    Default JDBC Problem - com.mysql.jdbc.Driver

    I am trying to connect to my MySQL DB with JDBC but I am having a problem with my servlet. I have my Data Access Object class which is able to establish a connection with the db. In my servlet init() function, I try to establish a connection using my DAO class but I keep getting the error message "com.mysql.jdbc.Driver". I do not understand what is happening as this worked fine in the DAO class.


    Servlet.java
    private Dao dao = new Dao();
     
    public void init() {
     	dao.connectToDB();   	
    }

    Dao.java
    public  void connectToDB() {
        try {
            Class.forName ("com.mysql.jdbc.Driver").newInstance ();
            conn = DriverManager.getConnection (databaseURL, userName, password);
            System.out.println ("Database connection established");           
        } catch (Exception e) {
            System.err.println ("Cannot connect to database server");
            System.err.println ("Error message: " + e.getMessage());
        }  finally  {
            if (conn != null) {
                try {
                    conn.close ();
                    System.out.println ("Database connection terminated");
                } catch (Exception e) { }
            }
        }
    }

    Default Re: JDBC Problem - com.mysql.jdbc.Driver

    What is the exception message?
    Paste here so that we could look over it. Also give the details about your variables, i mean where are they declared and what are there datatypes and scope too.
