I have a problem with error handling. If an exception occurs in the jrnRoute

  • 0

I have a problem with error handling. If an exception occurs in the jrnRoute, it is processed by the exceptionHandler processor. This is OK. But the message which caused the exception still stays in the jrnQueue, is processed again and causes the error over and over again. Also I have a warning (see below) in logs. How to stop the infinite redelivery? I want to throw a message away in case of an error.

Camel configuration

    <camel:onException>
        <camel:exception>java.lang.Exception</camel:exception>
        <camel:redeliveryPolicy disableRedelivery="true" />
        <camel:process ref="exceptionHandler" />
        <camel:rollback markRollbackOnly="true" />
    </camel:onException>

    <camel:route id="translatorRoute">
        <camel:from ref="transactionsQueue" />
        <camel:process ref="messageTranslator" />
        <camel:inOnly ref="apfRequestQueue" />
    </camel:route>
    <camel:route id="jrnRoute">
        <camel:from ref="jrnQueue" />
        <camel:process ref="jrnProcessor" />
        <camel:stop />
    </camel:route>
</camel:camelContext>

    Yes the markRollbackOnly will cause the transaction manager to mark the TX as rollback, and therefore the JMS broker will keep the message in the queue, and redeliver it again. So remove that instead.

    And do as Ben posted above, with handled true:

     <camel:onException>
        <camel:exception>java.lang.Exception</camel:exception>
        <camel:redeliveryPolicy disableRedelivery="true" />
        <camel:handled>
            <camel:constant>true</camel:constant>
        </camel:handled>

        <camel:process ref="exceptionHandler" />
 </camel:onException>
