I modified the quartz.properties file in the quartz.jar. Open it with winzip extract change
and rezip/jar. Evidently the one in the quartz.jar is the default - I am not sure where to
put a quartz.properties file - I tried the usual location WEB-INF/classes to no avail.

I which file did you add "QuartzScheduler.setSchedulerThreadClassLoader()"?
Where did you add the association "org.quartz.scheduler.useClassLoaderOfInitializer"?
Where is this environment variable "useClassLoaderOfInitializer"?

Subject: RE: Quartz Struts Plugin Errors
I was having a similar issue where the classpath for Quartz was based on my Tomcat home. For
version 1.0.7 I added the property for specifying the class loader as in the release notes
state below and all was good. For some reason in 1.1.2 I did not have to add the class loader
property. I do not see where they added some default behavior so I am not sure why 1.1.2
behaves differently. The properties file is in the quartz.jar.
It would be great if the Quartz Struts Plug In supported setting the quartz properties from
the XML file. Does anyone know where the quartz program looks for the property file prior
to using the one included in the JAR?
10- Added QuartzScheduler.setSchedulerThreadClassLoader() - and
associated "org.quartz.scheduler.useClassLoaderOfInitializer"
property for StdSchedulerFactory.
If you're using Quartz in an application server environment
(or servlet container) and experience class loading issues, you
may wish to try setting the "useClassLoaderOfInitializer" property
to true. This instructs Quartz to "steal" the class loader off of the
thread that is initializing Quartz, and use that class loader for the
loading of Job classes. For instance if you initialize Quartz with a
startup-servlet (in you web-app) then Quartz could grab the class
loader off of the thread that is initializing the web-app - thus
providing access to the jobs classes that are defined in jars only
accessible by the web-app's class loader.

The QuartzConfig object was created to facilitate using XML to
configure Quartz.
Ultimately, the problem is that the call made in Digester's
ObjectCreateRule to instantiate a QuartzConfig is using a ClassLoader
that can't find the class.
Looking into the Digester code, it appears that Digester defaults to
using the same ClassLoader that loaded it -- does JBoss use Digester
itself? That could explain the problem.
http://jakarta.apache.org/commons/digester/xref/org/apache/commons/digester/ObjectCreateRule.html#252
http://jakarta.apache.org/commons/digester/xref/org/apache/commons/digester/Digester.html#405
Odds are good that if you snuck into SchedulerBuilder and added
digester.setUseContextClassLoader(true)
at line 197 or so, you might solve the problem.
http://demo.jgsullivan.com/quartz/maven/xref/com/jgsullivan/quartz/SchedulerBuilder.html#199
You can download the source at
http://demo.jgsullivan.com/quartz/maven/download.html
If that works, let us know and we can update the distribution.

Is Digester being loaded from the webapp classpath?
