To Run the Sample Application

1. Make the directory containing the HelloWorldmessageJNDI application your current directory, using one of the following commands, depending on how Message Queue was installed:

   • On IPS package-based installations:

     cd IMQ_HOME/examples/helloworld/helloworldmessagejndi
     

   • On Solaris SVR4 package-based installations:

     cd /usr/demo/imq/helloworld/helloworldmessagejndi
     

   • On Linux RPM package-based installations:

     cd /opt/sun/mq/examples/helloworld/helloworldmessagejndi
     

   You should find the file HelloWorldMessageJNDI.class present. (If you make changes to the application, you must recompile it using the procedure for compiling a client application given in the Message Queue Developer’s Guide for Java Clients.)

2. Set the CLASSPATH variable to include the current directory containing the file HelloWorldMessageJNDI.class, as well as the following .jar files that are included in the Message Queue product:

   jms.jar

   
   

   imq.jar

   
   

   jndi.jar

   
   

   fscontext.jar

   
   

   See the Message Queue Developer’s Guide for Java Clients for information on setting the CLASSPATH variable.

   ---

   Note –

   The file jndi.jar is bundled with JDK 1.4. You need not add this file to your CLASSPATH unless you are using an earlier version of the JDK.

   ---

3. Run the HelloWorldMessageJNDI application by executing one of the following commands (depending on the platform you’re using):

   • On Solaris or Linux:

        % java HelloWorldMessageJNDI file:///tmp
     

   • On Windows:

        java HelloWorldMessageJNDI
     

   If the application runs successfully, you should see the output shown in Example 2–1.
