java.lang.reflect.InvocationTargetException

[Martin Woolley]

Hello


I've just installed MySQL 4.1.14 along with the JDBC driver version
3.1.10.


When I try to connect to the database using a very simple Java app, I
get the following stacktrace:


** BEGIN NESTED EXCEPTION **


java.net.SocketException
MESSAGE: java.lang.reflect.InvocationTargetException


STACKTRACE:


java.net.SocketException: java.lang.reflect.InvocationTargetException

** END NESTED EXCEPTION **


I'm running on Windows XP btw. The simple Java app is as follows:


import java.io.FileInputStream;
import java.io.PrintStream;
import java.sql.DriverManager;
import java.util.Properties;


public class ConnectionTester
{


public static void main(String args[])
{
ConnectionTester connectiontester = new
ConnectionTester(args[0]);
}


public ConnectionTester(String s)
{
try
{
Properties properties = new Properties();
FileInputStream fileinputstream = new FileInputStream(s);
properties.load(fileinputstream);
java.sql.Connection connection = null;
String s1 = properties.getProperty("driver");
System.out.println("driverClassname:" + s1);
String s2 = properties.getProperty("url");
System.out.println("jdbcURL:" + s2);
String s3 = properties.getProperty("username");
System.out.println("username:" + s3);
String s4 = properties.getProperty("password");
Class.forName(s1);
connection = DriverManager.getConnection(s2, s3, s4);
System.out.println("Got connection....");
}
catch(Exception exception)
{
System.out.println(exception);
exception.printStackTrace();
}
}



}


Any ideas?

Thanks
