The JTA API

The JTA API is made up of the two interfaces and one exception that are part of the java.transaction.xa package. Derby fully implements this API.

• Recovered global transactions
  Using the XAResource.prepare call causes a global transaction to enter a prepared state, which allows it to be persistent.
• XAConnections, user names and passwords
  The behavior of transactions created by XAConnection objects varies according to whether a user name and password are specified when the XAConnection object is created.
• XA transactions and deferred constraints
  Derby defines how some XAResource methods behave in conjunction with deferred constraints.
