DB connection problem on JBoss/Linux

[sbutt]

Hi Folks,
I'm having problems in connecting to a mySql DB through JDBC on JBoss.

I'm using the following code.

try
 {
 String userName = "admin";
 String password = "m9ad3e";
 String url = "jdbc:mysql://hh-linux1/IntegraDB";
 Class.forName ("com.mysql.jdbc.Driver").newInstance ();
 conn = DriverManager.getConnection (url, userName, password);
 System.out.println ("Database connection established");


 }
 catch (Exception e)
 {
 e.printStackTrace();
 System.err.println ("Cannot connect to database server");
 }

It works fine on Windows/Tomcat.

But when i deploy the .war file on JBoss server running on linux it gives exception.

java.sql.SQLException: Access denied for user 'admin'@'HH-Linux1.usbeck.de' (using password: YES)

it is even trying to connect to some other server somehow admin'@'HH-Linux1.usbeck.de'?

Can someone pls help.
