Connecting to Oracle WebLogic

This section describes how to configure WSO2 Micro Integrator to connect with Oracle WebLogic 10.3.4.0.

Starting WebLogic and WSO2 Micro Integrator

1. Download and set up Oracle WebLogic Server.
2. Download and start WSO2 Micro Integrator .
3. Wrap the weblogic client jar and build a new OSGi bundle using the following pom.xml. The exporting of javax.jms package and javax.xml.namespace package of the client JAR should be prevented.
4. Copy the client libraries file (wlfullclient.jar) from the WEBLOGIC_HOME/wlserver_XX/server/lib directory to the MI_HOME/dropins directory.

Configuring the WebLogic server

Configure the required connection factories and queues in WebLogic. An entry for a JMS queue would look like the following. The configuration files can be found inside the WEBLOGIC_HOME/user_projects/domains/<DOMAIN_NAME>/config/jms file. Alternatively you can configure using the WebLogic web console, which can be accessed through http://localhost:7001 with default configurations.

<queue name="wso2MessageQueue">
  <sub-deployment-name>jms</sub-deployment-name>
  <jndi-name>jms/wso2MessageQueue</jndi-name>
</queue>

When you start the WebLogic server with the above changes, you can see the following on STDOUT.

<Jun 25, 2013 11:20:02 AM IST> <Notice> <WebLogicServer> <BEA-000331> <Started WebLogic Admin Server "AdminServer" for domain "wso2" running in Development Mode> 
<Jun 25, 2013 11:20:02 AM IST> <Notice> <WebLogicServer> <BEA-000365> <Server state changed to RUNNING> 
<Jun 25, 2013 11:20:02 AM IST> <Notice> <WebLogicServer> <BEA-000360> <Server started in RUNNING mode> 

Setting up the JMS listener amd Sender

If you want the Micro Integrator to receive messages from Weblogic instance, or to send messages to a Weblogic instance, you need to update the deployment.toml file with the relevant connection parameters.

Add the following configurations to enable the JMS sender and listener with Weblogic connection parameters.

[transport.jms]
sender_enable = true

[[transport.jms.listener]]
name = "myQueueConnectionFactory"
parameter.initial_naming_factory = "weblogic.jndi.WLInitialContextFactory"
parameter.provider_url = "t3://localhost:7001"
parameter.connection_factory_name = "jms/myConnectionFactory"
parameter.connection_factory_type = "queue"
parameter.username = "weblogic"
parameter.password = "admin123"

[[transport.jms.listener]]
name = "default"
parameter.initial_naming_factory = "weblogic.jndi.WLInitialContextFactory"
parameter.provider_url = "t3://localhost:7001"
parameter.connection_factory_name = "jms/myConnectionFactory"
parameter.connection_factory_type = "queue"
parameter.username = "weblogic"
parameter.password = "admin123"

Setting up a message store

Create a message store using a configuration similar to the following:

<messageStore class="org.wso2.carbon.message.store.persistence.jms.JMSMessageStore"
        name="wso2MessageStore">       
    <parameter name="java.naming.factory.initial">weblogic.jndi.WLInitialContextFactory</parameter>
    <parameter name="store.jms.cache.connection">false</parameter>
    <parameter name="store.jms.password">admin123</parameter>
    <parameter name="java.naming.provider.url">t3://localhost:7001</parameter>
    <parameter name="store.jms.ConsumerReceiveTimeOut">300</parameter>
    <parameter name="store.jms.connection.factory">jms/myConnectionFactory</parameter>
    <parameter name="store.jms.username">weblogic</parameter>
    <parameter name="store.jms.JMSSpecVersion">1.1</parameter>
    <parameter name="store.jms.destination">jms/wso2MessageQueue</parameter>
</messageStore>

JMS Producer Proxy Service

Use the following proxy service configuration in WSO2 Micro Integrator to publish messages to the WebLogic queue:

<proxy xmlns="http://ws.apache.org/ns/synapse"
       name="WeblogicJMSSenderProxy"
       transports="http"
       statistics="disable"
       trace="disable"
       startOnLoad="true">
   <target>
      <inSequence>
         <property name="Accept-Encoding" scope="transport" action="remove"/>
         <property name="Content-Length" scope="transport" action="remove"/>
         <property name="Content-Type" scope="transport" action="remove"/>
         <property name="User-Agent" scope="transport" action="remove"/>
         <log level="custom">
            <property name="STATUS:"
                      value="------Message send by WeblogicJMSConsumerProxy--------"/>
         </log>
         <property name="OUT_ONLY" value="true"/>
         <property name="FORCE_SC_ACCEPTED" value="true" scope="axis2"/>
         <send>
            <endpoint>
               <address uri="jms:/jms/TestJMSQueue1?transport.jms.ConnectionFactoryJNDIName=jms/TestConnectionFactory1&amp;java.naming.factory.initial=weblogic.jndi.WLInitialContextFactory&amp;java.naming.provider.url=t3://localhost:7001&amp;transport.jms.DestinationType=queue"/>
            </endpoint>
         </send>
      </inSequence>
      <outSequence>
         <send/>
      </outSequence>
   </target>
   <description/>
</proxy>

JMS Consumer Proxy Service

Use the following proxy service configuration in WSO2 Micro Integrator to read messages from the WebLogic queue:

<proxy xmlns="http://ws.apache.org/ns/synapse"
       name="WeblogicJMSConsumerProxy"
       transports="jms"
       statistics="disable"
       trace="disable"
       startOnLoad="true">
   <target>
      <inSequence>
         <log level="custom">
            <property name="STATUS:"
                      value="------Message consumed by WeblogicJMSConsumerProxy--------"/>
         </log>
         <log level="full"/>
      </inSequence>
      <outSequence>
         <send/>
      </outSequence>
   </target>
   <parameter name="transport.jms.Destination">jms/TestJMSQueue1</parameter>
   <description/>
</proxy>
