Question

I got this big newbie question.
When i try the following; the ‘servlet’ turns red and indicates ‘Cannot resolve symbol ‘servlet’.

import javax.servlet.http.*;
import javax.servlet.ServletException;

I got apache tomcat running. I am a very big java newbie. Can anyone help me where to find a servlet library or something ? I googled but got no clear explanation of how to make this work.

This is the content of my web.xml file;

<?xml version="1.0" encoding="ISO-8859-1"?>
<web-app xmlns="http://java.sun.com/xml/ns/j2ee"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"
         version="2.5">

    <display-name>
        HelloWorld
    </display-name>
    <description>
        This is my first webapp
    </description>

    <servlet>
        <servlet-name>Hello world!</servlet-name>
        <description>This is a hello world servlet</description>
        <servlet-class>servlet</servlet-class>
    </servlet>

    <servlet-mapping>
        <servlet-name>HelloWorldServlet</servlet-name>
        <url-pattern>HelloWorldServlet</url-pattern>
    </servlet-mapping>

</web-app>

EDIT: I use the IntelliJ IDEA IDE.
And I am using Maven.

The servlet jar needs to be in your build path.

If you are using maven you could do this :

<dependency>
 <groupId>org.apache.tomcat</groupId>
 <artifactId>tomcat-servlet-api</artifactId>
 <version>7.0.21</version>
 <scope>provided</scope>
</dependency>

Or use one of the providers listed here, Such as the below which is not dependent on a specific container :

<dependency>
   <groupId>javax.servlet</groupId>
   <artifactId>javax.servlet-api</artifactId>
   <version>3.0.1</version>
   <scope>provided</scope>
</dependency>
