Here is my hibernate.cfg.xml file.
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE hibernate-configuration SYSTEM "http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd">

My connection URL, user Name and password are correct. Am trying to connect by using,
public static void main(String args[])
{
SessionFactory sf=new Configuration().configure().buildSessionFactory();
Session ss=sf.openSession();
Transaction tran=null;
UserDetails det= new UserDetails();
det.setDateOfBirth(new Date());
det.setUserName("SomeName");
try
{
tran=ss.beginTransaction();
ss.save(det);
tran.commit();
ss.close();
}catch(Exception e)
{
System.out.println(e.getMessage());
}
}
I use the same code to connect Oracle DB ( after changing the properties in xml ) it works fine, am I missing something specific to postgres ? Please help
"jdbc:postgresql://localhost:5432/TestDataBase. It has a leading double quote that shouldn't be there.
