Hi, I am trying to generate POJOs using hbm2java. I downloaded the hibernate extensions package and after setting the appropriate class path, I am trying to execute the hbm2java file giving the mapping file as input. When I do that it throws me net. sf. hibernate. MappingExpcetion. I looked into the downloaded jar file and the source of the file. But it is not showing that particular file in the package. Can someon help me out in downloading the net.sf.* package. I tried searching google but in vain. I am trying from the past so many days. Any help would be appreciated.
