I am running the Struts2 application in eclipse but it is displaying the error while running in the Apache Tomcat server the error I am getting is SEVERE: Dispatcher initialization failed Unable to load configuration. - bean - jar:file:/C:/projectdetails/.metadata/.plugins/org.eclipse.wst.server.core/tmp0/wtpwebapps/FieldError/WEB-INF/lib/struts2-gxp-plugin-2.3.16.3.jar!/struts-plugin.xml:8:162 at com.opensymphony.xwork2.config.ConfigurationManager.getConfiguration(ConfigurationManager.java:70) at org.apache.struts2.dispatcher.Dispatcher.init_PreloadConfiguration(Dispatcher.java:445) at org

I'm using Struts 2.3.14.2 jars, but when I created the simple application, I'm getting the following error/exception. I almost did everything perfectly. I added almost all jars in the class path. But still getting this exception. Am I missing something ?
