Did you tried to add the catalog property in the hbm file? <class catalog="world" name="com.java4s.select.Select.java" table="product1"> — Atropo

You should mape the resource in the hibernate.cfg.xml with the full path (of the package):

<mapping resource="com/java4s/select/Select.hbm.xml"></mapping>

Also check that the hbm file is in the same package as the java class file.

EDIT: You have a problem with the mapping of the sno property. Check that hibernate mapping documentation. I guess you should assign a generator to your id field, like for example:

 <id column="sno" name="sno">
      <generator class="assigned"/>
 </id>
