I have a few Java classes that implements Serialization, and corresponding AS objects (self-generated by GAS) that implements IExternalizable.
There is no problem receiving objects from the server, but when I try to send objects to the server - it throws an exception:
[BlazeDS]Class 'xxx' must implement java.io.Externalizable to receive client
IExternalizable instances. flex.messaging.io.SerializationException: Class 'xxx' must
implement java.io.Externalizable to receive client IExternalizable instances.
Really I must implement Externalizable to send objects to Java server?!
Actually, I don't have to implement Externalizable and even not Serializable. Instead I just have to specify, on the flex side that it is a remote class with alias that points to the full java class path. I should also make sure that the properties names (or getters and setters) are equal to the java object properties names. Finally, I should make sure that the object/properties types are matched or converted well (numeric java objects to Number in Flex etc.).
