Bringing Web 2.0 to Webtop MWDUG March 23, 2006
The opening credits • Sean Iams • siams@tsgrp.com • The Talent • Todd Pierzina • tpierzina@tsgrp.com • Manager Hair Potential
Web 2.0 and Webtop in 75 min. • Problem definition • Web 2.0 • A potential solution • Almost-Live Demo • “Making Of” documentary • Discussion
I love working with my boss, but… • So many great things! • TODO: Think of some great things • Some things could be improved… • POWERPOINT OVERFLOW:Too many list items.
I love working with Webtop, but… • So many great things! • It’s not RightSite! • Elegant development framework • Extensible • Flexible • Standards-based • Some things could be improved… • Performance • Performance • Performance
I’m a lover, not a hater! • The WDK framework is incredibly complex • The most aggressive caching cannot overcome: • Complex user, group and ACL structure • Complex object model and business rules • Networks with “issues”
Just one real-life example • Johnson & Johnson has just launched OneSource 2.0 • Based on Webtop 5.3SP1 and TSG’s Active Wizard 3.4 • Users love the functionality! • Here’s a sample properties page…
Object properties page Several layers of cascading value assistance Multiple, often painful, screen refreshes An actual screenshot!
C’mon, we need fancy Web 2.0 to solve THIS? • We could load everything up front in JavaScript • Recode business rules in JavaScript • Could be a long page load time • No cascading value assistance—rather, do a “post-check” • Could be good for a small set of knowledgeable users • Again, long page load time • Could be duplicating business rules already defined in docbase
Some web-geek definitions • JavaScript • Scripting programming language supported by just about every web browser, PDA—maybe even your microwave • XML (Extensible Markup Language) • Everything XML, all the time! • Ajax (Asynchronous JavaScript and XML) • The “heart and soul” of Web 2.0, at least so far • JSON (JavaScript Object Notation) • Non-XML alternative to Ajax
Why is this stuff hot now? • Common browsers support necessary technologies • Nobody uses IE4 anymore • Easier to control platform on intranet/internal projects • How’d they do that? • Google Maps, Yahoo Maps • Yahoo! Mail (beta) • Del.icio.us • Etc.
Almost-Live Demo • “Before Ajax” and “After Ajax” • Not a realistic environment! • No network lag • Simple object properties • Small amount of test data • But let’s look anyway…
Under the Hood • Single registered table • Component and Docbase Object Configuration files • attributes_dm_document.jsp • OOTB except for JavaScript at top • ContentLoader JavaScript would come out into an external web resource • A small amount would be custom to each object
And the heavy lifters… • Picklist.java • Actually does all the work, gets zero credit • Kind of the Sean Iams of this POC • AjaxDocbaseAttributeValueTag.java • Used by customized docbaseobjectonfiguration_dm_sysobject.xml • AjaxDropDownListTag.java • Helper class for the Value Tag • Actually constructs HTML • GetPickListServlet • Used for “onchange” events
Wrap-up • Potential gotchas • Minimum browser requirements • Upgrade-friendly? • Minor upgrades • Major upgrades • Where else in Webtop might this apply? • Re-paging and re-sorting folder contents • Others?
The End • Questions? Items for discussion? • This presentation will be posted on www.mwdug.com. • We’d love to open a dialogue with one and all…here today and beyond. • Again, I’m tpierzina@tsgrp.com, 312.372.7777 x254.
