Install and Config

• Let’s assume you would like to run OpenJMS and Tomcat on the same server, eg myLocalServer
• Download OpenJMS from this page.
• Unzip the archive, extract it to C:\exe\openjms-0.7.7-beta-1
• Set an environment variable:set OPENJMS_HOME=C:\exe\openjms-0.7.7-beta-1
• Take the archive $OPENJMS_HOME/lib/openjms-tunnel-0.7.7-beta-1.war
  • copy it to: $CATALINA_HOME/webapps
  • rename it as: openjms-tunnel.war
• Edit OPENJMS_HOME/config/openjms.xml:
  • Before the ending tag</connectors>, add the block:

    <Connector scheme="http">
          <ConnectionFactories>
            <ConnectionFactory name="HTTPConnectionFactory"/>
          </ConnectionFactories>
     </Connector>

  • After the ending tag </connectors>, add the block:

    <HttpConfiguration port="3030" bindAll="true"
           webServerHost="myLocalServer" webServerPort="8080"
           servlet="/openjms-tunnel/tunnel"/>

• • Open Console² or an MS-DOS prompt
  • Go to $OPENJMS/examples/basic

  • Run: build. This will compile all the examples.

Check that OpenJMS is OK:

• • Edit jndi.properties,
    • Comment the property
      java.naming.provider.url

    • Add the line:

      java.naming.provider.url=tcp://myLocalServer:3035

  • Run:
    run Listener queue1

  • Open a second tab
  • Run:
    run Sender queue1 5

    • Expected output in the second tab:

      C:\exe\openjms-0.7.7-beta-1\examples\basic>run Sender queue1 5
      Using OPENJMS_HOME: ..\..
      Using JAVA_HOME:    C:\exe\beaweblo922\jdk150_10

Check that OpenJMS/Tomcat link is OK:

Manual Check

• • Stop the Listener instance launched sooner
  • Edit jndi.properties,
    • Comment the line
      java.naming.provider.url=tcp://myLocalServer:3035

    • Add the line:

      java.naming.provider.url=http://myLocalServer:8080

      (this is Tomcat manager URL)

  • Run: run Listener queue1

  • Open a second tab
  • Run:
    run Sender queue1 5

  • The expected output are the same as above.

GUI Check

• Stop the Listener instance launched sooner
• Ensure jndi.properties contains the line:

  java.naming.provider.url=http://myLocalServer:8080

• Run: $OPENJMS_HOME/bin/admin.bat

  • A Swing application should start.
  • Go to:
    Actions > Connections > Online

  • The queue queue1 should be followed by a ‘0’.
  • Run: run Sender queue1 50

    • Action > Refresh

    • The queue queue1 should be followed by a ’50’.
  • Run: run Listener queue1

    • Action > Refresh
