If your IDE produces an error like javax.servlet.jsp cannot be resolved to a type you shuold include the jsp-api dependency to solve that:
<dependency>
<groupId>javax.servlet</groupId>
<artifactId>jsp-api</artifactId>
<version>2.0</version>
<scope>provided</scope>
</dependency>
Make sure that the scope is provided, because the servlet container that we use to run our project will provide this dependency. This is because the jsp-api is not required when compiling your project, it is only needed when you run the project (aka it is a runtime dependency).
For me, this error came up in STS (which is a variation of Eclipse), but you can expect it in other IDEs as well.
