[Jay Richards]

im trying to retrieve an image from a ms sql database for display using servlet:
...
data = rs.getBinaryStream(imagenum);
....
but i get this error:
java.io.IOException: [Microsoft][SQLServer 2000 Driver for JDBC]Object

what seem's to be the error... but when i tried porting it to mysql database. it works. (just changed the driver and the connect url)
it seems like a microsoft driver error?
help pls?
thanks
