    Default JDBC_Servlet: Data not found

    There is some problem when i check username and validate it against password from the database.After checking password from request.getParamter() and validating it against password column from the database it should say "You have been successfully login"... Perhaps I am getting my own else block message"Incorrect Password..." which means there is some problem with the password thing. Here is my servlet code
    response.setContentType("text/html");
            PrintWriter out= response.getWriter();
            String uname= request.getParameter("txtuname");
            String pass= request.getParameter("txtpass");
            Connection con =null;
            try {
                Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");
                con=DriverManager.getConnection("jdbc:odbc:SQL","sa","mith1234");
                String select="select Password from sign_up where U_Name=\'"+uname+"\'";
                Statement st= con.createStatement();
                ResultSet rs= st.executeQuery(select);
                if(rs.next())
                {
                    //out.println(pass);
                    //out.println(rs.getString(1));
                    if(rs.getString(1).equals(pass))
                    {
                        out.println("You have been successfully logged in"+uname);
                    }
                   else 
                    {
                        out.println("Incorrect Password");
                    }
                }
            }
            catch(Exception e)
            {
                out.println(e);
            }
     }
    When i say out.println(rs.getString(1)) it is returning me the data from the database.... Any kind of help appreciated!!!!

    Hello mithcool. Welcome to the Java Programming Forums.

    Does rs.getString(1).equals(pass) ever return the correct value when you print it out?
