Hello, I have a problem with an aplication type .war, when I deploy with jboss I get this error: ERROR [HelloWorld] Error configurando escuchador de aplicacion de clase org.springframework.web.context.ContextLoaderListener java.lang.ClassNotFoundException: or.springframework.web.context.ContextLoaderListener it seems that jboss not take the ContextLoaderListener class, but this class is inside the spring-web.jar library and this library is in WEF-INF/lib of my app.war. I don't know why server not found it. I prove putting in archive pom.xml of server the following: org.springframework spring 2.5.5 org.springframework spring-web 2.5.5 but it ocurrs same error. Can anyone help me? Thanks, and regards PD: The app.war is one example of HelloWorld of AnayaMultimedia, but in the example of the book there are missing libraries of spring, and there is to modify it.
