Non-Netty client - Any help please, nearly there!

[skhalid]

Hi Trustin,

Apologies for the delay in getting back to you - we need to get this
resolved as soon as possible for our project delivery. Thanks for resolving
the mystery of the magic header not coming in due to compatibleencoder just
sending it once - that's probably the issue. We are dropping
serialization/object communications support in favour of JSON/String based
communications because it is more compact as compared to binary/serialized
bytes (also since Android has it's own jvm called dalvik, objects serialised
in that environment may/may not deserialise properly in another
environment). But just to continue problem resolution of the serialisation
stuff:

We've now changed the code to :


ByteArrayInputStream bais = new ByteArrayInputStream(ary);
        ObjectDecoderInputStream ois = new ObjectDecoderInputStream(bais);
        User c = null;
        try {
			Object myObject = ois.readObject();
			System.out.println("Object of class is " +
myObject.getClass().toString());
			c = (User)myObject;
		} catch (ClassNotFoundException e) {
			e.printStackTrace();
		}



And also used the ObjectEncoder/ObjectDecoder on server - but here is what
we are getting now in client :

Exception in thread "main" java.io.StreamCorruptedException: Unsupported
version: 0
	at
org.jboss.netty.handler.codec.serialization.CompactObjectInputStream.readStreamHeader(CompactObjectInputStream.java:57)

Have no idea why this is occurring...



The reason we can't use Netty classes (or more importantly, the Netty Client
code)  is because the dalvik jvm does not fully support all JDK
classes/packages - so far we've discovered the java.lang.management.*
package. We can't proceed beyond the point where the netty client code in
Android tries to reference the TimeBasedUuidGenerator class/creation. There
*might* be other classes not working with Android, but we need a solution on
how to avoid the problem in TimeBasedUuidGenerator (maybe somehow provide
another version of TimeBasedUuidGenerator - so this is not essentially
recompiling, but extending/adding more code at runtime). For a list of what
is available in android jvm:
