automatic shutdown from servlet.init() that is load-on-startup

[Brett Porter <bp...@f2network.com.au>]

Hi,

I saw a message a while back on this, but don't remember a solution and 
failed to find it in the archives.

I am looking to shutdown Tomcat 4 if a set of initialisation functions 
fail. These functions are in the init() method of a servlet that is set 
to load on startup (the first).

Throwing a ServletException doesn't stop Tomcat, and I tried calling 
Bootstrap.main( new String[] { "stop" } ); but that didn't unbind it 
from the port either (it didn't give me any log messages either, but it 
did prevent anything executing after that :)

Thanks,
Brett Porter

Whoops!  This is for Tomcat 3.2.3.

Sorry.

The way to shutdown tomcat is to use the class

org.apache.tomcat.task.StopTomcat

which sends a shutdown message to the ajp12 port.

An example of it's usage is in

Tomcat.java
(src/share/org/apache/tomcat/startup)

hope this helps

I realise this isn't very well-behaved, but any others will probably be 
dealing with the same problems. At this point in time there is only one 
web application.

Perhaps there is another solution - eg send an email on failure and get 
an administrator to check in on the problem.

Cheers,

Do you mean a webapp should be able to stop the
appserver tomcat ?
If this is what you wanted, then will other webapps be

happy with this ?
