Perl
Python
C++
Java
Ruby
NET
PHP .

18. Independent of Platform

19. network aware
Nearly EVERY app is becoming

20. iPhone
SOAP/REST/HTTP
Java Web

Services

21. Web Services
Java

22. JWS Tools
IntelliJ NetBeans
Native WS SOA Plugin
support
Eclipse Maven
SOA Plugin Axis Archetype
Jersey Archetype

23. RESTful
vs
SOAPful

24. SOAP

26. REST
http://localhost/drawing/

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

28. Java REST Demo

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
• But we can use autorelease pools
•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

38. Memory Leaks

40. Provisioning Annoyances

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

43. other ways to load
your App

47. Trench Coat App Store
SSH
Terminal
Multilanguage Dictionaries
Hacking tools
1000s of other free seedy apps

48. Other
dev Tools

49. SOAPui
Apache TCPMon
TCPDump
Firefox Poster
Netbeans WS/REST Tester
CURL

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