Hi,
If the WSE did not exist when you first created the WSD, it won’t be visible.
Close the WSD editor and refresh (F5) the IS in the package navigator. You should then see the WSE on the port alias list.
It will only show the WSE that correspond to the WSD you are editing (HTTP, HTTPS, Consumer, Producer, etc). If your WSD was created from a WSDL which stated http as its location protocol, you cannot use an HTTPS WSE in the port alias, only an HTTP WSE.
