Connection is closed. Operation is not permitted. ------HELP....

Hi friends,

I have an application built on top of postgres database. I
recently updated my JRE from 1.4 to 1.6, with out changing the code.

But my application is throwing following exception frequently.

org.postgresql.util.PSQLException: Connection is closed. Operation is
not permitted.

at
org.postgresql.jdbc1.AbstractJdbc1ResultSet.next(AbstractJdbc1ResultSet.
java:138)

I am using "PostgreSQL 7.4.1" database server and "pg74.1jdbc3.jar"
driver. Can any one please help in this issue? It is affecting whole
system.

Do I need to upgrade my Driver also? If yes what is the correct driver
for JDK 1.6 with PostgreSQL7.4.1 server?

Thanks,

Darwin
