Tomcat 4 restart command?

[Jonathan Eric Miller <je...@uchicago.edu>]

I'm wondering if in Tomcat 4 there is a "restart" command that you can use
to restart it rather than having to "stop" and "start" it using startup and
shutdown scripts?

The problem that I have is that it takes time for it to startup and
shutdown, especially when you have SSL enabled. So, a restart command would
be nice. Or, if it printed out messages like it does in Tomcat 3.x where as
each listening port becomes active (i.e. first port 8080 for HTTP, then
later when HTTPS is available and the SecureRandom has been generated), it
prints out a message to the screen. This way you know when Tomcat is fully
started or stopped. Otherwise, the scripts just return you back to the UNIX
prompt before it's actually started up or shutdown and you don't know
exactly when that process is complete.

I guess a restart command isn't really that important although it would be
nice. I like the messages that are displayed in Tomcat 3.x better though. I
like knowing exactly when the ports are ready for use.

Thanks for the info. Actually, I just enabled the "reloadable" option on my
Context (development server). So, as long as that works reliably, I should
have to restart my server far less often.

Thanks, Jon

FYI anytime you or anyone writes an email like this, I drop it into a "docs"
folder, and if it spawns an idea for something, I have an email i put notes
in.  E.g. someone wrote "i got tomcat standalone running, now what?" which i
put a to-do of creating an image or doc on how to read through the docs.

You know it's done when you see the second "Starting service xxxxx" line
in $CATALINA_HOME/logs/catalina.out.

There's no restart command for the whole server, but there is a convenient
way to restart a particular webapp (say, because you just updated it).

Prerequisite:  set up a user in your conf/tomcat-users.xml file that has a
role named "manager".  It doesn't matter which user and password it is
(Tomcat will only check for the presence of this role).

Now, assume you want to force the web app at context path "/examples" to
reload.  Simply go to a browser and type:

  http://localhost:8080/manager/reload?path=/examples

The first time you do this, you will be challenged for the username and
password you have entered.  But, after that, you can just hit "reload" to
resubmit the same command again.

This stuff will be covered in a (soon to be written, I promise :-) HOWTO
document about the Manager web app.  In the mean time, consult the source
code of the Manager servelt (org.apache.catalina.servlets.ManagerServlet)
for all the things it can do.
