The Talend Runtime Container is based on Apache Karaf. Karaf Wrapper (for service wrapper) makes it possible to install the Talend Runtime Container as a Windows Service. Likewise, the scripts shipped with Karaf also make it very easy to install the Talend Runtime Container as a daemon process on Unix systems.
To install Talend Runtime Container as a service, you first have to install the wrapper, which is an optional feature, and you can then install the service.
The Wrapper correctly handles "user log outs" under Windows, service dependencies, and the ability to run services which interact with the desktop.
