For one thing, this code won't compile, since www.yahoo.com needs to be 
quoted.  It also won't look for mail servers, since you don't specify a 
type to the Lookup constructor.

There's no reason that this should throw a NumberFormatException.  Without 
seeing the actual exception and code, it's impossible to know why.

Neither setting a Resolver or setting system properties should be
necessary if your system is configured correctly.

You don't provide enough information for the question to be answered.  If 
you provide more, I'll look into it.
