HTTP 404-Die angeforderte Ressource (/ /) ist nicht verfügbar - Tomcat 6
Erstellte ich ein kleines "Dynamic Web Project" in eclipse und versuchen zum anzeigen/Bearbeiten/erstellen und löschen Sie meine Daten base Objekte. Der tomcat-server läuft. Aber ich bekomme einen HTTP Status 404-Fehler : Die angeforderte Ressource (/TestDynWeb/) ist nicht verfügbar(http://localhost:8010/TestDynWeb). Ich würde gerne zeigen, alle meine code-Dateien. Vielleicht haben Sie eine Idee, was falsch ist.

Wahrscheinlich haben Sie nicht die Bereitstellung der Anwendung auf dem Tomcat-Server. Müssen Sie rechts klicken Sie auf den server in der Server-view und drücken Sie "Hinzufügen und Entfernen" und fügen Sie dort Ihr Projekt auf dem server.

gehen Sie auf project rechts-klicken und check-Bereitstellung Baugruppe. Überprüfen Sie, ob der Ordner mit web.xml ist richtig aufgenommen oder nicht. es kann sein, dass Sie möglicherweise konfiguriert haben web.xml in verschiedenen Ordner und im deployment-assembly Webcontent-Ordner Hinzugefügt.

Überprüfen Sie, dass auf "Deployment Montagesätze" es ist Ihr WebContent-Ordner. Wenn nicht, fügen Sie es.
