If you have the Enterprise edition of either XMLSpy 2006 or MapForce 2006, you'll be excited to know that the latest release (R3) now supports integration with Eclipse.

I've always liked XMLSpy, yet I've hated having to launch a separate editor outside of Eclipse. With R3, this is no longer a problem (same goes for mapping in MapForce 2006).

You can download the integration installers from the Altova website

I really wish all tools vendors would build on teh Eclipse platform. It would make life a whole lot easier.
