javax.servlet.jsp.PageContext无法解析为一种类型 [英] javax.servlet.jsp.PageContext cannot be resolved to a type

问题描述

我在jsp页面中看到以下错误-

I am seeing the below errors in my jsp page -

javax.servlet.jsp.PageContext cannot be resolved to a type
javax.servlet.jsp.JspException cannot be resolved to a type

我看到了有关此内容的帖子，并尝试了一些建议的方法. BalusC提供了很好的输入-不能同时使用JSTL1.2和Standard.jar.我做到了，它解决了一段时间的问题-但它再次出现.我不确定是否还有罐子碰撞.我已经将所有jar定义为Maven中的依赖项.以下是我指定的依赖项pom.xml-

I have seen a post on this and tried few things that were suggested. BalusC provided a great input - JSTL1.2 and Standard.jar must not be used together. I did this and it fixed the issue for sometime - but it is reappearing. I am not sure if I have any more jar collisions. I have defined all the jars as dependencies in Maven. The below are the dependencies that I have specified pom.xml -

推荐答案

您将需要在项目中导入JSP API，而servlet-api中没有这些API

You will need to import in your project the JSP APIs, which are not included in servlet-api

在我的项目中，解决方案是:

In my project, the solution is:

<dependency>
  <groupId>javax.servlet.jsp</groupId>
  <artifactId>jsp-api</artifactId>
  <version>2.1</version>
  <scope>provided</scope>
</dependency>
