The following page the error occurs during execution of a web application in JBoss:

I think that has something to do with web.xml descriptor.

Contents of web.xml:

  | <?xml version="1.0" encoding="ISO-8859-1"?>
  | 
  | <!DOCTYPE web-app
  |     PUBLIC "-//Sun Microsystems, Inc.//DTD Web Application 2.2//EN"
  |     "http://java.sun.com/j2ee/dtds/web-app_2_2.dtd">
  | 
  | <web-app>
  | 	<servlet>
  | 		<servlet-name>XXXServlet</servlet-name>
  | 		<servlet-class>XXXServlet</servlet-class>
  | 	</servlet>
  | 	<servlet-mapping>
  | 		<servlet-name>XXXServlet</servlet-name>
  | 		<url-pattern>/XXXServlet</url-pattern>
  | 	</servlet-mapping>
  | 	<welcome-file-list>
  | 		<welcome-file>principal.jsp</welcome-file>
  | 	</welcome-file-list>
  | 
  | 	<resource-ref>
  | 		...
  | 	</resource-ref>
  | 
  | 	<session-config>
  | 		<session-timeout>30</session-timeout>
  | 	</session-config>
  | 
  | </web-app>
  | 

And to ensure that the XXXServlet.class is at the correct location, is displayed below of the output of command:
jar -tf <folder-jboss_deploy>/.war


  | ~$ jar -tf <folder-jboss_deploy>/xxx.war
  | ...
  | META-INF/ejb-jar.xml                                                                  
  | META-INF/jboss.xml                                                                    
  | WEB-INF/classes/XXXServlet.class                                                      
  | WEB-INF/classes/com/jspsmart/upload/File.class                                        
  | WEB-INF/classes/com/jspsmart/upload/File.class.hacked

  | WEB-INF/classes/com/jspsmart/upload/Files.class
  | ...
  | 

Someone could help me this problem?

Now, thanks!
