adding .hb.xml vs .class in configuration

hi guys

iam having a doubt that what is the difference between adding a hbm.xml file
vs .class to the configuration object for building the sessionfactory

let me tell you an example

iam having a table named user

Configuration configuration = new Configuration();
configuration.addClass(user.class) ;//statement 1
vs
configuration.addFile("user.hbm.xml") ;// statement 2

what is the difference between statement 1 and statement 2

Hi,

addClass will try to read a mapping from an application resource, using a convention.

Ex.The class foo.bar.Foo is mapped by the file foo/bar/Foo.hbm.xml.

i will be happy if i get some

more techinical information

Have a look at this Hibernate documentation. Specifically, have a look at Section 3.1 which mentions why the addClass method is considered better for creating a Configuration.
