 From what I understand, in the Java world there are XA (distributed  
transaction) resources and XA managers. Many kind of libraries are XA  
resources, including JackRabbit, which mean that they register  
themselves with a XA manager if one is present.

Then all transaction begin/commit/abort goes through the manager,  
which itself redispatches it to all registered resources, and does  
commit using two-phase commit.

What I don't know is how to instanciate a XA manager, and make sure  
JackRabbit uses it.
