SOA 11g- Set Custom JMS Header properties In Mediator & BPEL

In this post, I will show you how you can set custom JMS header properties in Mediator and BPEL components.

By Default a JMS message includes a number of header fields that contain information used to identify and route messages. The supported headers for an incoming message are:

Ø   JMSCorrelationID

Ø   JMSDeliveryMode

Ø   JMSExpiration

Ø   JMSMessageID

Ø   JMSPriority

Ø   JMSRedelivered

Ø   JMSTimestamp

Ø   JMSType

But we can also set Custom properties.

Mediator: To set custom JMS header property in Mediator follows below steps.

Ø  Open .mplan file and click on assign activity. Here we are defining new custom header property (city).

Ø  To set city custom header property choose “jca.jms.JMSProperty” and append “.city” to it. You can assign any expression or hard-code this property value.

  

BPEL: To set custom JMS header property in BPEL follows below steps.

·         Go to *.bpel file, check the invoke code and add a new property called jca.jms.JMSProperty.city, for instance:

<invoke name="Invoke1" inputVariable="Invoke1_Produce_Message_InputVariable"

            partnerLink="Produce_Message" portType="ns1:Produce_Message_ptt"

            operation="Produce_Message" bpelx:invokeAsDetail="no">

              <bpelx:inputProperty name="jca.jms.JMSProperty.city" variable="cityVar"/>

 </invoke>

  

Currently this property is equal to cityVar but you can also use expression to assign value to city property.

              <bpelx:inputProperty name="jca.jms.JMSProperty.city" expression="2"/>

Remember you will not find this property in header tab, you need to manually set this property in *.bpel file for specific invoke.

When you will run the composite, you will see custom JMS header property at admin console for that queue.
