Getting Started :

Source files

Following are the source files generated,

SimpleClass.java
SimpleClassMBean.java
StandardJmxAgent.java

Compilation

To compile the source files go to WebNMS/JavaAgent/examples/jmx/timer directory in the command prompt and type,

compile *.java [Windows] or
sh compile sh *.java [Linux/Solaris]

This will compile the source files in the respective directory.

Running the Agent

To start the agent go to WebNMS/JavaAgent/examples/jmx/timer directory in the command prompt and

1. Use run.bat or run.sh

          By default,
                  (a) RMI registry service will be started at port 1099
                  (b) CORBA naming service will be started at port 1050

2. The file StandardJmxAgent.java has the code to instantiate the timer.

3. The notifications to be sent should be added to the Timer .

4. The timer checks the notifications and sends the notifications.

5. In this example, one notification is added so that it occurs thrice for a specific period of time.

Testing

The notification details are printed on the console.
