[GRASS-user] The tomcat shut down when encounter some error grass commond

[Sören Gebbert]

Hello maven,
i guess the problem  is located in your GrassMain.java line 200:

				if (ps.exitValue() != 0) {
					System.exit(ps.exitValue());
				}

AFAIK, the tomcat server uses a container to run the several servlet threads 
inside.
If you call from any servlet thread the System.exit() command, the server will 
be shutdown. 

Java doc of System.exit(): 
Terminates the currently running Java Virtual Machine.

Best regards
Soeren
