[jdom-interest] SAXBuilder in JSP session scope object

I have a SESSION scope Java Bean in a JSP page using a
SAXBuilder. Assume we use the JAXP default SAXParser
crimson parser.  
My question is: Is there a big difference in memory
usage between the following two approaches:
1. Each session object has its own SAXBuilder. 
2. create an external APPLICATION scope synchronized
pool to store a group of SAXBuilders, and get/return
instances from pool each time the page get executed.

In short, is SAXParser instances expensive?

 Also, do I need to mark the SAXBuilder as transient
in the JavaBean?

Thanks very much,
