1) Make sure that you have placed following necessary jar files in classpath.

antlr-2.7.2.jar
commons-beanutils-1.8.0.jar
commons-collections-3.1.jar
commons-fileupload-1.3.1.jar
commons-io-2.2.jar
commons-lang3-3.2.jar
commons-logging-1.1.3.jar
struts2-core-2.3.20.jar
xstream-1.4.2.jar
xwork-core-2.3.20.jar
ognl-3.0.6.jar
freemarker-2.3.19.jar

2) Make sure your web.xml is correct, below is one sample

<!DOCTYPE web-app PUBLIC
 "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN"
 "http://java.sun.com/dtd/web-app_2_3.dtd" >

<web-app>
  <display-name>Struts 2 Web Application</display-name>

  <filter>
    <filter-name>struts2</filter-name>
    <filter-class>org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter</filter-class>
  </filter>

  <filter-mapping>
    <filter-name>struts2</filter-name>
    <url-pattern>/*</url-pattern>
  </filter-mapping>

</web-app>

3)Make sure struts.xml is on classpath .you can place it on default package .Or you can place it on resources folder if you follow maven approach .Or you can place it on the folder where manifest.mf is placed(usually it is src/conf/manifest.mf in case of netbeans ide)

4) Finally, if you are planning to use other jar files, include it also on the classpath.
