Hello all, first of all I like to thank of all you guys - MINA is a really excellent piece of software! After using it for more than a year I am fascinated how easy it is to implement complex client-server applications without much effort! But now to my questions concerning the object serialization features.
I was wondering if the ObjectSerializationCodecFactory may be used safely in production environments when the only data that is transferred between clients and the server are objects (i.e. a custom codec doesn't seem to be necessary to me)? The reason I am asking is because the JavaDoc description of the class states that the "codec is very useful when you have to prototype your application rapidly without any specific codec". This sounds as if it should only be used for testing purposes but not within a production environment. Furthermore I was wondering why the decoder and ByteBuffer.getObject() use a classloader to check, if the transferred class is available on the receiver's platform (deserialization will fail without the check in every case when the class to be deserialized isn't available to the receiver, won't it?). I am developing a client application using Eclipse RCP and class loading is a bit difficult here because the OSGi platform is used to control class loading in the Eclipse platform. I wasn't able to use the ObjectSerializationCodecFactory out of the box because of NoClassDefFound errors produced by the Eclipse class loaders (which are not present if one simply uses the ObjectInputStream without specifying a separate classloader). Object serialization works find without the additional class checks, so I created a mere copy of the decoder and the ObjectSerializationCodecFactory to prevent the usage of explicit classloaders - but are there any risks involved in doing so which I don't see and you are aware of? My last question concerns the different default max object sizes in the en- and decoder implementations - is there a reason why the encoder may encode objects up to Integer.MAX_VALUE, but the decoder refuses anything above 1MB? Are you aware of some known issues concerning memory consumption if I set the max object size of the decoder to Integer.MAX_VALUE as well?
