I'd like to point out that Geronimo does not have anything to do with

Oh well ...

The other useable TMs I know about is the one from JBoss. It embeds 
Tomcat, and you can configure JBoss to have just Tomcat + the TM + the 
DataSource (+ the management stuff) so maybe it can work for you.

This was removed because people complained about bugs which were not 
fixed (since the project is no longer really active). So I'm reluctant 
to add back support. I got in touch with a Tyrex developer a few months 
ago, and suggested they added a standard ObjectFactory in their 
distribution. I don't know if they did it (if they did, great, there's 
no problem anymore).
