Configure IBM WebSphere MQ 7.0.1.3/ 6.0 (Messaging service) with WSO2 ESB in Windows system

This blog is on some hands on experience of installing IBM Websphere MQ (version 6.0 and 7.0.1.3) the JMS messaging service with WSO2 ESB- the Enterprise Service Bus application

 This includes 2 parts

1.  IBM MQ installation and configuration
2.  ESB configuration

Please refer following source for an in-depth explanation of installing in Linux based system:

 1. IBM MQ installation and configuration

1. Install IBM MQ software using following guide

http://publib.boulder.ibm.com/infocenter/sametime/v8r0/index.jsp?topic=/com.ibm.help.sametime.advanced.doc/stv_inst_mq_appl_win_t.html

2.  Start ‘IBM WebSphere MQ Explorer, create a new queue manager. Check ‘make this the default queue manager’. Leave rest of the info as it is

3.  Go to newly created Q manager and expand the list, create a new local queue

4. Expand ‘Advanced’ sub tree and add a ‘server-connection’ channel

5. Add a TCP listener from ‘Advanced’ sub tree. LISTENER.TCP is added by default.

6. Go to C:\Program Files\IBM\WebSphere MQ\java\bin, and invoke IVT app

        

    Run : IVTRun.bat –nojndi

If successful you will see the following

7. Run : IVTRun.bat -nojndi -client -m mymgr -host localhost -channel mychannel

If successful you will see the following

8. Go to C:\Program Files\IBM\WebSphere MQ\java\bin, open 'JMSAdmin.config' file and do  following 
             1. INITIAL_CONTEXT_FACTORY- uncomment this line
             ex: INITIAL_CONTEXT_FACTORY=com.sun.jndi.fscontext.RefFSContextFactory
             2. PROVIDER_URL - point to an empty folder

             Ex: PROVIDER_URL=file:/D:/JNDI-Directory

9. Run the "IVTSetup.bat" in the command prompt to create the default set of JNDI bindings

If successful you will see the following

10. Now run the IVTRun tool as follows

IVTRun.bat -url "file:/D:/JNDI-Directory" -icf com.sun.jndi.fscontext.RefFSContextFactory

11. By now we have enabled and verified JNDI support. Let's use the JMSAdmin tool to make some modifications in the JNDI bindings

Start jmsadmin.bat in C:\Program Files\IBM\WebSphere MQ\java\bin from the colsole, Run following commands

 ALTER QCF(ivtQCF) TRANSPORT(CLIENT)

 ALTER QCF(ivtQCF) QMGR(mymgr)

Now let’s get to configure the ESB.

ESB configuration

1. Copy the following jar files from C:\Program Files\IBM\WebSphere MQ\java\lib to D:\wso2esb-2.1.0\repository\components\lib

• com.ibm.mqjms.jar

• fscontext.jar

• providerutil.jar

• com.ibm.mq.jmqi.jar

• dhbcore.jar

If you are using IBM MQ 6.0 additionally following jars need to be added

.(you might not find com.ibm.mq.jmqi.jar in MQ 6.0 version)

com.ibm.mq.jar

connector.jar

Optionally you might need the following jars as well.(But in our case they we not required)

jms.jar

jndi.jar

jta.jar

ldap.jar

2. Enable the JMS listener in the axis2.xml. Configure the default and userdefined connection factories as follows

Here the connection factory name is ‘SQProxyCF’ which will be used by the STOCKQUOTEPROXY proxy service in the 250 sample

 If you are using IBM MQ 6.0 , then you might probably add this line as well.

 Here MQ 6.0 uses JMS Spec version 1.0.2b instead of 1.1

3. Note that we have specified a queue named ‘bogusq ‘as the default destination. This is because we need to use ivtQ for our proxy service only. If we use 'ivtQ' here all the services deployed in ESB (XKMS, echo, wso2carbon-sts) will start listening on the same queue.

You also need to login to JMSAdmin and create the queue named ' bogusq'. In JMSAdmin shell run the following commands.

• DEFINE Q(bogusq) QMGR(mymgr)

• ALTER Q(bogusq) QUEUE(localq)

Here ‘localq’ is the one we created earlier

4. Go to SYNAPSE_HOME/samples/axis2Client/src/samples/userguide and open the GenericJMSClient.java source file. Make the following changes in the code.

• Set the jms_dest property default value to "ivtQ" (line 45)

• Set the java.naming.provider.url to "file:/var/mqm/jndi" (line 82)

• Set the java.naming.factory.initial to "com.sun.jndi.fscontext.RefFSContextFactory" (line 85)

• Set the lookup key to "ivtQCF" (line 89)

5. Start sample 250

• wso2esb-samples.bat -sn 250

6. Add following parameter to the synapse config in the proxy service block:

7. Start sample axis2server with SimpleStockQuoteService service

8. Run the following in the client

• ant jmsclient -Djms_type=pox -Djms_payload=IBM
