Re: SerializationException with List

Did you already try ArrayList instead of List?

I've just managed to update my GWT (2.4) and I'm having problems with
my RPCs. Every time I try to send a List object it says the item can
not be deserialized. I single stepped through it and it comes out as a
SerializationException which GWT wraps in a
IncompatibleRemoteServiceException.

The Lists are of pojo objects that do implement Serializable and have
always been deserializable before. I thought that it might be related
to mismatching GWT jars so I tried changing them. When I use the gwt-
servlet.jar (version 2.2.) it says
"Response can not be deserialized".
When I use a different version of that jar it says "
Response can not be deserialized expected version 7 but server had 5"
or something like that which leads me to believe my jars are correct.


But for some reason I can't deserialize a list. I've seen a lot of
postings on this subject but no concrete answers. I'm not running in
hosted mode, just using raw tomcat. I can't figure out what's wrong.
Can anyone recommend some other things I should check? Or a way to
debug so I know what versions are being used? The System no longer
complains about the versions when I use the "correct" jars but if the
versions are correct can anyone suggest a reason why the List object
can not be deserialized?
Any help would be great, thanks.
