It depends on how you want to process the XML file and it depends on
what XML is being expected.
If the XML follows a particular structure you may be able to utilize
JAXB or utilize DOM and then operate on that using XPath expressions
to extract the bits of information.
However, you do say a "big XML file" which makes me think a streaming
solution is more efficient, using SAX or StAX might be OK but they are
low-level. A streaming XPath processor might be appropriate. Again it
depends on what information in the XML document you need to extract
out to populate records in the DB.
