particular service

How did you do that?
• I didn’t, Jen and Mark did, building on the
work of Pete and others.
• Pluggable DLM processing pipeline
• In dlmContext.xml:
<!-- Uncomment to enable AJAX preferences -->
<bean
class="org.jasig.portal.layout.dlm.remoting.AjaxPreferencesThemeParamInjector"
singleton="false"/>

Actually release 2.6
• Soon following this conference.

Platform Maturity
• uPortal Manual
• Convergence and consolidation of wandering
“contributions”
• Inversion of Control
• Codebase pruning
• API formalization
• Project formalization
![Page 50: UPortal 2.6 Andrew Petro JA-SIG Denver 25 June 2007 © Copyright Unicon, Inc., 2007. Some rights reserved](https://reader036.vdocument.in/reader036/viewer/2022062423/56649c925503460f9494d8f3/html5/thumbnails/50.jpg)
uPortal Manual wiki space
• Effort launched by Jason Shao
![Page 51: UPortal 2.6 Andrew Petro JA-SIG Denver 25 June 2007 © Copyright Unicon, Inc., 2007. Some rights reserved](https://reader036.vdocument.in/reader036/viewer/2022062423/56649c925503460f9494d8f3/html5/thumbnails/51.jpg)
Consolidation
• Neat channels and plugins out there
• “Contributions”
• Pull them into the core uPortal project
![Page 52: UPortal 2.6 Andrew Petro JA-SIG Denver 25 June 2007 © Copyright Unicon, Inc., 2007. Some rights reserved](https://reader036.vdocument.in/reader036/viewer/2022062423/56649c925503460f9494d8f3/html5/thumbnails/52.jpg)
How to spend deployer time
More valuable
• Incrementally involving
shared-source solutions
• Collaboration
• Evaluating working
examples
• The concept being
centrally proved
Less valuable
• Finding contributions
• Shoehorning them into
the portal
• Hacking at them to
make them work
• Moving on to the next
fire
• Building local POCs
![Page 53: UPortal 2.6 Andrew Petro JA-SIG Denver 25 June 2007 © Copyright Unicon, Inc., 2007. Some rights reserved](https://reader036.vdocument.in/reader036/viewer/2022062423/56649c925503460f9494d8f3/html5/thumbnails/53.jpg)

Invert Control - Concept
• *Not* go hog-wild changing everything
– We have working code
• But eliminate the number one impediment to
further incrementally improving uPortal
• uP2-uP3-CAS3 synergy – components for all
DI-able
![Page 56: UPortal 2.6 Andrew Petro JA-SIG Denver 25 June 2007 © Copyright Unicon, Inc., 2007. Some rights reserved](https://reader036.vdocument.in/reader036/viewer/2022062423/56649c925503460f9494d8f3/html5/thumbnails/56.jpg)
Invert control - Practice
• Spring WebMVC
– Controllers instead of Servlets
– Wire the most important services
• Synergy with contribution consolidation
![Page 57: UPortal 2.6 Andrew Petro JA-SIG Denver 25 June 2007 © Copyright Unicon, Inc., 2007. Some rights reserved](https://reader036.vdocument.in/reader036/viewer/2022062423/56649c925503460f9494d8f3/html5/thumbnails/57.jpg)

Embed CAS
• This is a really excellent idea, if I do say so
myself.
• uP security API feels dated. CAS3 feels
modern. Whole JA-SIG project around
authN.

Pick up CAS features
• Lots of authN provider
options
– LDAP
– Kerberos
– SPNEGO
– OpenID
– Google Account
–
• Lots of server flexibility
– I’d like three authN
methods, except on
Tuesdays
– Login workflow engine
• Documentation
• Discussion
• Scott answers your
questions

You mean you’re forcing CAS on me?
• No. I mean the most efficient way to
implement support for whatever you really
wanted to integrate with is to plug into CAS
rather than plugging into security.properties
• Though proxy tickets do have portal synergy

Migrate to Pluto 1.1
• If there’s a good reason to?
• “Pluto 1.1 aims to simplify the architecture in
order to make it more user and developer
friendly. You should find Pluto 1.1 easier to
get started with, easier to understand, and
easier to embed with your portal.”
• Sounds good to me, let’s do it.

API Formalization
• Just because Jan left the uPortal developer
community, doesn’t mean he wasn’t right.
• What are the “supported” APIs, and what are
incidental APIs?

How much theme can we share?
• CSS and images.
• Write skins, not structure and theme
transforms?

Build engineering?
• Eric, Scott, Elliott, etc. tell me that Maven2
works great
• Okay, let’s use that.
