embedding other languages

I have a question, I want to start a project that allows Tcl code be used. So, basically, I need to embed the Tcl interpreter into my java code. I know there is the Java Tcl projects out there. But they don't fit my need.
Any help would be appreciated.

My advice would be look into the already existing TCL JAVA wrappers (since I am sure they are open source) and use the work they have already done and make it "fit your needs"
No point in reinventing the wheel.
