A first-steps intro to Java Web Services and their role with iPhone applications. We code an iPhone app and connect it to Java Web Services and discuss how they are already playing together in today's commercial iPhone app market.

1. iPhone Development
and
Java Web Services 101
a Practical Tour And Demo

2. Thanks for calling to
upgrade your DSL

3. What operating
system do you use?

4. Mac OS

5. Is that before or
after Vista?

6. ...umm

7. I’d say, about 10
years after

8. Ok, thanks for
confirming that sir.

10. Why
the iPhone?

13. Overtaken Blackberry
in sales

15. even Overtaken
Moto RAZR in sales

16. 2,000,000 apps sold
as of Oct 21, 2008

18. Why
Web Services?

19. Web Service Languages
★Java ★Perl
★.NET ★Python
★Ruby ★C
★PHP

20. Independent of platform
Consumed by any type of app
•Desktop
•RIA
•Headless

21. Nearly EVERY app is becoming network aware

22. Java Web
SOAP/REST/HTTP iPhone
Services Objective C

23. Java Web Services

24. JWS Tools
•IntelliJ •NetBeans
•Native support •SOA Plugin
•Eclipse •Maven
•SOA Plugin •Axis Archetype

25. RESTful
vs
SOAPful

26. SOAP

27. REST
http://localhost/drawing/

28. Java Web Service Servers
• JAX-WS
• Axis
• JAX-RS
• JSR311, Glassfish component “Jersey”
• Java 6
• Local HTTP server
• APT, or BARE needed for SOAP

29. iPhone Objective C

30. iPhone Dev Process
Free Membership
• SDK
• Simulator
Paid Membership
• Provisioning
• Deploy to Dev Device
• Digitally Sign Apps
• App Store

31. iPhone Dev Tools
• Dashcode = JavaScript
•Interface Builder, NIBs
•XCode

32. Objective C
• No Garbage Collector
• GC only on Mac OSX Desktop
• Manual Release of Memory
•C with Objects

35. Objective C REST
• Minimal Parsing
• Text Based (Primarily)
•Simple HTTP request
• Changing of request types
• @GET, @POST, @PUT

36. iPhone REST Demo

37. Objective C XML
• SOAP
• Heavy Wrappers, Headers, No Libs
• Help with XML Parsing
• NSXMLParser API

38. iPhone
SOAP Demo

39. Other
dev Tools

40. •SOAPui
•Apache TCPMon
•TCPDump
•Firefox Poster
•Netbeans WS/REST Tester

41. What’s next
• Java
• Native? Sun has promised
• Flash
• Native? Adobe has pledged
• JavaFX
• Does anyone care
• Let’s get it on the desktop first (Dec 2)

42. Takeaways
• iPhone Dev is Challenging
• Application process painful
• Manual memory management
• Cryptic APIs
• Java Web Services are Easy
• Minimal Gotchas
• Rest vs SOAP decisions
