Question

I have a login page. When the user enters valid Username and Password another page should be displayed. I check the username and password in processAction method. How can I forward to another jsp from processAction?

Answer 1

you need to use like this..

String myjsp;
public void init() {
        editJSP = getInitParameter("edit-jsp");
        helpJSP = getInitParameter("help-jsp");
        viewJSP = getInitParameter("view-jsp");
        //write your jsp page name 
        myjsp = getInitParameter("myjsp-jsp");

    }

//method to call jsp

protected void include(
            String path, RenderRequest renderRequest,
            RenderResponse renderResponse)
        throws IOException, PortletException {

        PortletRequestDispatcher portletRequestDispatcher =
            getPortletContext().getRequestDispatcher(path);

        if (portletRequestDispatcher == null) {
            _log.error(path + " is not a valid include");
        }
        else {
            portletRequestDispatcher.include(renderRequest, renderResponse);
        }
    }

//write this method call into action method

include(myjsp, request, response);

you can call using this method also….

 response.setRenderParameter("jspPage", "/admin/search.jsp");

this is easy and simplest method……..
