Note
To simplify this chapter's discussion of web services, I've avoided mention
of threads and thread synchronization, until now. According to the JAX-WS 2.2 spe-
cification (

jaxws-2.2-mrel3-evalu-oth-JSpec/
)clientproxyinstances(returnedfrom
Service
's
getPort()
methods)arenotguaranteed tobethreadsafe.Also,
Dis-
patch
instances(returnedfrom
Service
's
createDispatch()
methods)arenot
thread safe. In either case, you must use thread synchronization when these instances
will be accessed from multiple threads.
EXERCISES
The following exercises are designed to test your understanding of Java's web ser-
vices support:
1. Create a SOAP-based Library web service that recognizes two operations,
expressed via methods
void addBook(String isbn, String
title)
and
String getTitle(String isbn)
. Create a
LibraryClient
application that invokes
addBook()
followed by
getTitle()
to test this web service.
