asyncsend example
-------------------
Description
-----------
This example illustrates how to write an application that uses a
JMS2.0 simplified API to send messages using async send and receive messages asynchronously
to/from topic. It also illustrates the use of jdk7 feature try-with-resources in JMS application.
Some basic info on this example:
- AsyncTopicProducerExample.class sends messages to the particular topic specified using asynchronous send.
When the mesage has been succesfully sent, the callback method onCompletion is invoked on an
MyCompletionListener object.
- AsyncTopicConsumerExample.class receives messages asynchronously from the particular topic specified
and displays the messages received.
- Start AsyncTopicConsumerExample before starting the producer AsyncTopicProducerExample
since a topic subscription will not receive messages which were sent to the topic before the subscription
was created.

Configuring the environment
---------------------------
To recompile or run this example, you need to set CLASSPATH
to include at least:
jms.jar
imq.jar
directory containing this example
A detailed guideline on configuring your environment and setting CLASSPATH
is found in the top-level README file of the examples (demo) directory of
the Message Queue installation (/examples/README) as well as in
the "Quick Start Tutorial" in the Oracle GlassFish(tm) Server Message Queue
Developer's Guide.
Building the example
--------------------
Run the following:
javac AsyncTopicConsumerExample.java
javac AsyncTopicProducerExample.java
Running the example
-------------------
Start a broker
imqbrokerd -tty
Run the following command first on one terminal:
java AsyncTopicConsumerExample []
Run the following command on another terminal:
java AsyncTopicProducerExample []
The output of AsyncTopicConsumerExample looks like this:
java AsyncTopicConsumerExample topic1 20
Topic name is topic1
Created jms context successfully
Created topic successfully
