RE: Webapp with Adminstrative Console
From: chuanjiang lo [mailto:[EMAIL PROTECTED] Subject: Re: Webapp with Adminstrative Console Is there any articles i can look at to implement the servlet watch for changes to the .ini file? You can set a WatchedResource tag inside the Context element for your webapp; changing the target of that should trigger a reload of the app. Look here for doc: http://tomcat.apache.org/tomcat-5.5-doc/config/context.html#Nested%20Com ponents I don't think i am able to redeploy the app, since the adminstrator console changing the .ini file of the application that is currently running on tomcat.. Should be able to do it by sending a delayed refresh of the console page back to the client, and also forwarding a request to the html-manager app to do the redeploy. A bit of a kludge, but it can probably be made to work. Shouldn't be needed with WatchedResource. But better just to process the updated .ini file without redeploying the app, if possible. - Chuck THIS COMMUNICATION MAY CONTAIN CONFIDENTIAL AND/OR OTHERWISE PROPRIETARY MATERIAL and is thus for use only by the intended recipient.

Seems a bit of overkill to take the whole server down for just that. You could also just redeploy the app when needed, which can be accomplished programmatically or via the Tomcat manager or html-manager webapps.

Together with the web application, there is an adminstrator console that allows user to change the settings of the config file . I realize that if the config file is changed, i would need to restart Tomcat as such my servlet would read in the changed settings. I'd redesign the app. Of course you'll need time and source code for this ;-) Since you're using a servlet to read config files, just map it to some URL and call it to reload configuration. You could also use JMX to change configuration at runtime. Spring has nice JMX support. -- Mikolaj Rydzewski [EMAIL PROTECTED]http://ceti.pl/~miki/ PGP KeyID: 8b12ab02 There are three kinds of people: men, women and unix. smime.p7s Description: S/MIME Cryptographic Signature

Looks like the WatchedResource tag is the easiest solution of all but JMX seems interesting and i can learn something new but is it possible to do without Spring?

Yes, Tomcat uses JMX internally to manage itself. Look at the source code for the admin app, for example. Looking at the LambdaProbe code might be another way to learn how it's used with Tomcat. - Chuck THIS COMMUNICATION MAY CONTAIN CONFIDENTIAL AND/OR OTHERWISE PROPRIETARY MATERIAL and is thus for use only by the intended recipient.
