Mac OS X MySQL Connect throws Unexpected end of input stream

Question

With java version 1.4.2_05 I'm attempting to run an application which retrieves information from a MySQL database version 4.1 on Mac OS X Panther 10.3.6 The application operates without error on Windows and Linux using MySQL v4.0. Relevant Code appears below..
          private static final String DRIVER = "com.mysql.jdbc.Driver";
     private static final String URL = "jdbc:mysql://localhost:3306";
     boolean openConnection() throws SQLException, DatabaseException {
          try {
               if (con == null) {
                    StringBuffer sb = new StringBuffer(URL);
                    sb.append("/").append(getDatabase());
                    Class.forName(DRIVER);
                    /* Failure occurs here while calling getConnection on the
                    DriverManager class. */
                    con = DriverManager.getConnection(sb.toString(), getUser(), getPassword());
          } catch(SQLException sle) {
               sle.printStackTrace();
     } But on Mac X I'm seeing an exception thrown.
java.sql.SQLException: Communication link failure: java.io.IOException, underlying cause:
Unexpected end of input stream
** BEGIN NESTED EXCEPTION **
java.io.IOException
MESSAGE: Unexpected end of input stream
STACKTRACE:

        at java.sql.DriverManager.getConnection(DriverManager.java:171)I have checked to see that the proper permissions are established in the database. I've used the GRANT statement etc. It's unclear to me why I am having difficulty with the newer MySQL on Mac OS X. Any feedback is appreciated thanks.

Answer 1

I managed to solve this by having the MySQL server run as a service rather than attempting to start it via the application. So now the application can retrieve from the database without error.
