I am new to java and am trying to write an application using spring-mvc and hibernate.
I am getting the error
"Caused by: java.lang.IllegalStateException: Neither BindingResult nor plain target object for bean name 'command' available as request attribute"
in a JSP file when I try to populate a dropdown list with elements from a database

Set the modelAttribute property on your form to the correct value.
<form:form modelAttribute="" >...
In your case it should be "mtMetal".
Always name your model attributes when adding them to your model, so that you know what to set in your form.

I try to write simple Spring MVC CRUD webapp and I got a problem updating my rows. I have a table with some users and I can edit any of them clicking "Edit" button in the table (look at the picture). Then I can change its fields in a form, but when I click "Edit" under the form, the id of user entity, that is conveyed to the addUser() method, is 0, though, when I got the entity from db, it wasn't. Also "createdDate" field becomes null. I can't find out the reason of it, so I need some help... This is my code and the picture with my app:

I have no idea where the problem may be, so if you need more code, I'm ready to write it. Thanks
I solved this. I had to add <form:hidden path="id" /> to the id input field. I suppose I need to do the same with createdDate field.
I want to associate checkbox id(which is dynamically created) with text box.
For Example : If 5 check boxes are appearing along with 5 text boxes, i want that the check box i select the corresponding value will get update in database.
Problem : if 5 check boxes are appearing on jsp page and if i select 2, 4 and 5th checkboxes, then corresponding text box values i.e. 2,4 and 5th value should be inserted in database.
But in my case checkboxes are inserted correctly but values are not inserting. it is inserting like for 2nd check box ---> it is selecting first textbox,
and for 4th checkbox ----> it is selecting 2nd textbox value and for 5th checkbox it is selecting -----> 3 textbox value.
I known that it is because of this code : Here Attribute List contains three selected checkBox but attribute value contains 5 elements. and it will pick only three.
List<Object[]> inputList = new ArrayList<Object[]>();
for (int i = 0; i < qualification.getAttributeList().length; i++) {
Object[] tmp = {newCompanyId,qualification.getAttributeList()[i],qualification.getAttributeValue()[i]};
inputList.add(tmp);
Can anyone please let me know ho to solve the issue. Please find the attached pics.

PreparedStatement ps = null;
ps=conn.prepareStatement("insert into tab values(?,?");
ps.setString(1,eb.getEmp_id());
ps.setDate(2,eb.getLoginDate());

}
In TimseSheetProcess.jsp:
<%#page import="com.eis.Dao.TimseSheetDao"%>
<jsp:useBean id="obj" scope="session" class="com.eis.bean.EmployeeBean"/>
<jsp:setProperty property="*" name="obj"/>
<% out.print("You are in loop");

if(status>0) {
out.print("You are successfully registered");
response.sendRedirect("timsesheet.jsp");
}
else{
out.print("Error");
}
%>
Thanks
Your are setting the id and the date at the same parameterindex "1" of the preparement statement! That's wrong ....
ps.setString(1,eb.getEmp_id());
ps.setDate(1,eb.getLoginDate());
I am quite new to spring framework and I'm stuck with the following issues:
I am trying to insert multiple records on a single post request using Spring MVC 3.0
I successfully bound the List object and it is populating on JSP and when I submit the
form the request is reaching on the controller method(post) but the returned object does not contain proper values, its printing null.
My code is as follows:
form.jsp
<%# page language="java" contentType="text/html; charset=ISO-8859-1"
pageEncoding="ISO-8859-1"%>
<%#taglib uri="http://www.springframework.org/tags/form" prefix="f"%>
<%#taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c"%>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1">
<title>Insert title here</title>
</head>
<body>
<f:form commandName="teamBean" method="post">
<f:input path="players[0].fname" />
<f:input path="players[0].lname" />
<f:input path="players[0].phone" />
<f:input path="players[0].email" />
<input type="submit" value="submit" />
</f:form>
</body>
</html>
DynaminFormController.java
#Controller
#RequestMapping("/form")
public class DynaminFormController {
List<Player> players = new ArrayList<>();
#RequestMapping(method = RequestMethod.GET)
public String getForm(Map<String, TeamBean> map) {
TeamBean teamBean = new TeamBean();
players.add(new Player("dd", "dd", "dd", "dd"));
players.add(new Player("cc", "cc", "cc", "cc"));
teamBean.setPlayers(players);
map.put("teamBean", teamBean);
return "form";
}
#RequestMapping(method = RequestMethod.POST)
public String postForm(TeamBean teamBean) {
System.out.println("DynaminFormController.postForm()");
System.out.println(teamBean);//printing null
return "view";
}
}
TeamBean.java
public class TeamBean {
private List<Player> players;
public List<Player> getPlayers() {
return players;
}
public void setPlayers(List<Player> players) {
this.players = players;
}
#Override
public String toString() {
return "TeamBean [players=" + players + "]";
}
}
Player.java
public class Player {
private String fname;
private String lname;
private String phone;
private String email;
public Player(String fname, String lname, String phone, String email) {
this.fname = fname;
this.lname = lname;
this.phone = phone;
this.email = email;
}
///getters setters...
#Override
public String toString() {
return "Player [fname=" + fname + ", lname=" + lname + ", phone="
+ phone + ", email=" + email + "]";
}
}
You need #ModelAttribute on you Post Method
#RequestMapping(method = RequestMethod.POST)
public String postForm(#ModelAttribute("teamBean") TeamBean teamBean) {
System.out.println("DynaminFormController.postForm()");
System.out.println(teamBean);//printing null
return "view";
}
I have resolved my issue, the problem was with spring's input tag ,i don't know why it was not working but just replace the f:input with html's input tag,though u may not get the populated values from controller but it's fine.
<f:form commandName="teamBean" method="post">
<tr>
<td><input class="dy" name="players[0].fname" /></td>
<td><input class="dy" name="players[0].lname" /></td>
<td><input class="dy" name="players[0].phone" /></td>
<td><input class="dy" name="players[0].email" /></td>
</tr>
<input type="submit" value="submit" />
</f:form>
I am using spring MVC 3. I have been trying to access the attributes of the uploaded file but I keep getting the following error message. I can access the other fields of the form that is posted but I can't access the uploaded file.
nullhandleForm - Failed to convert property value of type 'java.lang.String' to required type
'org.springframework.web.multipart.commons.CommonsMultipartFile' for property 'file';
nested exception is java.lang.IllegalStateException:

this.gendre = gendre;
}
public String getSongName() {
return songName;
}
public void setSongName(String songName) {
this.songName = songName;
}
}
The controller
#Controller
public class AdminController{
#RequestMapping(value = "/admin", method = RequestMethod.GET)
public String showAdmin(){
return "admin/index";
}
#RequestMapping(value = "/admin/upload-songs", method = RequestMethod.GET)
public String showContacts(Model model) {
model.addAttribute(new HandleForm());
return "/admin/upload";
}
#RequestMapping(value = "/admin/upload-songs", method = RequestMethod.POST)
public String doForm(#ModelAttribute(value = "handleForm") HandleForm handleForm, BindingResult result, Model model){
if(result.hasErrors()){
String stringList = null;
List<FieldError> errors = result.getFieldErrors();
for (FieldError error : errors ) {
stringList += error.getObjectName() + " - " + error.getDefaultMessage() + "\n";
}
model.addAttribute("Response", stringList);
//model.addAttribute("songname", handleForm.getSongName()); works fine
//model.addAttribute("filename", handleForm.getFile().getOriginalFilename()); throws an error..?
}
return "/admin/upload";
}
}
Any help would be much appreciated. Thanks in advance
do you need to add the enctype to the form declaration?
enctype="multipart/form-data"
Also make sure you have the resolver for Multipart file in your dispatcher servlet
<bean id="multipartResolver"
class="org.springframework.web.multipart.commons.CommonsMultipartResolver">
<!-- one of the properties available; the maximum file size in bytes -->
<property name="maxUploadSize" value="100000"/>
</bean>
