I changed the way the TyrexResourceFactory works (new code will be in 4.0.3
b1), so your patch is no longer needed. Note that you should have been able
to use it by specifying the resourceFactory.

I am aware of the securiy check issue (but can't do much about it).

Also, to use the transaction manager, you need to get the OTS classes.
