THE PITCH

STRIPES IS A PRESENTATION FRAMEWORK FOR BUILDING WEB APPLICATIONS USING THE LATEST JAVA TECHNOLOGIES.

STRIPES GOALS

MAKE DEVELOPING WEB APPLICATIONS IN JAVA EASY...???

PROVIDE SIMPLE YET POWERFUL SOLUTIONS TO COMMON PROBLEMS

MAKE THE STRIPES RAMP UP TIME FOR A NEW DEVELOPER LESS THAN 30 MINUTES

MAKE IT REALLY EASY TO EXTEND STRIPES, WITHOUT MAKING YOU CONFIGURE EVERY LAST THING

THE BASE HIT

ZERO EXTERNAL CONFIGURATION PER PAGE/ACTION (ACTIONBEANS ARE AUTO-DISCOVERED, AND CONFIGURED USING ANNOTATIONS)

POWERFUL BINDING ENGINE THAT WILL BUILD COMPLEX OBJECT WEBS OUT OF THE REQUEST PARAMETERS

EASY TO USE (AND LOCALIZED) VALIDATION AND TYPE CONVERSION SYSTEM

LOCALIZATION SYSTEM THAT WORKS EVEN WHEN YOU USE DIRECT JSP ⇢ JSP LINKS

ABILITY TO RE-USE ACTIONBEANS AS VIEW HELPERS

EASY TO USE INDEXED PROPERTY SUPPORT

BUILT IN SUPPORT FOR MULTIPLE EVENTS PER FORM

TRANSPARENT FILE UPLOAD CAPABILITIES

SUPPORT FOR INCREMENTAL DEVELOPMENT (E.G. YOU CAN BUILD AND TEST YOUR JSP BEFORE EVEN THINKING ABOUT YOUR ACTIONBEAN)

MY INTRODUCTION

CONTEXT GOES A LONG WAY, SO ...

START WITH 10 YEAR OLD LEGACY CREDIT CARD APPLICATION PLATFORM

STRUTS 1.0.2, NO JSTL, WEBLOGIC 10.X

STRUTS 2?

SPRING MVC + WEBFLOW?

OTHERS?

LEGACY PLATFORM

10 YEARS OF CRUFT

LAZY ENGINEERS PUSHING BUSINESS LOGIC TO FRONT

SIGNIFICANT SCRIPTING

HEAVY JSP-BY-WAY-OF-PERL-LIKE ENGINEERING

THE CODE IS THE DOCUMENTATION (WEAK JAVADOC)

STRUTS 1.0.2

GOALS

REMOVE THE CRUFT, DECODE, INTERVIEW, DOCUMENT

PUT BUSINESS IN CONTROL AND REDUCE ERRORS

UPDATE PLATFORM FRONT TO BACK

ELIMINATE SCRIPTING AND ENFORCE MVC PATTERNS

SIMPLIFY DEVELOPMENT — FULL IDE DEV LIFECYCLE

SOLVE THE PROBLEM OF ON-BOARDING JUNIOR DEVELOPERS


HttpSession IS NOT A BAG OF HOLDINGMAKE CODE REVIEWS PART OF GOVERNANCECRUCIBLE+FISHEYE

WHY ARE WE PROCESSING THE VIEW THROUGH INCLUSION FILTERS AGAIN?

CAMPAIGNS HAVE EXPIRATION DATES. WHAT HAPPENS ON EXPIRATION? WHAT REGULATIONS ARE APPLICABLE ON EXPIRATION?

JAVADOC, DESIGN DOCUMENTS, BUSINESS PROCESSES

GOALS


PUT BUSINESS IN CONTROL

REDUCE ERRORS






BUSINESS KNOWS THE DURATION OF A CAMPAIGN AND THE EXPIRATION DATE

BUSINESS KNOWS HOW A CAMPAIGN EXPIRES, THE REGULATION, AND THE REPLACEMENT CAMPAIGN

BUSINESS ALREADY HAS BOTH THE REPOSITORY AND THE CHANGE CONTROL IN PRODUCTION

REMOVE DEVELOPMENT FROM CAMPAIGN DATA MANAGEMENT

GOALS



REDUCE ERRORS





REDUCE ERRORS

THE BUSINESS TOOLS ALREADY HAVE ALL THE CAMPAIGN DATA, STOP REKEYING IT

GOALS



REDUCE ERRORS






UI 10 YEARS OLD

SERVICES. SERVICES. SERVICES.

GRADUATE DATA

GOALS



REDUCE ERRORS






WHEN ONE SEES A JSP LIKE THIS:<%@ page import=”...”%><% Enumeration e = request.getParameters(); while(e.hasMoreElements()) { //put parameters on session } ... ... ... // 200 lines later %>

IT’S TIME TO READ THE JSP SPECIFICATION. PAYING CLOSE ATTENTION TO 3.3.3:<jsp-property-group> <url-pattern>*.jsp</url-pattern> <scripting-invalid>true</scripting-invalid></jsp-property-group>

GOALS



REDUCE ERRORS






EVER TRIED TO RUN WEBLOGIC 10.X LOCALLY? ON WIN XP? 4GB... NO, 3GB RAM?

EVER ASKED A JUNIOR DEVELOPER TO DO IT?

EVER ASKED A JUNIOR DEVELOPER SETUP MAVEN RUNNING, DEPLOY TO WEBLOGIC, DEBUG A JSP... OH, BUT NOT BEFORE INSTALLING ECLIPSE?

GOALS



REDUCE ERRORS






HOW DO WE GET TO “FULL IDE DEV CYCLE”?

CALL IT “PRESS THE GREEN BUTTON” OR “PRESS PLAY” DEVELOPMENT

GOALS



REDUCE ERRORS





EVALUATIONS

APPLY GOALS TO SOLUTIONS IN EVALUATION

NO ONE SELLS MVC FRAMEWORKS, ONLY SUPPORT

MEET THE CHALLENGERS:

STRUTS

SPRING MVC

STRIPES

STRUTS EVALUATION

LEGACY ON STRUTS 1.0.2

STRUTS 1.2MODERATE REENGINEERING; perform DEPRECATED

STRUTS 1.3SIGNIFICANT REENGINEERING, NIGH REWRITE; execute

STRUTS 2FULL REWRITE

PROS: DEVELOPER AVAILABILITY

CONS: VERSION CEILING WITHOUT FULL REWRITE

SPRING MVC EVALUATION

PROS

SUBJECTIVELY SPEAKING: BETTER THAN STRUTS 2

DEVELOPER AVAILABILITY

STACK INTEGRATION

CONS

SOME CONVENTION, MOSTLY CONFIGURATION

FULL REWRITE

COMMON PAIN POINTS

NO ESCAPING FULL REWRITE

FRAMEWORKS MAY ADD NEW TECHNOLOGIES TO LEARN

ENGINEER CENTRIC

CONFIGURATION VERSUS CONVENTION

STRIPES EVALUATION

PROS

LIGHTWEIGHT

ALL CONVENTION

FEATURE RICH AND LATENT FUNCTIONALITY

CONS

DEVELOPER AVAILABILITY

FULL REWRITE

LEGACY TO NEXT GEN

STRIPES VS. ET. AL... STRIPES PREVAILS. HOW? WHY?

THE STRIPES PROTOTYPE TEAM DELIVERED COMPLETE FEATURES TWO WEEKS BEFORE STRUTS AND SPRING

STRUTS AND SPRING TEAMS COULD NOT DEMONSTRATE KEY PATCH AND DEPLOYMENT REQUIREMENTS

STRIPES SOLVED SIMPLY WHERE STRUTS AND SPRING REQUIRED NEW LEARNING AND OPERATIONAL CHANGE

ENGINEERS CAN DIG TO EXPLOIT, BUT GETS OUT OF THE WAY FOR EVERYONE ELSE

LEGACY TO NEXT GEN

MAVENIZE APPLICATION END-TO-END

ALL SERVICES

ALL CONTENT

...EVERYTHING

WE’LL SEE SOME OF CONTENT AND LOGIC TONIGHT

STRIPES... AND JAVA WEB DEVELOPMENT IS FUN AGAIN*

COVERED

ACTION BEANS AND AUTO CONFIGURATION

EVENT HANDLING

LAYOUTS

VALIDATION

GET-AFTER-POST

NOT COVERED

SPRING BEANS, HIBERNATE (STRIPERSIST), ETC.

INTERCEPTORS AND STRIPES REQUEST LIFECYCLE

WIZARDS

* FREDDY DAOUD, AUTHOR

ACTION BEANS AND AUTO CONFIGURATION

STRIPES MAVEN QUICKSTART

NETBEANS BUG 208146

NOT IN MAVEN CENTRAL... YET. BUT SOON.

BASIC ACTIONBEAN

WEB.XML

SO? WONDER WHERE STRUTS 2 GOT THE IDEA?

EVENT HANDLING

STRIPES EVENTS ARE VIEW RESOLUTIONS

EASILY ENFORCES THE PRE-ACTION PATTERN IN MVC

BASIC ACTIONBEAN

ADVANCED ACTIONBEAN

RESOLUTION VARIETY

FORWARD, REDIRECT, JAVASCRIPT, STREAMING, ERROR... EXTENDABLE

LAYOUTS

STRIPES LAYOUT TAG LIBRARY

SIMPLE AND ROBUST

DYNAMIC

WEBLOGIC 10.X ISSUE AND WORKAROUND

SIMPLE EXAMPLE

COMPLEX EXAMPLE

VALIDATION

STRIPES VALIDATION GETS OUT OF THE WAY

ZERO, NADA, NO EXTERNAL CONFIGURATION

FULLY ANNOTATED IN ACTIONBEANS

NIGH INSTANT SERVER SIDE VALIDATION; EASILY COUPLED WITH CLIENT SIDE VALIDATION

DYNAMIC AND EXTENSIBLE

COMPLEX VALIDATION THROUGH

TYPE CONVERTERS

FORMATTERS

SIMPLE EXAMPLE

BASIC FIELD VALIDATION

COMPLEX EXAMPLE

OBJECT VALIDATION AND VALIDATION METHODS

GET-AFTER-POST

WHAT IS THIS... GET-AFTER-POST?

WHY?

HOW STRIPES MAKES IT EASY
