The exception says it all, Have you crated the Action class which assigned to name "HelloWorld" ..

something like this in your 'struts.xml ; ,

 <action name="HelloWorld" class="example.HelloWorld">
            <result>/HelloWorld.jsp</result>
        </action>   

and make sure that you placed the xml in classpath !

Thanks for your reply. I wrote the following code in my struts.xml.

  
<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE struts PUBLIC
"-//Apache Software Foundation//DTD Struts Configuration 2.0//EN"
"http://struts.apache.org/dtds/struts-2.0.dtd">
 
<struts>
 
<constant name="struts.enable.DynamicMethodInvocation" value="false" />
<constant name="struts.devMode" value="true" />
 
<package name="hello" namespace="hello" extends="struts-default">
 
<action name="HelloWorld" class="hello.HelloWorld">
<result>/pages/HelloWorld.jsp</result>
</action>
 
<!-- Add actions here -->
</package>
 

<!-- Add packages here -->
 
</struts>

Have you checked where is your 'struts.xml ' file is saved , Store it into source package !

[Maheswaran Devaraj]

Thank you Sagar Rohankar. I placed my struts.xml file inside of the webcontent directory. Now I moved it to the src directory ,now the program is running successfully. Than you.
