[xmlvm-users] xmlvm java.class -> clr/exe

[Juergen S. <jue...@sa...>]

Hi

Is the current (synchronized with SVN today) version of XMLVM able to
cross-compile a Java classfile to .NET byte code?

Basically, xmlvm seems to work fine - when I do (on the usual
HelloWorld.java that does a System.out.println in main):

>> xmlvm --in=HelloWorld.class --target=xmlvm

I get:

[08/26/09 17:48:18.777]    DEBUG: Instantiated:

Looks fine! Cross-compilation to JavaScript also worked. But when I try

>> xmlvm --in=HelloWorld.class --target=clr

I get

Same for 
>> xmlvm --in=HelloWorld.xmlvm --target=clr
or
>> xmlvm --in=HelloWorld.class --target=exe


Am I missing anything or is this not supposed to work?

Best regards, Juergen
