Hello postgresql team, I'am trying to connect to the posgresql database through JDBC and it doesn't function. 1. I have made the postgresql.jar through the command "make jdbc2" -as it is described in /src/interfaces/jdbc/ source- and it is copied to my CLASSPATH 2. I have an access to the database through "psql" (the name of the database is "test"). 3.with this piece of code I'am trying to connect the data base: Class.forName("org.postgresql.Driver"); // load database interface // connect to the database String url = "jdbc:postgresql://gemini:6666/test"; conn = DriverManager.getConnection(url); /*gemini is the host where the postgresql had been started*/ /*I entered the the absolute location of gemini and it doesn't functions too.*/ but during the running of my java code I get these Errors: java.lang.NullPointerException java.lang.NullPointerException at org.postgresql.util.PSQLException.translate(PSQLException.java, Compiled Code) at org.postgresql.util.PSQLException.<init>(PSQLException.java, Compiled Code) at org.postgresql.Driver.connect(Driver.java, Compiled Code) at java.sql.DriverManager.getConnection(DriverManager.java, Compiled Code) at java.sql.DriverManager.getConnection(DriverManager.java, Compiled Code) at TestDBConnection.<init>(TestDBConnection.java, Compiled Code) at TestDBConnection.main(TestDBConnection.java, Compiled Code) The port (6666)was defined during the installation. Can you tell me please where could be the probleme Thank you for your help in advance Elie Atallah
