Why there is an error in import javax.servlet.*?

Question

I am using JavaSE6 and Eclipse, there is an error in the line

import javax.servlet.*

It seems there is no jar for this import.

How to fix it? Install anything, use Eclipse EE or add some dependency in Maven?

Answer 1

The servlet API is not a part of the JDK, you need to add an additional dependency to your pom.xml.

If this is for a webapp you can add this dependency with provided scope and the servlet container will make these classes available to your webapp at deployment time.

<dependency>
  <groupId>javax.servlet</groupId>
  <artifactId>servlet-api</artifactId>
  <version>2.5</version>
  <scope>provided</scope>
</dependency>

Answer 2

javax.servlet.* is part of the Servlet API (which is part of the Java EE framework). Web Application Server/Web Containers wishing to use Servlets must implement the Servlet API.

Tomcat has servlet-api.jar which can be found under TOMCAT_HOME/lib (in Tomcat 6 and higher). Find one that's relevant to you based on the Web Application Server you're running.
