This example is a basic HelloWorld program showing a JFrame. This application is packaged as an executable jar file. Please follow these steps.

1. Load the HelloWorld.ejp file in execJ and look over the settings.
2. Go to the build tab to build the project.
3. The application is built as an exe in the build directory.
4. You can start the application from within execJ or navigate to the build directory in windows explorer to double click it.

This example demonstrates how to create a windows service java application. Please follow these steps.

1. Load the ServiceDemo.ejp file and look over the settings.
2. Go to the build tab to build the project.
3. The application is built as an exe in the build directory.
4. Click "Add & Start Service" which will add your exe as a service and start it. Alternatively, you can open a command prompt and execute a command like

   myexe.exe -addService -noauto -startService

5. In the exe's directory, an execJservice.txt log file is written to.
6. Open your Windows Services in the Control Panel. Try pausing and resuming the service from there and watch the logs detect the events.
7. You can then click "Stop & Delete Service" which will terminate the service and remove it from the service list.

Note: If using Windows Vista, you will need to change your build directory to something not in Program Files due to new security procedures preventing the writing to that directory.
