Hi,
  I'm trying to use my own ClassLoader for my Web-Application. I
google a long time and find that the Loader component in the Context
component could help me to replace the ClassLoader of my web application
(subclassing WebappClassLoader).

  In the first place, I tried to use the default parameters for the
Loader component. My context file
($CATALINA_HOME/conf/engine/host/context.xml) was

<Context path="/app"
          reloadable="true"
          docBase="C:/apacheTest/test/app"
          workDir="C:/apacheTest/test/app/work" />

and my application were loading and working properly.

When I change to

<Context path="/app"
          reloadable="true"
          docBase="C:/apacheTest/test/app"
          workDir="C:/apacheTest/test/app/work" >
<Loader
          className="org.apache.catalina.loader.WebappLoader"
          delegate="false"
         
loaderClass="org.apache.catalina.loader.WebappClassLoader" />
</Context>


I always got this error in the console :

2007-03-01 16:37:19 org.apache.catalina.core.StandardContext start
GRAVE: Error listenerStart
2007-03-01 16:37:19 org.apache.catalina.core.StandardContext start
GRAVE: Erreur de d?marrage du contexte [/app] suite aux erreurs pr?c?dentes

I googled and searched for information with this error and googled for
example using Loader component without any success.

How can I use the Loader component properly?

I'm using Tomcat 5.5.20 and tried it only under Windows.

Thank you in advance for your time.
