Nima Falaki commented on NUTCH-1859:
------------------------------------

One more thing, I noticed that when the end user forgets to include a number 
after the -port argument, then a very unfriendly null pointer exception occurs 
(This also occurs in NutchServer.java)

So what I did was include a message saying "Please include a port number when 
using the -port argument" and I just defaulted to the default port of 8080. 

I also included a message saying what port we are running the webapp on. This 
is all in the 4k patch, which I just uploaded. I also included the 
NutchUiServer in the log4j.properties. 

What do you think? I could remove this if you do not like adding these 
messages. Or I can include another message if you do not like my message.

> Right now the Nutch WebApp only runs on port 8080... which will undoubtedly 
> have people running into conflicts all over the place.
> We should do the same as with nutchserver and make this configurable.
