So if I have to choose between BAFramework and JBoss TS, you recommend me the first one? Seeing the documentation seems easier with BAFramework and more transparent than JBoss TS.

The BA Framework was written by a Masters student working for JBoss. It is designed to make it easier to use Business Agreement Transactions. There is nothing in the _definition_ of the framework which ties it to JBossTS/XTS but the _implementation_ we provide relies upon the JBoss XTS APIs which in turn rely on JBossTS. So, any program using it needs to be deployed with both JBossTS and the JBoss XTS.

So, the answer is, you should use both.

By the way, the current implementation of the BA Framework was based on the version of JBossTS/XTS included in JBossAS 4.3.*. It relies upon implementations of the 1.0 WS-C, WS-TX and WS-BA standards. The new JBossAS 5.0.CR0/1 includes both the old 1.0 XTS and a new implementation based on the 1.1 standards. The BA Framework implementation needs a few small tweaks to make it to work with the new 1.1 implementation (it needs to include API classes from the 1.1 packages). It should still work with AS 5.0 using XTS 1.0. If you try it with AS 5.0 let us know what happens.
