In Struts2, how to get HttpServletRequest and HttpServletReponse

[Ying Lu]

public class ProcessTestAction extends ActionSupport
{
public String execute() throws Exception
{
return success;
}
}

In the above codes, how to get request, and response? Any clues?




Tried this, but does NOT work:
=================================
public class ProcessTestAction extends ActionSupport
{
private HttpServletRequest request;
public void setServletRequest(HttpServletRequest request)
{
this.request = request;
}

public String execute() throws Exception
{
int len = request.getContentLength(); /* request is NULL ! */
return success;
}
}

Thanks a lot!

Your class needs to implement the ServletRequestAware interface.

It is relatively rare to need to HttpServletRequest within in action, so you should ask yourself first, "Do I really need this?"

Ok, I figured one way to get request and response


HttpServletRequest request = ServletActionContext.getRequest();
HttpServletResponse response = ServletActionContext.getResponse();

Proper way to do so would be by implementing:

ServletRequestAware, ServletResponseAware

Hi Eric,
Including Servlet related object will make it difficult for testing outside servlet container.
But what should one do if a project requires servlet related object to be used.
What is your opinion?
