It takes more than a simple JVM stack machine to execute Java..

My Tcl target for XMLVM project which would virtually translate Java to Tcl turned out to be a bigger project than it seemed at the first glance. A simple and straight-forward looking solution was to just implement a stack machine which would simulate a JVM in Tcl. Theoretically that would make it possible to execute JVM bytecodes in Tcl. However, my mentor pointed out that even to execute a HelloWorld Java program class loading and certain fundamental Java classes have to be brought to the target language, which is Tcl in our case.. That definitely is not a very realistic goal for this summer..
