[msgpack][JIRA] Created: (MSGPACK-79) Not able to deserialize derived class object

Not able to deserialize derived class object
--------------------------------------------

Key: MSGPACK-79
URL: http://jira.msgpack.org/browse/MSGPACK-79
Project: MessagePack
Issue Type: Task
Components: Java
Environment: MessagePack - CentOs - Eclipse 3.7
Reporter: muzammil
Assignee: FURUHASHI Sadayuki


public class A
{
private InnerClass obj;
//Some other variables with getters and setters.
// There will be a getter and setter for obj(InnerClass) aswell.
}
class InnerClass
{
//Some variables with getters and setters.
}
class InnerDerivedClass extends InnerClass
{
//some variables with getters and setters.
}

I like to serialize my java class object using Messagepack. My class structure is described above. What I like to do is to create the object for InnerDerivedClass and assign some values to it. Then I would add the object to the Class A as base class object.Now when I serialize and deserialize the Class A object with Messagepack I am not able to get the object as InnerDerivedClass object rather its comes as InnerClass obj. How can I achieve this using MessagePack. I am not using any annotations rather I register each class in the messagepack.

Hi,

I'm trying to reproduce your problem with an attached program, named Main2.java. Its program was created according to your comment. I hit MessageTypeException that is caused by javassist.CannotCompileException.

Is it same as your problem? If not, please tell me your source code.

I have the same issue. MspPack ignores my inheritance.
