An I/O error occured while sending to the backend.

I am developing using the new PostgreSQL 8.0.0 rc5 under Windoz XP
(sorry).

I am also using Eclipse with the MyEclipseWorkbench and ACCESSING A
DATABASE ON localhost. In the code I make a valid connection and
immediately set up a prepared statement and execute a query.

The code is:

pstmt = connection.prepareStatement(SQL_GET_SEQUENCE);
pstmt.setString(1, this.name);
rs = pstmt.executeQuery();

The query is:

private static final String SQL_GET_SEQUENCE =
"SELECT " +
"seed " +
"FROM " +
"stocks.sequencer " +
"WHERE " +
"name = ?";

or
SELECT seed FROM stocks.sequencer WHEREname = 'test_sequence'

I am using the pg80b1.308jdbc3.jar jdbc driver.

The above query works through pgAdmin III and the MyEclipse Database
Explorer.... But when I run the above java code I receive the infamous

Exception: java.io.IOException: Stream closed

Others have said this is a TCP/IP problem with a firewall, but it's
pretty apparent that since I'm accessing "localhost"
(jdbc:postgresql://localhost:5432/test_database) that It's not a
"firewall" problem UNLESS there's a problem with the Windoz XP
firewall.

Any ideas? Suggestions?
