I looked at jinterface (never used it), and it seems like it would be
possible to write a generic tool that would expose any Java api to
Erlang via rpc using jinterface behind the scenes. It would be used by
starting up a JVM as in

java -jar erljava.jar -name jvm1 -input foo.jar

if foo.jar had a class such as

package mypkg;

class Foo {
 public static String echo(String arg) { return arg; }
}

Erlang could invoke using a call such as

Str = call(jvm1, mypkg_foo, func, ["echo this"]).

Handling non-static functions is a bit harder as it would require
setting up remote stubs for remote objects.

I hope I'm not totally off track here :)
