public class WriteLockException
extends java.lang.RuntimeException

Indicates that the TransactionProvider cannot create a write Transaction at this time. This exception occurs, for example, in an application that has a Source produced by a Template. The Source is active in a parent Transaction and the application has begun two child Transaction objects. If the application changes the state of the Template in one child Transaction and then attempts to change the state of the Template in the other child without having first prepared and committed the first child Transaction into the parent Transaction, then the TransactionProvider produces this exception.
