初始化部署web專案常見錯誤
1、The superclass "javax.servlet.http.HttpServlet" was not found on the Java Build Path
新建的web專案,專案所有jsp頁面報錯如下
1)在出現此錯誤的專案上右鍵-->Build Path --> Configure Build Path
2)點選右邊的 ADD Library->server Runtime
3)選擇部署好的tomcat,即可錯誤消失。
4)如錯誤繼續存在,右鍵專案點選Refresh
5)如繼續出現錯誤,找到tomcat的安裝目錄的lib下,
或者在專案的環境下是否有servlet-api.jar包,如沒有可手動新增後再重新配置。
(之前試過百度下載的tomcat沒有servlet-api.jar)
2、There are no resources that can be added or removed from the server
專案新增不進對應的servers
專案上右鍵-->Build Path --> Configure Build Path
進入Project Facets 選中Dynamic Web Module和java
