Q&A
| Q1: | How is a local transaction different from a distributed transaction? |
| A1: | A local transaction manages only a single resource manager, such as a database or a JMS provider. This is managed by setting methods of the JDBC Connection object or the JMS Session object. On the other hand, a distributed transaction is a global in a sense, and is used to access multiple resource managers. JTA is used to coordinate and manage both local and distributed transaction through the UserTransaction interface. |
| Q2: | What are the main resource managers used in a J2EE distributed transaction? |
| A2: | Three types of resource-managers can participate in a J2EE distributed transaction: JDBC, JMS, and JCA resource managers. |
