java webservices wsimport - parsing WSDL [ERROR] Server returned HTTP response code: 401 for URL: http://?wsdl needs authorization

i tried automatically creating a java webservices client for the following wsdl:
http://localhost:9001/wservice3/services/AdminWebService?wsdl

but running the following command in a terminal:
wsimport -keep -verbose http://localhost:9001/wservice3/services/AdminWebService?wsdl

gave me the following error:
parsing WSDL...

[ERROR] Server returned HTTP response code: 401 for URL: http://localhost:9001/wservice3/services/AdminWebService?wsdl,  "http://localhost:9001/wservice3/services/AdminWebService?wsdl" needs authorization, please provide authorization file with read access at /home/me/.metro/auth or use -Xauthfile to give the authorization file and on each line provide authorization information using this format : http[s]://user:password@host:port//<url-path>

so to make it work i had to first create an authfile composed of the wsdl URI plus my username and password:
echo http://myUsername:myPassword@localhost:9001/wservice3/services/AdminWebService?wsdl > wsxauthfile

then i ran the wsimport command again, this time with the flag -Xauthfile:
wsimport -keep -verbose -Xauthfile wsxauthfile http://localhost:9001/wservice3/services/AdminWebService?wsdl

and it generated the code for me in the current directory (i ran it from ~/Downloads/)

:)

here's the output i saw:
