How to pass a parameter to an included page with JSF 1.2

阅读更多关于 How to pass a parameter to an included page with JSF 1.2

Is this possible to pass a parameter to an included page in JSF1.2 environment? I have a page a.jsp in which b.jsp is included twice (I tested all jsp:include, a4j:include, c:import) once at top of the page and once at the bottom. I want to figure out in b.jsp if it's now including in top or in bottom of a.jsp. BTW, I do not have facelets. There the <jsp:param> tag is for. E.g. <jsp:include page="/WEB-INF/include.jsp"> <jsp:param name="position" value="top" /> </jsp:include> ... <jsp:include page="/WEB-INF/include.jsp"> <jsp:param name="position" value="bottom" /> </jsp:include> With the above

I need to load some html pages created dynamically by some other application into my application jsp page using jsp include tag <jsp:include page="${Htmlpath}" /> OR <jsp:include page="D:\MySharedHTML\test.html" /> . My idea is to have a shared folder on server like "MySharedHTML" and let other application create html files there and my app will access by giving full path. But jsp include is saying "requested resource D:\MySharedHTML\test.html is not available". Any inputs how to do it. Thanks In Advance. It has to be available by an URL.

I have exactly the same basic question about accessing jsp:param values as this poster; following his example exactly does not work for me. The parameters passed in via jsp:include don't seem to show up in the included file. Is there something peculiar about my setup? Caller: <div> <jsp:include page="../../../common/callee.jsp"> <jsp:param name="justinVar" value="primary" /> </jsp:include> </div> callee.jsp: <i>method 1: [</i><b><%= request.getParameter("justinVar") %></b><i>]</i> <p/> <i>method 2: [</i><b>${param.justinVar}</b><i>]</i> <p/> <i>method 3: [</i><b>${justinVar}</b><i>]</i> <p/>

unable to add a cookie included in JSP via jsp:include

阅读更多关于 unable to add a cookie included in JSP via jsp:include

Cookies are not getting added to the browser when the code adding the cookie is part of a fragment of JSP (includes.jsp) included in the primary page (main.jsp) via JSP:INCLUDE. The code works fine when it is part of the primary page (main.jsp). However, I need to add the cookie via the fragment since that fragment is used in dozens of pages where I want the cookie to get added. Note: The jsp:include is part of the header section of main.jsp (the fragment also adds a number of javascript and css references) Here is the snippet: Cookie cookie = new Cookie ("test","test cookie"); cookie

问题 home.jsp <jsp:useBean id="username" class="java.lang.String" scope="application"/> <% username="Jitendra"; %> <jsp:include page="include.jsp"/> include.jsp <%=username%> This gives an error saying “username” is undefined in include.jsp, even though the scope of Bean is application… 回答1: As to your problem, anything which you declare locally using the old fashioned scriptlets is not linked with a jsp:useBean . Also, declaring a local scriptlet variable is not visible in the included pages, you
