Is this how the plugin works > in Netscape and other programs ? Yes. Its also the method for doing things like embedding Java into PHP. This isn't really much different conceptually from embedding a Perl interpreter, but it does mean that the program needs to play nice with the JVM. > Uh, you can't really call the normal IO functions, read()/write(), etc... > without it piping through the thread system in some way.

I think we need more information, e.g. does the program also attempt to use pthreads or the like? -- Greg Lewis Email : glewis@eyesbeyond.com Eyes Beyond Web : http://www.eyesbeyond.com Information Technology To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-java" in the body of the message
