graceful windows command line shutdown

I can hit ctrl-c with the best of them. When I do this, I see a bunch of messages about things gone bad and then a window pops up wanting to know if I want to notify microsoft about my system problems.

I would like to make a batch file that I could put in my project called bounce.bat. It would tell tomcat to gracefully shutdown and block until tomcat was all done. Then it would call "ant deploy" - where I would pretty much delete everything in the tomcat webapps directory, then drop a fresh war file. Then it would start tomcat back up.

Is this too much to ask?

Here's one that I use.
It does it the opposit way from what you just described (the ant script calls the shell/batch script)
Like yourself, I feel more comfortable with a complete shutdown of Tomcat.
Since I'm doing that, I never needed to install the ANT tasks for deploying.

This script probably does more than what you want so you'll have to weed out what's junk to you:

It:
  • Deletes the current copy of the application
  • Pulls the entire project from CVS to the scratch directory
  • Does some string replacement (version numbers, connection strings, etc)
  • Compiles all the Java classes (by calling nested build scripts)
  • Jars up all the class files and deletes the source (this removes the temptation to make a fix on the build server instead of doing in the developer's environment and checking it into CVS)
  • Packs everything into a war file.
  • Calls a shell script that restarts Tocmat

  • CD tomcat/bin
    ./shutdown.sh
    ./startup.sh
  • Sleeps for a while, giving tomcat a chance to wake up and deploy the new war file.
  • Moves some non-shipping files into directories within the app.
  • Says "done"


  • sample.build.xml
    I'm sure an ANT guru could show me better ways to do some of this stuff but it does what I need.


    At least one of the tags was a problem for the forum software and it would have been too time consuming to figure out which so I provided a link to it instead.


    For a winders box you just need to change the ./startup.sh to startup etc.
    Or... If you're running Tomcat as a service, you can use:
    net stop TOMCAT_SERVICE_NAME
    net start TOMCAT_SERVICE_NAME

    Or, if you're running Tomcat as a service.


    You can get the service name by looking in the properties window from the services screen. I just looked on one of our windows boxes and it's "Tomcat5"

    Graceful would be a stretch but it is thorough.

    I have a question about running shutdown.bat immediately followed by startup.bat
    Typically my Tomcat takes quite a while to go through the shutdown routine so I always wait till it vanishes from the processes list. Is it safe to start a new instance with startup.bat while the old one is still shutting down?

    I do it all the time with the shell scripts in Linix.
    The new one runs under a different process.
    I can't say for sure with Windows.

    If it is a problem, you could always run the shutdown script, then build the project before calling startup.
    Or, use Ant's sleep task to insure that there is some time between the two.
     
    I agree. Here's the link: http://aspose.com/file-tools
