gcj/gdb problem -- can't find source file

I am trying to use gdb with gcj. I have read the faq and the help file
available (http://gcc.gnu.org/java/gdb.html) and tried to search the
mailing list but haven't succeeded.

gdb appears not to find the source file so that the user can't follow
in the source file where execution is happening or examine local
variables.

The session below illustrates the problem (I also tried compiling the
Java source with gcj directly).

I am using the following versions
   gcj (GCC) 3.2 20020903 (Red Hat Linux 8.0 3.2-7)
   GNU gdb Red Hat Linux (5.2.1-4)

(and used slightly older versions on a RH7 machine to get the same)

Any help gratefully appreciated,

Thanks

Scott
