It's a non-trivial topic, meaning you have to write a parser yourself. You can get tools that will try to auto-generate a database out of XML, but often the logical structure is lost. For example, you might use database normalization for efficient storage of column data, but in the XML you want these tables denormalized so that a record contains all of its information.

In short, there's no magic solution since database don't necessarily have relationships easily discovered by a general purpose parser. Besides, writing a program that reads a database and outputs XML is good practice and this way you'll have 100% control over how the data is structured in the XML for easy customization.

One easy way is to use DBUnit through an ANT script. I'm not recommending it, just saying it is possible ( since DB Unit stores its info as XML)
 
It is sorta covered in the JavaRanch Style Guide.
