Reloadable context

Hi ,

I am using tomcat-5.5.12 and would like it to auto reload my web app as soon as it detects the change  of the web app class(es). That's why i've turned on the "reloadable" attribute of the Context element that defines my web app:

<Context path="/myWebApp" docBase="/home/testUser/myWebApp"  reloadable="true" crossContext="true" allowLinking="true" />

It does not seem to work. When I recompile one of myWebApp's servlets tomcat detects the change but then throws a warning:

May 17, 2006 7:33:41 AM org.apache.catalina.core.StandardContext reload
INFO: Reloading this Context has started
May 17, 2006 7:34:01 AM org.apache.catalina.core.ApplicationDispatcher invoke
WARNING: Servlet invoker is currently unavailable

So I've got to restart tomcat to get my change deployed.

Any idea on what I am missing?


Thanks a lot.


Alex.

I found this article useful for clustering tomcats.

Subject: help, windows tomcat multiple instances

Hi,

I am trying to connect Apache webserver with multiple instances of tomcat.
I added following line in httpd.conf of apache and apahce is starting 
fine and forwarding requests to tomcat.   Some how tomcat multiple 
instances are not active.

LoadModule jk_module modules/mod_jk.so
NameVirtualHost 130.88.1.52
<VirtualHost 130.88.1.52>
    ServerAdmin Bharathi.Kattamuri@manchester.ac.uk
    DocumentRoot C:\opt\tomcat_instance1\webapps\servlets-examples
    ServerName www.xyz.com:80
    ErrorLog logs/dummy-host.example.com-error_log
    CustomLog logs/dummy-host.example.com-access_log common
    JkMount /servlets-examples/* worker1   
</VirtualHost>

I am using windows and starting Tomcat as a service.  how to start 
tomcat multiple instances?  Any help is appreciated.

with regards,
Bharathi.

No idea on what you are missing.
you try reloading the application from tomcat manager application. that 
works for me.
Atleast you save the restart trouble.
