Thanks for your help here Jos, 
now things are really starting to make sense. I will be patching up my

Can you tell me what this second parameter does?

Ahh, now it all makes sense to me. I was missing these files,
and used the ECMA stack.

Just use the same as in the ECMA:

Ohh, another missing file. Ok i need to get a full list of files...

no, all that is there.

that is fine, i thought you were using the standard stack.

Ok, i have ran all the test, only two pass on the current
implementatation, that is amazing since i dont even have all the code

Ahh, well we should talk to the dotgnu guys about java and

also about webservices, they are working on some right now.
