Hi Milosz, Thank you for your attention.
This timeout exception occurs only from time to time. For your information, We have configured a distributed transaction in our application server in order to support transaction between Java and .NET clients. WS-AT is the protocol which has been used for managing atomic transactions between distributed applications. Also Oracle DataSource Classname and XADataSource as the resource type are the connection pool configurations in Glassfish. Please let me know if you have any suggestions. Thank you once again.
