I am making a Spring MVC application, when I fill out a table in jsp and click the "save" button, the data is not saved, an error is generated: Request processing failed; nested exception is org.springframework.dao.DataIntegrityViolationException: could not execute statement; SQL [n/a]; constraint [null];
here is the output I have on the console: Pass_in_trip [key=null, trip=Trip [trip_no=0, comp=Company [id_comp=0, name=null], plane=null, town_from=null, town_to=null, time_out=null, time_in=null, passInTrips=[]], passenger=Passenger [name=null, passengerId=0, passInTrips=[]], place=6f, date=null]
and at the input to the insert method, my object is empty, tell me what I'm doing wrong?

So, in the above examples, I want to send the value selected from the dropdown list to my controller.
Im my html, if I select any value from the dropdown and press 'Go' it shows me the whole database for all the 3 agents but not the particular one that I selected.
Any suggestions how to curb this error.
I have tried searching for a solution on internet but they were using JSP which I haven't studied yet.
You can get the value submitted from the view to the controller in many ways. As you have a single value is passed from View to Controller you can use
#RequestParam
Your viewMission may look like this
#GetMapping("/viewMission")
public String viewMission2(#RequestParam#RequestParam(name = "agents", required = true) String agents, Model model) {
List<Mission> mission1 = database.getMissions(String agents);
model.addAttribute("missionList", mission1);
return "view_missions";
}
You have to pass the selected value to your query to filter the list based on the selected agent and your query will be
public List<Mission> getMissions(String agents) {
MapSqlParameterSource namedParameters = new MapSqlParameterSource();
String query = "SELECT * FROM missions WHERE agent ='" + agent +"'";
BeanPropertyRowMapper<Mission> missionMapper = new BeanPropertyRowMapper<Mission>(Mission.class);
List<Mission> missions = jdbc.query(query, namedParameters, missionMapper);
return missions;
}
Which will filter the list.
how can i pass two parameters using ajax from two different textboxes to another page.
which function should i use to do this.

please Help me.
Thanks.
The problem in your code is caused by this line in the HTML:
<td><input type="text" name="feeid"
"which function should i use here?" ="sendInfo(this.value)"></td>
Your sendInfo(str, stri) JavaScript function expects two parameters, but you are only passing in one. Pass in a value for stri and you should be good to go.
I have three fields department_Id,department_Name,department_location in departmentForm act as a model object in this model form.
I have use annotation to validate the fields. Now, I want to only use two fields in different jsp page say create.jsp and one field in different jsp page say getDepartmentById.
When I press submit button of create.jsp, validation is happening but after providing correct information its not submitted cause in this page.
I haven't give one field department_Id which is auto generated by my DAO layer. So, please help me, how to reject this value to execute my create.jsp page for successfully creating department in database.
When I printed the BindingResult object, it shown as follow:
Field error in object 'departmentForm' on field 'departmentId': rejected value [null];
codes [NotEmpty.departmentForm.departmentId,NotEmpty.departmentId,NotEmpty.java.lang.String,NotEmpty];
arguments [org.springframework.context.support.DefaultMessageSourceResolvable:
codes [departmentForm.departmentId,departmentId]; arguments [];
default message [departmentId],org.hibernate.validator.constraints.NotEmpty.message},
[Ljava.lang.Class;#4fc4a198,[Ljava.lang.Class;#764d2b11];
default message [may not be empty]`
This is how I coded in controller:
#RequestMapping(value = "/createDepartment", method = RequestMethod.POST)
public String createEmployee(#Valid DepartmentForm departmentForm,
BindingResult bindingResult, Map<String, DepartmentForm> model)
throws Exception {
if (bindingResult.hasErrors()) {
System.out.println(bindingResult);
bindingResult.reject(departmentForm.getDepartmentId());
return "departmentForm";
}
System.out.println("mr ankur jadiy");
model.put("departmentForm", departmentForm);
departmentForm.setUpdateStatus('A');
if (departmentForm.getUpdateStatus() == 'A') {
departmentServiceImpl
.actionDecider(convertDeptFormToDeptBO(departmentForm));
}
return "Success";
}
my DepartmentForm code is as follow:
package com.nousinfo.tutorial.model;
import javax.validation.constraints.Size;
import org.hibernate.validator.constraints.NotEmpty;
public class DepartmentForm {
#NotEmpty
#Size(min = 1, max = 20,message="")
private String departmentId;
#NotEmpty
private String departmentName;
private String departmentLocation;
private Character updateStatus;
public String getDepartmentId() {
return departmentId;
}
public void setDepartmentId(String departmentId) {
this.departmentId = departmentId;
}
public String getDepartmentName() {
return departmentName;
}
public void setDepartmentName(String departmentName) {
this.departmentName = departmentName;
}
public String getDepartmentLocation() {
return departmentLocation;
}
public void setDepartmentLocation(String departmentLocation) {
this.departmentLocation = departmentLocation;
}
public Character getUpdateStatus() {
return updateStatus;
}
public void setUpdateStatus(Character updateStatus) {
this.updateStatus = updateStatus;
}
}
and my create.jsp is

What the error says is that you're missing value for departmentId, which is not surprising since you defined it as
#NotEmpty
#Size(min = 1, max = 20,message="")
You don't really need to validate departmentId if it's autogenerated by your code. You probably should remove it from the DepartmentForm, especially since it's not in the form, or at least make it optional.
You can make it mandatory in your business object, but the form backing object should reflect what's in the form.
update
If departmentId is a database-generated id, you should set it as disallowed in your controller's InitBinder:
#InitBinder
public void initBinder(WebDataBinder binder) {
binder.setDisallowedFields(new String[] { "departmentId" });
}
I trying to populate the dropdown list when page was loaded.But it is not loaded in UserPage.jsp from Controller.on submit method and also wrote referencedata method.
Controller:-
public ModelAndView onSubmit(HttpServletRequest request,
HttpServletResponse response, Object command, BindException errors)
throws Exception {
log.info("onSubmit handleRequest method"
+ request.getParameter("username"));
System.out.println("onSubmit handleRequest method"
+ request.getParameter("username"));
String username = "", password = "";
username = request.getParameter("username");
password = request.getParameter("password");
UserBean ubean = null;
System.out.println("After shownform method called");
HttpSession session = request.getSession(true);
try {
ubean = userservice.chkUsername(username, password);
System.out.println("Information" + ubean.getUsername());
} catch (DataException ex) {
ex.printStackTrace();
// throw ex;
}
session.setAttribute("User", ubean);
EmpPersonalBean personalBean = new EmpPersonalBean();
return new ModelAndView("jsp/UserPage", "EmpPersonalBean", personalBean);
}
protected Map referenceData(HttpServletRequest request) throws Exception {
log.info("UserDBBoardController======================referenceData");
Map referenceData = new HashMap();
List deparementList = new ArrayList();
deparementList = userservice.getDeparmentList();
referenceData.put("deparmentList", deparementList);
return referenceData;
}

return deptname;
}
public void setDeptname(String deptname) {
this.deptname = deptname;
}
}
And also attached displaying dropdown list in the userpage.sjp
Please help me.How to resolve the issue.
You also need to specify itemLabel and itemValue attributes in <form:options/> tag.
UPDATE
Replace this line in your jsp page. I think it should resolve your problem.
<form:options items="${deparmentList}" itemLabel="deptname" itemValue="deptcode" />
Hope this helps you. Cheers.
<td>Department</td>
<td><form:select path="deparment">
<form:option value="NONE" label="--- Select ---" />
<c:forEach var="department" items="${deparmentList}">
<form:option value="${department}" label="${department}" />
</c:forEach>
</form:select>
</td>
ModelAndView mav = new ModelAndView("viewName");
mav.addObject("deparmentList", deparementList);
return mav;
return modelAndView object.
