Java and XML

[sandeep dhingra]

I have an application in which data is stored in some Java object, I want this to be written to a file and this file should be a XML file, because if changes are made later to the structure of the object(a new version is developed)it is easy to convert the old file with the same structure as the new one.
Anybody here can help me in this.

You can serialize those objects to XML and store in a file.

Yes ,you can use XMLserializer to serialize objects to XML file.

here is a sample,maybe help

[Ulf Dittmer]

If the class follows JavaBeans semantics, then it's very easy to serialize it using the java.beans.XMLEncoder and XMLDecoder classes.

JAXB - Java API for XML Binding, would do the job required for you.

Perhaps, this tutorial from Sun about JAXB would help you with a quick example.
