Can you post the bit of the web.xml where you register the ContextLoaderListener? It should look something like:

Code:

	<servlet>
		<servlet-name>context</servlet-name>
		<servlet-class>org.springframework.web.context.ContextLoaderServlet</servlet-class>
		<load-on-startup>1</load-on-startup>
	</servlet>

or for servlet 2.4 (preferred method):

Code:

	<listener>
		<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
	</listener>

???why?

**katentim** · May 12th, 2005, 05:03 AM

Your web.xml doesn't appear to be valid. The version="2.3" should be version="2.4"
