JDBC parameter binding not working for PL/PGSQL block JDBC3 Version 9.0-801

Database postgresql90-server-9.0.2-1PGDG.rhel4
CentOS 4.7
JDBC3 Version 9.0-901.

I'm working on a project converting a number of applications from Oracle to
Postgres and am running into a problem with the Postgres JDBC driver or the
database.

When trying to setString(1,?) where the ? is in a pl/pgsql block I get an
error.
I included the error and portion of the code.
