To avoid NotSerializableException make sure:

1. your class implements Serializable
2. all non primitive members implement Serializable (or are transient instead)
3. if your class is an inner class it's either static or the outer class implements Serializable

Besides that you also need to define serialVersionUID for every Serializable class. Check all 3 cases above plus:

1. all Serializable superclasses
2. if your class is an anonymous class, define it there too

Note: your code may run without serialVersionUID sometimes but read the last paragraph in Serializable's javadoc to understand why it will

be a problem depending on the environment.

There's a VM option to add details to the exception. It will show the root and nested classes failing to serialize and help you figure out what you're missing:
