I am trying to connect to PostgreSQL database on my local system.

The code is:

Class.forName("org.postgresql.Driver");
String url = "jdbc:postgresql://localhost:5432/postgres?user=postgres&password=major";
Connection conn = DriverManager.getConnection(url);

Running the code I get:

org.postgresql.util.PSQLException: Protocol error. Session setup failed.

Using postgresql-8.4-701.jdbc3 on PostgreSql 8.4






Try adding some debug info (will help us see what is going on) - e.g:



 Class.forName("org.postgresql.Driver");
 String url = "jdbc:postgresql://localhost:5432/postgres?user=postgres&password=major";

 Properties props = new Properties();
 props.setProperty("loglevel","2");

 Connection conn = DriverManager.getConnection(url, props);



regards

Mark
