Hi Poonam, Apart from making sure your Hibernate and applicationContext.xml configurations are correct, I think another major cause for the stack trace you're seeing is that you're mixing server-side Java code with client-side GWT code. It's important to recall that GWT code gets converted into equivalent JavaScript, therefore you can't directly use server-side Java concepts in GWT code and expect them to work as they would in a Java runtime.
That said, there is a set of emulated JRE types supported in GWT. You can check out the link below to the types that are supported in the emulated JRE. Emulated JRE: http://code.google.com/docreader/#p=google-web-toolkit-doc-1-5&s=google-web-toolkit-doc-1-5&t=RefJreEmulation Vitali's suggestion of getting your server-side properly configured without introducing GWT at first, and then creating the client-side using GWT and integrating with the server-side using GWT RPC sounds like a sound approach if you're just getting started. Hope that helps, -Sumit Chandel On Tue, Mar 10, 2009 at 12:26 AM, Vitali Lovich <[email protected]> wrote: > This is more a Hibernate than GWT issue.
