No - I am not confusing transaction with state - if a tranasction has been started by a stateless bean or by the container on behalf of the bean (for e.g. TX_REQUIRESNEW), that transaction MUST be completed at the end of the method. The original post was whether stateless beans could use UserTransaction or not and the answer to that was that they could so long as the transaction was started and completed at the end of the method. Please refer to sec 17.3.3 page 341 and 17.6.1 for clarification.
