Property Not Found! same naming convention

I'm here again asking a question, I've tried asking this a while ago (for today) but I've reconstructed my code. So, my problem is that when I click the button to show the details from the database, it show me an error that Property Not Found, I'm confused as to why this error pops out, Here is an example of the error, as you can see it can read the elements in the database when I sysout it, displaying it in the console pic of error

How can I solve this error?

There are some problems in your code
You need to add #Entity and #Table annotations to the Employ
as #KonstantinPavlov suggests.
You need the #Id annotation on userid.
This code is incorrect
String sql_query = "SELECT username, firstname, lastname,
emailid, profession, mobileno, to_char(birthdate, 'MM/DD/YYYY') AS
birthdate, password FROM EmployeeInfo WHERE username = ?";
Query query = session.createQuery(sql_query);
query.setString(0, username);
List<Employee> employees = (List<Employee>)query.list();
You need Employee but you use FROM EmployeeInfo. Hibernate can't convert your projections into Employee (it is need a transformer or the new operator with a constructor in the query). Your query looks like SQL, but you need HQL there.
String hqlQuery = "FROM Employee WHERE username = :userName";
Query query = session.createQuery(hqlQuery);
query.setParameter("userName", username);
List<Employee> employees = (List<Employee>)query.list();
You don't need to build SessionFactory for every request! You need create it using Spring's LocalSessionFactoryBean.
You open a session but don't close it.
You begin a transaction but don't commit or rollback it.

Implementing a java bean into a jsp servlet

I am trying to connect my JSP servlets to a posgress database and I am currently using a java bean class which is playing the role of the middle man. I am experiencing some difficulties with making the registration form successfully store user information into the database. I would really appreciate if you would kindly help me out.
Thanks a lot in advance.

The Java Bean that I use :
public class UserBean {
private int id;
private String username;
private String password;
private String email;
private String firstName;
private String lastName;
private String endDate;
private boolean validated;
public UserBean() {
// Empty constructor
}
public int getId() {
return id;
}
public String getUsername() {
return username;
}
public String getPassword() {
return password;
}
public String getEmail() {
return email;
}
public String getFirstName() {
return firstName;
}
public String getLastName() {
return lastName;
}
public String getEndDate() {

}
public boolean isValidated() {

}
public void setId(int id) {

this.firstName = firstName;

public void setLastName(String lastName) {
this.lastName = lastName;
}
public void setEndDate(String endDate) {
this.endDate = endDate;
}
public void setValidated(boolean validated) {
this.validated = validated;
}
}

Your POJO JavaBean won't magically get populated with the data. It has no connection to the database and no way to get or save data.
You need a controller that fetches data from the DB, creates model objects, and populates them with the data. The controller is also responsible for saving beans
You could write this yourself but it's generally better to use existing ORM frameworks like JPA2, a custom persistence provider API like Hibernate, or something like MyBatis. If you really want, you can hand-roll your controller with direct JDBC calls, injecting the connection from the environment, but that tends to produce a lot of boilerplate code for little benefit even with things like Spring JDBC to help smooth things over.
Some IDEs, like NetBeans and Eclipse, can even auto-generate models and controllers for you, though I've never been very happy with the results (particularly the failure to use a parent-class and generic methods and the lack of any sort of useful error handling).

How to read and pass data from servlet to JSP

A question about read and pass data from servlet to JSP
I want to create a Java EE project. Totally, it has 5 files in this project.
JSP Files: EmployeeInfo.jsp, EmployeeDetails.jsp
Servlets: EmployeeRegistrationServlet, EmployeeSearchServlet
Bean: Employee
EmployeeInfo.jsp file that gets either Employee Id or Employee Information. It have two Submit buttons. If user wants to search an Employee, an ID would be entered and it will call EmployeeSearchServlet, if user wants to add new Employee information, then EmployeeRegistrationServlet will be called with customer information entered. Here is the code:
EmployeeSearchServlet is supposed to search an employee with employee id that was entered by the end user. The job of the servlet is to find particular employee within a collection. Once the employee is found, the flow will be forwarded to EmployeeDetails.jsp.
EmployeeRegistrationServlet is supposed to add employees into a collection where store employees in memory.
If an employee is found, details of employee will be displayed on EmployeeDetails.jsp.
If a new employee is added, details of employee will be displayed on EmployeeDetails.jsp.
Here is my EmployeeInfo.jsp
<body>
<h1 align="center">Employee Information</h1>
<!--Form of find employee by employeeID -->
<form action="EmployeeSearchServlet" method="POST">
<fieldset>
<legend>Find Employee</legend>
Employee ID: <input type="text" name="findEmployeeID"><br>
<input type="submit" name="findEmployeeSubmit" value="Find Employee">

here is my EmployeeRegistrationServlet

employees = new HashMap<String,Employee>();
Employee newAdd = new Employee(employeeID, firstName, lastName, email, phone, hireDate, managerID, departmentID);
request.getRequestDispatcher("../../../../WebContent/EmployeeDetail.jsp").forward(request,response);
}
}
My question is how to use EmployeeDetail.jsp read bean object passed from EmployeeRegistrationServlet? And how to Find an employee by searching the employee ID?
Please give me some suggestions. Thanks a lot.

My question is how to use EmployeeDetail.jsp read bean object passed from EmployeeRegistrationServlet?
You need to set the Object in request / session attribute to be available to forwarded jsp
how to Find an employee by searching the employee ID?
depends on your data store, for example if you are using mysql you need to use jdbc and query to get record by id
See
example on jsp wiki
servlet wiki

You have many choices. I would encourage you to look at this tutorial, and consider using <jsp:useBean id="myObject" class="myClass" scope="session"/> tags:

I want the user to be able to add more rows delete existing rows on button click. Can anyone tell me how to achieve this. See below my controller and jsp code. On clicking add I want to add 3 more rows selecting check box and clicking delete row should delete the row. i want the the added columns to be binded
I am very new to jQuery is this possible without jQuery. If not please tell me in detail how to achieve this using jQuery

Even though this thread is older, For the benefit of others who is in need of this.
Let me explain with a minimal code and User example with firstName, email, userName and gender fields so that people won't get confused with bigger code.
Consider you are sending 3 empty users in usersList from controller this will creates 3 empty rows. If you inspect/view page source you will see
Rows(<input> tags) with different id's like list0.firstName
list1.firstName
Rows(<input> tags) with different names like list[0].firstName
list[1].firstName
Whenever form is submitted id's are not considered by server(added for only for helping client side validations), but name attribute will be interpreted as request parameter and are used to construct your modelAttribute, hence attribute names are very important while inserting rows.
Adding row
So, How to construct/append new rows?
If i submit 6 users from UI, controller should receive 6 user object from usersList. Steps to achieve the same is given below
1. Right click -> view page source. You will see rows like this(you can see *[0].* in first row and *[1].* in second row)
<tr>
<td><input id="list0.firstName" name="list[0].firstName" type="text" value=""/></td>
<td><input id="list0.email" name="list[0].email" type="text" value=""/></td>
<td><input id="list0.userName" name="list[0].userName" type="text" value=""/></td>
<td>
<span>
<input id="list0.gender1" name="list[0].gender" type="radio" value="MALE" checked="checked"/>Male
</span>
<span>
<input id="list0.gender2" name="list[0].gender" type="radio" value="FEMALE"/>Female
</span>
</td>
</tr>
<tr>
<td><input id="list1.firstName" name="list[1].firstName" type="text" value=""/></td>
<td><input id="list1.email" name="list[1].email" type="text" value=""/></td>
<td><input id="list1.userName" name="list[1].userName" type="text" value=""/></td>
<td>
<span>
<input id="list1.gender1" name="list[1].gender" type="radio" value="MALE" checked="checked"/>Male
</span>
<span>
<input id="list1.gender2" name="list[1].gender" type="radio" value="FEMALE"/>Female
</span>
</td>
</tr>
Copy first row and construct a javascript string and replace '0' with variable name index. As given in below sample
'<tr>'+
'<td><input id="list'+ index +'.firstName" name="list['+ index +'].firstName" type="text" value=""/></td>'+
'<td><input id="list'+ index +'.email" name="list['+ index +'].email" type="text" value=""/></td>'+
...
'</tr>';
Append the constructed row to the <tbody>. Rows get added in UI also on submission of form newly added rows will be received in controller.
Deleting row
Deleting row is little bit complicated, i will try to explain in easiest way
Suppose you added row0, row1, row2, row3, row4, row5
Deleted row2, row3. Do not just hide the row but remove it from the
DOM by catching event.
Now row0,row1,row4,row5 will get submitted but in the controller your
userList will have 6 user object but user[2].firstName will be null
and user[3].firstName will be null.
So in your controller iterate and check for null and remove the
user.(Use iterator don't use foreach to remove user object)
Posting code to benefit beginners.
