has nothing to do with javascript. I guess you are really asking
about javascript so let's forget about java.

Having a full python runtime in a browser would be a really bad idea
because imagine a website telling your browser to "import os ;
os.unlink( 'your_secret_very_important_file' )". If you want to write
your browser client code nevertheless in python you can use pypy [1]
to translate it into javascript. This is also what I do and it works
pretty well in conjunction with MochiKit [2].

HTH,
