I've found out that perhaps I needed to update my web.xml file. The file looks like this now: <?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE web-app PUBLIC "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN" "http://java.sun.com/dtd/web-app_2_3.dtd";> <web-app> <display-name>Nye metoder Application</display-name> <description>application.</description> <context-param> <param-name>contextConfigLocation</param-name> <param-value>WEB-INF/applicationContext.xml /WEB-INF/applicationContext-ejb.xml</param-value> </context-param> <filter> <filter-name>MyFacesExtensionsFilter</filter-name> <filter-class>org.apache.myfaces.webapp.filter.ExtensionsFilter </filter-class> <init-param> <param-name>maxFileSize</param-name> <param-value>100k</param-value> <description>Set the size limit for uploaded files.

I get an error when I start the server also: Both RI and myfaces jsf are on your classpath. Could this have anything to do with the setter method error? What do I have to do to find the method?
