Short Answer : Just disable Google App Engine for your project, and things should start working. Its a setting in the Google Eclipse Plugin.
Long Answer : GWT and Google App Engine (GAE) are two separate projects, and you don't have to use them together. If you enable GAE - you cannot use any other database. If you disable GAE and only use GWT - you can use whatever you want on the server side. Client side restrictions still apply. Many, many users have accidentally enabled GAE (or is it enabled by default?) and have faced this issue, so this isn't new. --Sri 2009/11/18 Muthukumaran Balan <nbmku...@gmail.com> > 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.
