    Using WSMQ as part of ESB

    Michael Vilot Newbie

      Looks like the published code is incorrect.

      Configuration: jboss-4.0.4.GA with WSMQ 6.0, both running on Windoze. JBoss installer summary: Chosen installation packs

      jmx-core
      minimal
      binding-service
      client-deployer-service
      dynclassloader-service.xml
      ear-deployer
      ejb-timer-service
      ejb-deployer
      hsqldb-ds
      jboss-local-jdbc.rar
      javamail
      jbossretro
      jbossws14
      jca-service
      jdbc-metadata-service
      jbossmq-service
      jms-asf-rar
      jms-injvm-invoker
      jms-socket-invoker
      jmx-console
      invokers-service
      jmx-invoker-service
      jta-service
      usertx-service
      mail-inflow-adaptor
      naming
      security
      war-deployer
      jboss-remoting

      Configured the -ds.xml per http://wiki.jboss.org/wiki/Wiki.jsp?page=IntegrationWithWebSphereMQSeries
      Compiled and deployed the .sar:
      INFO [ResponseQueue] Bound to JNDI name: queue/ResponseQueue
      INFO [RequestQueue] Bound to JNDI name: queue/RequestQueue
      INFO [ConnectionFactoryBindingService] Bound ConnectionManager 'jboss.jca:service=ConnectionFactoryBinding
      ,name=WSMQJms' to JNDI name 'java:WSMQJms'

      From the jmx-console, JNDIView 1st throws the following exception chain (no HA or EJB cache-invalidation-service support in this configuration):
      ERROR [JNDIView] JNDIView.getHAJndiAttributes() failed

      Now, here's the fun part. Deploying the MDB provokes the following:
      INFO [EjbModule] Deploying WSMQMDB
      WARN [JMSContainerInvoker] JMS provider failure detected for WSMQMDB
      org.jboss.deployment.DeploymentException: Error during queue setup; - nested throwable: (java.lang.ClassCastException: o
      rg.jboss.resource.adapter.jms.JmsConnectionFactoryImpl)

       at org.jboss.ejb.plugins.jms.JMSContainerInvoker.startService(JMSContainerInvoker.java:839)
      ...

      The key settings are in the -ds.xml <connection-factories> tag:
      <mbean code="org.jboss.jms.jndi.JMSProviderLoader"
       name="jboss.mq:service=JMSProviderLoader,name=WSMQJMSProvider">
       <attribute name="ProviderName">WSMQJMSProvider</attribute>
       <attribute name="ProviderAdapterClass">org.jboss.jms.jndi.JNDIProviderAdapter</attribute>
       <!-- The queue connection factory -->
       <attribute name="QueueFactoryRef">WSMQQueueConnectionFactory</attribute>
       <!-- The topic factory -->
       <attribute name="TopicFactoryRef">WSMQTopicConnectionFactory</attribute>
       </mbean>
      
       <no-tx-connection-factory>
       <jndi-name>WSMQJms</jndi-name>
       <rar-name>jms-ra.rar</rar-name> <!-- JCA 1.5 -->
       <use-java-context>true</use-java-context>
       <connection-definition>org.jboss.resource.adapter.jms.JmsConnectionFactory</connection-definition>
       <!-- ClassCastException: org.jboss.resource.adapter.jms.JmsConnectionFactoryImpl -->
       <max-pool-size>20</max-pool-size>
       <!-- These are JBoss-specific properties for a ManagedConnectionFactory -->
       <!-- MUST MATCH Mbean JNDI NAME (overrides default "java:/DefaultJMSProvider") -->
       <config-property name="JmsProviderAdapterJNDI" type="java.lang.String">WSMQJMSProvider</config-property>
       <config-property name="SessionDefaultType" type="java.lang.String">javax.jms.Queue</config-property>
       <config-property name="UserName" type="java.lang.String">User</config-property>
       <config-property name="Password" type="java.lang.String">password</config-property>
       </no-tx-connection-factory>

      Looks like the JmsConnectionFactoryImpl class _does_ exist in the jms-ra.jar deployed inside the jms-ra.rar.

      Any ideas why the ClassCastException is happening?
