Subject Getting request as null
Date Wed, 07 Nov 2012 12:17:34 GMT
Hi,

I am getting request object as null. Checked google..no help..


*Class where I am getting null*

package com.home.practice.shop;

import javax.servlet.ServletContext;
import javax.servlet.http.HttpServletRequest;

import org.apache.struts2.ServletActionContext;
import org.springframework.web.context.WebApplicationContext;
import org.springframework.web.context.support.WebApplicationContextUtils;

import com.home.practice.shop.domain.logic.PetStoreFacade;
import com.opensymphony.xwork2.ActionSupport;

public  class BaseAction extends ActionSupport {

private PetStoreFacade petStore;
HttpServletRequest request = ServletActionContext.getRequest();
 public void setServlet() {

ServletContext context = ServletActionContext.getServletContext();
WebApplicationContext wac = WebApplicationContextUtils
.getRequiredWebApplicationContext(context);
this.petStore = (PetStoreFacade) wac.getBean("petStore");

}

protected PetStoreFacade getPetStore() {
return petStore;
}

}

But strangely in the following class the same code I have wriiten and I am
getting request object

public class ViewCategoryAction  extends BaseAction {

public String execute() throws Exception {
HttpServletRequest request = ServletActionContext.getRequest();
System.out.println("******************" + request);


Why is it so ? ServletActionContext.getRequest() is returning null in base
class but not in child class.
