    Problem: Seam Generate Entities !

    Prathamesh Gaddam Novice
      Hi,

      I hv used "Seam Genetrate Entities" to reverse engineer from database. The relavant .xhtml and xml with .java files are generated.

      However in some of the auto-generated java codes (bean), the datatype of the attributes/class variables is "double" and where as the datatype of the respective column in the database table is as "float".

      The earlier generated (and enchanced code) is same as I hv generated newly. But the newly genarated one is not working and where as the old one is still working fine.

      Kindly suggest how to deal with it?

      I guess because of this the deployment if failing, with followig error message.
