Title: Begin a Transaction

The sub-chapter with title "Distributed Transactions" should not be under this chapter. Move it somewhere else.

The text is more or less ok. I mean distributed transaction description:
A distributed transaction is one where the transaction participants are in separate applications on multiple servers. If a participant joins a transaction that already exists, rather than creating a new transaction context, the two (or more) participants which share the context are participating a distributed transaction. In order to use distribured transactions, you must configure the ORB. Refer to Refer to the ORB Configuration section of the Administration and Configuration Guide for more information on ORB configuration.
but it's not mentioned that there should be possible to use JTA distributed transactions (described in chapter about transactions above) as possibility with some limitations.
