Strange problem with JDBC URL

Question

Hi All,
I don't know whether this is a known issue which has a workaround or I am doing something wrong. But this is the problem.
I have a nice GUI application which takes the JDBC URL, Driver, User name and password and then takes the input and tries to establish a connection with the Database. I was trying it on MySQL and I encountered a problem.
The general format of the JDBC URL for MySQL is "jdbc:mysql://<ip_address>:<port>/<db_name> and if I have MySQL running on 3306 and if I give the URL as:
"jdbc:mysql://localhost:9001" (where my HSQL is running), then, it never gets the connection and the application stays there forever (the call never returns after the DriverManager.getConnection() statement). And if I give the port as something else (say 9898) where nothing is running, then the getConnection() doesn't send me a SQLException.
What could be the problem?

Answer 1

Are you saying that you're connecting using the
MySQL driver to an HSQL database, and
that this results in a hang (rather than a timeout)?
Just to clarify that I've understood the problem.
If so, it should be fairly easy to get a simple test
scenario up and running independent from your "real"
application. Have you tried this, and could you post
the code if so?
Dave.Hi Dave,
Thank you very much trying,
Sorry if my English was poor. I am not trying to connect to HSQLDB using the MySQL Driver.
Actually, I am trying to connect to MySQL db using the MySQL driver, but the DriverManager.getConnection() method hangs when I...
1. Give a wrong URL e.g(jdbc:mysql://localhost:9001/")
2. Run my MySQL on default port (3306)
3. And If I have HSQL or any other program that is listening at port 9001.
The problem seems to be very strange. here's the code below, you can try out yourself...
import java.sql.DriverManager;
import java.sql.SQLException;
public class Demo {
     public static void main(String[] args) {
          try {
               Class.forName("com.mysql.jdbc.Driver");
               DriverManager.getConnection("jdbc:mysql://localhost:9001/", "user", "password"); // <-- The call hangs here
          } catch (SQLException e) {
               e.printStackTrace();
          } catch (ClassNotFoundException e) {
               e.printStackTrace();
}Remember to have your mysql*.jar file in your classpath while running. :)
Thank you....
