I think you may be able to get some information you need about function by the following
system catalogs query: 
select s.schemaname, a.alias, a.javaclassname from sys.sysschemas s, sys.sysaliases a where
a.schemaid = s.schemaid and a.aliastype = 'F' or you can get function information by invoking

Here is some documentation about built-in function:
Java DB supports upper, lower, concat, substring, like, length, trim; see SQL-99 and SQL-2003
features including data types are mapped to Derby, section E021.

Hope this help!
