I'm trying to output some information from table users on my JSP page, but there is no output there.
Here is my controller method:
#Autowired
private UsersService usersService;
#RequestMapping(value="/user**")
public String getUserProfile( ) {
ModelAndView mav = new ModelAndView("userInfo");
List<Users> userInfo = usersService.userInfo("Oleg");
mav.addObject("userInfo", userInfo);
return "user";
}
Here is my DAO method
#SuppressWarnings("unchecked")
#Override
public List<Users> userInfo(String username) {
Transaction tx = sessionFactory.getCurrentSession().beginTransaction();
Session session = this.sessionFactory.getCurrentSession();
String query = "select users.username, users.name, users.surname, users.email, users.gender, users.age, users.weight, users.height, users.sport, users.place from users where users.username LIKE '%s'";
List<Users> userInfo = session.createSQLQuery(String.format(query,username)).list();
tx.commit();
return userInfo;
}
Here is my Service layer method
<%# taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core"%>
<html>
<head>
<title>User Profile Page</title>
</head>
<body>

I have a problem transferring data between two jsp
There are two controllers in which the first one accepts the input data, second generate lines with using this params
First controllers group receives two params
#RequestMapping(value = "/create", method = RequestMethod.POST)
public String ProjectSizePost(
#RequestParam("countSprints") Integer countSprints,
#RequestParam("countWorkers") Integer countWorkers) {
BigInteger a = BigInteger.valueOf(countSprints);
return "project/project_size";
}
#RequestMapping(value = "/create", method = RequestMethod.GET)
public String projectSizeGet() {
return "project/project_size";
}
And his jsp
<%#taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c" %>
<%# page language="java" contentType="text/html; charset=UTF-8"
pageEncoding="UTF-8" %>
<html>

<body>
<%--<c:forEach var="inputLine" begin="1" end="4">

Second controller and jsp must take params from first jsp
#RequestMapping(value = "/create", method = RequestMethod.POST)

MapperDateConverter mdc = new MapperDateConverter();
*//*Project project = new Project.ProjectBuilder()
.projectId(BigInteger.valueOf(id))
.name(name)
.startDate(mdc.convertStringToDate(startDate))
.endDate(mdc.convertStringToDate(endDate))
.build();
project.setProjectStatus(projectStatus);
project.setProjectManagerId(BigInteger.valueOf(projectManagerId));*//*
//projectDao.createProject(project);

Params countSprints and countWorkers
i cannot show any values and i dont get any error messages. . here is my code:
Number: <input type="text" name="number" />
<br>
<% Persone =(Employqq)request.getAttribute("cust"); %>
<table id="table" border="1">

for(Employee t : emp){ %>
<tr>
<td>
<%= t.getnumber() %>
</td>
<% } } %>
</tbody>

i appreciate all the help that i can get
You set the attribute in your servlet as Cust, and in your JSP you read it as cust
This is my coding for order.jsp, a form for customer to insert order and I use session.menus to display option menu in a HTML input element from database. I already connect to database using jdbcutility.java, where I put sql statement to connect my servlet with database and its working for login but not for this session.
<form class="form-horizontal" method="post" action="InsertOrderServlet">
<center>
<table border="10" cellpadding="20" cellspacing="20">
<thead>
<tr>
<th colspan="2"><h2 style="line-height: 3;" >Order Food</h2></th>
</tr>
</thead>
<tbody>
<tr>
<td><br><br>Food</br></br></td>

<br><br>
<div class="col-lg-9">
<select class="form-control" name="menuName">
<c:forEach items="${sessionScope.menus}" var="currentmenu" varStatus="loop">
<option><c:out value="${currentmenu.foodName}" /></option>
</c:forEach>
</select>
</div>
</td>
</tr>
<tr>
<td>Quantity</td>
<td><input type="text" name="quantity" required/></td>
</tr>
<tr style="line-height: 10;" >
<td> <button class="btn btn-primary" type="reset" >Cancel</button></td>
<td > <button type="submit" class="btn bt primary">Submit</button></td>
</td>
</tr>
</tbody>
</table>
</center>
</form>
getMenuServlet.java
//select all from menu
try {
ResultSet rs = jdbcUtility.getPSSelectMenu().executeQuery();
while (rs.next()) {
menu = new Menu();
menu.setId(rs.getInt("menuid"));
menu.setfoodName(rs.getString("foodName"));
menu.setImage(rs.getString("image"));
menu.setPrice(rs.getDouble("price"));
//put into arraylist
menus.add(menu);
}
}
catch (SQLException ex)
{
}
//put into sessions
session.setAttribute("menus", menus);
jdbcutility.java
String sqlValidateLogin = "Select username,password from customer where username=? and password=?";
psInsertLogin = con.prepareStatement(sqlValidateLogin);
String sqlInsertOrder = "INSERT INTO orderfood(menuName, quantity) " + "VALUES(?, ?)";
psInsertOrder = con.prepareStatement(sqlInsertOrder);
String sqlSelectAllMenu ="SELECT * FROM menu";
psSelectAllMenu = con.prepareStatement(sqlSelectAllMenu);
String sqlSelectAllOrder ="SELECT * FROM orderfood";
psSelectAllOrder = con.prepareStatement(sqlSelectAllOrder);
This keep occurring, how do I fix this?

Make sure the JSP is allow access session.
<%# page session="true" %>
To use core JSTL, make sure the following code is included.
<%#taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c"%>
I am new to Spring.
I am trying to show error messages on jsp for the wrong user and password by using BindingResult. But the error messages are not showing.
Please suggest me what I is wrong in the below code.
JSP
<script type="text/javascript">
function loginUser() {
$('#loginForm').submit();
}
</script>
</head>
<body>
<form:form action="login.test" id="loginForm" commandName="loginForm" method="POST">
<div class="brand_area"></div>
<div class="content_area">
<table style="top: 360px; position: relative; margin-left: 333px;">
<tr id="uNameID">
<td class="label">User Name:</td>
<td><form:input id="userNameID" path="userName" class="textInput" /></td>
<td><form:errors path="userName" class="error"/></td>
</tr>
<tr id="pID">
<td class="label">Password:</td>
<td><form:password id="passwordID" path="password" class="textInput" /></td>
<td><form:errors path="password" class="error"/></td>
</tr>
<tr>
<td></td>
<td><span id="saveButton" class="loginButton"
onclick="loginUser()"> <span>Login</span>
</span></td>
</tr>
</table>
</div>
</form:form>
Controller
#RequestMapping(value = "login.test", method = RequestMethod.POST)
public String processForm( LoginForm loginForm, BindingResult result, ModelMap model, HttpSession session) throws SQLException {
String resultedPage;
model.addAttribute("l_nodes", reportService.getAllLiveNodes());
model.addAttribute("s_nodes", reportService.getAllStaticReportNodes());
User user = userService.getUserByName( loginForm.getUserName() );
if( user != null ){
session.setAttribute("userID", user.getUserID());
if( loginForm.getPassword().equals( user.getPassword() ) ){
resultedPage = "home/userHome";
}else{
result.rejectValue( "password", "login.passwordNotValid");
resultedPage = "redirect:login.test";
}
}else{
result.rejectValue( "userName", "login.userNotValid");
resultedPage = "redirect:login.test";
}
return resultedPage;
}
Thanks
In case anyone else research the same...
Add the hasBindErrors tag to your JSP:
<spring:hasBindErrors name="loginForm">
<c:forEach var="error" items="${errors.allErrors}">
<b><spring:message message="${error}" /></b>
<br/>
</c:forEach>
</spring:hasBindErrors>
Well, i generally send back the values using the Model object.
May be this answer might help you.
I have 2 pages, the first where the user insert the data, and the second where the user confirm the data (or can go back to the edit page).
The problem is that when validation fails, all the values in fields are erased. Somebody suggested to use prepare(), but It's a lot of work to copy all the fields, does it exist a faster way to repopulate all the fields?
the first page (formDatiUtente.jsp):

The superclass of InserimentoDatiAction:
public class RegisterAction extends ActionSupport implements SessionAware {
private static final long serialVersionUID = 1L;
private Anagrafica anagraficaVDR = new Anagrafica();
private String comuneSelezionatoVDR;
private String ilTuodominio_EmailVDR;

[...other less important stuff...]
}
part of struts.xml, formDatiUtente is the first jsp, visualizzaDatiRichiesta is the second (confirmation jsp):
<action name="inserimentoDati"
class="it.alm.action.InserimentoDatiAction">
<result name="success">/jsp/creazioneUtenza/formDatiUtente.jsp</result>
</action>
<action name="inviaRichiesta"
class="it.alm.action.InviaRichiestaAction">
<result name="success">/jsp/creazioneUtenza/visualizzaDatiRichiesta.jsp</result>
<result name="input">/jsp/creazioneUtenza/formDatiUtente.jsp</result>
<result name="backToMenuAdmin">/jsp/pannelloDiGestione/menu.jsp</result>
</action>
Action1 extends the one containing the AnagraficaVDR used to set the value;
Action2 extends simply ActionSupport, it doesn't know anything about an object called AnagraficaVDR.
When you post the form to Action2, and it fails validation, INPUT result returns the first JSP, without the first Action backing its data.
You have to rethink the mechanism a bit:
if you want to repopulate the first JSP with the ORIGINAL values from AnagraficaVDR, you have to provide AnagraficaVDR to Action2 too (maybe by declaring two actions in struts.xml pointing to two methods of the same action containing AnagraficaVDR...)
But this is generally avoided, because if I've changed 10 fields from their original values, and one of them is failing the validation, I want it to return my 10 ALTERED values, to be able to change only the failing one. With the solution provided above, it will reset all to AnagraficaVDR values, not the just entered values.
Then you should find another way, simpler and effective, like
populating your Action1 properties from AnagraficaVDR in the first Action execute (or
prepare) method,
remove all value="%{AnagraficaVDR.something" from your tags in JSP1.*
*NOTE: this is based on your previous question code, where the tag had name="properties" and value="%{AnagraficaVDR.properties}"
This way the first action will populate the values from AnagraficaVDR only the first time, then keeping the entered values in case of SUCCESS or INPUT.
