Pros and Cons
I've got a new way for
you to build web apps!
Raible D.
صفحه 8:
JSF
@ Pros:
@ Java EE Standard - lots of demand and jobs
@ Fast and easy to develop with initially
@ Lots of component libraries
@ Cons:
@ Tag soup for JSPs
@ Doesn't play well with REST or Security
@ No single source for implementation
صفحه 9:

Spring MVC
@ Lifecyle for overriding binding, validation, etc.
@ Integrates with many view options seamlessly:
JSP/JSTL, Tiles, Velocity, FreeMarker, Excel, PDF
@ Inversion of Control makes it easy to test
@ Cons:
@ Configuration intensive - lots of XML
@ Almost too flexible - no common parent
Controller
2 No built-in Ajax support
صفحه 10:
Stripes
@ Pros:
و No XML - Convention over Configuration
© Good documentation (easy to learn)
@ Enthusiastic community
@ Cons:
2 Small Community
@ Notas actively developed as other projects
@ Hard-coded URLs in ActionBeans
صفحه 11:
۳۳-۴ سس ٍ
Struts 2
@ Pros:
@ Simple architecture - easy to extend
@ Tag Library is easy to customize with
FreeMarker or Velocity
© Controller-based or page-based navigation
@ Cons:
@ Documentation is poorly organized
@ No feedback for missing properties or invalid
OGNL expressions
@ Googling results in Struts 1.x documentation
صفحه 12:
Tapestry
@ Pros:
@ Very productive once you learn it
@ Templates are HTML - great for designers
@ Lots of innovation between releases
@ Cons:
2 Documentation very conceptual, rather than
pragmatic
@ Steep learning curve
@ Long release cycles - major upgrades every year
صفحه 13:
۳۳-۴ سس ٍ
Wicket
@ Pros:
@ Great for Java developers, not web developers
@ Tight binding between pages and views
@ Active community - support from the creators
@ Cons:
@ HTML templates live next to Java code
@ Need to have a good grasp of OO
@ The Wicket Way - everything done in Java

Evaluation Criteria
Ajax Support: Is it built-in and easy to use? و
2 Bookmark-ability: Can users bookmark pages and
return to them easily?
@ Validation: How easy is it to use and does it support
client-side JavaScript) validation?
@ Testability: How easy is it to test Controllers out of
container?
صفحه 16:
دحع_عٍعچ حجچجچحچ چعچٍ
Evaluation Criteria, cont.
@ Post and Redirect: How does the framework handle
the duplicate post problem?
@ Internationalization: How is i18n supported and
how easy is it to get messages in Controllers?
@ Page Decoration: What sort of page decoration/
composition mechanisms does the framework
support?
@ Community and Support: Can you get questions
answered quickly (and respectfully)?
صفحه 17:
دحع_عٍعچ حجچجچحچ چعچٍ
Evaluation Criteria, cont.
@ Tools: وا there good tool (particularly IDE) support
for the framework?
@ Marketability of Skills: If you learn the framework,
will it help you get a job?
© Job Count: What is the demand for framework skills
on dice.com and indeed.com?
صفحه 18:
Ajax Support
@ Is Ajax support built-in and easy to use?
@ JSF: No Ajax support, use ICEfaces and Ajax4JSF
@ Stripes: No libraries, supports streaming results
@ Struts 2: Dojo built-in, plugins for GWT, JSON
@ Spring MVC: No libraries, use DWR & Spring
MVC Extras
@ Tapestry: Dojo built-in in 4.1
@ Wicket: Dojo and Script.aculo.us (Wicket Stuff)
صفحه 19:
Bookmarking and URLs
@ JSF does a POST for everything - URLs not even
considered
@ Stripes uses conventions, but you can override
@ Struts 2 has namespaces - makes it easy
@ Spring MVC allows full URL control
@ Tapestry still has somewhat ugly URLs
@ Wicket allows pages/URLs to be mounted
صفحه 20:
۳۳-۴ سس ٍ
Validation
@ JSF has ugly default messages, but easiest to
configure
@ Spring MVC allows you to use Commons Validator -
a mature solution
@ Struts 2 uses OGNL for powerful expressions -
client-side only works when specifying rules on
Actions
@ Tapestry has very robust validation - good messages
without need to customize
@ Stripes and Wicket do validation in Java - no client-
side
صفحه 21:
Testability
@ Spring and Struts 2 allow easy testing with mocks
(e.g. EasyMock, jMock, Spring Mocks)
@ Tapestry appears difficult to test because page
classes are abstract, Creator class simplifies
@ JSF page classes can be easily tested and actually
look a lot like Struts 2 actions
@ Wicket has WicketTester, a powerful solution
@ Stripes has Servlet AP] Mocks and MockRoundtrip
صفحه 22:
Post and Redirect
@ The duplicate-post problem: redirect after POST
@ Is there support for allowing success messages to
live through a redirect?
© Spring MVC allows you to add parameters to a
redirect
@ Stripes, Tapestry and Wicket all have "flash"
support
@ Struts 2 requires a custom solution
@ JSF requires a custom solution, i18n messages
difficult to get in page beans
صفحه 23:
29233331 27 ٠ر121 1 .سس
Internationalization
@ JSTL’s <fmt:message> tag makes it easy
@ No standard for getting i18n messages in controller
classes
@ Stripes, Spring MVC and JSF use a single
ResourceBundle per locale
@ Struts 2, Tapestry and Wicket advocate separate files
for each page/action
@ JSF requires resource bundle to be declared on each
page
@ Tapestry's <span key="key.name"> is awesome
صفحه 24:
رم
Page Decoration
@ Tiles Experience: used since it first came out
@ SiteMesh is much easier to setup and use
@ Tiles can be used in Struts 2, Spring and JSF
@ Requires configuration for each page
@ SiteMesh can be used with all frameworks
@ Requires very little maintenance after setup
@ SiteMesh not supported or recommended for use
with JSF, Tapestry or Wicket
صفحه 25:
Marketability of Skills
@ Struts 1 is still in high-demand and widely-used
@ Spring is getting more press, but mostly due to the
framework’s other features
@ JSF is becoming popular; awful with JSP
@ Struts 2 is gaining ground, but very scarce on job
boards
@ Tapestry has increased in popularity in last couple
years
@ Wicket and Stripes are virtually unknown

@ Project Future and Roadmap
8 Maintenance
@ Technical Features
صفحه 42:
Don’t believe the Hype
@ Don’t believe blogs and articles
@ Try it yourself
@ Believe developers, not evangelists
@ Believe developers that are experienced with the
framework and have used it in production
@ Beware of corporate interests - they can twist
marketing
@ Books are a good sign
صفحه 43:
Best Tool for the Job
@ Frameworks have sweet spots - is your
application one of them?
@ Pick 2-3 frameworks for your type of application...
@ ... and prototype!
@ If prototyping is painful, switch
@ Make sure you prototype more than one and doa
presentation comparing the pros and cons of each
صفحه 44:
After Choosing...
2 Document the reasons for your decision
@ Allow developers to challenge it
@ Allow your prototype to be written with other
frameworks
@ Don’t be afraid to try new frameworks
@ Don't be afraid to use old frameworks
@ Don’t be afraid to keep your existing framework

Conclusion
@ The future is bright because of all the competition
@ Developers should know more than one web
framework
© You should try a framework before dissing it
@ The plethora of web frameworks is a good thing!
@ Doing proper research can save time and money
@ Testing is the best path to future maintenance
