复杂对象序列化

Question

I've got a few questions on the topic of serializing complex objects and writing them to a file.

First, I've got a few objects which are connected to each other, in more precise ways I have an object which holds another objects in a list which are also holding another object. so, the overall architecture of the object I want to write to the file looks as follows:

ComplexObject
-> holds List of NotSoComplexObject(s)
--> every NotSoComplexObject
---> holds a SimpleObject

all of the objects implement the Serializable interface.

if I try to serialize the ComplexObject and write it to a file I got no specific Exception as the Exception.getMessage() method returns NULL (so, it's an Exception that is being thrown, but it's not clear which Exception it is).

Is there a way to achieve the ComplexObject to be serialized and stored in a file?

Answer 1

The exception itself tells you what type it is. I assume its NotSerializableException.

In Java you might do...

System.err.println(e);
e.printStackTrace();
