I am implementing table per concrete class with unions. I have one Abstract class address and 2 subclasses inheriting from it namely - HomeAddess and OfficeAddess.




This is my address.hbm.xml file


The problem that i am getting on running the code is this :

Exception in thread "main" java.lang.NullPointerException
at com.hibernateexample.inheritance.SaveExample.main(SaveExample.java:47)
Could not parse mapping document from resource address.hbm.xml


Please help me out and tell me where i am going wrong ....

Should

"http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd">

Have a "/" just before the ">"
?
