#311 J2EETransactionFactory unoptimally retrieves UserTransaction

[Miro Halas]

Code in class J2EETransactionFactoryImpl, emthod
requestTransaction iterates through all JNDI names even
though the JNDI name for a given J2EE server is known
ahead. This should be possible to optimize to use the
most likely JNDI name for a given server.

This also applies to getTransactionManager when retrieving
for TransactionManager.
