[Wrapper-user] [Wrapper+JWS] Problem with NT service

[<did...@vo...>]

Hi,

I'm using the Java Service Wrapper to launch a Java Web Start application as a NT Service (W2000). To do so, I followed the instructions given here : 
<http://www.seajug.org/vqwiki/jsp/Wiki?JavaWebStartTips>

My application runs fine, but in the Service Panel, my service is showed as 'not running'.
I investigated a bit and found out that :
- the wrapper launches a JVM for JWS
- JWS launches another JVM for my application
- the JWS JVM ends normally and my application still runs fine
- the wrapper ends and the service is showed as 'not running'
- my application is still running as a 'javaw.exe' process in the windows task manager.

The fact that the service is not showed as 'running' is confusing. The admin may want to start my application again and again.
So, is there a way to avoid this behavior?

To illustrate this, here is the output for a console execution : 

C:\bin\wrapper>Wrapper.exe -c wrapper.conf
