Odd, because I observer no such behavior (just tried it on 6.0.26, Windows Vista), and it's certainly not documented to work that way. Will try it on Linux when I get a chance. - Chuck THIS COMMUNICATION MAY CONTAIN CONFIDENTIAL AND/OR OTHERWISE PROPRIETARY MATERIAL and is thus for use only by the intended recipient.

My experience is that if a .class file has been loaded by the WebappClassLoader and it gets updated, the webapp is reloaded. The same is true of a .class file loaded from a .jar file in WEB-INF/classes: if the .jar file changes, the webapp is auto-reloaded. I can observe this behavior in both 5.5(.25/.26/.27/.28) and 6.0(.26). - -chris -BEGIN PGP SIGNATURE- Version: GnuPG v1.4.10 (MingW32) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org/ iEYEARECAAYFAkwFETIACgkQ9CaO5/Lv0PDEhQCeJLBfvpfIjF/a3NEYeCRRegkX O/kAn0R05Ze3qyUrqHQTsTCFRlE+B3CL =SYs8 -END PGP SIGNATURE- - To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org

Re: "Gracefull" restart of tomcat
Hello *, Manager application is not installed on the system. You mentioned that it depends on the configuration. Configuration of tomcat which is used is delivered by OS. In the /etc/tomcat5/base/Catalina/localhost is only relevant XML file. which contains path and docbase where tomcat can find servlets and other jar files. War files are not used. Only jar files with web.xml files. 2010/5/31 Pid > On 31/05/2010 11:40, Petr Hracek wrote: > > Dear users, > > > > I would like to ask you on the some thing which regards to the > application > > deployment and > > neccessary restart of tomcat5. > > Tomcat 5?

You can update/replace the war file. This may trigger an application restart, depending on your configuration. The manager application can also be used to update and restart web applications. p signature.asc Description: OpenPGP digital signature
Re: "Gracefull" restart of tomcat
I am not sure if you had looked into deploy redeploy feature of tomcat. Probably, that is what you are looking for Perry On Mon, May 31, 2010 at 4:10 PM, Petr Hracek wrote: > Dear users, > > I would like to ask you on the some thing which regards to the application > deployment and > neccessary restart of tomcat5. > > When I am some servlet which are run under tomcat and I have build up the > new jar files for my application > is it enought to copy this file to my location without neccessary restart > of > tomcat? > > Is there any "gracefull" restart of tomcat like in apache2? > > Is there any mechanishm how to update servlets when tomcat is already > running > so that tomcat 5 will not be restarted and new servlets will be loaded? > > Thank you in advance > > -- > Best Regards / S pozdravem > Petr Hracek > -- Pankaj Tiwari
"Gracefull" restart of tomcat
Dear users, I would like to ask you on the some thing which regards to the application deployment and neccessary restart of tomcat5. When I am some servlet which are run under tomcat and I have build up the new jar files for my application is it enought to copy this file to my location without neccessary restart of tomcat? Is there any "gracefull" restart of tomcat like in apache2? Is there any mechanishm how to update servlets when tomcat is already running so that tomcat 5 will not be restarted and new servlets will be loaded? Thank you in advance -- Best Regards / S pozdravem Petr Hracek
