How to throw exception w/RMI from Server->Client w/o "nested exception..." mentioned

[nicoeschpiko]

I have a Server throwing a custom exception defined:

package class.project;

import java.rmi.RemoteException;

public class SecurityException extends RemoteException {
	/**
	 * Serializable class SecurityException requires declaring a static final serialVersionUID field of type long
	 */
	private static final long serialVersionUID = 1L;

	/**
	 * Constructor used to pass msg String argument up to Exception class constructor.
	 *
	 * @param msg  String argument 'msg' passed up to Exception class constructor
	*/
	public SecurityException(String msg) {
		super(msg);
	}
}

to the Client via RMI, where the Client attempts to display the SecurityException:

	public static void performTestOne(ATM atm) {       
		try {
			atm.getBalance(getAccountInfo(0000001, 5555));
		} catch (Exception e) {
			System.out.println("Failed as expected: "+e);
		}
	}

And I am wondering how to only display the SecurityException details provided by the Server:

if ( !this.security.authenticateTransaction(account_info, account) ) {
				throw new SecurityException( "Unable to authenticate transaction.  Invalid username/password combination." );
			}

Unfortunately I am getting the following output:

Failed as expected: java.rmi.ServerException: RemoteException occurred in server thread; nested e
xception is:
class.project.SecurityException: Unable to authenticate transaction. Invalid username
/password combination.

What I need to see is:

Failed as expected: class.project.SecurityException: Unable to authenticate transaction. Invalid username
/password combination.

Instead of

System.out.println("Failed as expected: "+e);

try...

System.out.println("Failed as expected: "+e.getCause());

When a remote object throws an exception, it gets bundled into a java.rmi.ServerException as the 'detail' field. Also, you'll have to change your catch statement to specifically catch a ServerException instead of the more generic Exception for this to work.
