There is an IBM supplied dll (since v5.3 Fixpack8) on Windows called amqmdnet.dll, which is a .NET assembly providing an IBM supported model for MQSeries. (Reference) It is usually located in C:Program FilesIBMWebSphere MQbinamqmdnet.dll

I have done extensive testing with a sample program. The program was compiled for different frameworks and tested: 2.0 - works 3.0 - works 3.5 - works 4.0 - no This is the sample program. The MQ client version we use is 7.0.1.3. I could use some suggestions here guys. Back to top: lancelotlinc. For example using the MQ connection sample program, amqscnxc, run: amqscnxc -x host.xx.xx.com(port) -c SYSTEM.DEF.SVRCONN QueueManagerName If the FQDN does not resolve the problem, contact your System Administrator to investigate the issue further. On the WebSphere MQ MQI client workstation, use the amqsputc sample program to put a message on the queue at the server workstation. Use the amqsgetc sample program to get the message from the queue back to the client. This example is a simple JMS client application: Java Message Service JMS « J2EE « Java. On the WebSphere MQ MQI client workstation, use the amqsputc sample program to put a message on the queue at the server workstation. Use the amqsgetc sample program to get the message from the queue back to the client. I am beginner in web sphere mq programming. Any one has sample tutorial for connecting mq queue to java simple application. For Websphere MQ tutorial [closed.

I have never seen a sample on how to configure a Client channel to use SSL. Can sameone provide a pointer to a sample where MQ Client channel using SSL is configured? I have both manuals: a) MQ CLient b) MQ Security but there is no such code there. Any DeveloperWorks article? ( there are few with JMS, but I use 'normal' Client ) Thanks.

If you need more direction, there are several examples on how to communicate with MQ from .NET on CodeProject:

Also, there's this walkthrough that could be helpful: http://www.c-sharpcorner.com/UploadFile/pk_khuman/AquickstartCsharpWebsphereMQ07112006024017AM/AquickstartCsharpWebsphereMQ.aspx

You can connect using the .NET libraries provided by IBM; however, they require you to install the WebSphere MQ Client on every server you deploy your solution to. (lame)

If using WebSphere MQ, the machine used to run the XMS application must be installed with the WebSphere MQ Client V7.0.1.0 or later

You can avoid this by converting a few Java libraries using IKVM (www.ikvm.net).

The whole process should only take about 15 minutes.

You'll still need to download and install the client on your development box so that you can get the JAR files. After you convert them, you can uninstall the client.

Here are the steps

1) Get JARs

Download WebSphere MQ V7.5 Client: http://www-304.ibm.com/support/docview.wss?uid=swg24032744
Install the MQ client: You only need to install the 'Java and .Net Messaging and Web Services'.

2) Convert JARs

Download IKVM: www.ikvm.net
Extract the IKVM files (e.g. c:toolsIKVM).
Open Win command prompt
- Execute command: set path=%path%;c:toolsIKVMbin
- Execute command: cd C:Program Files (x86)IBMWebSphere MQjavalib
- Execute command: ikvmc -target:library -sharedclassloader { com.ibm.mq.jmqi.jar } { com.ibm.mqjms.jar } { dhbcore.jar } { jms.jar }

3) Copy JARs

Open windows explorer.
Navigate to: C:Program Files (x86)IBMWebSphere MQjavalib
Copy the following files:
- **com.ibm.mq.jmqi.dll
- com.ibm.mqjms.dll
- jms.dll**
Navigate to: c:toolsIKVMbin
Copy the following files:
- **IKVM.Runtime.dll
- IKVM.OpenJDK.Core.dll**
Move the copied files to a 3rd Party folder in your project/solution.

4) References JARs

Reference the copied JARs. Please note that you can skip the previous Copy JARs step above and simply reference the libraries directly, if you like. The objective was to show that there were no other resources needed for proper execution.

The following is a very simple example of how you can use the libraries.

There are number of samples that come with MQ product install. Refer Nmqsput.cs for your case. When creating a new project you will need to add amqmdnet.dll as reference.

Not sure what version of MQ you are using. I am assuming you are using MQ v701. You can find the samples under tools folder of your MQ installation.

Websphere Mq Client

If are looking for JMS style of messaging in C#, then XMS .NET is worth looking at. You can find the samples of XMS .NET in the same folder as MQ samples. XMS .NET reference is here

I am new to using MQ, but need to do the seemingly simplest task. I need a Java client program to make a MQ connection and send a string over that connection to a server.
Here is what I know.
- I have installed the MQ Client v5.3 on Windows XP.
- I have received a .tab file from the server group.
- I have configured the environment properly, enabling me to use amqsputc to successfully send a message to the server.
Now comes the rub. I have been trying to use the sample MSender.java to write that same message from a Java program, but can't get to first base. If I try the following:
qMgr = new MQQueueManager( qManagerName );
I get the following error:
java.lang.UnsatisfiedLinkError: no mqjbnd05 in java.library.path
The file mqjbnd05 doesn't come with the client distribution, it comes with the full distribution. So I tried the following:
java.util.Hashtable props = new java.util.Hashtable();
props.put(MQC.TRANSPORT_PROPERTY, MQC.TRANSPORT_MQSERIES_CLIENT);
qMgr = new MQQueueManager( qManagerName, props );
Now it doesn't look for the server libraries, but I get a different error:
MQJE001: An MQException occurred: Completion Code 2, Reason 2059
MQJE011: Socket connection attempt refused
MQJE001: An MQException occurred: Completion Code 2, Reason 2059
MQJE011: Socket connection attempt refused
WMQ exception occurred : Completion code 2 Reason code 2059
I've been pulling my hair out for weeks, and can't get this to work. If anyone could help me get the simplest 'Hello MQ World' to work, I would be grateful.

Hi,
Happy to help but have to ask the obvious questions first.
2059 normally means that the queue manager is not available. can I assume that you have a) Created the queue manager using the crtmqm command (or whatever the command is these days) and b) started the queue manager (strmqm).
There also needs to be an mq listener running which I think was the runmqlsr -m <Qmgr> -p <port number> -t tcp (Im assuming your using TCP)
command.
Check these things and if your still having probs write back.

Wait up.. ignore last post (just read your post properly).
Have you set the following MQEnvironment properties correctly before trying the
MQQueueManager call..
MQEnvironment.hostname = 'my.mqsvr.com'; // host to connect to
MQEnvironment.port = 1414; // port to connect to.
// If I don't set this,
// it defaults to 1414
// (the default WebSphere MQ port)
MQEnvironment.channel = 'channel.name'; // the CASE-SENSITIVE
// name of the
// SVR CONN channel on
// the queue manager
MQQueueManager qMgr = new MQQueueManager('MYQMGR');

Also if you notice in the applet code below the properties have to be stored in the MQEnvironment object. In fact the code below should provide you with all you need to connect to the server. Good luck

import com.ibm.mq.*; // Include the MQSeries classes for Java package public class MQSample extends java.applet.Applet{ private String hostname = 'your_hostname'; // define the name of your // host to connect to private String channel = 'server_channel'; // define name of channel // for client to use // Note. assumes MQSeries Server // is listening on the default // TCP/IP port of 1414 private String qManager = 'your_Q_manager'; // define name of queue // manager object to // connect to. private MQQueueManager qMgr; // define a queue manager object // When the class is called, this initialization is done first. public void init() { // Set up MQSeries environment MQEnvironment.hostname = hostname; // Could have put the // hostname & channel MQEnvironment.channel = channel; // string directly here! MQEnvironment.properties.put(MQC.TRANSPORT_PROPERTY,//Set TCP/IP or server MQC.TRANSPORT_MQSERIES);//Connection } // end of init public void start() { try { // Create a connection to the queue manager qMgr = new MQQueueManager(qManager); // Set up the options on the queue we wish to open.. // Note. All MQSeries Options are prefixed with MQC in Java. 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 system_default_local_queue = qMgr.accessQueue('SYSTEM.DEFAULT.LOCAL.QUEUE', openOptions, null, // default q manager null, // no dynamic q name null); // no alternate user id // Define a simple MQSeries message, and write some text 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 system_default_local_queue.put(hello_world,pmo); // get the message back again.. // First define a MQSeries 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. system_default_local_queue.get(retrievedMessage, gmo); // 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 system_default_local_queue.close(); // Disconnect from the queue manager qMgr.disconnect(); } // If an error has occurred in the above, try to identify what went wrong. // Was it an MQSeries error? catch (MQException ex) { System.out.println('An MQSeries 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 start } // end of sample

Hi all
I know this is a very old post but I am getting the same error. I am rtying to connect to a remote host, my code looks exactly like the Rpb gave but i still get this error.

I am connecting to remote host so why is it looking for this dll here locally. In case of a remote host it should not look for dlls, this is what i think.
I will appreciate any help. I have searched the net and most of the time they say to change your Queue binding to Client, which doesnt work in my case as I dont have a local MQ server.
Thanks in advance.
