> In some cases it might be necessary to specify the method signature of the external method
used as a function or procedure in Derby (using CREATE FUNCTION or CREATE PROCEDURE).
> This possibility is not documented in the manuals, but there is an entry in the FAQ (http://db.apache.org/derby/faq.html#null_args):
> Either declare the function with RETURNS NULL ON NULL INPUT or define the Java method
signature in the external name clause. See the "Create function problem"  derby-user mail
list topic.
> The mail thread: http://mail-archives.apache.org/mod_mbox/db-derby-user/200602.mbox/%3c4404E53D.1050605@apache.org%3e
> The relevant sections in the manuals should be updated to describe the feature.
