Re: tomcat restart ptoblem
Is it installed as a Windows Service? Is the Service set to start automatically? If it isn't, you know what to do! If it is but it isn't starting successfully, try the following:- a) try to Start the service manually; b) if it fails, examine the Windows Event log, as well as the various Tomcat logs.

I'm running Tomcat as an init.d System V service on Linux. This means I can't write a simple script to restart it - the restart has to be done as root (although Tomcat runs as a user called tomcat). My startup script already does the work of moving jarfiles and our native library to their correct locations. So I've decided that automatic restart is in the 'too hard' category: instead I'll include in the webapp the means for an administrator to determine whether the deployment is up to date (fresh jarfiles in the shared/lib folder etc). It'll then be a manual administration task to restart Tomcat when required. It won't happen often.

Re: tomcat restart?
Rick,
Actually, I believe it might be possible. Ugly, but possible. Using
Runtime.getRuntime() to get the current runtime, you can then actually
make a call to a shell command. You could call a batch file that would
shut down the server and then restart it. What I don't know is if the
newly exec'd process gets taken down with tomcat... if so, you could
have the shell program that you call start a new process that would
not be associated with the existing one (in windows you can use the
command 'start' in a batch file to start a separate process... someone
else will no doubt supply the *nix equivalent).
For example in the servlet use:
Runtime.getRuntime().exec("call_bounce_tomcat.bat");
Then call_bounce_tomcat.bat would contain:
start /SEPERATE bounce_tomcat.bat
bounce_tomcat.bat would actually do the work of restarting tomcat
(specifically how, I'll let you worry about ;).
Sorry I don't have more time to flesh everything out, but take a look
and see if that'll get you where you need to go.
Cheers,
Patrick

RE: tomcat restart?
This is not possible as even if it could be shut down then the servlet will no longer exist to restart it. The only way would be for the servlet to notify some external process that the tomcat needs to be restarted and the external process will do the stopping and starting.

RE: tomcat restart problem
Hi, Umm, maybe ;) But more likely, do this: - Send a SIGQUIT to the tomcat process so that it generates a thread dump. - Kill the process using the kill command. - Inspect the thread dump to look for deadlocks, etc. - Back up your logs - Start tomcat.
