Hi Ulises,
Attached herewith is a sample Java application that PUTs a message to an MQ
queue and then reads and displays the same. Replace the parameters with your
own as indicated in the sample.
You will need "mq.jar" and/or "mqjms.jar" if you intend to use JMS too. You
can get these jar files from the MA88 supportPak from IBM for MQSeries.
========================================
import com.ibm.mq.*; // Include the MQ package
public class MQSample
{
private String hostname = "<your host name or IP>"; // define the
name of your host to connect to
private String channel = "<your channel name>"; // define name
of channel for client to use
private int port = 1414;
// Note. assumes MQ Server is listening on
// the default TCP/IP port of 1414
private String qManager = "<your queue manager name>"; // define name
of queue manager object to
// connect to.
private MQQueueManager qMgr; // define a queue
manager object
// When the class is called, this initialisation is done first.
public MQSample()
{
// Set up MQ environment
MQEnvironment.hostname = hostname; // Could have put the
hostname & channel
MQEnvironment.channel = channel; // string directly
here!
MQEnvironment.port = port;
try
{
qMgr = new MQQueueManager(qManager);
}
catch (Exception ex)
{
System.out.println("Error in connecting the q
manager....");
}
}
public static void main(String args[])
{
try {
// Create a connection to the queue manager
// Set up the options on the queue we wish to open...
// Note. All MQ Options are prefixed with MQC in Java.
MQSample mqsamp = new MQSample();
int openOptions = MQC.MQOO_INPUT_AS_Q_DEF | MQC.MQOO_OUTPUT ;
// Now specify the queue that we wish to open, and the open options...
MQQueue dss_reply_queue =
mqsamp.qMgr.accessQueue("<your queue name>", openOptions, "",
"", ""); // default q manager
// no
dynamic q name
// no
alternate user id
// Define a simple MQ message, and initialise it in UTF format..
MQMessage hello_world = new MQMessage();
hello_world.writeUTF("Hello World!");
// specify the message options...
MQPutMessageOptions pmo = new MQPutMessageOptions(); // accept the
defaults, same
// as
MQPMO_DEFAULT constant
// put the message on the queue
dss_reply_queue.put(hello_world,pmo);
// get the message back again...
// First define a MQ message buffer to receive the message into..
MQMessage retrievedMessage = new MQMessage();
retrievedMessage.messageId = hello_world.messageId;
// Set the get message options..
MQGetMessageOptions gmo = new MQGetMessageOptions(); // accept the
defaults
// same as MQGMO_DEFAULT
// get the message off the queue..
dss_reply_queue.get(retrievedMessage, gmo, 100); // max message
size
// And prove we have the message by displaying the UTF message text
String msgText = retrievedMessage.readUTF();
System.out.println("The message is: " + msgText);
// Close the queue
dss_reply_queue.close();
// Disconnect from the queue manager
mqsamp.qMgr.disconnect();
}
// If an error has occured in the above, try to identify what went
wrong.
// Was it an MQ error?
catch (MQException ex)
{
System.out.println("An MQ error occurred : Completion code " +
ex.completionCode +
" Reason code " + ex.reasonCode);
}
// Was it a Java buffer space error?
catch (java.io.IOException ex)
{
System.out.println("An error occurred whilst writing to the message
buffer: " +
ex);
}
} // end of main
} // end of MQSample
========================================
I hope this helps!
Best regards,
Urvesh.

Subject: Jps(or Servlet) with MQ-SERIES in windows NT.
Hello to all:
I need to connect a java component (jsp or servlet) with an application by
Mq-Series (the application provides a mq-series interface), but I don't know
what is necessary to make this connection.
Does somebody have an example in order to make the connection?
I'm working in Windows NT 4.0, with tomcat.
Please any aid I thank for them, since it's an urgent subject.
Thank you very much,
Ulises.
