I am working on a Spring-MVC application. I want to implement the forgot password functionality. For that, I am using the secret question method. I have created a JSP page, where I recieve the values like username, secretanswer and then I check if the values exist and then save the new password which the user has given. I am having a problem wiht the JSP page, when I click submit, it shows me some garbage URL. I believe it is some tiny mistake, I am unable to see. Kindly let me know what is going wrong.
Apache tomcat error URL :
HTTP Status 404 - /id=0,%20username=null,%20password=null
Controller function for changing password :
#RequestMapping(value = "/forgotpassword")
public String forgotPassword(Model model){
model.addAttribute("person",new Person());
return "forgotpassword";
}
#RequestMapping(value = "/changepassword")
public String changepassword(#ModelAttribute("person") Person f,Model model){
System.out.println("Did we reach here on submit");
personService.checkAuthenticitiy(f.getUsername(), f.getSecretanswer(), f.getNewpassword());
model.addAttribute("person", new Person());
return "redirect:/forgotpassword";
}
JSP page :
<%# page contentType="text/html;charset=UTF-8" language="java" %>

I am getting Error Response 400 when submitting the form. I have a form which was working fine before i added a drop down list which displays gender to the user from DB. The Drop down is displaying the data correctly but when i am submitting the form i am getting an error. This only happened when i added the drop down list.

HTTP Status 400 – Bad Request
Type Status Report
Description The server cannot or will not process the request due to something that is perceived to be a client error (e.g., malformed request syntax, invalid request message framing, or deceptive request routing).
GenderMap is a map that has the model to display on the screen. The key is Gender class and value is the gender description. The user will select a gender which will be referring to an id in the gender table.
The Entire code is available at - https://github.com/iftekharkhan09/ExpenseCalculator_Nex_Gen/tree/DevBranch
Go to the URL - localhost:8080/ExpenseCalculator/register
Any help will be highly appreciated.
As Razmin said, spring is trying to populate your ModelAttribute (which is of type StaffRegistrationBean) from the body of the POST request (automatically filled by the HTML form).
If you look at the POST request body you will see something like gender: 1. Spring cannot map this Integer to a Gender (even if this Integer simply refers to the id of your Gender..).
You will have to retrieve manually the Gender from your DB, and set it to your Model.
It happens when spring can't populate the ModelAttribute from HTML form.
staffRegistrationBean ModelAttribute can't convert Html's Gender attribute to your Gender object
It worked when enabled "Host" headers in postman
I'm just begin writing an application using Spring MVC. I have 2 entities, District & City. A City has many districts, and each district belongs to a city.
In district.jsp I declare a form, allowing user input of the district name and a selection box to choose the City it belongs to.
The District entity looks like this:
<form:form action="${aAction}" commandName="district">
<table>
<c:if test="${!empty district.districtName}">
<tr>
<td>
<form:label path="id">
<spring:message text="ID"/>
</form:label>
</td>
<td>
<form:input path="id" readonly="true" size="8" disabled="true" />
<form:hidden path="id" />
</td>
</tr>
</c:if>
<tr>
<td>
<form:label path="districtName">
<spring:message text="District Name"/>
</form:label>
</td>
<td>
<form:input path="districtName" />
</td>
</tr>
<tr>
<td>
<form:label path="belongToCity">
<spring:message text="Belong to City"/>
</form:label>
</td>
<td>
<c:if test="${!empty listCities}">
<form:select path="belongToCity" items="${listCities}" itemLabel="cityName" itemValue="id"></form:select>
</c:if>
</td>
</tr>
<tr>
<td colspan="2">
<c:if test="${!empty district.districtName}">
<input type="submit"
value="<spring:message text="Edit District"/>" />
</c:if>
<c:if test="${empty district.districtName}">
<input type="submit"
value="<spring:message text="Add District"/>" />
</c:if>
</td>
</tr>
</table>
</form:form>
In my district controller I declare add action.
#RequestMapping(value = {"/district/add"}, method = RequestMethod.POST)
public String addDistrict(#ModelAttribute("district") District p,Model model, BindingResult result) {
if(result.hasErrors()) {
return "district";
}
this.districtService.addDistrict(p);
return "district";
}
When I run my project, however, it shows a 400 error and the error message: "The request sent by the client was syntactically incorrect."
I suspect my form is wrong somewhere, maybe it is not able to post to controller processing. Could someone help me identify the issue?
Your BindingResult parameter should be adjacent to modelAttribute. Below should be method signature.
#RequestMapping(value = {"/district/add"}, method = RequestMethod.POST)
public String addDistrict(#ModelAttribute("district") District p, BindingResult result, Model model) {
if(result.hasErrors()) {
return "district";
}
this.districtService.addDistrict(p);
return "district";
}
I am working on a Spring-MVc project. I have a single JSP page, with two forms. Both these forms are handled by 2 different controllers, and they have separate database tables, seperate service methods. But I would like to individually select information(notes) which the user is adding and save them. I am posting both of my controller, JSP file, and the error message. Kindly let me know what might be going wrong. Thank you for your time.

}
The crux of the problem is that when I am feeding the correct values for each field the form submission works properly. But when I am giving 'a' or any text value for form field reorderLevel (which is defined as Long) the browser throws this error : The request sent by the client was syntactically incorrect.
I have already defined the following in messages.properties file:
typeMismatch=Could not convert to the required type.
typeMismatch.java.util.Calendar=Please enter date in the dd-MM-yyyy format.
typeMismatch.java.math.BigDecimal=Please enter value in correct format 0.00
typeMismatch.java.lang.Long=Must specify an integer value.
Please help... Thanks
Hi I am new to spring and I am trying to develop a simple portlet that accepts users first and last name and saves it to db using hibernate.
Basically I cannot figure out how the jsps and controllers communicate; I am missing some chunk here.
This is my first controller that needs to be called (where do I mention so?)
package codes.controller;
import javax.portlet.RenderResponse;
import codes.base.User;
import codes.service.UserService;
#Controller(value="SimpleUserController")
#RequestMapping(value = "VIEW")
public class SimpleUserController {
// -- auto-wiring of service dependency
#Autowired
#Qualifier("userService")
private UserService userService;
// --maps the incoming portlet request to this method
#RenderMapping
public String showUsers(RenderResponse response) {
return "home";
}
#ExceptionHandler({ Exception.class })
public String handleException() {
return "errorPage";
}
// -- #ModelAttribute here works as the referenceData method
#ModelAttribute(value="user")
public User getCommandObject() {
return new User();
}
}
Initially I am displaying a home.jsp that will display the form with two input boxes and a submit button.
<%#include file="include.jsp" %>
<portlet:actionURL var="addUserActionUrl">
<portlet:param name="myaction" value="addUser" />
</portlet:actionURL>
<form:form name="home" commandName="user" method="post"
action="${addUserActionUrl}">
<table>
<tr>
<td>First Name:<font style="color: #C11B17;">*</font></td>
<td><form:input path="firstname" /></td>
</tr>
<tr>
<td>Last Name:<font style="color: #C11B17;">*</font></td>
<td><form:input path="lastname" /></td>
</tr>
<table align="right">
<tr>
<td> </td>
<td><input type="submit" value="SUBMIT" /></td>
</tr>
</table>
</table>
</form:form>
This JSP should call the action method in the AddUserController.java:
package codes.controller;
import javax.portlet.ActionResponse;
import javax.portlet.RenderResponse;
import codes.base.User;
import codes.service.UserService;
#Controller(value = "AddUserController")
#RequestMapping(value = "VIEW")
public class AddUserController {
#Autowired
#Qualifier("userService")
private UserService userService;
#RenderMapping(params = "myaction=addUser")
public String showRegisterPage(Model model) {
model.addAttribute("user", new User());
model.addAttribute("users", getUsers());
return "addUser";
}
public List<User> getUsers() {
return userService.getAllUsers();
}
#ActionMapping(params = "myaction=addUser")
public void addBook(#ModelAttribute(value = "user") User user,
BindingResult bindingResult, ActionResponse response,
SessionStatus sessionStatus) {
if (!bindingResult.hasErrors()) {
userService.addUser(user);
response.setRenderParameter("myaction", "users");
sessionStatus.setComplete();
} else {
response.setRenderParameter("myaction", "addUser");
}
}
}
This time this firstname+last name should be saved in the db AND the screen should refresh to show a new form that will have a dropdown with the current users' names in the database and another first name and last name form fields. If you select a username from the dropdown the form fields are populated and you can edit these values and click on UPdate button to save the values in DB. Otherwise you can add a new user to the database using submit button.
addUser.jsp:
<%#include file="include.jsp" %>
<portlet:actionURL var="addUserActionUrl">
<portlet:param name="myaction" value="addUser" />
</portlet:actionURL>
<portlet:renderURL var="homeUrl">
<portlet:param name="myaction" value="Users" />
</portlet:renderURL>
<script type="text/javascript" src="js/userRelated.js"></script>
<form:form name="addUser" commandName="user" method="post"
action="${addUserActionUrl}">
<form:select path="model">
<form:option value="NONE" label="--- Select ---" id="userList" onchange="showHide()"/>
<form:options items="${users}" />
</form:select>
<table>

<td><input type="submit" id="update" value="SUBMIT" />UPDATE</td>

</form:form>
I am hiding and unhiding the SUBMIT/UPDATE button using onchange of dropdown. How do I call different functions in the addUsercontroller depending on the button available?
by updating the action attribute of form element with javascript
