Isn't harmonious Type 4 Driver and Graphic Column

[jhs4232]

I programmed java using type 4 driver.
I had queried the Graphic column.
(Staffg of the IBM sample DB)

When I used to type 2 and type 3 , I succeed to the results. But, When I used to type 4, It occurred the error.


OS : Windows XP
DB2 V8.1.5

Error :
Connect Error
