Hi
Try Load on startup in web.xml configuration for Quartz .
I have done the same and have good results
The configuration is as PER QUARTZ API
<servlet>
<servlet-name>
QuartzInitializer
</servlet-name>
<display-name>
Quartz Initializer Servlet
</display-name>
<servlet-class>
org.quartz.ee.servlet.QuartzInitializerServlet
</servlet-class>
<load-on-startup>
1
</load-on-startup>
<init-param>
<param-name>config-file</param-name>
<param-value>/some/path/my_quartz.properties</param-value>
</init-param>
<init-param>
<param-name>shutdown-on-unload</param-name>
<param-value>true</param-value>
</init-param>
<init-param>
<param-name>start-scheduler-on-load</param-name>
<param-value>true</param-value>
</init-param>
</servlet>
With regards
karthik

Actually, now that Elli points that out...

The Host XXX.com doesn't have an appBase defined, so it might be using
the default - which may mean that you're deploying the app twice, once
as the ROOT application, and once under it's actual name.
You can check this by requesting: http://www.XXX.com/xxx, where "xxx" is
the actual name of your app.
Either way, setting the Context in server.xml is _strongly_ discouraged.
You should:
1. set an appBase attribute in the XXX.com Host definition.
2. Remove the Context definition from server.xml
3. Remove the path & docBase attributes from the Context definition
4. Add a file "META-INF/context.xml" containing the Context definition
to your web application.
5. rename your application directory "ROOT".
... and then let us know if the problem still occurs.
