PostgreSQL 7.3.1 multiple schema select query error: java.sql.SQLException: ERROR: parser: parse error at or near "." - Mailing list pgsql-sql

I am using postgresql 7.3.1 on windows 2000. I downloaded the lattest
postgres jdbc driver
for version 7.3.1, called pg73jdbc3.jar and using JBoss-3.04_Tomcat-4.0.6.

I created one database called 'testdb', and a scheme called 'sc_test', with
a table called 'tbl_company' under the sc_test scheme.
When i execute the following query from java code, i get the following
error:

java.sql.Statement stmt1 = conn.createStatement();
Resultset rs = stmt1.executeQuery("SELECT * FROM sc_test.tbl_company");
