Re: GWT error "no instantiable subtypes" with interface in RPC method with 1 known concrete class?

Are the classes visible to GWT? I don't see .client. or .shared. in the package com.ited.lang.transporttoken.TransportTokenResponse so double check the source entries in your gwt.xml file

Sorry for being impatient ;)..

Anybody an idea ? (interface not allowed at all in RPC method calls? )

No idea. Might be a bug... or intended ;-) Maybe GWT explicitly searches for a class that implements TransportTokenResponse<ProductDto> and does not care about your <T> implementation.

Does it work if you add

SimpleTransportTokenResponse<ProductDto> dummyMethod();

to your service?
