Peer I appreciate the reply
To become more specific to my implementation:
1.) I create the holder:
BigInteger bi = new BigInteger("0", 10);
Holder<BigInteger> status = new Holder<BigInteger>(bi);
2.) And then call the service:
port.existsUser(subsystemID, userNumber, status, errorMessage, userName);
After that, should I get the value of status like this:
System.out.println(status.value);
or is there a more appropriate way like:
System.out.println(status.getClass());
The holder concept is a bit misleading to newbies and there is not much sample code around.
