GetConnection(String URL) vs. (String URL, String user, String password)

Question

Hi,
would have a question referring to the documention at http://docs.oracle.com/cd/E11882_01/appdev.112/e13995/oracle/jdbc/OracleDriver.html where the forms of getConnection are described.
I would like to convert from using a signature that takes the URL, user name, and password as separate parameters to using a signature that takes the URL, user name, and password all as part of a URL parameter.
While I was able to successfully connect to my database using the form getConnection(String URL, String, user, String password); I am not able to achieve the same when using getConnection(String URL).
Here are the code snippets, maybe someone can point out the reason why the second approach is not working?
approach 1 - working fine
String driver = "oracle.jdbc.driver.OracleDriver";
try {
          Class.forName(driver);
          } catch(java.lang.ClassNotFoundException e) {
          String connectionURL = "jdbc:oracle:thin:@localhost:1521:PMT";
          String pgUser = "\"James.Smith@000\"";
          String pgPwd = "\"js\"";
     try {
               Connection conn = DriverManager.getConnection(connectionURL, pgUser, pgPwd);
approach 2 - error: java.sql.SQLException: The Network Adapter could not establish the connection
String driver = "oracle.jdbc.driver.OracleDriver";
try {
          Class.forName(driver);
          } catch(java.lang.ClassNotFoundException e) {
String connectionURL = "jdbc:oracle:thin:\"James.Smith@000\"/\"js\"@localhost:1521:PMT";
     try {
               Connection conn = DriverManager.getConnection(connectionURL);
Thanks a lot in advance
Kind regards
Thomas

Answer 1

Let me get this clear.
You want a login dialog.
Some program calls the dialog and waits untile user respond
once the user press ok or cancel it reutrn the users input to the caller.
You can do this directly using JFrame
but you can do it wil JDialog if you use it as aModal dialog.
it will look like this
class LogInDialog  extends JDialog implements ActionListener{
   String value;
   public LogInDialog(){
      setModel(true);
    // This is what you invoke
    public String loadDialog(){
        setVisible(true);
        return value;
    public void actionListener(..... e){
        if (e.getSource() == bCancel)
           value = null;
        else if (e.getSource() == bOk)
           value = //generate the string
        dispose();
}
