Struts und Spring

[iuser]

Hallo,
ich versuche zur Zeit Spring in eine Struts-Anwendung zu integrieren. Dazu habe ich die vorhandene web.xml von dtd 2.2 auf

<!DOCTYPE web-app 
PUBLIC "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN" 
"http://java.sun.com/dtd/web-app_2_3.dtd">

geändert, um den Spring listener hinzuzufügen:

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

Sobald der listener-Tag in der web.xml steht, lädt der Context in Tomcat nicht mehr mit der Fehlermeldung:

Kann mir jemand bei der Fehleranalyse behilflich sein? Ich verstehe die Exception nicht.

Ich verwende java 1.4, Tomcat/4.1.36, Struts 1 und Spring 2.x

Gruß,

Hallo iuser,

auf dem Callstack taucht Digester auf. Das ist eine Bib, zum Einlesen von XML-Konfigurationsdateien, die Struts verwendet. Da ist ein Indiz, dass die Struts-XML-Konfig-Datei fehlerhaft ist.
