Images on Reports using LongBlob field types

Development
1

Hi All,

I'm trying to place a signature image onto a report generated from the CE
version of Jaspersofts iReport.

Following the directions in the product manual I've placed an image holder
into a detail section of the report, given it the class java.awt.Image and
used the value field from the appropriate signature table as the source.
However the report fails to compile returning the following error:

Error filling print... Unknown image source class [B
Setting up the file resolver...
net.sf.jasperreports.engine.JRException: Unknown image source class [B

Appreciate this involves another product but has anybody any ideas as to
the way forward?

Many Thanks
