Web Application WAR file -> Web Services tabbed pane
In the Web Services tabbed pane, you can define a web service for your Web application.
To define a Web Service, do the following:
To edit a web service definition, select the row containing the reference and click Edit.
To delete a definition, select the row containing the reference and click Delete. A confirmation dialog will ask you if you really want to delete the web service definition.
To provide a URL for the WSDL publish location, select a defined service from 
the Web Services pane and enter a URL in the WSDL Publish Location field. The 
WSDL Publish Location is optionally used to specify where the final WSDL 
and any dependent files should be stored.  This location resides on the file 
system from which deployment is initiated.
