Wow! I just installed the jTDS JDBC driver for Microsoft SQL Server, and it does
*not*
produce the NULL parameter problem that I encountered using Microsoft's SQL Server
JDBC
in the
implementation of sql:param where it treats null as a string
argument rather than as an SQL null argument.

It certainly could be a driver issue, but you've gotta pass null instead of
null to find out ;-). The Standard taglib uses the following to set SQL
parameters:
PreparedStatement.setObject(int parameterIndex, Object x)
It should be pretty easy to write a simple JDBC test to see how your driver
