I am newbie to Spring MVC.
I was stuck by an error while running my project
Error-The request sent by the client was syntactically incorrect.
I have an entity class PatientInfo.
My jsp page is demo1.
My controller is Patient Controller.
The functionality i want to implement is Inserting values into database.
But i am not able to call my function(add-update2) in controller.

I think the issue is that Spring doesn't know how to deserialize the date your browser client sends when submitting the following input field in
<tr name="tstest">
<td>Date Of Birth</td>
<td><form:input path="dateOfBirth" name="timestamp" value=""/>
<img src="../images/cal.gif" width="16" height="16" border="0" alt="Click Here to Pick up the timestamp">
</td>
</tr>
Spring doesn't know how to take the value that you enter into that field and convert it into a Date object. You need to register a PropertyEditor for that. For example, add the following to your #Controller class
#InitBinder
public void initBinder(WebDataBinder binder) {
SimpleDateFormat sdf = new SimpleDateFormat("MM/dd/yyyy");
sdf.setLenient(true);
binder.registerCustomEditor(Date.class, new CustomDateEditor(sdf, true));
}
Obviously, change the SimpleDateFormat to whatever your client is sending.
On a related note, you're sending a 302 response by sending a redirect
return "redirect:/full-reg";
Remember that request and model attributes only live for the duration of one request. So when your client send the request to full-reg, none of the form input parameters you sent originally exist any more. You should re-think how you do this.
I came across the same error this morning. The problem with my code was that I had declared a variable as an integer in my form binding object but on the actual form I was capturing text. Changing the variable to the correct type worked out for me
This happens when the defined binding does not match to what the user is sending. The most common issues are:
Missing PathVariable declaration
Incomplete PathVariable declaration (for example missing value="variableName")
Wrong data type, such as Sotirios Delimanolis answer above. If the Class of an input parameter cannot be serialized the request is not processable
So, in general, be sure that:
Each PathVariable is declared
A value is assigned that corresponds to value to be match in the path - #PathVariable(value="myVariableName", String myVariable) where the path defines #RequestMapping(value = "/userInfo/myVariableName", method = RequestMethod.GET)
Each class declared for a PathVariable must be serializable.
try with this (with /add-update2 instead of just add-update2) and replace modelAttribute by commandName
<form:form commandName="patientInfo" method="POST" action="/add-update2">
In my case, I try to create an object that has ID and NAME as attributes.
ID is int, NAME is String.
But my js set values like this
ID = '', NAME = 'brabrabra...'
After set ID = 0, problem is fixed.
I had a similar issue recently and solved it by annotating my Date field with the #DateTimeFormat. In your case, you would edit your PatientInfo.java file to:
import org.spring.framework.annotation.DateTimeFormat;
#Column(name = "DateOfBirth")
#Temporal(TemporalType.TIMESTAMP)
#DateTimeFormat(pattern = ${pattern})
private Date dateOfBirth;
Make sure to replace ${pattern} with a string representing the format that will be received (e.g. "yyyy-MM-dd").

I've a problem to insert data to table from my form.
So, I have a two table with relation ManyToOne.
TORDER and TSYSTEM.
I want to insert data to TORDER table via form in my .jsp page. Data for one field is from TSYSTEM table - System Name.
I was able to fill the dropdown list with data from the mentioned table but I have an error message when submitting the form and trying to insert data to TORDER Table.
Do you have any idea why could be wrong here?
My Order model class:

System model:

Controller methods:
#RequestMapping(value="/addOrder", method=RequestMethod.GET)
public ModelAndView addOrder() {
ModelAndView model = new ModelAndView();
Order order = new Order();
model.addObject("orderForm", order);
List<System> systemList = systemService.getAllSystemsName();
model.addObject("systemList", systemList);
model.setViewName("order_form");
return model;
}
#RequestMapping(value="/saveOrder", method=RequestMethod.POST)
public ModelAndView save(#ModelAttribute("orderForm") Order order) {
orderService.saveOrUpdate(order);
return new ModelAndView("redirect:/employee/orderList");
}
Repository methods to get all system names from TSYSTEM Table:
public interface SystemRepository extends CrudRepository<System, Integer> {
#Query("select a.systemName from System a")
public List<System> getAllSystemsName();
}
and finally my .jsp form:
<form:form modelAttribute="orderForm" method="post" action="${saveURL }" cssClass="form" >
<form:hidden path="orderId"/>
<table>
<tr>
<td>System Name</td>
<td><form:select path="systemName">
<form:option value="NONE" label="--- Select ---" />
<form:options items="${systemList}" />
</form:select>
</td>
<td><form:errors path="systemName" cssClass="error" /></td>
</tr>
<tr>
<td><label>Komentarz</label></td>
<td><form:textarea path="comment" cssClass="form-control" id="comment"
title="Dodaj komentarz do zamówienia" /></td>
</tr>
<tr>
<td><label>Data zamówienia</label></td>
<td><form:input type="text" path="orderDate" cssClass="form-control"

<td><button type="reset" class="btn btn-primary">Wyczyść dane</button>
</td>
<td><button type="submit" class="btn btn-primary">Zamów dostęp</button>

</form:form>
and after form submit action i received and error:

Please post SYSTEM model. I think you need change System model with field sysId to Integer type. Because you set repository with model sysId is Integer.

Go back to List of All Employees
</body>
</html>
Here is my controller
#RequestMapping(value = { "/new" }, method = RequestMethod.POST)
public String saveEmployee(#Valid Employee employee,#Valid UserLogin userLogin, BindingResult result,
ModelMap model) {
System.out.println("inside controller");
System.out.println("result>>>> "+result);
if (result.hasErrors()) {
System.out.println("inside controller1111111111");
return "registration";
}
if(!service.isEmployeeSsnUnique(employee.getId(), employee.getSsn())){
System.out.println("inside controller1111111111222222222222222222222");
FieldError ssnError =new FieldError("employee","ssn",messageSource.getMessage("non.unique.ssn", new String[]{employee.getSsn()}, Locale.getDefault()));
result.addError(ssnError);
return "registration";
}
String emp="Emp-"+employee.getId()+"-"+employee.getName();
System.out.println("emp>>> "+emp);
employee.setEmp_id(emp);
service.saveEmployee(employee);
userservice.saveUser(userLogin);
model.addAttribute("success", "Employee " + employee.getName() + " registered successfully");
return "success";
}
So I want to save user_name and password into login table and rest of the data want to save into another table. Is there anyone who can help me how to insert data into two tables. I searched a lot but did not get fruitful result. Any link for this problem is also appreciated. Thanks in advance
You can use entity inheritance. Check this http://www.thoughts-on-java.org/complete-guide-inheritance-strategies-jpa-hibernate/
. Select strategy which fits your reqirements.
hope you can help with this simple noob problem. I creating a Multiple choice question using springboot and thymeleaf.I am getting this error and hope you can help me write the controller method.

Looks like you forgot to add the #Autowired annotation. It's present for the studentDao but not for the subjectDao, resulting in that object not being initialized.
Since I've decided to use same JSP for adding and editing posts, I just pass an attribute "saveUrl" which defines the action for my form in the JSP. Adding a new post works fine, but when editing a post, the object returned to the controller is missing all attributes except for the description.
What am I missing or doing wrong here?
Thanks for help!

UPDATE: I've been experimenting a bit and tried method from HERE, but the object returned to the controler was still empty.
Then I changed the saveURL in JSP to (I read it might be important HERE):
<c:url var="addUrl" value="/secure/postProcess"/>
<form:form modelAttribute="post" action="${addUrl}" method='POST'>
and now the object is filled, only the id is still empty. So there is something probably wrong with the JSP.
