Hi, Check that your Hibernate files are placed in the src folder as Dolly had mentioned. We were working on a similar project and got similar error
Also confirm if your RPC service method can return a List as you are getting an error in List coz for our project we colud return only a string object as returning a list gave errors Furthermore, writing a Query in hibernate and GWT is slightly different.I am sending you an example of my server side query,check if you find it useful: Query query=session.createQuery("select Empname from Addmemberserv where Empname like :param1 and Passwd like :param2"); query.setString("param1", input1); query.setString("param2", input2); Addmemberserv is my table name input1 and input2 are my textboxes -- You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.
