Cannot Resolve Method [JSP]

Add your application server libraries to the module dependencies with Provided scope: http://www.jetbrains.com/idea/webhelp/configuring-module-dependencies-and-libraries.html .

For Tomcat you need TOMCAT_HOME\lib\jsp-api.jar file.

I also experience this issue. The provided solution above is not informative at all. Can you provide more sound solution please?

I finally managed to fix it by deleting the .Intellij setting (in my case, C:\Users\username\.IntellijIdea2017.2) and i have to again set the jdk and application server (tomcat) once again just like in the previous setting. This is a very annoying way to solve since i cannot find any other solution at all.

I also experienced this issue. I solved adding the following maven dependecy in the pom.xml (following the tip of Serge Baranov)

<dependency>
    <groupId>javax.servlet.jsp</groupId>
    <artifactId>javax.servlet.jsp-api</artifactId>
    <version>2.3.1</version>
    <scope>provided</scope>
</dependency>
