I believe integrating JOTM will require a lot of discussion with the
JOTM guys, and so far I haven't managed to corner them in person at
conferences.
I haven't looked at JOTM in quite a while but doubt this aspect has
changed much.
The basic problem is that there is no defined interface between the
transaction manager and the connector module. Something has to keep
track of which managed connections are associated with which
transactions. We do this primarily in the connector module whereas
IIUC JOTM does this right in JOTM. I think this is kind of an
architectural mistake, but haven't had a chance to get together and
discuss it in detail.
I'll certainly be free with my opinions if anyone wants to look into
this further :-)
