jdbc with a UDF

[Dave G]

I'm getting what appears to be a java reference back from values I return
from a UDF.  The values appear find using php, and in the mysql client. 
The result looks something like:

B@1e19999

The result should be a string (some representing floats, others as integers).

Any help will be appreciated.  I searched on google and only found where
another person had the same problem, but no solution.
