Port Java to C/C++ or java to .dll?

I've built a java app part of which I want to make available to C/C++ programs as an API.

I see two possibilities:

1. Rewrite the whole program (about 80 000 lines..... :-(

Are there any tools out there to support that?

Tools to map java-classes to C/C++ libraries to make that port easier?

2.Bundle the jar with a jre and turn it into a dll. Is that possible?

Any other suggestions?

Grateful for any help!
