And be very upset if the result is not 4! But yes, it really is possible to have a complete
SOAP client in two lines of Java, given the fact that the arguments are primitives and given
all the other work that
wsimport
and the toolkit have done for us:
// no imports!
/** Two-line client for Calc Service, complete code. */

class
TinyClientMain

$ java -cp target/classes jaxwsclient.TinyClientMain

The actual client in the
jaxwsclient
package provides an interactive calculator that lets you
input lines like
2 + 2
and get the answer:
$ java -cp target/classes jaxwsclient.ClientMain
Interactive calculator. Put spaces around operators.
>> 2 + 2
2 + 2 = 4
>> 22 / 7
22 / 7 = 3
>> ^D

Brilliant, eh? Incidentally, there is both a unit test in the service package and an integration
test (which just uses the static
Endpoint.publish()
to start and stop the service) in the cli-
ent package.
To recap, we did the following:
1. Created the service (but usually that will already be done for you).
2. Got the WSDL from the service with endpoint via “the
?wsdl
trick”.
3. Ran the WSDL through
wsimport
to generate the client artifacts.
