Tomcat中的独立应用程序

Question

I have a simple java class that i want to run programmatically. This is basically a video player. It is also deployed along with my web application in tomcat. This should run upon a click on a particular link. From controller, here's how I run it

new Thread(() -> { VideoPlayer.main(new String[]{}); }).start();

It is working fine. But every time I close the Video player, tomcat is also terminated. Any ideas on how to correct this?

Answer 1

Your GUI probably calls System.exit when you close it. That'll take-down Tomcat since they are both running in the same JVM. Find and remove the System.exit and you'll find things work-out better for you.

Also note that it doesn't make any sense for a web application to launch a video player. Think about it: once the web application is no longer running on your own personal development workstation, the video will be played on the server where there isn't anyone to watch it. The server probably won't even have a monitor attached to it. Most likely, you'll get a whole series of exceptions from the video player telling you it couldn't initialize itself because there isn't any graphics environment in which to start.
