我剛開始使用Eclipse Servlet，當嘗試使用Eclipse Servlet時出現此錯誤在服務器上運行一個動態的Web項目：Java EE Eclipse Servlet Tomcat 7錯誤：名爲[...]的Servlet都映射到不允許的url-pattern

關於鏈接錯誤：
The servlets named [action_edit_profile] and [ro.lsrs.couchfriends.controllers.ActionEditProfile] are both mapped to the url-pattern [/action_edit_profile] which is not permitted，web.xml文件被如此設定（在給定的誤差例如用於小服務程序）：<servlet> <servlet-name>action_edit_profile</servlet-name> <servlet-class>ro.lsrs.couchfriends.controllers.ActionEditProfile</servlet-class> </servlet> <servlet-mapping> <servlet-name>action_edit_profile</servlet-name> <url-pattern>/action_edit_profile</url-pattern> </servlet-mapping>EDIT：就this問題可能的重複，它不是同樣的問題。我的問題是URL衝突（映射被設置在xml和java類中）。相反，this問題幫助我解決了這個問題。
看看「由......引起的」行。看到一個提到URI模式？ – nitind
感謝@nitind，這的確是問題所在。下次我會知道更好地從控制檯發現錯誤。我的答案中提到了類似的問題已經得到解決。 – dannychris37
