hot deploying jars, compiling without relaunch ?

[oceatoon]

Hi ofbizians

we are trying to set up hot deploying for our jars, has anybody done this ?

is it possible to get Tomcat reload jars dynamically after compile like he
usually does when set up as a external server(not included in the
applications jar) ?
we've tried playing around with the shared folder, and some of the catalina
configurations...but without success.

Best Regards

Thx

Tomcat has an admin application that allows for webapp load/unloading.  
Look in the tomcat docs that came with your install.

Please be aware that doing this always causes a memory leak.

I never did this reloading in a production environment, we would usually
have multiple instances of an app server and patch one, restart each
one.  Because we have multiple instances running, we never had downtime,
although users did lose their session data.

Hi Phillip,

We are gearing up to run in a load balanced environment and based on what
you stated, I'm assuming that you are using sticky sessions for the users?
If so, what are you using for your load balancer and dealing with sticky SSL
traffic?

Thanks,

John

did you manage to do this with Tomcat inside Ofbiz ?
if yes, could you please share the procedure ?
we tried
<property name="apps-context-reloadable" value="false"/>
and manage to recompile but the newly compiled jar isn't used :(

Thx for the help
Tibor

we tried loading catalina as a container , then when we recompile we get
>>> Cached loader got a known bad class name

I'm sure we're close to the goal,
can someone please enlighten us on this .

Yes, we are doing sticky sessions for users.  This is part of mod_jk and
tomcat configuration.
