JIntegra. It implements DCOM in java. That's not free, so it's either
that, or you wrap it yourself, using JACE and C++ for instance.

You probably won't need to wrap the ejb as a web service. COM supports
callbacks (Event Sinks) but COM+ doesn't(if you mean COM+ == MTS). Which
reminds me, if both components are transactional, if you do this or the
JIntegra thing, you'll probably will be spawning 2 separate
transactions, so be careful.

Very good point. Web services offer flexibility. You'll need to export
your COM+ objects as web services, using the SOAP Toolkit for Visual
Studio 6.0. And run IIS.
