JAVA下幾個問題

1、Server MyEclipse Tomcat v8.5 was unable to start within 45 seconds. If the server requires more time

打開Workspace文件路徑，而後修改以下圖所示「servers.xml」 文件，而後修改「start-timeout」爲一個較長時間1000.

 

 2、JSP頁面報錯：The superclass "javax.servlet.http.HttpServlet" was not found on the Java Build Path

右鍵項目名稱，選擇Java Build Path. 而後點擊「Add Liberary」, 選擇「Server Runtimes」.
