When you run the Tomcat 7.0 server in eclipse it gives a bunch of errors

Can't find a mistake. The tomcat7.0 server package stopped loading in eclipse. When creating a new project and a new connection, the HTML page is loaded, but the script does not want to load. This is what displays when loading the server.
