Hi,
I am trying to connect postgresql database from a remote pc. Here is my code:
Class.forName("org.postgresql.Driver");
Connection conn = DriverManager.getConnection("jdbc:postgresql://machine.mylbl.gov:5432/mydatabase", "username", "passwd");
But I always get the following exception:
org.postgresql.util.PSQLException: The connection attempt failed.
Exception: java.io.EOFException
Stack Trace:
java.io.EOFException
