Hate to ask when I don't believe I have near enough information, but my 
knowledge o Java is so small that I don't even know where to begin debugging ...

Have a client running an application, that, when run on an older FreeBSD 4.x 
machine, with jdk from ports, ran great ...

Recently, upgraded them to FreeBSD 6.x, with Diablo, and from a 32bit server to 
a 64bit server, and now whenever they submit certain forms on the site, it 
generates the following error:

java.lang.NullPointerException
	java.lang.String.getBytes(String.java:811)
	org.dataisland.wrapper.servlet.HttpServletWrapper.streamDocument(HttpServletWrapper.java:346)
	org.dataisland.wrapper.servlet.HttpServletWrapper.serveDataIsland(HttpServletWrapper.java:316)
	org.dataisland.wrapper.servlet.HttpServletWrapper.service(HttpServletWrapper.java:277)
	javax.servlet.http.HttpServlet.service(HttpServlet.java:802)
	org.opencommerce.iface.servlet.filter.Secure.doFilter(Secure.java:64)

The site *appears* to work fine otherwise ... its an e-commerce site, and I can 
add products to my shopping cart, search the database, etc ... but, for 
instance, if I try to update my profile, or they try and update prices, the 
above happens ...

Can someone suggest what, if anything, I can do to debug this a bit more 
intelligently?

Thanks ..
