Here I am login using login method in AccountController class and adding a model attribute user and making changes in this object in the profile jsp page and after submitting the form its showing changes in the jsp page but not updating the changes in the database. Sometimes this exception also come -

What is the problem ?

You should first load the user then update user properties.
Your code will like this:
#Transactional
public boolean updateUser(User user){
boolean result = false;
Session session = sessionFactory.getCurrentSession();
try{
User useToUpdate = session.get(user.getId());
useToUpdate.setUsername(user.getUsername());
...
result = true;
} catch (Exception e){
result = false;
e.printStackTrace();
}
return result;
}
Hibernate will persist the changes when commiting the transaction, so you don't need to call session.update(user);

I checked my code and i find that my user object was taking id as 0 thats why exception came on updating. I set id on jsp page in the form and that issued my problem.

Internationalize in spring mvc/java. Translating only first line of messages.property

I got next problem with my application. I want to internationalize my pages. On first page I have problem, because app translate only first variable. Firstly i added messages_en.properties in src/main/resources.
addGame.form.gameId.label = Game ID
addGame.form.gameName.label = Game name
addGame.form.gamePlatform.label = Game platform
addGame.form.gamePrice.label = Game price
addGame.form.gameDescription.label = Game description
addGame.form.gameCategory.label = Game category
addGame.form.gamesInStock.label = Games in stock
addGame.form.condition.label = Game condition
addGame.form.gameImage.label = Game image
Next step was add choice of language in addGame.jsp. It's work good.
<div class="pull-right" style="padding-right:50px">
angielski
</div>
Next step in DispatcherServlet-context.xml added one bean.
<bean id="localeResolver"
class="org.springframework.web.servlet.i18n.SessionLocaleResolver">
<property name="defaultLocale" value="pl"/>
</bean>
And in same file
<mvc:interceptors>
<bean class= "org.springframework.web.servlet.i18n.LocaleChangeInterceptor">
<property name="paramName" value="language"/>
</bean>
</mvc:interceptors>
And last what i do was added language to GameController like this.
#InitBinder
public void initialiseBinder(WebDataBinder binder) {
binder.setDisallowedFields("unitsInOrder", "discontinued");
binder.setAllowedFields("gameId", "gameName", "gamePrice", "gameDescription","gamePlatform", "gameCategory", "gamesInStock", "gameImage", "language");
}
Screen from page
On screenshot you can see my page after click English language. its changing only first variable. Could you tell me why?
Mine code. You can see messages_en.properties up. This is DispatcherServlet-context.xml

I haven't idea what i doing wrong. Button of changing language working well, but it's translate only first variable no more. On screen you can see en version (not default) and it changed only first variable and next variable name its from default lang. I haven't problems in console when running application just one warning like this.
WARNING: [SetContextPropertiesRule]{Context} Setting property 'source' to 'org.eclipse.jst.jee.server:gamestoreCOPIED' did not find a matching property.
#EDIT:
Hi, after few days coding and repairing errors im back there. I got new informations.
PROBLEM : Application working good.
Locale change button working good. After click on this button application generate link (if english button click: http://localhost:8080/gamestore/games/add?language=en or if polish: add?language=pl)
and language are changing.
When i want change it on english language it translate me only first word of messages_en.properties. When i make english language default - its same situation - only first word its changing.
In console 0 errors only one warning but its nothing in this topic.
Problem is when i try change language on english or use on default english its change only first line of messages_en.properties.
If i change ResourceBundleMessageSource for ReloadableResourceBundleMessageSource(with changing classpath and make it good)
nothing changed.
<bean id="messageSource"
class="org.springframework.context.support.ReloadableResourceBundleMessageSource">
<property name="basename" value="classpath:messages" />
<property name="defaultEncoding" value="UTF-8" />

Spring Mvc App get - HTTP Status [404] – [Not Found]

I work with a Spring Mvc app and get HTTP Status [404] – [Not Found]. The landing page is namely index.jsp,
and called from the controller method,
#Controller
public class BitcoinWalletController {
#RequestMapping("/")
public String showBitcoinWallet() {
return "index";
}
}
In the index.jsp page, send money button is initially disabled,
<div class="buttons_box">
<button type="button" class="btn btn-default btn-lg active" <%= canSendMoney ? "" : "disabled='true'"%>
data-toggle="modal" data-target="#myModal">Send money
</button>
</div>
and only be active if the synchronization is completed and boolean canSendMoney returns true.
If the button is active, the code handles the POST operation is provided,
<%--modal contents here--%>
<div class="modal-content">
<div class="model-header">
<button type="button" class="close" data-dismiss="modal">&times!</button>
<h4 class="modal-title">Send Money</h4>
</div>
<form id="send-form" class="form-horizontal" action="sendMoney.jsp" method="POST">
<div class="modal-body">
<div class="form-group">
<label for="amount" class="col-sm-2 control-label">Send</label>
<div class="col-xs-4">
<input id="amount" name="amount" class="form-control" value="0">
</div>
<div class="btc-col">
<span>BTC</span>
</div>
</div>
<div class="form-group">
<label for="address" class="col-sm-2 control-label">to</label>
<div class="col-sm-10">
<input id="address" name="address" class="form-control">
</div>
</div>
</div>
<div class="modal-footer">
<button type="button" class="btn btn-default" data-dismiss="modal">Cancel</button>
<button type="submit" class="btn btn-default">Send</button>
</div>
</form>
</div>
The sendMoney.jsp code is provided below,
<body>
<%
String amount = request.getParameter("amount").trim();
String address = request.getParameter("address").trim();
WalletSendMoneyController.getSendMoneyController().send(address, amount);
// New location to be redirected
String site = new String("/");
response.setStatus(response.SC_MOVED_TEMPORARILY);
response.setHeader("Location", site);
%>
</body>
When I put all the required and correct infos and press the button, It should return to the original page- index.jsp. Instead, I get the error, HTTP Status [404] – [Not Found],
I currently don't have any handle for the address http://localhost:8080/sendMoney.jsp. Because, if the POST submission is correct, I would like to redirect to the "/".
I have the jsps in the WEB-INF folder in the project directory,
The jsps location provided in the dispatcher-servlet.xml file,
<bean id="jspViewResolver"
class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<property name="prefix" value="/WEB-INF/jsps/"></property>
<property name="suffix" value=".jsp"></property>
</bean>
The we.xml knows where the dispatcher-servlet.xml is located,
<servlet>
<description></description>
<display-name>dispatcher</display-name>
<servlet-name>dispatcher</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>dispatcher</servlet-name>
<url-pattern>/</url-pattern>
</servlet-mapping>
How to solve the issue? Thanks.

Your code showing: You are actually trying to submit form to sendMoney.jsp which is not exist(might be, cause i can't see your whole project). Though you need to submit the form to a controller with a ModelAttribute which you need to create.
The following things you have to do for POST to controller from form.
Make a class for form fields
public class Data {
private String address;
private String amount;
public Data() {
}
public String getAddress() {
return address;
}
public void setAddress(String address) {
this.address = address;
}
public String getAmount() {
return amount;
}
public void setAmount(String amount) {
this.amount = amount;
}
}
Bind a new Data object in GET controller where you load the form in HTML
#RequestMapping("/")
public String showBitcoinWallet() {
model.addAttribute("data", new Data());
return "index";
}
The following form will be in your index.jsp page, Where /send is the controller's mapping where to POST the form
<form:form id="send-form" modelAttribute="data" class="form-horizontal" action="/send" method="POST">
<div class="modal-body">
<spring:bind path="amount">
<div class="form-group">
<label for="amount" class="col-sm-2 control-label">Send</label>
<div class="col-xs-4">
<form:input path="amount" id="amount" name="amount" class="form-control" value="0"></form:input>
</div>
<div class="btc-col">
<span>BTC</span>
</div>
</div>
</spring:bind>
<spring:bind path="address">
<div class="form-group">
<label for="address" class="col-sm-2 control-label">to</label>
<div class="col-sm-10">
<form:input path="address" id="address" name="address" class="form-control"></form:input>
</div>
</div>
</spring:bind>
</div>
<div class="modal-footer">
<button type="button" class="btn btn-default" data-dismiss="modal">Cancel</button>
<button type="submit" class="btn btn-default">Send</button>
</div>
</form:form>
Following controller for /send POST
#RequestMapping(value = "/send", method = RequestMethod.POST)
public String sendMoney(Data data) {
//here will be your code for send money and whatever you have to do..
...send(data.getAddress(), data.getAmount());
return "redirect:/"; //here will the location where you want to redirect
}

<bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<property name="viewClass" value="org.springframework.web.servlet.view.JstlView"/>
<property name="prefix" value="/WEB-INF/views/" />
<property name="suffix" value=".jsp" />
</bean>
Have you defined this in your spring-config.xml file ??

Why this error is coming while uploading the image?
I am getting this error when I add
<bean id="multipartResolver" class="org.springframework.web.multipart.commons.CommonsMultipartResolver">
<property name="maxUploadSize" value="1048576" />
</bean>
to the servlet.xml file. I am using Spring 4.

You need to have separate parameter in editProfileHandlerController method like #RequestParam("file") MultipartFile file.
Issue is Spring internally adds parameter resolver based on parameter type.
In your case your wrapping MultipartFile field in your custom type Users that's why it is not working.
Modify your method like below will work:
#RequestMapping(value = "/editprofilehandler", method=RequestMethod.POST)
public ModelAndView editProfileHandlerController(#ModelAttribute("userForm") Users users
,#RequestParam("uploadImage") MultipartFile file, ModelMap model, HttpSession session)

change your multipart class name.like
org.springframework.web.multipart.commons.CommonsMultipartResolver.CommonsMultipartResolver

Spring, Spring-security : Spring-security returning 302, even if login failed

I am working on a Spring-MVC application in which I am using Spring-security for authentication and authorization. I am connecting to the webapp via Android using RestTemplate.
Currently, the problem I am having is that even if Login fails, i am receiving 302 instead of 200. Because of that, on the client-side I don't know that login has failed. After which when the user tries to access secured-resource, access is denied and the app dies.
Can anyone tell me how to return correct response-code when there is a Login failure and how to detect it via Response code. Thanks a lot.

}
}, new ResponseExtractor<String>() {

// Here I can get the code to determine if login was successful
List<String> cookies = response.getHeaders().get("Cookie");
if (cookies == null) {
cookies = response.getHeaders().get("Set-Cookie");
}
String cookie = cookies.get(cookies.size() - 1);
int start = cookie.indexOf('=');
int end = cookie.indexOf(';');
return cookie.substring(start + 1, end);
}
});
return null;
}
#Override

super.onPostExecute(aVoid);
}
}

security:form-login is designed for web apps rather than REST clients. Although you can use it, you'll run into the kind of trouble you've described here.
I recommend using security:http-basic instead (secured over HTTPS) and sending the login details each time.
Edit: If you insist on using form login, you'll need to tell the RestTemplate not to follow redirects, which you can do with the following (using Apache HttpComponents instead of the standard JRE HttpUrlConnection):
final HttpComponentsClientHttpRequestFactory factory = new HttpComponentsClientHttpRequestFactory();
final HttpClient httpClient = HttpClientBuilder.create().setRedirectStrategy(
new DefaultRedirectStrategy() {
#Override
public boolean isRedirected(HttpRequest request, HttpResponse response, HttpContext context) throws ProtocolException {
return false;
}
}
).build();
factory.setHttpClient(httpClient);
restTemplate.setRequestFactory(factory);

Spring model object becomes null on jsp

I have a spring project and my problem is that my model objects becomes null on jsp when I debug it in the controller it shows data but on jsp nothing is displayed and there are no errors in the log.
I have added spring tiles config recently and tiles are working fine but these objects stopped getting displayed earlier it was working fine.
I have searched a lot on this and checked same links like Spring Model Object is not rendering on stackoverflow but nothing worked.
Here is my controller:
#RequestMapping(value = "/viewClient", method = RequestMethod.GET)
public String viewClient(ModelAndView model) {
ArrayList<SystemUser> systemUsers = clientController.getAllUsers();
model = new ModelAndView("systemUsers");
model.addObject("systemUsers", systemUsers);
return "viewClient";
}

In the jsp the systemUsers are not getting iterated nor displayed not its size is getting displayed..

Make it correct and change return type to ModelAndView
#RequestMapping(value = "/viewClient", method = RequestMethod.GET)
public ModelAndView viewClient() {
ArrayList<SystemUser> systemUsers = clientController.getAllUsers();
ModelAndView model = new ModelAndView("viewClient");
model.addObject("systemUsers", systemUsers);
return model ;
}
OR use
#RequestMapping(value = "/viewClient", method = RequestMethod.GET)
public String viewClient(ModelMap model) {
ArrayList<SystemUser> systemUsers = clientController.getAllUsers();
model.addAttribute("systemUsers", systemUsers);
return "viewClient";
}
Look at ModelAndView that accepts view name.

You can also try this interface Model for this issue:
#RequestMapping(value = "/viewClient", method = RequestMethod.GET)
public String viewClient(Model model) {
ArrayList<SystemUser> systemUsers = clientController.getAllUsers();
model.addAttribute("systemUsers", systemUsers);
return "viewClient";
}
Make sure that in your pom.xml the following dependency exist:
<properties>
<spring.version>4.0.2.RELEASE</spring.version>
</properties>
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-context</artifactId>
<version>${spring.version}</version>
</dependency>

Do not reinitialize ModelAndView Object
#RequestMapping(value = "/viewClient", method = RequestMethod.GET)
public String viewClient(ModelAndView model) {
ArrayList<SystemUser> systemUsers = clientController.getAllUsers();
model.addObject("systemUsers", systemUsers);
return "viewClient";
}
