I'm having a problem with displaying a string in jsp view. A a web framework I'm using Spring MVC.
The view (return.jsp) is like that:
<%# page language="java" contentType="text/html; charset=UTF-8"
pageEncoding="UTF-8"%>
<%# taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c" %>
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title>FredomWings</title>
</head>
<body>
<b>Result -></b>
<p>${currentValue}</p>
</body>
</html>
The controller looks like that:
#RequestMapping(value="balance")
public String getBalance(Model model) {
model.addAttribute("currentValue","alalal");
return "return";
}
What is the reason for which in the jsp page only Result -> without any value is displayed?

my data, which I try to pass from my controller to the view is apparently ignored. The console doesn't output any errors. Can somebody point me to the apparently obvious mistake I did?
Controller
#RequestMapping("/notes")
public String index(ModelMap model) {
String test = "Hello Felix";
model.addAttribute("hello", test);
return "notes";
}
View
<%# taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c" %>
<%# page contentType="text/html; charset=UTF-8" %>
<!DOCTYPE html>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1">
<title>Notes</title>

<body>
<h1>${hello}</h1>
</body>

You need to return the model, something like the following should work:
Map model = ...
model.put(name, value);
return new ModelAndView(view, model);
I am doing on a MVC project using netbean IDE and I have a problem with displaying my objects on table
This is my jsp page
<%#page import="java.util.List"%>
<%#page import="java.util.ArrayList"%>
<%#page import="model.Clothes"%>
<%#page import="org.hibernate.Session"%>
<%#page import="cfg.HibernateUtil"%>
<%#page contentType="text/html" pageEncoding="UTF-8"%>
<%#taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>
<%#taglib prefix="display" uri="http://displaytag.sf.net" %>
<!DOCTYPE html>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title>Clothes</title>
</head>
<body>
<div style="margin-left: 10%; ">
<%
Session session1 = HibernateUtil.getSessionFactory().getCurrentSession();
List<Clothes> clothes = new ArrayList<Clothes>();
session1.beginTransaction();
clothes = session1.createQuery("from Clothes").list();
session1.getTransaction();
System.out.println(clothes.size() + "aaaaaaaaa");
session1.close();
request.setAttribute("results", clothes);
%>
<display:table name="results" pagesize="10"/>
</div>
<jsp:include page="/index.htm" flush="true"/>
</body>
And the browser display an exception at line contains 'display' tag like this:"org.apache.jasper.JasperException: An exception occurred processing JSP page /WEB-INF/jsp/clothes.jsp" Where did I do wrong, please help me, I am newbie in java web.
p/s: I add libs in my project, they are: displaytag-1.2, displaytag-export-poi-1.2, displaytag-portlet-1.2 and commons-lang-2.6.
I followed #JB Nizet instruction and it worked, just use the libs exactly the same that listed in this link: http://www.displaytag.org/1.2/displaytag/dependencies.html
However, in some PC, when using org.slf4j, your project can not work properly, just remove them from the project, it is OK!
My get ParameterValues method is not working, i am trying to retrieve the values from JSP page to MVC controller below is the code snipet for MVC page
#RequestMapping(value="/searchQuery", method=RequestMethod.POST)
public ModelAndView submitForm(HttpServletRequest request, ModelAndView model) {
System.out.println("Called submitfform method");
String[] listBox1 = request.getParameterValues("selectedright");
String[] listBox2 = request.getParameterValues("selectedright2");
String to_date=request.getParameter("date1");
String from_date=request.getParameter("date2");
System.out.println(listBox1);
System.out.println(listBox2);
List<ItemMaster> lists=itemDao.fetchRecords(listBox1,listBox2,to_date,from_date);
model.addObject("queryResult",lists);
model.setViewName("results");
System.out.println(lists.size());

When a file is selected it must set the fileName with path to a textField with path="inputFileName". I tried to below code which is not working as setFileName is not called either onClick nor onSelect.
Any pointers how this can be done will be great help to me.

System.out.println("In SetFile Name for InputFile");
}

I am trying to create a form. Where the user need to select a file path.
This can be done in html as
<input type="file" name="inputFileName"/>
If we use html then I don't know how to map that value to "fileObject" class.
So how should I do this with the following code throwing a warning "Undefined attribute name type "
<%# page language="java" contentType="text/html; charset=ISO-8859-1"
pageEncoding="ISO-8859-1"%>
<%#taglib uri="http://www.springframework.org/tags/form" prefix="f" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<body>
<f:form method="PUT" commandName="fileObject" >
<f:input type="file" path="inputFileName"/>
</f:form>
</body>
</html>
Exception:
org.apache.jasper.JasperException: /WEB-INF/jsp/Main.jsp(9,0) Attribute type invalid for tag input according to TLD
f:input does not have attribute type as you can find it in docs
