The JTA TransactionManager.

getUserTransactionName

public String getUserTransactionName()
Return the JNDI namespace of the JTA UserTransaction for this platform or null; optional operation.

getTransactionIdentifier

public Object getTransactionIdentifier(Transaction transaction)
Determine an identifier for the given transaction appropriate for use in caching/lookup usages.

Generally speaking the transaction itself will be returned here. This method was added specifically for use in WebSphere and other unfriendly JEE containers (although WebSphere is still the only known such brain-dead, sales-driven impl).

Specified by:
getTransactionIdentifier in interface TransactionManagerLookup
Parameters:
transaction - The transaction to be identified.
Returns:
An appropropriate identifier
