Re: jdk1.6.0_14 and OracleXE connection problem

Ouch, looks like I messed up big time without spotting my own mistake

Java Syntax (Toggle Plain Text)
import java.sql.*;
 
public class OracleConnect {
    public static void main(String[] args) throws SQLException {
        try {
            Class.forName("oracle.jdbc.OracleDriver");
            Connection conn = DriverManager.getConnection("jdbc:oracle:thin:@localhost:1521:XE", "username", "password");
            if (conn != null) {
                System.out.println("I am Connected to oracle database");
            }
            conn.close();
        }
        catch (Exception e) {
            System.out.println("ERROR : " + e);
            e.printStackTrace(System.out);
        }
    }
}
import java.sql.*;

public class OracleConnect {
    public static void main(String[] args) throws SQLException {
        try {
            Class.forName("oracle.jdbc.OracleDriver");
            Connection conn = DriverManager.getConnection("jdbc:oracle:thin:@localhost:1521:XE", "username", "password");
            if (conn != null) {
                System.out.println("I am Connected to oracle database");
            }
            conn.close();
        }
        catch (Exception e) {
            System.out.println("ERROR : " + e);
            e.printStackTrace(System.out);
        }
    }
}

This is no longer a problem with your classpath setting which you were initially facing. Since it's an IOException, there might have been a lot of things going wrong here like the database not properly set to listen to connections etc. It would be kinda difficult to come up with a solution for us; do a web search for the given exception "Io exception: Got minus one from a read call" and check out the suggestions given there.
