Restarting Tomcat via Ant
Is there any way I can restart a remote Tomcat using an Ant task? I googled a while and even found some sources but they were about HttpClient abusing the manager application and exec calling the batches via net shares. Anything better than the ManagerApp abuse? thx in advance -- Sent from the Tomcat - User forum at Nabble.com: http://www.nabble.com/Restarting-Tomcat-via-Ant-t207149.html#a577719

project name=Learning default=reloadContext basedir=.
target name=reloadContext
get dest=stop.txt
src=http://localhost:8080/manager/stop?path=/Learning;
username=adminUserName password=adminPassword/
loadfile property=STOPOUTPUT

/target
/project
The only thing you need to change is the
http://localhost:8080/manager/stop?path=/Learning; of it ...
So if you want to do for www.manik.com for context /Learning
Then it will be http://www.manik.com/manager/stop?path=/Learning and
if you want to do for www.guru.com for context /Learning
Then it will be http://www.guru.com/manager/stop?path=/Learning
Hope you find this useful

Re: Viewing Web Resource Updates without Restarting Tomcat
I wasn't aware of Tomcat doing any caching of JSP pages... could be wrong, but are you sure it's Tomcat doing the caching, not a browser or proxy server? You may want to look at the Expires, Cache-Control etc. headers that are being sent with your pages. You can clear the compiled classes in the work dir if you want to force JSPs to be recompiled, but I've always found that Tomcat detects new JSPs itself (even with the Context set with reloadable=false). Anything in WEB-INF/classes or WEB-INF/lib (basically anything picked up by the classloader) requires a restart or reload for changes to be detected.

Agreed, and if you have any session information and the session can't be (for whatever reason) be de/serialized, it would indeed be a very bad idea to restart tomcat.

Redeployment of a webapp without restarting tomcat
Hi I am using tomcat 5.0.X, and have the following serlvet.xml file: /etc/tomcat5/Catalina/localhost/Servlet.xml Context path= docBase=/home/chrisp/Servlet.war reloadable=true/ I would like the webapp to be unloaded and reloaded when I make changes to the war file. autoDeploy and unpackWARs are both true in the server.xml Currently, when tomcat starts, it upacks Servlet.war to /var/lib/tomcat5/webapps/ROOT. If I update Servlet.xml, the webapp is reloaded, but not unpacked again, even if the war file has changed. Is there a way to get the war to be unpacked again if it has changed. I don't have the manager webapp installed, and do not want to install it. Are there any other ways around my problem? -- Chris Picton [EMAIL PROTECTED] Tangent Systems - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

Re: new Host without restarting Tomcat
I may be incorrect, but in all I have read, the server.xml is only read once, during Tomcat startup. This is the reason for the context.xml fragment files which can be read and loaded without a restart. So the answer is it can't be done at this point.

Re: new Host without restarting Tomcat
Thank you for your response. server.xml is read only once, but, with the Tomcat Admin Tool, we can increase this config and save it. So, I think the only (perhaps?) missing feature to do the creation of the Host is the ability to declare the privileged=true within the Context Manager. I'll try to declare a bug for this. Thank you.

RE: restarting tomcat
Yes, you need to reload the webapp for changes to be recognised, although for caching reasons, some browsers may not recognise the change to a JSP straightaway. JSP's are compiled on-the-fly and compiled in the work directory as you mentioned. I use the ant build tool for this, I'm not sure what other alternatives are available. This is my understanding from looking at the log files. This is a typical entry when I reload a webapp: 2004-03-30 13:29:08 StandardContext[/gfapp]: Reloading this Context has started 2004-03-30 13:29:08 WebappLoader[/gfapp]: Deploying class repositories to work directory /usr/local/tomcat/work/Standalone/www.thegoldenfreeway.com/gfapp 2004-03-30 13:29:08 WebappLoader[/gfapp]: Deploy class files /WEB-INF/classes to /home/webapps/gfapp/WEB-INF/classes 2004-03-30 13:29:08 WebappLoader[/gfapp]: Reloading checks are enabled for this Context 2004-03-30 13:29:08 StandardWrapper[/gfapp:default]: Loading container servlet default 2004-03-30 13:29:08 StandardWrapper[/gfapp:invoker]: Loading container servlet invoker 2004-03-30 13:29:08 StandardManager[/gfapp]: Seeding random number generator class java.security.SecureRandom 2004-03-30 13:29:08 StandardManager[/gfapp]: Seeding of random number generator has been completed 2004-03-30 13:29:08 StandardContext[/gfapp]: Reloading this Context is completed 2004-03-30 13:30:08 StandardContext[/gfapp]: Reloading this Context has started 2004-03-30 13:30:08 StandardWrapper[/gfapp:jsp]: Waiting for 1 instance(s) to be deallocated 2004-03-30 13:30:09 StandardManager[/gfapp]: Seeding random number generator class java.security.SecureRandom 2004-03-30 13:30:09 StandardManager[/gfapp]: Seeding of random number generator has been completed 2004-03-30 13:30:09 ApplicationDispatcher[/gfapp] Allocate exception for servlet jsp On Wed, 2004-03-31 at 07:06, Rob Ross wrote: I'm not talking about *restarting* Tomcat, I'm talking about *reloading* a web app. You're right, you don't have to shut down the Tomcat server to restart a webapp, you can just reload it, either manually by using the http manager interface, or automatically by setting the reloadable attribute in the config file to true.

Re: restarting tomcat
Changed items can be re-loaded on the fly because of dynamic classloading. Every JSP instance lives in its own classloader. When a jsp source file is changed, the JSP servlet recognizes the change and recompiles the JSP. Once the JSP is translated to a new .java (and .class file) - the class file is read in as a new class under a new classloader and the old classloader is discarded. Because the of the creation and destruction(well ... the absence of referenceing) of classloaders - you can reload the same class (jsp class name) mulitple times in the life of a single JVM instance. When it comes to servlets - they aren't loaded by an extra classloader. In that case - you need to reload the *entire* webapp which does the above but for all classes/jars in the WEB-INF directory. The dynamic classloading abilities are (one of)the primary reasons why tomcat ignores the CLASSPATH variable on startup. Because once the system classloader loads a class - its there forever - no dynamic reloading allowed!

Restarting Apache without restarting Tomcat
Hi, I noticed if I restart Apache without restarting Tomcat, *sometimes* the request doesn't get sent properly. It's a rather weird error though. From the tomcat debug, I can seem that the program got to the handleLogin() method in the login class. But the user will not be able to login. The database side is not the issue here. Restarting Tomcat fixed the above behaviour. So my question is: why *sometimes* restarting Apache without restarting Tomcat works, but not all the time? Does the order matter? I can always restart Tomcat without restarting Apache. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

That's normal, in my experience.

Re: lag when restarting tomcat
Howdy, You can reduce startup time by eliminating unneeded applications. In production servers, I hardly ever leave anything but the webapp itself: I remove the admin, manager, docs, webdav, examples, ROOT contexts. Things that affect shutdown include your custom finalizers, if any. Similarly, destroy() methods in servlets, filters, and various shutdown methods in listeners can take time to invoke and execute. If you're really annoyed by this and care enough to contribute code, why don't you profile tomcat startup to see where CPU time is spent, and then suggest patches? ;) Yoav Shapira --- Euan Guttridge [EMAIL PROTECTED] wrote: If I bounce tomcat via the /bin/shutdown.sh /bin/startup.sh scripts it takes at least 20 seconds until it responds again.

If you are using the mod_jk from 3.2.x, then this is true. Any more recent version allows you to restart Tomcat independently of Apache. You can even simply upgrade mod_jk, and continue to use TC 3.2.x if you want. softspt [EMAIL PROTECTED] wrote in message news:[EMAIL PROTECTED] Protective Marking: UNCLASSIFIED Is it possible to set up Tomcat so that it services JSP requests for Apache, yet can be restarted independently?

Re: Restarting Tomcat without restarting Apache
You can start/stop each independently. I do it all the time. You may encounter errors in Apache's logs, if it is in the middle of trying to satisfy a request to Tomcat, but Tomcat is restarted before the request can complete. The cleanest way to do this, for stops, is: stop Apache, then stop Tomcat. For starts: start Tomcat, then start Apache. that way, requests are not handled until Apache is up. But doing it this way is not required. The only time restarting Tomcat requires an Apache restart is if you are using the ApacheConfig classes in server.xml to auto-generate mod_jk configuration information for Apache. Since the mod_jk.conf file gets created every time Tomcat is started, you would need to restart Apache for it to pick up any changes to that file.

Server.xml Reload without Restarting Tomcat
Hi, I think I asked this question before but I didn't get a definitive answer. I want to be able to reload my server.xml file on the fly after making modifications to it. I want to know whether this is possible on Tomcat (Stand-alone) for version 4.1.x.

Re: Shutting down and restarting Tomcat
Hi Peter, try this batch file (startAndStop.bat): echo off echo. echo Calling startup echo. call startup.bat echo. echo Started echo. pause echo. echo Calling shutdown echo. call shutdown.bat echo. echo Shut down echo. pause startAndStop.bat The pause command is necessary, because it takes Tomcat a few seconds to shut down. The next call will be done after you'll have pressed any key. This script is an endless loop because it calls itself in the end. To end it press Ctrl-C or the X-Button in the upper right corner.

As far as I know, there isn't one. You can only use PAUSE which waits for user input before continuing. That won't help you, though, if you're sitting at your keyboard tapping the spacebar or Enter key as soon as you see the pause prompt. You could try installing something like Cygwin and writing a shell script...then you'd have access to the sleep command.

Re: Shutting down and restarting Tomcat
Hi, What is the command for setting the delay in a Windows batch file? I downloaded something called UnxUtils.zip from the web (can't find where from at the moment). Amongst other Unix goodies this includes sleep.exe. It is a package of standalone binaries and you need install/use only those you need, unlike Cygwin or Perl which are pretty massive. With sleep.exe on your path you could then put a line like sleep 2 in your batchfile to wait 2 seconds before proceeding. Regards, John.

Updating files without restarting Tomcat
I am using Tomcat 4. I have a number of properties files in the WEB-INF/classes directory.

Re: Updating files without restarting Tomcat
I've actually had problems with the reloadable attribute. I think it may be broken. You may try the HTMLManager application, which allows you to monitor, start, stop and reload your various webapps. You'll need to modify the conf/tomcat-users.xml and webapps/manager/WEB-INF/web.xml; instructions are in the comments, and here's the link to the HOW-TO: http://jakarta.apache.org/tomcat/tomcat-4.0-doc/manager-howto.html - Alfred Douglas, Rory wrote: You can specify the attribute reloadable=true in the context element for your web-application (in server.xml) This will, however, watch all files for changes.

RE: restarting tomcat programatically
Howdy, If your own webapp is running on the tomcat instance you're trying to restart, then HUH? ;) One VM can always restart another, as others have proposed. So you can have a command line program, shell scripts, another webapp running on another tomcat instance, etc. Alternatively, look at how JBoss manages its embedded tomcat ;) You'll have to do a bit more work, and need to know some JMX MBeans stuff.

RE: Updating files without restarting Tomcat
Hi, In order for tomcat to reload your files, you have to add reloadable=true to your application context in server.xml. However, this will cause tomcat to restart each time one of yout classes has been changed or one of the jars in WEB-INF/lib. Not only, it'll effect performance, but creating a new class loader isn't so obvious, and might cause problems (If you use jni, for example). good luck, Tamir -Original Message- From: cbarnes [mailto:[EMAIL PROTECTED]] Sent: Wednesday, May 01, 2002 12:16 PM To: Tomcat Users List Subject: Updating files without restarting Tomcat I am using Tomcat 4.

Re: restarting Tomcat 4
It works fine if you wait long enough between calling the stop and start script, but not if you write a restart script which calls catalina.sh start and immediately after, catalina.sh stop, because then there's no delay between the two, and tomcat doesn't have the time to shutdown before you try (and fail) to restart it. In my case, I need to wait 10 seconds between doing a shutdown and a startup, but this varies depending on the number of webapps you have (in the case of the original poster, it's 40 seconds), so I agree with him there should be a more elegant way to restart the server.

RE: how to get changes to web.xml without restarting tomcat
Hi, -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]] Sent: Thursday, January 31, 2002 6:17 PM To: [EMAIL PROTECTED] Subject: how to get changes to web.xml without restarting tomcat All, My dilemma as I understand it is this. Tomcat is run at root level, requiring restarts of both Tomcat and Apache to be performed by the system administrator. For changes to take effect in web.xml (so far as I can tell) Tomcat must be restarted. This means, bugging the system administrator to restart Tomcat and then restart Apache. Anytime an init-param changes I have to go through the sysadmin. As I recently inherited a bunch of servlets, and they have migrated from windows to Linux and from JWS to Tomcat, as you can imagine there are many changes to such parameters. Is there a way to get around this at all? Reloading class files is already transparent to the sysadmin, either through a reloadable context, or the manager application, but the web.xml changes are bringing me down. Do I have to write a custom servlet? It seems to me that Tomcat should allow for something basic like this. Yeap, I expected reloading to read and parse web.xml every time. But it doesn't. So, I have to start/stop application from manager application. Using HTMLManagerServlet its still pretty easy, just two clicks. Thanks to any who take the time to try to help.
