Re: What is the "shared" folder for - if not fot shared classes?

Check, if there is an old version of the gwt-servlet.jar in your classpath.

Hi,

I have a DTO object to transfer some data via RPC from client to server back and forth.
Therefore I though placing this DTO in the /shared folder would be right.

BUT: if I do so, I constantly get an exception.
IF I move the DTO into the /client folder instead, everything works fine.

Why is this? How is the server then able to use the DTO if it is only in the client folder? And why is it not working being placed into /shared?
