                               org.apache.camel.Processor onExceptionOccurredProcessor)

Creates the transaction error handler.

Parameters:

camelContext - the camel context

output - outer processor that should use this default error handler

logger - logger to use for logging failures and redelivery attempts

redeliveryProcessor - an optional processor to run before redelivery attempt

redeliveryPolicy - policy for redelivery

exceptionPolicyStrategy - strategy for onException handling

transactionTemplate - the transaction template

retryWhile - retry while

executorService - the ScheduledExecutorService to be used for redelivery thread pool. Can be null.

rollbackLoggingLevel - logging level to use for logging transaction rollback occurred

onExceptionOccurredProcessor - a custom Processor to process the Exchange just after an exception was thrown.

This implementation will invoke ensure this occurs synchronously, that means if the async routing engine did kick in, then this implementation will wait for the task to complete before it continues.

Parameters:

exchange - the exchange
