in one post i came across the following piece of information:

When you are using HQL the query parser will ignore the mapping document(*.hbm.xml). So when you are executing a HQL you have to specify the value in the Database.

if the query paser ignores hbm files then what is the requirement of hbm files in application using hibernate.

you either misread the post or the post mis-spoke.

the hql parser ignores certain pieces of information from the metadata. mainly it ignores metadata-defined fetching strategies; opting instead that the user explicitly define them in the HQL statement (join fetches).
