[hibernate-dev] annotation for adding column comments for hbm2doc

[Prasanna Kothandaraman]

Hi all,

Got the breakthru in problem I narrated in my earlier mail. Its because of
my ignorance ;-).

Column annotations are controlled via "XProperty property". Soon I should
start thinking about presentation layer modifications.

Please let me know if you have any inputs.

Regards,
Prasanna
