This simply means that stmt is NULL at this point, i.e. the previous call
to Connection.createStatement() failed. We can't help you unless you post
the whole source file.

You should not do this as the classes in the propsitory are loaded using a
special classloader which detects changes files. You should rather put
freetds_jdbc.jar into wrapper.classpath in /etc/jserv/jserv.properties and
make sure that the system classes (classes.zip for JDK 1.1) are also included
in this classpath.

BTW: This is the wrong mailinglist for this question, please use debian-user
next time (it's also off topic on debian-java).
