Subject [jira] Created: (CAMEL-2384) Getting header value in pojo using @Header annotation
Date Wed, 20 Jan 2010 19:29:46 GMT
Getting header value in pojo using @Header annotation 
------------------------------------------------------

                 Key: CAMEL-2384
                 URL: https://issues.apache.org/activemq/browse/CAMEL-2384
             Project: Apache Camel
          Issue Type: Bug
          Components: camel-core
    Affects Versions: 2.1.0
         Environment: Windows xp, jdk 1.6
            Reporter: preben


Header value (and body) is not bound in pojo method:
Route definiton:
                camel:route trace="true" id="RapNotificationRoute">
                        <camel:from  uri="oracleQueue:queue:FURTHERELEMENTS_TEST?jmsMessageType=Text"/>
                        <camel:transacted ref="PROPAGATION_REQUIRED"/>
                        <camel:wireTap uri="seda:audit"/>
                        <camel:to uri="mock:result"/>
                </camel:route>

                <camel:route id="AuditRoute">
                        <camel:from uri="seda:audit"/>
                        <camel:bean ref="auditMessageDAO" method="audit"/>
                </camel:route>

auditMessageDAO interface:
      public void audit(@Body String body, @Header(value="JMSMessageID" String jmsMessageId)

Trace from log when running: 
[Camel thread 0: seda://audit] 20 jan. 2010 - 12:22:09,858 INFO org.apache.camel.processor.interceptor.Tracer
[42a5443b-0a62-4477-885f-c6f6c40274b1 >>> (AuditRoute) from(seda://audit) -->
ref:auditMessageDAO method: audit <<< Pattern:InOnly, Headers:{JMSDestination=PLAYLISTE.FURTHERELEMENTS_TEST,
JMS_OracleDelay=0, JMSDeliveryMode=2, JMSRedelivered=true, JMS_OracleTimestamp=1263986526156,
JMSType=null, JMSCorrelationID=null, JMSXRecvTimestamp=1263986529858, JMSXState=0, JMSXDeliveryCount=2,
JMSMessageID=ID:7D97CBE346B7CAA2E040650A0A103AC2, JMSTimestamp=1263986526156, JMSPriority=1,
JMSXGroupID=null, JMS_OracleDeliveryMode=2, JMSXUserID=playliste, JMSExpiration=0, JMSReplyTo=null},
BodyType:byte[], Body:<?xml version="1.0" encoding="UTF-8" standalone="yes"?><Publication>hidden</Publication>]

The exchange gets send (Evenen when using Oracle AQ) ;-) to the seda:audit endpoint and the
auditMessageDAO gets called. Body is bound to correct payload but the header element JMSMessageID
is null. If i change the parameter to include @Headers Map the parameter is still null.

Current workaround is to use the Message, or Exchange as parameter, but then my pojo will
have dependencies on Camel - ok for now.

See thread : http://old.nabble.com/wiretap-getting-header-value-ts27238444.html for further
details.
