The amount of information that you have provided us is
not sufficient (at least for me, because I have not
had a chance to encounter such an error message during
my programming carrier).

Please write us your jsp  code snippet that deals with
the db, and the sql  script for your table so we may
find the cause of the error.

I think the size of one of your table's fields is
less than the size of data to be stored,
check them , you may need to increase the size
of one of your varchar fields.

probabely the field length is smaller than the
value you pass to database,
you can increase the size of field
but if this solution does work ,describe your
problem more.
