                     throws Exception

This method calls the next interceptor in the chain.

All Throwables are caught and divided into two groups: application exceptions and system exceptions. Application exception are simply rethrown. System exceptions result in the transaction being marked for rollback only. If the transaction was not started by the container (i.e., it was inherited from the client) the system exception is wrapped in a TransactionRolledBack[Local]Exception.

Parameters:

invocation - The Invocation of this call.

inheritedTx - If true the transaction has just been started in this interceptor.

Throws:

Exception - if an exception occures in the interceptor chain. The actual exception throw is governed by the rules in the EJB 2.0 specification section 18.3
