I assume that you are asking about era packaging because your web service also an EJB. If that is correct, all you really need to do is package the EJB class in a jar file and copy the jar file to server/xxx/deploy. Then you should be able to view the web service using http://localhost:8080/jbossws/services.
Also, see the documentation at http://jbws.dyndns.org/mediawiki/index.php?title=JBossWS
I have a POJO that I need to expose it as a web service but can't find steps to follow to create a Web Service from creation to deployment, what commands to run to create a service any special configuration file needed etc.
The documentation (I gave you the link earlier) contains everything you need to a POJO-based web service.
I also have a tutorial that includes creating a simple web service, but it is not free. I can give provide the URL, if you like.
