One of them is used in inventoryCheck.jsp and things should be clear now.
So far, no SOAP. But we're getting there.
The application presented above is a good start, but now SkatesTown's partners are demanding the ability to have their purchasing applications directly inquire about order availability.
So let's install it as a web service.
The web service is here:

Fortunately it's easy to install axis, and we have done that already.
So adding a .jws file is basically nothing.
First, however, we take the service requestor perspective.
There are two files (one includes the other) that help make the call.

As far as Axis is concerned we've added it to our webapps.
(See Advanced Installation in the Axis installation instructions document.)
We have two more examples to go through.
What do they do?
Example 3 (ch3/ex3) simply also sends an e-mail message.
Example 4 does a little bit more.
