I have Collection with objects which I want to persist to the file:

private List< TestPart > testParts;

Class TestPart is extending Abstract class and two interfaces. Is it possible to write that kind of collection to the file? I tried to use jaxb/kryo - without effect.

Class TestPart is not implementing Serializable interface and I can't change it.

I should also mention that class TestPart has a references to the other not serializable classes.

Any ideas how to save data like this?

Thanks in advance.

You could parse the collections into XML or json – jsedano Aug 01 '13 at 14:38

Mark the `List` as `transient` and modify the `writeObject` and `readObject` to perform a manual serialization of this field and its contents, similar for `readObject` method and the retrieval of the serialized content. – Luiggi Mendoza Aug 01 '13 at 14:38

you want to save an object that is not serializable , you can't . how can you expect from a collection of non-serializable to be serialize.? – Sachin Verma Aug 01 '13 at 14:39
You should check out [XStream](http://xstream.codehaus.org/). – Marko Topolnik Aug 01 '13 at 14:39
I should also mention that class TestPart has a references to the other not serializable classes. Post updated. – Jan Kusy Aug 01 '13 at 14:42
I checked XStream but I'm getting ConversionException – Jan Kusy Aug 02 '13 at 07:21
