In what scenarios do we prefer JAXP over JAXB? I'm currently exploring on JAXB to perform a task and as far as I read through JAXB, I understand that XML processing is straight forward without the need to use SAX or DOM. Given this advantage, what is the need for JAXP?

There are few things that come only with advantages, and no disadvantages :-)

Having JAXB create all those objects carries a performance overhead, plus the need to have all those classes in the first place. Also, SAX code is more stable in the face of changing document structure - if you use JAXB, then your classes need to match the document, or there'll be problems.
I agree. Here's the link: http://aspose.com/file-tools
