What you have described is an XA transaction. This allows a transaction to scope across multiple layers i.e. JMS provider, DB or any other EIS. Most containers can be configured to use both non XA and none XA transaction so check your container settings!

For example if you are using JMS with XA transactions the following is possible.

Start Transaction
      |
   DB Insert
      |
   Send JMS Msg
      |
   More DB Inserts
      | 
   Commit Transaction  <- Only at this point will the database records be inserted and the JMS message sent.

XA Tranactions are only available in full Java EE containers so XA transactions are not available in Tomcat.

Good luck!
