No, that's a very common misconception, and I don't know why. 
SAXParser/SAXParserFactory were added to JAXP 1.0 because it only 
supported SAX 1, which did not have any equivalent of 
XMLReader/XMLReaderFactory. They are absolutely unnecessary with 
SAX2, and they do not work as well as XMLReader/XMLReaderFactory. The 
current version of JAXP, which supports SAX2, does include 
XMLReader/XMLReaderFactory. In 2003 no new code should be written 
with SAXParser/SAXParserFactory in J2ME or J2SE.

J2ME by its nature is riddled with incompatibilities. It subsets many 
APIs, not just SAX. THe question here is which classes should be 
picked out of JAXP for the J2ME subset. Eliminating 
SAXParser/SAXParserFactory and adding XMLReader/XMLReaderFactory 
would be no more incompatible than the reverse.
