You need to add the runtime libraries from your application server.

For example:

Go to project properties. Click Build Path, then the libraries tab. Click add library, then select Server Runtime. Select your server and click OK.

can you please tell me why you do this? What is the logic behind this, as I have set the classpath in enviroment variables for servlet-api.jar and jsp-api.jar why it not works? – kamil Apr 02 '13 at 17:56

check project build path whether Servlets api jar file is included or not. you can add it in two ways:

1) add servlets api .jar file to build path
or
2) add server runtime (i add Tomcat server runtime library) in build path

Hope this helps.

If your project is maven then add following dependancy :

<!-- https://mvnrepository.com/artifact/javax.servlet/servlet-api -->
<dependency>
    <groupId>javax.servlet</groupId>
    <artifactId>javax.servlet-api</artifactId>
    <version>3.0.1</version>
    <scope>provided</scope>
</dependency>

Reference

For gradle projects:

dependencies {
providedCompile group: 'javax.servlet', name: 'javax.servlet-api', version: '3.0.1'
}

or download javax.servlet.jar and add to your project.

Steps:

Right click on project.
Go To Properties.
Go to Java Build Path.
Select Add Library option from tabs.
Add Jar Files give path of your servlet-api.jar file.
Clean and build your project.
