    Description

      The "transacted" configuration requires a Spring environment. We use JavaEE and we needed to use "transacted". We ported the Spring implementation of the TransactionErrorHandler to JavaEE.

      There is only one major difference: Spring's TransactionErrorHandler derives from org.apache.camel.processor.RedeliveryErrorHandler which brings the behavior that redelivery is done within the transaction. In our implementation there is a RedeliveryErrorHandler which uses the TransactionErrorHandler to force a rollback and create a new transaction for each redelivery.

      Example usage:

      errorHandler(transactionErrorHandler() //
                      .setTransactionPolicy("PROPAGATION_SUPPORTS") //
                      .maximumRedeliveries(5) //
                      .maximumRedeliveryDelay(5000) //
                      .collisionAvoidancePercent(10) //
                      .backOffMultiplier(1.5));
      from("direct:sample") //
                      .transacted("PROPAGATION_REQUIRES_NEW")
                      .to("bean:sampleBean");
