Hi Michael,

Directory names (if they are relative file names rather than absolute 
paths) should resolve relative to the directory identified by the 
derby.system.home property, as resolved by the Derby engine code running 
in the servlet container. If that property is not set, it defaults to be 
the value of the JVM system property user.dir.

I am not aware of any special resolution of database names when Derby 
runs in a servlet container. The rules for resolving database names are 
described in the Derby Developer's Guide in the section titled 
"Conventions for specifying the database path" and in the Derby 
Reference Manual in the section describing the "derby.system.home" property.

Hope this helps,
-Rick
