✔ WingS (mit Eclipse, Tomcat): java.io.IOException: org.wings.plaf.css.CSSLookAndFeel

[Grober]

Hallo,

ich benutze WinXP, EasyEclipse 1.2.2.2, Tomcat 6.0.14, jdk1.6.0 und wingS 3.0. Ich bin Anfänger mit Tomcat und wingS und will ein Projekt auf wingS umstellen.

Wenn ich dieses Projekt "händisch" als war-File in Tomcat deploye, dann läuft es. Wenn ich es aber in Eclipse einrichte, dann erhalte ich den folgenden Fehler beim Aufruf mit Tomcat: javax.servlet.ServletException: javax.servlet.ServletException: java.io.IOException: org.wings.plaf.css.CSSLookAndFeel

Da komme ich nicht weiter. Der Fehler läßt sich auch mit Google so gar nicht auftreiben.

Hier noch die vollständige Fehlermeldung:

note The full stack trace of the root cause is available in the Apache Tomcat/6.0.14 logs.

Und hier noch, was ich von tomcat kriege:
