Appendix B
Distributed Objects
Jim Farley, Java Distributed Computing, O’Reilly, 1998, ISBN: 1-56592-206-9. Provides a Java-centric view of distributed computing technologies.
Ron Hipschman, How SETI@home Works, http://setiathome.ssl.berkeley.edu/ about_seti/about_seti_at_home_1.html.
Interesting background on the SETI@home project, which uses distributed computing to analyze data from space.
Sassafras Software, General KeyServer Questions, http://www.sassafras.com/faq/ general.html
Information about KeyServer, an application that uses distributed computing to control software licenses.
CORBA
The Object Management Group’s CORBA site at http://www.corba.org
CORBA is a “product” of the Object Management Group (OMG). This Web site contains basic background information and links to the actual standards involved.
Michi Henning and Steve Vinoski, Advanced CORBA Programming with C++, Addison Wesley, 1999, ISBN: 0-201-379270-9.
There are a lot more books out there on CORBA with Java than with C++. This book focuses on C++, and, despite the title, is accessible to a CORBA beginner.
XML and SOAP
Ethan Cerami, Web Services Essentials, O’Reilly, 2002, ISBN: 0-596-00224-6.
This book explains the emerging concept of Web services and the use of SOAP for distributed computing. Examples are provided in Java.
Erik T. Ray, Learning XML (Second Edition), O’Reilly, 2003, ISBN: 0-596-00420-6.
The de-facto XML reference. Includes discussions of associated technologies like XML schema, XPath, and XHTML.
James Snell, Doug Tidwell, Pavel Kulchenko, Programming Web Services with SOAP, O’Reilly, 2001, ISBN: 0-596-00095-2.
This book discusses SOAP and related technologies, such as UDDI and WSDL. Examples are provided in Java, Perl, C#, and Visual Basic.
Eric van der Vlist, XML Schema, O’Reilly, 2002, ISBN: 0-596-00252-1.
This book tackles the difficult topic of XML Schema and discusses the nuances of the language.
Altova Software xmlspy, www.xmlspy.com.
