getTransactionIdentifier

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).

transaction - The transaction to be identified.

Returns:

An appropropriate identifier
