RE: global variables-update

2002-10-04 Thread Galbreath, Mark 

There really is no substitute for reading the API and the Servlet
Specification (check out Chapter 3).  The spec explains more than you
probably would ever need to know about servlets and their contexts.  You can
download it from java.sun.com/products/servlet.

RE: global variables-update

2002-10-04 Thread Galbreath, Mark 

It's not a bean; it's a helper (Action) class that is passed the servlet
request and response objects, getting a "handle" on the servlet and can
access the context in which the servlet resides.  The context is the
global/application scope; the context object is like the central switching
office to every object that lives within the application.

Hi Divakar!
Thanks for the suggestion.

I am still confused with one thing
In the example provided by struts (struts-example), I found that they are 
calling getServletContext from the Action bean to get a global/application 
scope attribute,
but I felt it strange as there is no servlet passed to the Action Bean.

The code is as follows:
public final class SaveRegistrationAction extends Action {

public ActionForward perform(ActionMapping mapping,
  ActionForm form,
  HttpServletRequest request,
  HttpServletResponse response)
 throws IOException, ServletException {

 // Extract attributes and parameters we will need
 Locale locale = getLocale(request);
 .
 ..
 Hashtable database = (Hashtable)
   servlet.getServletContext().getAttribute(Constants.DATABASE_KEY);
 if (servlet.getDebug() >= 1)
 servlet.log("SaveRegistrationAction:  Processing " + action +
 " action");
 
 .
}
}

Any idea where this servlet is coming from???

Madhavi ,

  You can look at the users guide available at the struts site. You can make
use of request.setAttribute( ) for setting up global variables.
   Refer 2.2 JavaBeans and Scope of user doc 

http://jakarta.apache.org/struts/doc-1.0.2/userGuide/building_model.html
