Hello Everybody,
I am trying a simple Hibernate program.The programs and stck trace are as follows,

Could you pl. look into it.
Hibernate.cfg.xml

Code:
<!DOCTYPE hibernate-configuration PUBLIC
        "-//Hibernate/Hibernate Configuration DTD 3.0//EN"
        "http://www.hibernate.org/dtd/hibernate-configuration-3.0.dtd">

        <property name="use_sql_comments">true</property>
        <mapping resource="com/wipro/Person.hbm.xml"/>       
    </session-factory>
</hibernate-configuration>


Person.hbm.xml

Code:
<?xml version="1.0"?>
<!DOCTYPE hibernate-mapping PUBLIC

          <property name="firstName" />
            <property name="lastName" />
       
    </class>

</hibernate-mapping>


Code:
package com.wipro;

public class Person {
//every attribute should begin with small letter
   //this is called a pojo in Hibernate.Only properties,stters an getters
   private Integer id;
   private String firstName;
   private String lastName;
   public Integer getId() {
      return id;
   }
   public void setId(Integer id) {

I see that you use HBM2DDL update, which means the tables should have been created when you started the application.

However, there was an error when the schema was generated, and you omitted to add it in the stack trace.

Try setting:

Code:
<property name="hibernate.hbm2ddl.halt_on_error">true</property>

Hi,

My name is Vlad, not Thorben :D

Try with Hibernate 5.2.5 and see if it works.

Thanks Vlad.
Tried with 5.2.3 version of Hibernate jars,but in vain.
The stack trace is the same as in the beginning.

I found the issue. You have a typo:

Instead of:

Code:
<property name="hibernate.hbm22ddl.auto">create</property>


You should have:

<property name="hibernate.hbm2ddl.auto">create</property>

Gotcha!
