The document discusses the Rich AJAX Platform (RAP), which allows for modular business applications with significant code reuse and cross-platform capabilities. It highlights the evolution of RAP, its architecture, and the advantages of using Java for development, along with features like reusable components and custom theming options. The RAP enables developers to create applications that can run on both desktop and mobile environments with minimal effort.

Web & RCP

8. Rich vs Web
o Rich client: Also known as a desktop application, native application,
thick client, or fat client
o Web client: Also known as a web application, Internet/Intranet
application, web user interface, and thin client

o Rich web client: Also known as a rich Internet application, Ajax client,
Web 2.0 client, and fat thin client.
• Java Script - modify static content
• Ajax - asynchronous requests
• Dynamic JavaScript and HTML
Focus on one development language and environment.

14. RAP Vision
No need for WEB in…WEB

15. The RAP Vision

16. The RAP Vision
16

17. • Reusable components
• Consistent look & feel
• Save money
• Custom components
17

18. The RAP Vision
18

19. • Use only Java
• Tooling – Junit
• Full IDE support
• Much like SWT
No need for HTML ! ! !

21. The RAP Vision
21

22. • RCP powerful framework
• Plugins, plugins, plugins…
• Separates RCP into server and client
22

23. The RAP Vision
23

24. • Third party source code
• Easy to upgrade
• Decouple applications development
Did you know ? As long as a plug-in is not currently in use, it can
even be exchanged while an application is running
24

25. The RAP Vision
25

26. • No need to rewrite for WEB
• Little effort of developer side
• Use application vice versa
26

27. The RAP Vision
27

28. • SWT part of the Eclipse
• Reimplements SWT
• Advantage compared to GWT or WICKET

29. Architecture

31. Architecture

32. QOOXDOO
// Create a button
var button1 = new qx.ui.form.Button("First Button", "icon/22/apps/internet-web-
browser.png");
// Document is the application root
var doc = this.getRoot();
// Add button to document at fixed coordinates
doc.add(button1,
{
left : 100,
top : 50
});
// Add an event listener
button1.addListener("execute", function(e) {
alert("Hello World!");
});
32

33. Architecture
Did you know? The word equinox means equal day and night 33

34. “ Always code as if the person who will
maintain your code is a maniac
serial killer that knows where you live.”
“..Visual C++, Tip of the day…”

35. What you know so far
JFace Workbench
SWT

36. Example
RCP to RAP in 5 minutes

37. RCP Mail

38. Demo
38

39. API Differences
RCP
aboutAction = AboutAction.ABOUT.create(window);
register(aboutAction);
RAP
aboutAction = new AboutAction(window);
register(aboutAction);
RAP + RCP
aboutAction = AboutActionHelper.create(window);
register(aboutAction);
39

40. Demo continued
40

41. Different app , same code

42. 42

43. Cool stuff
Branding, Extension, Theming..

44. Testing
Supports standard JUnit testing
public class MyTest extends TestCase {
...//
{
Visible interface tests
public class MyTest extends RAPTestCase {
...//
{
44

45. Branding
Define visual aspects
Special branding for group
Theming - CSS

46. plugin.xml
Themes
Register the New Theme
<extension
id="firstTheme"
point="org.eclipse.rap.ui.themes">
<theme
file="themes/myTheme/new.css"
id="RCP.theme1"
name="theme1">
</theme>
</extension>
Activate the Theme
<extension
point="org.eclipse.rap.ui.branding">
<branding
defaultEntrypointId="RCP.entrypoint1"
id="RCP.branding1"
servletName="RCP.branding1"
themeId="RCP.theme1">
</branding>
</extension>

47. Result
47

48. Even more…
Run in cluster
RAP mobile
Easy deployment Libra
48

49. Summary
Rapid development
Stay away from writing JavaScript, HTML and CSS
Single Codebase - RAP can be compiled into an
RCP application and Native mobile as well.
