Method Detail

transactionStart

void transactionStart(Application application,
                      Object transactionData)

Invoked at the beginning of every transaction. The transaction is linked to the context, not the application so if you have multiple applications running in the same context you need to check that the request is associated with the application you are interested in. This can be done looking at the application parameter.

Parameters:

application - the Application object.

transactionData - the Data identifying the transaction.

transactionEnd

void transactionEnd(Application application,
                    Object transactionData)

The transaction is linked to the context, not the application so if you have multiple applications running in the same context you need to check that the request is associated with the application you are interested in.
