Re: [xml-dev] Problem using JAXB (from Sun)

[Mukul Gandhi <mukul_gandhi@yahoo.com>]

Instead of implementing java.io.Serializable, I had to
implement XMLSerializable by the CatalogueEntry class
(or for any class for that matter).

Now I am not getting error, but the XML output coming
is blank i.e just this,

<?xml version="1.0" encoding="UTF-8"
standalone="yes"?>

Can someone please tell what could be the problem?

Regards,
Mukul
