Re: [Springframework-developer] Example classes needed

[<tri...@tr...>]

Lars,

This might be a WebLogic specific issue - I just saw similar error when I
deployed my app in WebLogic 8.1.

I will try to research this in more detail later on today or tomorrow.  In the
meantime try this in your web.xml

<servlet>
<servlet-name>cwxRootContext</servlet-name> 
<servlet-class>com.interface21.web.context.ContextLoaderServlet</servlet-class>
<load-on-startup>1</load-on-startup>
</servlet>

<servlet>
<servlet-name>cwx</servlet-name>
<servlet-class>com.interface21.web.servlet.DispatcherServlet</servlet-class>
<load-on-startup>2</load-on-startup>
</servlet>
