I am new in hibernate and i want to do hibernate annotation and auto generate table in mysql as i submit data.but i have some error like sql grammar.please help me to solve this error.my all code is below..
My Jsp File
<html>
<head>
</head>
<body>
<form action="controller" method="post">
Id : <input type="text" name="id"><br>
First-Name : <input type="text" name="fName"><br>
Last-Name : <input type="text" name="lName"><br>
<input type="submit" value="submit">
</form>
</body>
</html>
This is My Pojo Class
package com.connection;
import javax.persistence.Entity;
import javax.persistence.Id;
import javax.persistence.Table;
#Entity
#Table(name = "csl_emp")
public class Employee {
#Id
private int id;
private String firstName, lastName;
public int getId() {
return id;
}
public void setId(int id) {
this.id = id;
}
public String getFirstName() {
return firstName;
}
public void setFirstName(String firstName) {
this.firstName = firstName;
}
public String getLastName() {
return lastName;
}
public void setLastName(String lastName) {
this.lastName = lastName;
}
}
This is my servler
package com.connection;
import java.io.IOException;
import javax.servlet.RequestDispatcher;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
/**
* Servlet implementation class controller
*/
public class controller extends HttpServlet {
private static final long serialVersionUID = 1L;
/**
* Default constructor.
*/
public controller() {
}
/**
* #see HttpServlet#doGet(HttpServletRequest request, HttpServletResponse
* response)
*/
protected void doGet(HttpServletRequest request,
HttpServletResponse response) throws ServletException, IOException {
}
/**
* #see HttpServlet#doPost(HttpServletRequest request, HttpServletResponse
* response)
*/
protected void doPost(HttpServletRequest request,
HttpServletResponse response) throws ServletException, IOException {
System.out.println("in the controller");
String id = request.getParameter("id");
String fname = request.getParameter("fName");
String lname = request.getParameter("lName");
System.out.println(id + fname + lname);
Employee employee = new Employee();
employee.setFirstName(fname);
employee.setLastName(lname);
employee.setId(Integer.parseInt(id));
EmpDao dao = new EmpDao();
dao.addData(employee);
RequestDispatcher requestDispatcher = getServletContext().getRequestDispatcher("/success.jsp");
requestDispatcher.forward(request, response);
}
}
This is mY dao class
package com.connection;
import org.hibernate.Session;
import org.hibernate.Transaction;
import org.hibernate.cfg.AnnotationConfiguration;
public class EmpDao {
public void addData(Employee employee) {
Session session = new AnnotationConfiguration().configure().buildSessionFactory().openSession();
Transaction transaction = session.beginTransaction();
session.saveOrUpdate(employee);
transaction.commit();
session.close();
}
}
And This is my Configuration File
<?xml version="1.0" encoding="UTF-8"?>

In your configuration file add this property:
<property name="hibernate.hbm2ddl.auto" value="update" />
and also, very useful are these:
<property name="hibernate.show_sql" value="true" />
<property name="hibernate.format_sql" value="true" />
From Hibernate docs
Change your configuration file property as below
<property name="hibernate.hbm2ddl.auto" value="create"/>
instead of
<property name="hbm2ddl.auto">true</property>

Please see if you can help.
I would like to build a small console application executed by tests just of learning Hibernate purposes. Unfortunately, hibernate returns with no data and when a list should be populated by the entities it throws outofindex exception. I assume due to no result coming back. I have been reading the tutorials and questions here, but I cannot find why this happens.
JDBC connection is working well, it is copied from DataGrip.
What other detailed should be checked more? Sorry, I'm totally inexperienced in this world.
Please find the code below.

You need to register entites in the SessionFactory.
You can do it by editing hibernate.cfg.xml by this way:
<session-factory>
...
<mapping class="some.pack.Test" />
...
</session-factory>
You can use Spring to scan a package to add entites, as well. Or, for testing purposes, EntityScanner from here.
Appart that, remove all lines related to the EntityManager and use Session. Remove this:
EntityManager em = sessionFactory.createEntityManager();
Hibernate SessionFactory is not aware of the your entity. You need to add the following resource to the hibernate.cfg.xml file inside the tag replacing the Entity with the correct name of the hbm.xml file.
<session-factory>
.
.
.
<mapping resource="Entity.hbm.xml"/>
</session-factory>
This is my output it shows that I could not get a constructor from org.hibernate.persister.entity.SingleTableEntityPersister. As far as I can tell it has managed to access the log on to the database. The error starts soon after that.

I have search all possibilities but can't find the solution.
I have implemented simplecart to my project.
On clicking the checkout button it went to PayPal which I didn't wanted it to. So I changed the action URL in simplecart.js file to point to my servlet
action = opts.sandbox ? "cart_checkout" :"cart_checkout",
method = opts.method === "GET" ? "GET" : "POST";
It calls the servlet but I get a NumberFormatException in my servlet

You should capture the request that is being sent to your webservice.
In the error you can see that you get a NumberFormatException: null. This suggests that your count String is null.
String count=request.getParameter("ItemCount");
This can happen when ItemCount is not a parameter of your request.
It would be good practice to test count (= "ItemCount" parameter) for null values in your code, so that you can return a nice looking error to your client.
It is because your count variable is null you can avoid it by
String count=request.getParameter("ItemCount");
if(count.length()>0){
int cnt=Integer.parseInt(count.trim());
// other logic
}
else{
//do nothing
}
The cause of the problem is quite straightforward:
int cnt=Integer.parseInt(count);
this is pointed out clearly from your stack trace:
at com.kunal.servlet.CartCheckout.doPost(CartCheckout.java:53)
A simple solution would be to check the count against null, hence change your doPost (..) implementation into:
/**
* #see HttpServlet#doPost(HttpServletRequest request, HttpServletResponse response)
*/
protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
// TODO Auto-generated method stub
String count=request.getParameter("ItemCount");
ArrayList<String> item_detail=new ArrayList<String>();
int cnt= count == null 0 : Integer.parseInt(count);
for(int i=1;i<cnt+1;i++)
{
String name=request.getParameter("item_name_");
item_detail.add(name);
String price=request.getParameter("item_price_");
item_detail.add(price);
String qty=request.getParameter("item_quantity_");
item_detail.add(qty);
}
}
In order to ensure that you'll not encounter the same issue with empty strings, you can check also for empty strings. If using other libraries is an option I would suggest using StringUtils.isNotBlank(..)
then your parsing line becomes:
int cnt= StringUtils.isNotBlank(count) 0 : Integer.parseInt(count);
