Hi Sri, I am using Hibernate to access the database and used the example from http://code.google.com/webtoolkit/articles/using_gwt_with_hibernate.html. When i create a hibernate session from rpc servlet, it throws error "INetAddress is a restricted class". :(
Even i tried GiLead library, even in that when i tried to create a hibernate session and set it to persistance manager it throws the same error. :( regards, Muthu On Nov 18, 12:25 pm, Sripathi Krishnan <sripathi.krish...@gmail.com> wrote: > If you are using Google App Engine, you cannot access databases even @ > server side.
