To Deploy and Run the Clients for the Synchronous Receive Example Using NetBeans IDE

1. Deploy and run the Producer example:

   1. Right-click the producer project and select Properties.

   2. Select Run from the Categories tree.

   3. In the Arguments field, type the following:

      queue 3

   4. Click OK.

   5. Right-click the project and select Run.

      The output of the program looks like this (along with some application client container output):

      Destination type is queue Sending message: This is message 1 from producer Sending message: This is message 2 from producer Sending message: This is message 3 from producer

      The messages are now in the queue, waiting to be received.

      ---

      Note –

      When you run an application client, there is usually a noticeable delay between the first two application client container messages and the remainder of the output.

      ---

2. Now deploy and run the SynchConsumer example:

   1. Right-click the synchconsumer project and select Properties.

   2. Select Run from the Categories tree.

   3. In the Arguments field, type the following:

      queue

   4. Click OK.

   5. Right-click the project and select Run.

      The output of the program looks like this (along with some application client container output):

      Destination type is queue Reading message: This is message 1 from producer Reading message: This is message 2 from producer Reading message: This is message 3 from producer

3. Now try running the programs in the opposite order. Right-click the synchconsumer project and select Run.

   The Output pane displays the destination type and then appears to hang, waiting for messages.

4. Right-click the producer project and select Run.

   The Output pane shows the output of both programs, in two different tabs.

5. Now run the Producer example using a topic instead of a queue.

   1. Right-click the producer project and select Properties.

   2. Select Run from the Categories tree.

   3. In the Arguments field, type the following:

      topic 3

   4. Click OK.

   5. Right-click the project and select Run.

      The output looks like this (along with some application client container output):

      Destination type is topic Sending message: This is message 1 from producer Sending message: This is message 2 from producer Sending message: This is message 3 from producer

6. Now run the SynchConsumer example using the topic.

   1. Right-click the synchconsumer project and select Properties.

   2. Select Run from the Categories tree.

   3. In the Arguments field, type the following:

      topic

   4. Click OK.

   5. Right-click the project and select Run.

      The result, however, is different. Because you are using a topic, messages that were sent before you started the consumer cannot be received. (See Publish/Subscribe Messaging Domain, for details.) Instead of receiving the messages, the program appears to hang.

7. Run the Producer example again. Right-click the producer project and select Run.

   Now the SynchConsumer example receives the messages:

   Destination type is topic Reading message: This is message 1 from producer Reading message: This is message 2 from producer Reading message: This is message 3 from producer
