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

Question

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

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 -

Answer 1

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

In my project, the solution is:

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