Here is one: Also I want to add some information about Java EE7: In Java EE 7, no changes were made to JSP and JSTL because these specifications have not been updated. Expression Language has been removed from JSP and now has its own JSR (341). Servlets and JSF have both been updated. WebSocket 1.0 … Read more
So, you want the base URL? You can get it in a servlet as follows: String url = request.getRequestURL().toString(); String baseURL = url.substring(0, url.length() – request.getRequestURI().length()) + request.getContextPath() + “/”; // … Or in a JSP, as <base>, with little help of JSTL: <%@taglib prefix=”c” uri=”http://java.sun.com/jsp/jstl/core” %> <%@taglib prefix=”fn” uri=”http://java.sun.com/jsp/jstl/functions” %> <c:set var=”req” value=”${pageContext.request}” /> … Read more
RedirectAttributes only work with RedirectView, please follow the same @RequestMapping(value=”/Login”,method = RequestMethod.POST) public RedirectView loginValidate(HttpServletRequest req, RedirectAttributes redir){ … redirectView= new RedirectView(“/foo”,true); redir.addFlashAttribute(“USERNAME”,uname); return redirectView; } Those flash attributes are passed via the session (and are destroyed immediately after being used – see Spring Reference Manual for details). This has two interests : they are … Read more
I was having this issue, too. Ensure jQuery is imported before highchart.js. That fixed the issue for me. <script src=”https://ajax.googleapis.com/ajax/libs/jquery/1.11.3/jquery.min.js”></script> <script src=”http://code.highcharts.com/highcharts.js”></script>
javax.el.PropertyNotFoundException: Property ‘foo’ not found on type com.example.Bean This literally means that the mentioned class com.example.Bean doesn’t have a public (non-static!) getter method for the mentioned property foo. Note that the field itself is irrelevant here! The public getter method name must start with get, followed by the property name which is capitalized at only … Read more
There are several ways to achieve this. Probably the easiest would be to use JavaScript to change the form’s action. <input type=”submit” value=”SecondServlet” onclick=”form.action=’SecondServlet’;”> But this of course won’t work when the enduser has JS disabled (mobile browsers, screenreaders, etc). Another way is to put the second button in a different form, which may or … Read more
The short answer is YES. It’s not a good solution but it will absolutely work. People usually answer these questions in theory, like “no, because it’s not valid by the standards”. That’s right, it’s not. Future browsers might not support it, some source parsers may get confused, HR/IT experts checking out your portfolio may think … Read more
JSF basically enables you to develop a web application with only model objects (JavaBeans) and views (JSP/XHTML pages). With “plain vanilla” JSP/Servlet you’ll have to bring in a lot of code to control, preprocess, postprocess, gather data, validate, convert, listen, etc the HTTP request and response. And then I’m not talking about refactoring it to … Read more
Try <%@ taglib prefix=”fmt” uri=”http://java.sun.com/jsp/jstl/fmt” %>
You can do similar things using JSP tag files. Create your own page.tag that contains the page structure. Then use a <jsp:body/> tag to insert the contents.
