Probleme mit struts - ActionServlet

[slider7777]

Hallo,

Ich habe eine kleine Web Anwendung mit struts geschrieben (in Eclipse). Jedoch findet Tomcat anscheinend die Klasse ActionServlet nicht, diese ist jedoch in den Libraries vorhanden...

der Fehler:
java.lang.ClassNotFoundException: org.apache.struts.action.ActionServlet

das packet org.apache.struts.action sowie die Klasse sind vorhanden....

hier mal die web.xml:

<?xml version="1.0" encoding="UTF-8"?>

	</welcome-file-list>
</web-app>

struts-config.xml:

<struts-config>


	<form-beans>

		<form-bean name="thema" type="beans.BeanThema" />
	
	</form-beans>
	
	
	<action
	  name="forum"
      path="/start"
      scope="request"
      type="actionhandler.ForumAction"
      validate="false">
      <forward name="success" path="/abc.jsp" />
      <forward name="failure" path="/error.jsp" />
    </action>
	
	
	<action
	  name="thema"
      path="/thema"
      scope="request"
      type="actionhandler.ThemaAction"
      validate="false">
      <forward name="success" path="/thread.jsp" />
      <forward name="failure" path="/index.jsp" />
    </action>
	
	
	
	
</struts-config>

In welchen Libraries liegt denn deine struts.jar?

 

[slider7777]

hallo,

ich habe eben alle vorhandenen *.jar files von struts in das Projekt eingebunden. das oben genannte Packet liegt glaub in struts-core.jar

 

[HLX]

Komisch. Liegen die jars in WEB-INF/lib?

 

[slider7777]

ich benütze eclipse, habe also ein sogenanntes dynamic web project angelegt, die eingebundenen packete liegen alle unter library

 

[HLX]

Aha, ich nehme an im Java Build Path. Liegen sie dort einfach nur so, oder als Web App Libraries.

Falls es keine Web App Libraries sind, enferne die Jars aus den Libraries und kopiere sie ins Verzeichnis WEB-INF/lib. Nur so erfährt auch der Tomcat von den Bibliotheken. Sonst werden sie nur für´s Kompilieren verwendet.
