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

Had a slight problem in the Java that I fixed but the error is still the same.

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:

/mnt/ae_files/users/brady/postgres> java WhatTheF

            props.setProperty("user", PG_USER);

            ParameterMetaData pmd = pStmt.getParameterMetaData();
            System.out.println("Bound Vars = " + pmd.getParameterCount());

            pStmt.executeUpdate();
            pStmt.close();

                + " INSERT INTO soo (zoo) values (?);\n"
                + " END $$;");
            pmd = pStmt.getParameterMetaData();
            System.out.println("Bound Vars = " + pmd.getParameterCount());
LINE 35 ->      pStmt.setString(1, "Barf");
            pStmt.executeUpdate();
            pStmt.close();
            pgConn.close();
        }
        catch (Exception e) {
            e.printStackTrace();
        }


I'm guessing that anonymous plpgsql blocks cannot take input parameters.
