Hi all,
I have tried implementing singleton servcie in MDB,but dint work as expected..Without MDB , implementation of Singleton service is wokring fine..but wanted to achieve transactionality..
More detail:
1. Singleton servcie will picked up the message from foriegn jms queue using onMessage().
2. It will send the message to some other service (like proxy service).
3. If some error occurs ,it should rollback the entire transaction as well as put the message to original queue..
4. Rollbacked message will get again picked up by singleton service without loosing sequencing.
In short, Message wont get loss until successful delivery.
Please suggest some few approach to achieve rollback operation...
Thanks,
Neelam.
