Ant builds for test\orbreinvoke is broken by project re factoring to move some source files to test\regression. I'm preparing some poms for mvn build to get it to work again and will submit a pull request.
I have submitted a pull request including a fix for these builds and updates to the classpath for affected scripts. The scripts for the tao_ns module are tested.
Fixed and merged, thanks Phil https://github.com/JacORB/JacORB/commit/2df5155ca7477d4c5d8d75b530862fd42a8c3d49
