Well, IBM provides two types of Java Bindings
1. MQI Java Bindings
2. JMS Implementation
Based on the need you can use either or both.
These apis are free for development and is provided with the MQSeries CD, if you have bought.
If you need links for downloading and installation, then follow this link. (copy and paste on ur fav. browser.)
Down load the MQI for Java.

Sample Program

import com.ibm.mq.pcf.*;
import java.io.*;
public class MQConnector
{
private PCFAgent connectorAgent;
private static final String Q_MANAGER="QM_ganesh";
private static final String Q_LOCAL="XML_Q";
public MQConnector() throws MQException, IOException
{
PCFAgent agent = new PCFAgent ("<host name>", 1414, "ORDERS");
MQMessage [] responses;
PCFParameter [] parameters =

new MQCFST (CMQC.MQCA_Q_NAME, "*"),
new MQCFIN (CMQC.MQIA_Q_TYPE, MQC.MQQT_LOCAL)
};
MQCFH cfh;
MQCFSL cfsl;
responses = agent.send (CMQCFC.MQCMD_INQUIRE_Q_NAMES, parameters);
cfh = new MQCFH (responses [0]);
if (cfh.reason == 0)
{
cfsl = new MQCFSL (responses [0]);
for (int i = 0; i < cfsl.strings.length; i++)
{
System.out.println ("Queue: " + cfsl.strings [i]);
}
}
else
{
throw new MQException (cfh.compCode, cfh.reason, agent);
}
}
public static void main(String[] args)
{
try
{
MQConnector mq=new MQConnector();
}
catch(MQException mqe)
{
mqe.printStackTrace();
}
catch(IOException ioe)
{
ioe.printStackTrace();
}
}
}
If you use the JMS version (where u create topic connection factory or Queue Connection factory, then u will be using JMS version.
IF you are using J2EE architecture, u can extend Message Driven Bean with MQSeries JMS impl or Session beans can invoke hellper classes which actually connect to MQSeries and do a put and get message (two famous operation on MOM).
Hope this helps and my two cents ..
Thanks
