I am using gwt-servlet-2.8 RC1 jar on server too. I get 500 Internal Server
Error in Throwable. Also I have not tried Gwt 2.8 RC2, I just updated to
Rc1 for now. Is this issue fixed in Rc2 ? Also I just discovered that issue
goes away if I stop using gwt jackson library which I have started using
after upgrading the gwt version. We are using gwt-jackson, because we wnat
to serialize/deserialize the objects to be used in local storage, this is
the code that I have in one of my DTO(bean) :
public class ResourceBundleBean implements LocallyStorable {
private String someString;
public interface ResourceBundleBeanMapper extends
ObjectMapper<ResourceBundleBean> {};
@Override
public ObjectMapper getMapper() {
if(resourceBundleBeanMapper == null) {
resourceBundleBeanMapper = GWT.create( ResourceBundleBeanMapper.class );
}
return resourceBundleBeanMapper;
}
}
I get exception when the above class "ResourceBundleBean" is returned from
RPC call, and I get "500 Internal Server Error". If I remove the code of
"ResourceBundleBeanMapper " and the getMapper method from this class, then
it starts working and I get the response correctly from RPC call without
any issue. But I need the above code for serialization as I said above. So
I am not sure, why gwt-jackson code is causing the RPC to tjrow 500
Internal server error. Any suggestion would be of great help to me to nail
down this issue. Thanks so much for your response.
Thanks,
Nishant
