Please refer to attached flow diagram.

As per high level flow diagram, my webservice 1 perform three tasks in one JTA transaction.

1.DML operation on database 1
2.DML operation on database 2
3.In the end, Web service 2 invocation.

If there is a transaction timeout while I'm still in middle of service 2 call, can I commit the two database calls (1 & 2) provided no errors received while executing the queries?

Regards,

The purpose of transactions is handling multiple operations on different resources as if they were a single atomic unit of work. If you want first two calls to be handled separately from the third call to the webservice, you need to have two different jta transactions.
