Restarting TOMCAT

[Hariharasubramanian Ranganathan]

Hi All,

I'm using currently using T3.2.3 under Windows 2000 / Linux boxes.  Since I
deployed the webserver on a remote machine, I tried to do some management
tasks through browser itself.  So I write some servlets / JSPs to show the
list of files, download files and upload files.

Let say I disabled the auto-reload feature and I have to update my context
to a newer version.  What I'll do is just upload the .WAR file to
...../webapps folder and I'll restart Tomcat *remotely*.  This is my plan.
I succeed in all other cases except restarting Tomcat.

First I tried a batch file (tcrestart.bat) which stops (tomcat stop) and
starts (tomcat start) the tomcat.  I'll run this command using
Runtime.exec() and Process.  But when tomcat shuts down, it won't start
again. I can't guess why?

Second I tried to run the same through a seperate thread.  i.e. I'll start a
thread which inturn do the same in first point.  This time too, I failed.

Finally I go through the tomcat source code and found the easier way to stop
and start tomcat. Now I write the code as

    import java.util.*;
    import org.apache.tomcat.startup.Tomcat;
    public class TomcatRestart implements Runnable {
        public TomcatRestart() {
            Thread t = new Thread( this);
            t.start();
        }

        public void run() {
            // Stop Tomcat
            //
            String[] stopargs = new String[1];
            stopargs[0] = "-stop";
            Tomcat.main( stopargs);                    // ---> Here tomcat
stops.

            // Start Tomcat
            //
            String startargs = new String[] {};
            Tomcat.main( startargs);                    // ---> here, it's
not starting.
        }
    }

I don't know where I'm making mistakes?

Please help me in this case or give me some suggestions, how to implement
this feature.

Thanks,
