I have designed a Login page using Spring MVC,JPA(Hibernate) and Jsp.
Please find the login.jsp :-
<%# page language="java" contentType="text/html; charset=ISO-8859-1"
pageEncoding="ISO-8859-1"%>
<%# taglib uri="http://www.springframework.org/tags/form" prefix="form"%>
<%# taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<body>
<h2>Login page</h2>
<form:form method="POST" modelAttribute="loginBean" action="showProfile">
<table>
<tr>
<td>UserName :<form:input path="userName"/></td>
</tr>
<tr>
<td>Organization Id :<form:input path="OrgId" /></td>
</tr>
<tr>
<td>Password : <form:input path="password" /></td>
</tr>
<tr>
<td colspan="2"><input type="submit" value="Submit" /></td>
</tr>
</table>
</form:form>
</body>
</html>
profilePage.jsp:-
<%# page language="java" contentType="text/html; charset=ISO-8859-1"
pageEncoding="ISO-8859-1"%>
<%# taglib uri="http://www.springframework.org/tags/form" prefix="form"%>

LoginController.java:-
#Controller
public class LoginController {
#RequestMapping(value = "/", method = RequestMethod.GET)
public String showLoginPage(Model model) {
model.addAttribute("loginBean", new LoginBean());
return "login";
}
#RequestMapping(value = "/showProfile", method = RequestMethod.POST)
public ModelAndView redirectToprofile(#ModelAttribute("loginBean") LoginBean loginBean) {
StaffServiceImpl staffServiceImpl = new StaffServiceImpl();
Staff staff = staffServiceImpl.authenticateStaff(loginBean);
if (null != staff) {
return new ModelAndView("redirect:/profilePage","staffData",staff);
}
return new ModelAndView("profileNotFound");
}
#RequestMapping(value = "/profilePage", method = RequestMethod.GET)
public String showProfilePage() {
return "profilePage";
}
After giving the valid details in the Login.jsp page it is redirecting to profilePage.jsp but the data in profilePage.jsp is not correct. Please help me to understand where i am doing the mistake.
The profilePage.jsp is displayed a below:-
UserName Password
${staff.userName} ${staff.password}
The Value of this variable is not getting displayed.
profilePage.jsp : Add isELIgnored="false" in page directive.
<%# page language="java" contentType="text/html; charset=ISO-8859-1"
pageEncoding="ISO-8859-1" isELIgnored="false"%>
Update your controller with the following :
#Controller
public class LoginController {
#RequestMapping(value = "/", method = RequestMethod.GET)
public String showLoginPage(Model model) {
model.addAttribute("loginBean", new LoginBean());
return "login";
}
#RequestMapping(value = "/showProfile", method = RequestMethod.POST)
public String redirectToprofile(#ModelAttribute("loginBean") LoginBean loginBean , Model model) {
StaffServiceImpl staffServiceImpl = new StaffServiceImpl();
Staff staff = staffServiceImpl.authenticateStaff(loginBean);
if (null != staff) {
model.addAttribute("staffData",staff);
return "profilePage";
}
return "profileNotFound";
}
the above answer is correct, and this is an explination:
The isELIgnored attribute gives you the ability to disable the evaluation of Expression Language (EL) expressions which has been introduced in JSP 2.0.
The default value of the attribute is true, meaning that expressions, ${...}, are evaluated as dictated by the JSP specification. If the attribute is set to false, then expressions are not evaluated but rather treated as static text.

I Have a class that find Google search results. And i have a JSP page that i want to show the results in. But i can't do it.
Heres my UrlOku class :
public static void GetUrl() {
final String keyword = "emre varol";
final String url = "https://www.google.com/search?q="+keyword;
try {
final Document document = Jsoup.connect(url).get();
List<String> myList = new ArrayList<String>();
for(Element row: document.select("div[class=g]")) {
final String title = row.select("div[class=TbwUpd NJjxre]").text();
myList.add(title);
}
}
And heres my JSP page :
<%# page language="java" contentType="text/html; charset=UTF-8"
pageEncoding="UTF-8"%>
<%# page import="urlpaket.Urloku" %>
<%# taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c"%>
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title>Insert title here</title>
</head>
<body>
<jsp:include page="menu.jsp"></jsp:include>
<%
if(session.getAttribute("username")==null){
response.sendRedirect("login.jsp");
}
%>
WELCOME ${username}
<%
Urloku oku = new Urloku();
oku.GetUrl();
%>
<c:forEach items="${myList}" var="item">
<tr>
<td><c:out value="${item.title}" /></td>
</tr>
</br>
</c:forEach>
And there is nothing in the welcome.jsp file.
Any help would be appreciated!
How is myList variable available in you JSP? This needs to be set in pageContext before accessing it using ${myList}.
You can change the signature to public static List GetUrl()
and do something like this
Urloku oku = new Urloku();
List<String> myList = oku.GetUrl();
pageContext.setAttribute("myList ",myList );
Now it should be available.
I am trying to map productId to URL in my jsp page, but the value is wrong.
The URL is returning TÃtulo 1 but the response is returning the right value:

My jsp code:
<%# page language="java" contentType="text/html; charset=iso-8859-1" pageEncoding="iso-8859-1"%>
<%# taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c"%>

My Java Controller Code:
#RequestMapping(method=RequestMethod.GET)
public ModelAndView list() {
ModelAndView modelAndView = new ModelAndView("products/list");
modelAndView.addObject("products", productDAO.list());
return modelAndView;
}
My Java DAO Code:
public List<Product> list() {
return manager.createQuery("select distinct(p) from Product p join fetch p.prices", Product.class).getResultList();
}
Unfortunately I cannot see your method 'show'.
I guess you have a misprint in the path:
#RequestMapping("/show{/id}")
//--------------------^^ WRONG
public String show(#PathVariable("id") long id) {
...
}
instead
#RequestMapping("/show/{id}")
//--------------------^^ RIGHT
I am getting values from DAO its stored in varaible editVal and page return to edit.jsp now how to get varaible editVal values in edit.jsp page..
Controller page:
#RequestMapping(value="edit", method=RequestMethod.GET)//String
public ModelAndView callgetSuccess(#ModelAttribute("id")String Id, BindingResult result, ModelMap model) {
ModelAndView shop=new ModelAndView();
shopModel shModel=new shopModel();
if(result.hasErrors()){
System.out.println("error");
return new ModelAndView("edit","shopModel",editVal);//"edit"
}else{
shModel = shopService1.editshop(Id);
model.addAttribute("shopModel",shModel);
shop.addObject("shopModel", shModel);
return new ModelAndView("edit","shopModel",shModel);
}
edit.jsp
<%# taglib uri="http://www.springframework.org/tags" prefix="spring"%>

<h2>Hello World!</h2>
<form>
<h1>Success</h1>
edit page
<c:out value="${id}" />
</form>
</body>
</html>
Edit.jsp Page Imge
edit jsp page image
As editVal is a string, you can access it <c:out value="${shopModel}" />
If its a list of string, then the following can be used
<c:forEach var="shop" items="${shopModel}">
<c:out value="${shop}" />
</c:forEach>
If its a list of objects, then var.<object attribute name> as follows
<c:forEach items="${shopModel}" var="shop">
<tr>
<td>${shop.name}</td>
<td>${shop.number}</td>
...
</tr>
</c:forEach>
I am new to spring framework. Currently, I am doing spring validations using annotations.
So look at my DAO Class:
public class Spitter {
private Long id;
#NotNull(message = "Username cannot be null")
#Size(min = 10, max = 14, message = "Username must be between 10 and 14 characters long")
private String username;
SETTERS AND GETTERS }
This is my controller:
#Controller
#RequestMapping("/spitters")
public class SpitterController {
#RequestMapping(value = "/edit", method=RequestMethod.GET)
public String createSpitterProfile(Model model) {
model.addAttribute("spitter", new Spitter());
return "spitters/edit";
}
#RequestMapping(value = "/edit/createAccount", method = RequestMethod.POST)
public String addSpitterFromForm(Model model, #Valid #ModelAttribute("spitter")Spitter spitter, BindingResult bindingResult) {
if (bindingResult.hasErrors()) {
return "spitters/edit";
} else {
// spitterService.addSpitter(spitter);
return "redirect:/home";
}
}
}
And JSP file:
<%--suppress XmlDuplicatedId --%>
<%# page language="java" contentType="text/html; charset=ISO-8859-1"
pageEncoding="ISO-8859-1"%>
<%# taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core"%>
<%# taglib prefix="s" uri="http://www.springframework.org/tags"%>
<%# taglib prefix="fmt" uri="http://java.sun.com/jsp/jstl/fmt"%>
<%# taglib prefix="sf" uri="http://www.springframework.org/tags/form"%>
<%# taglib prefix="form" uri="http://www.springframework.org/tags/form" %>
<!DOCTYPE html>
<html lang="en">
<head>
<title>Spitter</title>
</head>
<body>
<h2>Create free Spitter account</h2>
<sf:form action="/spitters/edit/createAccount"
method="post" commandName="spitter">
<table class="formtable">
<tr>
<td class="label">User Name</td>
<td><sf:input class="control" name="username" path="username"
type="text"></sf:input></br>
<sf:errors path="username"></sf:errors></td>
</tr>
<td class="label"></td>
<td><input type="submit" value="Submit"></td>
</tr>
</table>
</sf:form>
</body>
</html>
However, Spitter Controller can receive data from jsp form. But constraints(#NotNull and #Size) added in DAO Class don't work and I don't know why.
Please be more spceific about the non-working constraints. An example
would help
Maybe your bean data is valid and username is just empty string. I think you use Hibernate Validator, if so try to add #NotEmpty constraint to username field
I believe you need to register bean MethodValidationPostProcessor. See Spring Docs
Hi i am new in jsp and Spring. I have a table of employee information. I want to add a edit link in each row and an edit link will be click it will send the primary key of the row to the controller. When i click the edit link it display the error "The request sent by the client was syntactically incorrect ()."
This page display the table

How i can solve this problem.
Change your jsp to something like this
<c:url var="editUrl" value="/editEmployee.htm" />
<a href="${editUrl}?id=${employeeList.id}">
Edit
</a>
<c:url var="deleteUrl" value="/deleteEmployee.htm" />
<a href="${deleteUrl}?id=${employeeList.id}">
Delete
</a
#RequestMapping(value="/editEmployee.htm") - wrong
#RequestMapping(value="/editEmployee/{id}")
public String editEmployee(#PathVariable int id,ModelMap model){
try {
Employee employee = employeeService.getEmployeeById(id);
model.addAttribute("employee", employee);
return "editEmployee";
} catch (Exception ex) {
return "index";
}
}
and also a href="editEmployee.htm?id=${id}
this should be something like a href="editEmployee/${id}
