Question

I was trying to serialize an ArrayList which contains custom objects.

I’m serializing it in a Servlet (server side), and deserialize at the client side. (using ObjectOutputStream and ObjectInputStream)

It worked fine, when I work with ArrayList<String>.
But when I tried it with ArrayList<MyObject> I couldn’t get any results in the client side, this is the exception:

java.lang.ClassNotFoundException: web.MyObject

Of course I have done this:

public class MyObject implements Serializable { ... }

MyObject contains only String fields.

What have I done wrong?

Thanks,
Ray.

The Problem is that your client doesnt know your MyObject when Deserialization. So you have to make sure that this class in also on the classpath.

Edit: oh sry i just saw that Anton was faster
