@Didier
Of course MyType implements Serializable . It is just a typo in the
example. Sorry.
@Paul
I didn't realized that Class is not GWT-serializable. Thanks for your
remark. I lost pretty much time to find out why I get an exception
during an RPC call
It would have been nice if Class<T> was serializable. I would have
used it to select an appropriate handler at server-side. Anyway I use
instead the canonical class name to map the handler, but the code is
little bit more uggly :-)
I noticed also the a call to class.hashCode() does not give the same
value in the (gwt-compiled)-client and in the (JVM running)-server.
In my attempts to workaround the "unserializability" of Class, I tried
to use the hashCode() value, unsuccessfully...
