Your web application uses a simple architecture in which servlets handle requests and then forward to aJSP using a request dispatcher. You need to pass information calculated by the servlet to the JSP；furthermore， that JSP uses a custom tag and must also process this information. This information mustNOT be accessible to any other servlet， JSP or session in the webapp. How can you accomplish this goal？（）A、Store the data in a public instance variable in the servlet.B、Add an attribute to the request object before using the request dispatcher.C、Add an attribute to the context object before using the request dispatcher.D、This CANNOT be done as the tag handler has no means to extract this data.
Your IT department is building a lightweight Front Controller servlet that invokes an application logic objectwith the interface： public interface ApplicationController {public String invoke（HttpServletRequest request）} The return value of this method indicates a symbolic name of the next view. From this name， the FrontController servlet looks up the JSP URL in a configuration table. This URL might be an absolute path or apath relative to the current request. Next， the Front Controller servlet must send the request to this JSP togenerate the view. Assume that the servlet variable request is assigned the current HttpServletRequestobject and the variable context is assigned the webapp’s ServletContext. Which code snippet of the FrontController servlet accomplishes this goal？（）A、Dispatcher view=context.getDispatcher（viewURL）；view.forward Request（request， response）；B、Dispatcher view=request.getDispatcher（viewURL）；view.forward Request（request， response）；C、RequestDispatcher view. =context.getRequestDispatcher（viewURL）；view.forward（request，response）；D、RequestDispatcher view=request.getRequestDispatcher（viewURL）；view.forward（request， response）；
