I coded a Java program that I would like to convert to web. I want to use PHP to create instances of my Java classes. I know of a couple ways of doing this but here's the problem: I'm doing this on my shared hosting account without command line access, so I cannot install any extensions or plugins or anything of that sort. Any solutions out there?

Forgive me if i'm wrong, but can't some browsers now embed Java Apps?

yes they can.

hy dont you just write it PHP??...

No, not really...
I've heard that was an PHP - Java bridge for php4, but that it was not that much used, and abandoned.
I don't think it exists with php5...

I approve Dans here, you will have it running faster if you rewrite it to PHP.
Especially with the php loose constraints when compared to java.

I know i come out with useful things sometimes :P
