我在jsp文件中出现错误(在X行上),但这似乎都是正确的。
<%@ page language="java" contentType="text/html; charset=UTF-8" pageEncoding="UTF-8"%> <!DOCTYPE html"> <html> <head> <meta http-equiv="Content-Type" content="text/html; charset=UTF-8"> <title>Insert title here</title> </head> <body> <form method="GET" X action="${pageContext.request.contextPath}/docreatetask"> <table> <tr> <td>Task</td> <td><input name="task" type="text" /></td> </tr> <tr> <td>Description</td> <td><input name="description" type="textarea" /></td> </tr> <tr> <td>Deadline</td> <td><input name="description" type= /></td> </tr> <tr> <td></td> X <td><input name="Create new task" type="submit" /></td> </tr> </table> </form> </body>
**Error 1** javax.servlet.ServletException can not be resolved **Error 2** javax.servlet.http can not be resolved
会是什么呢?是否在任何地方使用ServletException或javax.servlet.http?
对于第一个错误(java.servlet.http can not be resolved to a type),您需要将servlet- api.jar文件放入`classpath:
java.servlet.http can not be resolved to a type
servlet- api.jar
为此,请按照下列步骤操作:
servlet-api.jar
对于第二个错误:( javax.servlet.ServletException can not be resolved):
javax.servlet.ServletException can not be resolved
