How to Call DWR in servlet

[Ian Cabigon]

I'd like to ask if there is way for a servlet to get DWR object instances and possibly call its method? Or the other way around. DWR POJOs getting servlet instances.

As a follow up, how can i get servlet instances now that ServletContext.getServlet("servlet") is deprecated? is there a work around to get servlet instances. I really need to know how to implement interservlet communication, specially servlets communicating with DWR POJOs..

If you have some ideas, please share.

Thanks.

I'm completely lost. DWR is glue between JavaScript on the client and Java on the server.

What, specifically, are you trying to do?

Thank you for considering my question.

For example I have these classes

    
// Servlet Class
public class A extends HttpServlet{
    public void doGet(...)throws ...{

         performSomeServerSideProcessing();

         // 1.get Instance of DWRObj
         // 2. Call DWRObj.broadCastClient();         
    }
}

// DWR POJO Class
public class DWRObj{

    public String broadCastClient( String msg ){
        WebContext wctx = WebContextFactory.get();
        String currentPage = wctx.getCurrentPage();

        ScriptBuffer script = new ScriptBuffer();
        script.appendScript("receiveMessages(")
              .appendData(msg );
              .appendScript(");");

        // Loop over all the users on the current page
        Collection pages = wctx.getScriptSessionsByPage(currentPage);
        for (Iterator it = pages.iterator(); it.hasNext();)
        {
            ScriptSession otherSession = (ScriptSession) it.next();
            otherSession.addScript(script);
        }
    }
}

How do I do 1 and 2? Or is there a better way of doing this logic?
