in case this is still a problem:
you have a space in the property name:

<id name=" empName " column="EMPNAME">

should be

<id name="empName " column="EMPNAME">

Maybe you need to check the place you put the mapping file...

The package location must be the same than the java file...

Plus, you can't have the same attribute be your id and a property at the same time.

I would keep EMPNAME as a property and not make it an ID, it is a really bad candidate for an ID, because you could have two Joe Smith's in your database and then you are in trouble. Always make your ids, as the following

1. a Long
2. named id
3. not a business field in your database, let the database use its native incrementor, whatever that is. This is called a surrogate key, and has no business meaning to it, like EMPNAME does.
