The main problem that I wanted to solve was how to process large XML files in chunks while at the same time providing upstream/downstream systems with some data to process.
Of course I've been using JAXB technology for few years now; the main advantage of using JAXB is the quick time-to-market; if one possesses an XML schema, there are tools out there to auto-generate the corresponding Java domain model classes automatically (Eclipse Indigo, Maven jaxb plugins in various sauces, ant tasks, to name a few).
It also provides high-level HTML form manipulation functions.

The simplest way is to mark a given type with @Xml Root Element annotation.
The drawback with SAX is that it processes the whole document start to finish; this might not be necessarily what one wants for large XML documents.
, which enforces heuristic restrictions on the number of entity expansions.
Note that this flag alone does not prevent resolution of external references (system IDs or public IDs), so it is slightly misnamed.
