The WSO2 ESB JMS inbound protocol is a multi-tenant capable alternative to the WSO2 ESB JMS transport. The JMS inbound protocol implementation requires an active JMS server instance to be able to receive messages, and you need to place the client JARs for your JMS server in the ESB classpath.

The recommended JMS servers are WSO2 Message Broker or Apache ActiveMQ, but other implementations such as Apache Qpid and Tibco are also supported.

Configuration parameters for a JMS inbound endpoint are XML fragments that represent JMS connection factories.

Following is a sample JMS inbound endpoint configuration:

<inboundEndpoint xmlns="http://ws.apache.org/ns/synapse" name="jms" sequence="request" onError="fault" protocol="jms" suspend="false">
      <parameters>
         <parameter name="interval">1000</parameter>
         <parameter name="coordination">true</parameter> 
         <parameter name="transport.jms.Destination">ordersQueue</parameter>
         <parameter name="transport.jms.CacheLevel">1</parameter>
         <parameter name="transport.jms.ConnectionFactoryJNDIName">QueueConnectionFactory</parameter>
         <parameter name="sequential">true</parameter>
         <parameter name="java.naming.factory.initial">org.apache.activemq.jndi.ActiveMQInitialContextFactory</parameter>
         <parameter name="java.naming.provider.url">tcp://localhost:61616</parameter>
         <parameter name="transport.jms.SessionAcknowledgement">AUTO_ACKNOWLEDGE</parameter>
         <parameter name="transport.jms.SessionTransacted">false</parameter>
         <parameter name="transport.jms.ConnectionFactoryType">queue</parameter>
      </parameters>
   </inboundEndpoint>

The parameters interval and coordination are common to all polling inbound endpoints. For descriptions of these parameters, see Common polling inbound endpoint parameters.

transport.jms.ReceiveTimeout

The time to wait for a JMS message during polling.
Set this parameter value to a negative integer to wait indefinitely. Set it to zero to prevent waiting.
NoThe number of milliseconds to wait.1
transport.jms.ContentTypeHow the inbound listener should determine the content type of received messages. Priority is always given to the JMS message type.NoA simple string value, in which case the transport listener assumes that the received messages always have the specified content type, or a set of rules. For more information, see http://axis.apache.org/axis2/java/transports/jms.html#Service_configuration.-

transport.jms.retry.duration

The retry interval to reconnect to the JMS server.

No

Retry interval in miliseconds.

transport.jms.RetriesBeforeSuspension

Note

This parameter is introduced via the WUM update for WSO2 ESB 4.9.0, released on the 9th of January 2018.
Note that you can deploy a WUM update into production only if you have a paid subscription. If you do not have a paid subscription, you can use this parameter when the next version of the product is released.

The number of consecutive mediation failures after which polling should be suspended.NoSpecify any positive numerical value based on your requirement. Polling will be suspended when the mediation failure count reaches the specified value. -

transport.jms.PollingSuspensionPeriod

Note

This parameter is introduced via the WUM update for WSO2 ESB 4.9.0, released on the 9th of January 2018.
Note that you can
deploy a WUM update into production only if you have a paid subscription. If you do not have a paid subscription, you can use this parameter when the next version of the product is released.

The period of time that polling is to be suspended when the transport.jms.RetriesBeforeSuspension parameter is set.NoSpecify a required time period in milliseconds.60000

Note

To subscribe to topics, set the value of transport.jms.CacheLevel to 3.
