Error while extending StrutsPrepareAndExecuteFilter

[sarada bokka]

Hi all,

I have extended StrutsPrepareAndExecuteFilter

package com.tricky.dispatcher;
import javax.servlet.FilterConfig;
import javax.servlet.ServletException;

import org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter;
import org.hibernate.HibernateException;

import com.tricky.util.HibernateUtil;

class TrickyDispatcher  extends StrutsPrepareAndExecuteFilter {
	
	@Override
	public void init(FilterConfig filterConfig) throws ServletException {
	super.init(filterConfig);
	try {
	HibernateUtil.createSessionFactory();
	
	} catch (HibernateException e) {
	throw new ServletException(e);
	}

	}

}

In web.xml file i have changed

<filter>
<filter-name>struts2</filter-name>
<filter-class>com.tricky.dispatcher.TrickyDispatcher</filter-class>
</filter>


server has thrown the below error

SEVERE: Exception starting filter struts2
