Well, I've had my religious arguments here before on this subject but I'll 
offer them up again for a "Cinquo De Mayo" barbecue :).  Coming from a 
package development background, I tend to agree with the original poster 
regarding "platform independent" development.  On the other hand, having a 
performance background as well ("choose the ShowCase ODBC, it's faster than 
that MicroSoft junk" -- me, circa 1994) I have a problem using "generic" 
constructs for I/O.

My suggestion was, if you are planning to support multiple servers, create a 
generic JAVA version that will run anywhere.  After the base application has 
been tested and verified, start developing server-side programs specific to 
the platform to be supported.  For example, use a control record that tells 
the application that it is talking to an AS/400, so use the toolbox stuff.  
Sounded good to me at the time, but the "purists" tended to disagree.  
Personally, I don't _WANT_ my stuff to run like it's on Windoze ;-)...
