TXMBeaanStats sample script is using wrong keys and invalid method name

The sample script for counting TX events is using inconsistent keys in the counting rules and in the key set return rule. All keys entered into the keyset are labelled using a String of the form "TX XXX" while the corresponding counter rules use a key of the form "TX XXX request". Also, each insertion of key "TX Rollback" in the key set return rule is duplicated unnecessarily.

The script also tries to track Transaction begin operations by injecting code into a non-existent method Transaction.begin(). Of course, begin operations are implemented by creating instances of the class implementing Transaction, not by calling a begin method defined by this interface. Unfortunately, we cannot fix this by injecting code into either UserTransaction.begin or TransactionManager.begin as the clsses which implement each respective interface inherit their bein method from a common parent which implements neither interface. Fixing this will require the use of a JBoss AS specific rule.
