Hi,

When I run my web application (struts2) , the index page is displayed correctly. When I click the button on the index page, the following error occurs:

HTTP Status 500 -

type Exception report

message

description The server encountered an internal error () that prevented it from fulfilling this request.

exception

java.lang.NullPointerException
org.apache.struts2.impl.StrutsActionProxy.getErrorMessage(StrutsActionProxy.java:69)
com.opensymphony.xwork2.DefaultActionProxy.prepare(DefaultActionProxy.java:185)
org.apache.struts2.impl.StrutsActionProxy.prepare(StrutsActionProxy.java:63)

org.apache.struts2.dispatcher.FilterDispatcher.doFilter(FilterDispatcher.java:434)
note The full stack trace of the root cause is available in the Apache Tomcat/6.0.35 logs.

I'm not able to understand the reason. I'm new to web app development, please help..

Can you show us the complete stack trace?
