RES: JVM' sperm size always increase after hot deploy to tomcat 5.0.28
Thank you all It's good to know that we're not alone...but since we used to have workable 'hot deploy' others pre-J2EE App Servers our customers will insist with that - maybe we'll have to reconsider other App Server as our main Open-Source production environment option.

No hot deploy possible for ROOT context app?
Hi all, I've been working on setting up an application in the root context, meaning I configure it via this in server.xml: This works fine, and my application gets loaded properly at tomcat start-up. I just want to make sure I'm not missing any tricks. This approach seems to eliminate the possibility of hot deploy, right? Meaning, any time I change my war file, I need to restart tomcat? Next I will try an expanded war and reloadable classes, but any comments would be appreciated. This is 4.1.29 under jboss.

Cláudio CarvalhoHi, Does anybody know how to make a deploy on a running tomcat (hot deploy)? When I try do it using the Tomcat Web Application Manager, I got the following message FAIL - Application already exists at path /myapplicationThanks.
RE: Hot deploy?
Howdy,
Hot deployment as you describe exists and is enabled by default, i.e.
you don't have to do anything but drop the WAR into the webapps
directory. This is true for tomcat 4 as well as tomcat 5, for which you
can stop waiting as it's available already.

Hot deploy?
Hi all,
I'm very much looking forward to Tomcat 5.x! Reading the docs, I can't tell
if Tomcat 5.0 offers JBoss-style hot-deployment of WARs or not. By "JBoss-style",
I mean all I have to do is drop a new WAR into a deployment directory, and it will
get picked up and redeployed. Section 4 of the User's Guide ("Deployment") implies
that this is possible, using something called the host's "autodeploy" attribute.
However, Section 3 ("First Webapp") seems to have an exhaustive list of all
possible deployment methods, and automatic hot deployment is not mentioned.
Does such hot deployment exist? Or is the only option to use the deployment
Ant tasks?
Thanks,
Chris

Hi Leonardo, You can redeploy a webapp through the admin or manager applications. I have not tested myself, but I think that if you configure a persistent session manager (you can find more info on this in the configuration reference), active sessions should be stored before the webapp shutdown, and reloaded upong restarting it.

Hi, Chris, Thank you very much for your help. It works now. I am not aware of the change, because in the real work, I deploy my apps outside of Tomcat, so I have to do all the configurations, mappings ...

Running tomcat 4.1 installed from RPM things look fine, but for some
reason or another I cannot get hot (re)deployment to work. Copying a
war file into /var/tomcat4/webapps makes it jus lay there.
I mean this worked yesterday :-( but I cannot imagine what I have done

I see that there is the following code in server.xml:
Is this what it should look like? Other points to look into?

What's a "context config file"? It's a separate XML file that contains just the element, and any nested elements such as JNDI resource definitions.

Hot Deploy?
Hello Folks, Is 'hot deploy' something that is being planned for Tomcat 4.0. I use Tomcat with JBoss and do not use an EAR file to deploy to the combination ... instead deploy a server side jar for JBoss and the compiled classes for Tomcat. If I stick to the current method of deployment will Tomcat 4.0 support automatic loading of modified classes? Currently I get ClassCastExceptions if I recompile classes - cause the classloaders get confused I guess! .menon

Yes you are right, I think why he wanted to edit web.xml was to map the servlet to a url pattern. i.e. /myservlet/ ..bip
Re: Hot Deploy.
Why do you need to edit web.xml, whenever you add a servlet? I do not think there is anything editable that will help in adding servlets in the web.xml file. If you add a new servlet in an existing context, it should be automatically being recognised and run. Otherwise, if you want to add it in a new context, you need to change the server.xml, add the servlet and stop/start tomcat.

There is no HotDeploy, however you can set a to be reloadable which means that servlet classes is reloaded if changed.

Just a comment... If Tomcat can be shutdown via a port, why can't it be told to read the new config using the same way? Restarting doesn't have to be done by shutting down the JVM; just read the new config, and apply the new values internally. Oki
