SUMMARY

Using Microsoft Message Queue Server (MSMQ) ActiveX components from Java is similar to using any other ActiveX objects from the Java environment. Following are the basic "getting started" steps with Java and MSMQ ActiveX components.

MORE INFORMATION

How to Use ActiveX Components from Microsoft Visual J++ 1.1

"Using Java and COM" topic in Visual J++ Books Online describes how to use COM with Java. Visual J++ 1.1 includes several Java/COM samples.

What MSMQ ActiveX Components are Available

Read the information in MSMQ SDK, especially the following topics:

  • MSMQ Guide\MSMQ ActiveX Support
  • Using MSMQ\Using the ActiveX Components

How To Create an MSMQ Application Using Java Applet Wizard

Here are the basic "getting started" steps with Java and MSMQ ActiveX components using Microsoft Visual J++ 1.1, which is included with Microsoft Visual Studio 97. This project shows how to create an MSMQ queue using Java code:

  1. Create a basic Visual J++ project using Java Applet Wizard. Select "As an applet only" in Step 1, "HTML file" in Step 2, "multi-threaded" and "no animation" in Step 3, and then click Finish.

    This creates two source files in the project. One is a .java file for the java class and the other is an .html file for VBScript (given below):

          <html>
      <head>
      <title>MQJava</title>
      </head>
      <body>
      <hr>
      <applet
          code=MQJava.class
          name=MQJava
          width=320
          height=240 >
      </applet>
      <hr>
      <a href="MQJava.java">The source.</a>
      </body>
      </html>
  2. Run "Java Type Library Wizard" on "Microsoft Message Queue Object Library":

    The MSMQ installation program creates the registry entries for MSMQ ActiveX components and interfaces so that the typelib gets registered. Before building the project, make sure you run the Java Type Library Wizard from the Tools menu in DevStudio IDE. Select "Microsoft Message Queue Object Library" from the list, which creates the .class files in your Winnt\Java\Trustlib\Mqoa folder. The folder also contains a Summary.txt file that contains information about the Java classes derived from the information in the typelib. Make sure you use the method names given in this file for the interface you are using.

  3. Include the following lines near the top of your .java file created by the wizard:

          import mqoa.* ;
      import com.ms.com.Variant;

  4. Add the following method to create an MSMQ queue:

          public void CreateQueue()
         {
            Variant isTransactional;
            Variant isWorldReadable;
            IMSMQQueueInfo qinfo = (IMSMQQueueInfo)new MSMQQueueInfo();
            qinfo.putPathName(".\\qJava");
            isTransactional = new Variant();
            isTransactional.putBoolean(false);
            isWorldReadable = new Variant();
            isWorldReadable.putBoolean(false);
            qinfo.Create(isWorldReadable, isTransactional);
         }

Call the method CreateQueue() from Init() method and run MSMQ Explorer to verify that the queue has been created. If the queue already exists (if you run it twice), you will get a Java exception dialog box on the Web page.
