Re: [openorb-users] Using OpenORB with NSIcom CrE-ME VM for PDA's

[Wouter W. <wo...@xs...>]

There's no real possibility of debugging it on the creme JVM :(
And I know CrEme can find the openorb jar files, cause if I move them, I get 
a classdefnotfound error.

I e-mailed NSIcom about it as well,
this error leaves me kinda clueless.
If only I knew why it can't instantiate the ORB implementation.
