<generator class="increment"/>

waqasqadri,
I could not reproduce this at my end using mySql. Even after changing the assigned column to increment, the base table structure remained the same and I did not get any errors.
Looking at your error messages, it looks like ‘Detail.hbm.xml ‘ could not be located. Double check the path given in the hibernate-mapping.
You could also refer to the following links
1. http://qaix.com/java-programming/341-696-hibernate-org-hibernate-mappingexception-error-reading-resource-read.shtml
2. http://forums.sun.com/thread.jspa?threadID=665749
If the above solutions do not work, I would suggest you to cross post to hibernate forums also.

None of the links solved my problem. It looks a bit strange error, any how i also cross posted.
