When running as a Windows Service, the Application will be unable to show its Dialog.
So this sample application is not very interesting.
We can however do a few tests to verify
that the Wrapper acts as a Windows Service correctly.
| You will see the output: |
wrapper | <Your App> installed.
|
Once your application is installed as a service,
we will want to start it.
| You will see the output: |
<Your App> service is starting.
<Your App> service was started successfully.
|
The service can be uninstalled by executing the following command:
Uninstall<Your App>-NT.bat
|
| If the service is running, you will see the output: |
wrapper | Service is running. Stopping it...
wrapper | Waiting to stop...
wrapper | <Your App> stopped.
wrapper | <Your App> removed.
|
If you look at the contents of logs/wrapper.log,
you will see output very similar to that of the console.
Except this time,
the start message informs you that the application is being started as a Service.

Here are the results of several more actions that can take place on Windows Service:
|
A log entry is made when the user logs out, but the service is unaffected.
| wrapper.log |
wrapper | 2001/12/06 17:39:39 | --> Wrapper Started as Service
wrapper | 2001/12/06 17:39:40 | Launching a JVM...
jvm 1 | 2001/12/06 17:39:40 | Initializing...
jvm 1 | 2001/12/06 17:39:40 | Wrapper (Version 3.x.x)
jvm 1 | 2001/12/06 17:39:40 |
jvm 1 | 2001/12/06 17:39:41 | start()
wrapper | 2001/12/06 17:40:07 | User logged out. Ignored.
jvm 1 | 2001/12/06 17:40:07 | controlEvent(202)
|
|
|
This will result in a logout signal followed by a shutdown signal.
The service will be shutdown gracefully and then come back after the machine restarts.
