COPY problem in JDBC driver

Hi,

I apologise in advance if this has been solved but I haven't found any reference to it online.

I am using the COPY implementation in the latest (postgresql-8.4-701.jdbc4) driver with Java VM 1.6.0 (Mac OSX)

My code is the following (just trying to insert a string from a file into a single column):

public static void main(String[] args) {
try {
Class.forName("org.postgresql.Driver");
Connection connection = DriverManager.getConnection("jdbc:postgresql://127.0.0.1:5432/xseq_zip","postgres", "postgres");
PreparedStatement statement = connection.prepareStatement("DELETE FROM jdbctest");
statement.execute();
System.out.println("Erased Db");
System.out.println(connection.toString());

PGConnection pConn = (PGConnection)connection;
CopyManager copyManager = pConn.getCopyAPI();
String columns = "(name)";
copyManager.copyIn("COPY jdbctest " + columns + " FROM '" + "/Users/foobar/Documents/bulk.txt" + '");

}

catch (Exception ex){
ex.printStackTrace();
}
}

The code inserts the value from the file into the db but throws the following exception:

org.postgresql.util.PSQLException: Received CommandComplete 'COPY 1' without an active copy operation
at org.postgresql.core.v3.QueryExecutorImpl.processCopyResults(QueryExecutorImpl.java:918)
at org.postgresql.core.v3.QueryExecutorImpl.startCopy(QueryExecutorImpl.java:713)
at org.postgresql.copy.CopyManager.copyIn(CopyManager.java:52)
at tests.JDBCTest.main(JDBCTest.java:33)

Has anyone noticed this before? Am I doing something wrong?

Thanks

Michael
