Goals

"Mobile Datacommunication" is a chapter in the book called "Java praxisnah - Profitieren Sie von Programmierprofis".

JMS Communication Test is a source code package used in the book. JMS Communication Test shows how to set up an error respecting JMS communication on a low-quality, high-latency bearer (e.g. GPRS connection).

Installation

Major software products involved:

• Joram version 3.0.1 (the libs from joram are needed)
• JDK version 1.4.x
• Ant version 1.5.1

It is assumed that JDK and Ant software are already installed and ready to run on your system. Joram needs to be unpacked and the libraries contained in the joram distribution have to be copied to the project directory - see below. Joram is selected as the JMS implementation because of it's a powerful freeware without licensing problems coming as a binary and source package.

• Unpack Joram distribution.
• Copy all jar-files from directory ".\joram-3.0.1\lib" to the example project directory structure into directory "JMSTest/lib".
• Now the system should be able to compile the examples without error messages.

You will need these jar-files for compilation:

• jms.jar
• joram.jar

You will need these additional files for execution:

• mom.jar
• ol_util_log_wrp_log4j.jar
• log4j.jar
• xerces.jar

Compile

[Note: Before you may compile the project without errors you have to install the joram jar-files into directory lib of the example project. See Installation section for further information!]

• Change to the project root directory.
• Type "ant" into your command line tool. The default target for ant is the "deploy" target. This will compile all necessary sources.
• Compilation should succeed without any problems.
• If you encounter problems regarding ant or java please check your installation of ant and / or the java jdk.

Execution

• To execute the example you have to open three different command line environments.
  One will be used to execute the JoRAM JMS server.
  One will be used to execute the sending client.
  The third will be used to execute the receiving client.
• Change to the first command line and type
  startadmin
  This will configure the JMS server for this example.
• To start the JMS server type
  startjoram
  into the same command line.
  Screen output should look like this:
  >startjoram
  AgentServer#0 started.
   
• Switch to the second command line and type
  startsender
  Screen output should look like this:
  >startsender
  Start JMS Sender ...

• Switch to the last command line and type
  startreceiver
  Screen output should look like this:
  >startreceiver
  Start JMS Receiver ...
