Actually, your question should be the other way around. The parsers I use (besides Crimson) are Xerces (apache) and XML4J (ibm). I know these support JAXP1.1.
For more info I refer you to the Web Developers Virtual Library, which maintains a list of available XML parsers at: http://wdvl.com/Software/XML/parsers.html
Go from there to see if they support JAXP.
Good luck.
Hello,
You can use Xerces from Apache (see: http://xml.apache.org/)
They also have a comparison between Crimson and Xerces:

http://xml.apache.org/~andyc/xerces2/xerces.html
Hope this helps,
Kind regards,
Hans.
