Can I use JMQ 2.0 in a java application?
Is it possible to have a stand alone iMQ client? I have a requirement where one of my applications which needs to communicate with iMQ runs on a different machine than the iMQ itself. I also need to have a separate JNDI repository for this application to look up administered objects. So in short I need to create a JNDI entry for an already existing Queue (or queueconnectionfactory) on an existing iMQ server. Also I need to know which libraries (jars) to copy to my application machine so that they can successfully access iMQ. I know I can do this for MQ series.
iMQ 2.0 does support both:
- installed only the client jar files
- using JNDI to store the connections objects
It is possible to have a standalone client. All of the jar files you
need for a client is available in the client runtime package
On solaris: you need to install the SUNWjqapi package on the client
system
On Linux:you will need the following libraries:
fscontext.jarjmq.jarjnet.jar ldapbp.jar
jaas.jar jms.jarjsse.jar providerutil.jar
jcert.jar jndi.jar ldap.jar
jms.jar -> is the jar which has the jms interfaces
jmq.jar -> has the iMQ jms implementation
jsse.jar -> is used for SSL comminication
other jars are used for ldap
On Windows: run the iMQ 2.0 installer and select a custom install
when the "select components" dialog is displayed, select
"client Runtime"
Once you install the client runtime, your clients will need
to connect to the remote broker. This can be done by:
1. specifying the broker name on the command line
(if you have changed the brokers portmapper port,
you may also need to specific the port with JMQBrokerHostPort)
the default port for the portmapper):
java -DJMQBrokerHostName=<brokerhost> <your class file> <your args>
e.g.
java -DJMQBrokerHostName=myhost MyApplication
2. Specifiy the broker host in an administered Connection Object
for directions on how to create an administered object, see:
Chapter 7 of the admininstrators guide
(doc/en/userguides/admin.pdf)
For directions on using administered objects, see
Chapter 3 of the developers guide
(doc/en/userguides/developer.pdf)
If you are using JMQ2.0 and planning to use http to communicate
with the broker, you will need to add one additional jar file:
jmqutil.jar
This restriction is lifted once the JMQ 2.0 SP1 patch is applied.
