[java-dev] find a non-serializable class/object

I'm wondering if there's any way of tracking down the specific object that's causing a NotSerializableException? I have a fairly complex object that I'm trying to write to disk, and I keep getting this exception. I've checked all of my class files, and they all implement Serializable. If I could at least find out which object is failing, maybe I could figure out what's wrong.

Any thoughts appreciated.

thanks,

J.
