JMS Step 2 - Using the QueueSend.java Sample Program to Send a Message to a JMS Queue

This post is the second in a series of JMS articles which demonstrate how to use JMS queues in a SOA context.

In the previous post
JMS Step 1 - How to Create a Simple JMS Queue in Weblogic Server 11g
I showed you how to create a JMS queue and its dependent objects in WebLogic Server. In this article, we will use a sample program to write a message to that queue. Please review the previous post if you have not created those objects yet, as they will be required later in this example. The previous post also includes useful background information and links to the Oracle documentation for additional research.

The following post in this series will show how to read the message from the queue again.

1. Source code

The following java code will be used to write a message to the JMS queue. It is based on a sample program provided with the WebLogic Server installation. The sample is not installed by default, but needs to be installed manually using the WebLogic Server Custom Installation option, together with many, other useful samples. You can either copy-paste the following code into your editor, or install all the samples.

The knowledge base article in My Oracle Support:

How To Install WebLogic Server and JMS Samples in WLS 10.3.x (Doc ID 1499719.1)

describes how to install the samples.

2. How to Use This Class

2.1 From the file system on UNIX/Linux

Log in to a machine with a WebLogic installation and create a directory to contain the source and code matching the package name, e.g. $HOME/examples/jms/queue. Copy the above QueueSend.java file to this directory.

  1. Set the CLASSPATH and environment to match the WebLogic server environment.
    Go to $MIDDLEWARE_HOME/user_projects/domains/base_domain/bin and execute

    . ./setDomainEnv.sh
  2. Collect the following information required to run the script:
  • The JNDI name of a JMS queue to use
    In the Weblogic server console > Services > Messaging > JMS Modules > (Module name, e.g. TestJMSModule) > (JMS queue name, e.g. TestJMSQueue). Select the queue and note its JNDI name,
    e.g. jms/TestJMSQueue
  • The JNDI name of a connection factory to connect to the queue
    Follow the same path as above to get the connection factory for the above queue, e.g. TestConnectionFactory and its JNDI name
    e.g. jms/TestConnectionFactory
  • The URL and port of the WebLogic server running the above queue
    Check the JMS server for the above queue and the managed server it is targeted to, for example soa_server1. Now find the port this managed server is listening on, by looking at its entry under Environment > Servers in the WLS console,
    e.g. 8001
    The URL for the server to be given to the QueueSend program in this example will therefore be t3://host.domain:8001
    e.g. t3://jbevans-lx.de.oracle.com:8001
  1. Edit QueueSend.java and enter the above queue name and connection factory respectively under

public final static String JMS_FACTORY=" jms/TestConnectionFactory ";

public final static String QUEUE=" jms/TestJMSQueue ";


  1. Compile QueueSend.java using
    javac QueueSend.java
  2. Go to the source's top-level directory and execute it using
    java examples.jms.queue.QueueSend t3://jbevans-lx.de.oracle.com:8001
  3. This will prompt for a text input or "quit" to end.
  4. In the WLS console, go to the queue and select Monitoring to confirm that a new message was written to the queue.

2.2 From JDeveloper

  1. Create a new application in JDeveloper, called, for example JMSTests.
  2. When prompted for a project name, enter QueueSend and select Java as the technology

  3. Default Package = examples.jms.queue (but you can enter anything here as you will overwrite it in the code later).
    Leave the other values at their defaults.

  4. Press Finish
  5. Create a new Java class called QueueSend and use the default values

    This will create a file called QueueSend.java.
  6. Open QueueSend.java, if it is not already open and replace all its contents with the QueueSend java code listed above

  7. Some lines might have warnings due to unfound objects.
    These are due to missing libraries in the JDeveloper project.

  8. Add the following libraries to the JDeveloper project:
  1. right-click the QueueSend project in the navigation menu and select Libraries and Classpath , then Add JAR/Directory
  2. Go to the folder containing the JDeveloper installation and find/choose the file javax.jms_1.1.1.jar , e.g. at D:\oracle\jdev11116\modules\javax.jms_1.1.1.jar

    Do the same for the weblogic.jar file located, for example in D:\oracle\jdev11116\wlserver_10.3\server\lib\weblogic.jar

  1. Now you should be able to compile the project, for example by selecting the Make or Rebuild icons

  2. If you try to execute the project, you will get a usage message, as it requires a parameter pointing to the WLS installation containing the JMS queue, for example t3://jbevans-lx.de.oracle.com:8001 . You can automatically pass this parameter to the program from JDeveloper by editing the project's Run/Debug/Profile. Select the project properties, select Run/Debug/Profile and edit the Default run configuration

    and add the connection parameter to the Program Arguments field

    If you execute it again, you will see that it has passed the parameter to the start command

  3. If you get a ClassNotFoundException for the class weblogic.jndi.WLInitialContextFactory , then check that the weblogic.jar file was correctly added to the project in one of the earlier steps above.

Set the values of JMS_FACTORY and QUEUE the same way as described above in the description of how to use this from a Linux file system, i.e.

public final static String JMS_FACTORY=" jms/TestConnectionFactory ";

public final static String QUEUE=" jms/TestJMSQueue ";


  1. You need to make one more change to the project. If you execute it now, it will prompt for the payload for the JMS message, but you won't be able to enter it by default in JDeveloper. You need to enable program input for the project first.

    Select the project's properties, then Tool Settings, then check the Allow Program Input checkbox at the bottom and Save.

  2. Now when you execute the project, you will get a text entry field at the bottom into which you can enter the payload. You can enter multiple messages until you enter "quit", which will cause the program to stop.

The following screen shot shows the TestJMSQueue's Monitoring page, after a message was sent to the queue:

This concludes the sample. In the following post I will show you how to read the message from the queue again.

    Fantastic code.......

  • Sreenivas Thursday, November 2, 2017
    Thanks. It worked like a charm. But did small code change as message Quit also coming as one message in Queue messages. So changed the code snippet as below. Please check and suggest if any modification needed.

    System.out.print("Enter message ("quit" to quit): n");
    line = msgStream.readLine();
    if (line != null && line.trim().length() != 0) {
    quitNow = true;
    System.out.println("JMS Message Sent: "+line+"n");
    } while (! quitNow);

    Great, amazing, THANKS

    After upgrading to WLS 12c when sending a message to SOA end point throws the following

    javax.jms.JMSSecurityException: Access denied to resource: type=, application=PS_RHINT2_Mod_BT_CLIENT, destinationType=queue, resource=INST1_DSPS_SRC_PS_DS_No
    tify_Message, action=send
    Caused by: javax.jms.JMSException: DD UOO failover not allowed for member PS_RHINT2_Mod_BT_CLIENT!SAFID_PS_RHINT2_BT_ENT_CLIENT!INST1
    _DSPS_SRC_PS_DS_Notify_Message@SAFAgent_BT_CLIENT which is not available
    at weblogic.utils.StackTraceDisabled.unknownMethod()

    Whereas (not upgraded environemnt) 11g send s the message properly w/o any errors. This from PeopleSoft environment.

    Unable to localize the problem :(
