Thread: Postgresql java and blobs

Bonjour !

Am part of the c-jdbc clustered databases project:
http://c-jdbc.objectweb.org/index.html

and would like to build a driver on top of the pg7*.jar driver for the
postgresql database for clustering.

The idea is to feed in a blob in the database and then retrieve it and
check its validity ( no escape characters for instance )

At the moment I am using the BIT VARYING type for storing the blob as
other types return to me an
"invalid type exception should be [TYPE] but expression is of type bit
The driver though fails with (No class found for varbit)
No class found for varbit

it seems the cast made for blob is not properly made or I am mistaking ?

The code works fine for other databases, but I am stuck in here.

Help ?
