Hibernate - Issue saving generic object to database

I have below method to save an object to database using Hibernate but I keep getting "org.hibernate.MappingException: Unknown entity: java.lang.Class" error while saving.

System.out.println("transientInstance:" + transientInstance);
System.out.println("transientInstance:" + transientInstance.getClass());  
getSession().save(transientInstance);  

System.out.println statements are printing below information.
transientInstance:class com.mypkg.pojo.Details
transientInstance:class java.lang.Class

Any idea what could be wrong please?

Thanks,

You're trying to store a java.lang.Class object, rather than an entity instance. transientInstance is not an entity instance. It's com.mypkg.pojo.Details.class.

The error is in code that you don't show, before the call to save().
