   Run ant.

Procedure 12.2. Task

1. Configure the JMS Provider

   To configure JBoss Messaging, open the configuration file in a text editor: vi jboss-esb.xml.
2. Modify these settings:

   jndi-URL="localhost”
   	jndi-context-factory="org.jnp.interfaces.NamingContextFactory"
   	connection-factory="ConnectionFactory"
   	destination-type="queue"
   	destination-name="queue/myqueue"

   Important

   Always include the jboss-messaging-client.jar file on the class-path. (This file is found in the SOA_ROOT/jboss-as/client/jboss-messaging-client.jar archive.)

   Note

   If you want to use load balancing and fail-over capabilities, you must configure JBoss Messaging for clustering. This functionality is constantly evolving. To learn how to configure it, please consult the JBoss Messaging documentation.
3. Check that JBoss Messaging's Service Binding Manager configuration matches that found in the SOA_ROOT/seam/bootstrap/deploy/remoting-service.xml file.

Procedure 12.5. Task

1. Configure the Adapter

   The adapter name is wmq.jmsra.rar. Copy this file into the JBoss Enterprise SOA Platform's SOA_ROOT/jboss-as/server/PROFILE/deploy directory.

2. Check the Context Factory

   Ensure that the initial context factory is com.ibm.mq.jms.context.WMQInitialContextFactory.

3. Configure the QueueManager

   Ensure that the queueManager configuration is in the <activation-config>. You will need to configure a queue manager in your own Websphere MQ installation. (Note that all of your destination queues are configured in your queue manager.)

4. Configure the Channel

   Ensure that the channel configuration is in the <activation-config> property.

   Note

   You can configure a queue manager to use a number of different types of channel. Clients connect through server connection channels. A default server connection channel (SYSTEM.DEF.SVRCONN), is added as part of the Websphere MQ installation but it is a good idea to also create your own dedicated channels, especially if you are using extended (XA) transactions.

5. Configure the transportType

   Edit the transportType. The configuration for this is in the <activation-config> property. Websphere MQ supports two transport types ( Client and Binding).

6. Edit the Settings

   Open the configuration file in a text editor and edit it.
   Here is an example of a <jms-jca-provider> configuration. It shows how to set a gateway provider configuration:

   <jms-jca-provider adapter="wmq.jmsra.rar" connection-factory="MyAppXAConnectionFactory" jndi-context-factory="com.ibm.mq.jms.context.WMQInitialContextFactory" name="WMQ-JCA">
   	<property name="max-xa-sessions-per-connection" value="1"/>
   		<jms-bus busid="quickstartGwChannel">
   		<jms-message-filter dest-name="QUEUE1_JMS" dest-type="QUEUE" transacted="true"/>
   		</jms-bus>
   			<activation-config>
   				<property name="queueManager" value="TQM"/>
   				<property name="channel" value="Q1CONN"/>
   				<property name="hostName" value="localhost"/>
   				<property name="port" value="1414"/>
   				<property name="transportType" value="CLIENT"/>
   			</activation-config>
   </jms-jca-provider>
   

   Copy to Clipboard Toggle word wrap

   Note

   It is actually the <jms-listener> configuration that determines the gateway/message-aware characteristics of a listener. However, as far as Websphere MQ is concerned, this is only of use as a gateway listener provider. In other words, this configuration would not work as a message-aware listener for Websphere MQ. This is because it does not specify an appropriate JNDI provider URL (as used by the ServiceInvoker) for routing ESB messages to the destinations (buses) defined on the provider.

7. Configure the JCA Adapter

   The <activation-config> configures the JCA adapter so that it obtains messages from the destinations. It does not determine how messages are to be delivered to the destinations. Here is an example of a configuration that could be used as a message-aware listener's provider:

   <jms-jca-provider adapter="wmq.jmsra.rar" connection-factory="MyAppXAConnectionFactory" jndi-URL="localhost:1414/CHANX" jndi-context-factory="com.ibm.mq.jms.context.WMQInitialContextFactory" name="WMQ-JCA">
   	<property name="max-xa-sessions-per-connection" value="1"/>
   		<jms-bus busid="quickstartEsbChannel">
   			<jms-message-filter dest-name="QUEUE2_JMS" dest-type="QUEUE" transacted="true"/>
   		</jms-bus>
   	<activation-config>
   		<property name="queueManager" value="TQM"/>
   		<property name="channel" value="Q2CONN"/>
   		<property name="hostName" value="localhost"/>
   		<property name="port" value="1414"/>
   		<property name="transportType" value="CLIENT"/>
   	</activation-config>
   </jms-jca-provider>
   

   Copy to Clipboard Toggle word wrap

8. Creating a Standard JMS Provider

   The settings for creating a standard JMS provider configuration are similar:

   <jms-provider connection-factory="MyAppConnectionFactory" jndi-URL="localhost:1414/CHAN1" jndi-context-factory="com.ibm.mq.jms.context.WMQInitialContextFactory" name="JMS">
   	<jms-bus busid="quickstartGwChannel2">
   		<jms-message-filter dest-name="QUEUE3_JMS" dest-type="QUEUE"/>
   	</jms-bus>
   </jms-provider>
   

   Copy to Clipboard Toggle word wrap

   Note

   With the standard provider, there is neither an adapter nor any <activation-config> configurations. Listeners receiving messages from the destinations defined in a standard provider do not use a JCA Adapter Inflow to obtain the messages. Instead, they need to use JNDI to find the destination and obtain the messages. This means that, for Websphere MQ, the jndi-URL must always be specified (remember that for JCA it is only required for destinations that service a Message-Aware listener).

9. Save

   Save the file and exit.

Procedure 12.6. Task

1. Edit the JMSRouter Configuration

   Open the JMSRouter's configuration file in a text editor and modify the settings in your jboss-esb.xml. Here is an example of a JMSRouter configuration for routing messages to Websphere MQ from inside an ESB action pipeline:

   <action class="org.jboss.soa.esb.actions.routing.JMSRouter" name="routeToORDERSQueue">
   	<property name="jndi-context-factory" value="com.ibm.mq.jms.context.WMQInitialContextFactory"/>
   	<property name="jndi-URL" value="wmqserver:1414/CHANX"/>
   	<property name="connection-factory" value="WMQConnectionFactory"/>
   	<property name="jndiName" value="ORDERS"/>
   </action>

2. Save

   Save the file and exit.

Procedure 12.7. Task

1. Edit the jms-jca-provider Configuration

   Edit the jboss-esb.xml file in a text editor. Here is how the jms-jca-provider configuration would look for an Extended Transaction Client configuration. (In this example, the XA Connection Factory that has been configured in the WMQ JNDI namespace is called WMQXAConnectionFactory.)

   Note

   Inflow related configurations (adapter, <activation-config> etc) were intentionally omitted as they are not relevant to the Extended Client configuration:

   <jms-jca-provider name="WMQ" connection-factory="WMQXAConnectionFactory"
   	jndi-URL="wmqserver:1414/CHANXA_SEND"
   	jndi-context-factory="com.ibm.mq.jms.context.WMQInitialContextFactory">
   		<property name="max-xa-sessions-per-connection" value="1" />
   			<jms-bus busid="ordersGwChannel">
   			<jms-message-filter dest-type="QUEUE" dest-name="ORDERS" transacted="true"/>
   			</jms-bus>
   				<activation-config>
   					<!--
   					Used by inflow... not relevant to client
   					See section on JMS and JCA.
   					-->
   		</activation-config>
   </jms-jca-provider>
   

   Copy to Clipboard Toggle word wrap

2. Configuring for Use with the JMSRouter

   This example shows how to use the same XA Connection Factory on the JMSRouter:

   <action name="routeToORDERSQueue" class="org.jboss.soa.esb.actions.routing.JMSRouter">
   <property name="jndi-context-factory"
   value="com.ibm.mq.jms.context.WMQInitialContextFactory"/>
   <property name="jndi-URL" value="wmqserver:1414/CHANXA_SEND"/>
   <property name="connection-factory" value="WMQXAConnectionFactory"/>
   <property name="jndiName" value="ORDERS"/>
   <property name="max-xa-sessions-per-connection" value="1"/>
   <!-- etc... -->
   </action>
   

   Copy to Clipboard Toggle word wrap

   Important

   An important point to note about Websphere MQ and XA is that it does not support both getting and putting messages concurrently on the same Queue Manager Channel. For this reason, it is a good idea to configure a dedicated channel for each component that gets or puts messages into a Websphere MQ destination in the context of XA transactions.
3. Set the max-xa-sessions-per-connection property in jboss-esb.xml to 1.

4. Save

   Save the file and exit.
5. Configure a dedicated queue manager channel for each component that obtains or sends messages to a Websphere MQ destination.
6. Make sure the GET and PUT properties on each of the Websphere MQ destinations are not set to Inhibit. (This can be happen when the destination is created and it results in the ESB being unable to obtain or send messages.)

Procedure 12.8. Task

1. Navigate to the bin directory: cd /opt/mqm/java/bin.
2. Launch JMSAdmin.
3. Use this program to administer your JNDI settings and obtain a ConnectionFactory for Plain JMS interactions.

   Note

Procedure 12.9. Task

1. Make a queue manager called QM1: crtmqm -q QM1
2. Start runmqsc: runmqsc QM1
3. Input the following settings when prompted:

   define channel (CH.1) chltype (RCVR) trptype (TCP)
   start channel (CH.1)
   define qlocal (Q1)
   define listener(QM1.LISTENER) trptype(TCP) port(30001) ipaddr(10.12.58.110)

1. To change the workflow so that services are published upon creation, click on the “Configure” tab and then select “Workflow”.
2. View the Workflow Definition, save it to your local disk, and then change the function type line under @create to <function type="publish" /> and the step attribute to “100”.
3. Save this.
4. Update the workflow to the local copy you have just saved.

• Use the "Search" option to find services. This feature also displays information about each service, including a description, its current state, its version number and the number of alerts it has generated. Services are registered in the SOA Service Workbench so manage them directly through its graphical user interface.

• If you encounter an error when configuring and updating the Workflow, you can verify it has been modified correctly by checking that its configuration has changed from the original configuration (which looked like this):

  <action id="1" name="@create">
