Chciałbym utworzyć i uruchomić prostą aplikację RESTful na moim komputerze. Używam języka programowania Java, na Eclipse Helios IDE, z serwerem Apache Tomcat 7, w systemie operacyjnym Microsoft Windows Xp.

Próbowałem powtórzyć tę samą proceduręten samouczek (od 3 do 3.4 kroków) na moim komputerze, ale to nie działa.

Oto co zrobiłem:

stworzył projekt dynamiczny w Eclipse z ustawieniami Apache Tomcat 7

umieść w projekcie moje pliki jar i Jersey i jsr311-api-1.0\WEB-INF\lib\ informator

skopiowałem części kodu ze strony internetowej do mojego projektu

kliknij prawym przyciskiem myszy projekt, kliknij „Uruchom jako -> Uruchom na serwerze”

próbowałem dotrzeć dohttp://localhost:8080/de.vogella.jersey.first/rest/hello

Ale oto co widzę:

Dlaczego to nie działa? Co zrobiłem źle? Czemu?

Wielkie dzięki!
