Check that the version number of your servlet-api jar is at least 3 0  There is a version number inside the jar in the META-INF manifest mf file   Implementation-Version  3 0 1   If it s less than 3 0 download the 3 0 1 from Maven Central  http   search maven org  artifactdetails javax servlet javax servlet-api 3 0 1 jar  Former servlet specifications  2 5  2 4 etc   do not support annotations

I had the same issue  it turns that I had my project configured as many of you stated above  yet the problem persisted  so I went deeper and came across that I was using Apache Tomcat 6 as my Runtime Server  so the fix was simple  I just upgraded the project to use Apache Tomcat 7 and that s all  finally the IDE recognized javax servlet annotation WebServlet annotation

I tried to import the servlet-api jar to eclipse but still the same also tried to build and clean the project  I don t use tomcat on my eclipse only have it on my net-beans  How can I solve the problem   Do not put the servlet-api jar in your project  This is only asking for trouble  You need to check in the Project Facets section of your project s properties if the Dynamic Web Module facet is set to version 3 0  You also need to ensure that your  WEB-INF web xml  if any  is been declared conform Servlet 3 0 spec  I e  the  lt web-app gt  root declaration must match the following   lt web-app     xmlns  quot http   java sun com xml ns javaee quot       xmlns xsi  quot http   www w3 org 2001 XMLSchema-instance quot      xsi schemaLocation  quot http   java sun com xml ns javaee http   java sun com xml ns javaee web-app 3 0 xsd quot      version  quot 3 0 quot  gt   In order to be able to import javax servlet stuff  you need to integrate a fullworthy servletcontainer like Tomcat in Eclipse and then reference it in Targeted Runtimes of the project s properties  You can do the same for Google App Engine  Once again  do not copy container-specific libraries into webapp project as others suggest  It would make your webapp unexecutabele on production containers of a different make version  You ll get classpath-related errors exceptions in all colors  See also   How do I import the javax servlet API in my Eclipse project    Unrelated to the concrete question  GAE does not support Servlet 3 0  Its underlying Jetty 7 x container supports max Servlet 2 5 only
