Creating .hbm.xml file automatically

Steps you need to do

1. Get Middlegen
2. Change the build.xml according to the database you chose
3. You can mention which tables you want to generate using the option table in the build.xml file(just closely look at the different ant taks in it)
4. run the ant script using ant middlegen, this will open up a gui in which click hibernate tab, and select the tables you want to generate.
5. Finally click generate, the files will be loaded into the hibernate directory
Let me know if you have questions

You can do this very easily (and using GUI) using Hibernate Tools.
