Tomcat shuts down on closing jar

Question

I made a java web application that calls a main method from a jar file i included as a WebAppLibraries and when this main calls system.exit to terminate it shuts down also the web app closing tomcat. How can avoid to shut down the web app closing only the execution of that main method?

Answer 1

By not calling System.exit(). Instead, call the appropriate API for shutting down web-apps for your container, which is container-specific. System.exit() isn't it. See the Javadoc. It's for shutting down entire JVMs, such as servlet containers.
