[PATCH] Can't add custom Hessian serializers to the client
----------------------------------------------------------
Key: CAY-1629
URL: https://issues.apache.org/jira/browse/CAY-1629
Project: Cayenne
Issue Type: Improvement
Components: ROP
Affects Versions: 3.1M4
Environment: Mac 10.6
Reporter: John Huss
Priority: Minor
Attachments: client_custom_serializers_patch.txt
There isn't any way to register custom Hessian serializers to the client in an
ROP setup. They can be registered with the server by doing this:
public class SampleServlet extends ROPHessianServlet {
public void init(ServletConfig configuration) throws ServletException {
super.init(configuration);
getSerializerFactory().addFactory(new MySerializerFactory());
}
}
The attached patch saves and exposes a reference to the serializerFactory on
the client so that the same thing can be done there as well, like so:
ClientRuntime clientRuntime = new ClientRuntime(...);
((HessianConnection)
clientRuntime.getConnection()).getSerializerFactory().addFactory(new
MySerializerFactory());
In either case these custom serializers will not be reflected when using the
static methods in HessianUtil since those factories are completely internal.
This could be considered an existing bug since the server already supports
adding custom factories. Perhaps the better solution would be to make the
CLIENT_SERIALIZER_FACTORIES and SERVER_SERIALIZER_FACTORIES variables
modifiable, but that feels ugly.
For the time being though, the patch provides some essential functionality that
is missing.
