Hi Olli, according to the tutorial (at section: Learning by example: your first Struts application), there is no mention of struts-config.xml yet. However, the web.xml has a reference to it. That could be the cause of problem that Tomcat could not create a web application called "registeruser". I still have a same problem after creating the struts-config.xml.
