Using Eclipse for Java Development Dr. Barry Burd Professor, Mathmatics & Computer Science Drew University |
The Eclipse development environment is great for both large and small projects. Eclipse has all the features of an industrial strength IDE, and can be customized for novice users. Eclipse's smart Java editor compiles code as you write. It provides hierarchical views of the class/method structure, and has hundreds of optional features and plug-ins. Best of all, this industrial-strength Java development environment is being developed by the open source community. It's free to use, and free to modify. |
|
Learning to use Hibernate Cris Holdorph Unicon, Inc. |
Persistence is a critical component to virtually any application built today. Technologies for accomplishing persistence are some of the most hotly debated topics in the Java industry. Hibernate has emerged as one of the most popular persistence technologies being used. This session will cover what Hibernate is, why it used and how to use it. The session will conclude with covering the recent Hibernate release and how Hibernate can be used with Spring. |

Service-Oriented Architecture with O.K.I Tom Coppeto OnTapSolutions Stuart Sim Sun Microsystems, Inc. |
Service-Oriented Architecture (SOA) is a software methodology that uses service contracts between service consumers and service implementations (providers). The goal of an SOA is to provide a framework in which business applications are interoperable in a wide variety of environments and service implementations can be shared among multiple applications. A separation of applications from the underlying implementation is essential to interoperability and leveraging working code.

Jumping In: Migrating an Enterprise System from Commercial Software to Open Source Jim Helwig University of Wisconsin-Madison |
Two years ago the University of Wisconsin-Madison was facing a major upgrade to their commercial portal software that would require significant resources and additional licenses. We took this opportunity to re-evaluate the software being used in the portal system. After a lengthy review process, the decision was made to migrate from the current commercial portal product to open source uPortal. While this was not the first instance of UW-Madison deploying open source software, it was the most significant deployment to date of an open source enterprise administrative system. This presentation will highlight how we approached the challenges faced when migrating a highly visible and critical enterprise system from a commercial software package to an open source system. |
|
A Holistic View of Identity Management Stuart Sim Sun Microsystems |
Identity Management has multiple components. uPortal customers are already implementing some Identity components like authentication (example Kerberos) and Web ISO (Yale's CAS).

Aggregation of WSRP channels on Eclipse Rich Client Platform Shoji Kajita Nagoya University |
This presentation investigates a client-side aggregation of channels by using WSRP based channels or tools on Eclipse Rich Client Platform (RCP) to seek a way to expand the client-side abilities to access to the institutional information services and resources and utilize them efficiently. Currently, any portal solutions like uPortal aggregate channels on server side, and Web browser performs the rendering on client side. However, the limitation of this scheme is obvious in the sense of the restricted usability of Web browser and the load concentration on server-side when hundreds of students are running simulation based educational materials. The Ajax technologies enhance the usability on client side by letting server-side platform and applications have more burden. Thus, any another technologies like Rich Client is going to be required to expand the ability on client side more and more. Although enhancing client side abilities would ultimately reach the notion of application grid for institutions', we need to address a lot of problems before
that, investigating the feasibility by using available technologies in institutions. In this presentation, we review WSRP, Eclipse RCP and its plug-in development, and then demonstrate the integration of Sakai WSRP
producers and Eclipse RCP to discuss the challenges and obstacles of client-side aggregation. |

Portal Postmortems - Investigating the Causes of Crashes Joseph Dane University of Hawaii |
Occasionally, inevitably, applications crash. Sometimes they do so under heavy load, when you can least afford to lose them. Joe will discuss techniques and tools, which can be used to diagnose performance problems in Java web applications such as uPortal. These techniques have been successfully used at the University of Hawaii to quickly find and fix critical bugs in the portal and other applications.

Enterprise Integration Update Adam Rybicki Unicon, Inc. Steve Wheat OpenEAI Software Foundation |
Enterprise Integration has historically been viewed as a difficult challenge to IT professionals. One of the reasons is that this challenge is viewed as Enterprise Application Integration (EAI), and solutions focus on applications invoking APIs of other applications. This approach requires integration professionals to learn APIs specific to the applications being integrated. With dozens or more applications to integrate, the integration professionals have to learn many vendor-specific APIs in different programming languages. Presentation (PDF) |

uPortal 2 Status Andrew Petro Yale University William G. Thompson Rutgers University |
A joint presentation between developers involved in uPortal 2.4.x, uPortal 2.5.x, and uPortal 2.6. |
|
Design and Development Scott Battaglia Rutgers University |
Application development is a process that if done correctly, can be a painless, enjoyable experience. If done incorrectly though, it can be one of the least enjoyable experiences, leading to exceeding budget, unhappy clients, feature creep, etc. Following the best practices of software engineering though can help alleviate these problems. This presentation discusses best practices of milestones, code reviews, early feedback, test driven design, etc. using Central Authentication 3.0 as the example project.

A Community-Source Student Information System? Leo Fernig University of British Columbia Richard Spencer University of British Columbia |
The issue of major open-source projects in higher education has taken on a new sense of urgency in light of the recent acquisitions of the major vended solutions. Senior administrators who are looking to replace a legacy SIS are faced with two equally unpalatable choices: either a high risk (and potentially unsustainable) custom development project or, alternatively, a costly and inflexible vended solution that is unlikely to be responsive to the unique needs of different institutions.

| Does Your Enterprise AAAS Have Good Guan Xi? Sean Mehan University of the Highlands and Islands |
This presentation reports on important tools and toolkits that support collaborative teaching and learning enterprise wide across elearning institutions, which is an important strategic objective for modern elearning. As part of the JISC Middleware Programme, the authors have developed and deployed a new OSS implementation of the Shibboleth extensions to the SAML vocabularies and profiles. There are a number of elements to the Guanxi developments, including an Identity Provider [IdP], a Service Provider [SP], and a SAML toolkit called SAMUEL [SAMl Used in eLearning]. These tools have already been deployed in several international courses for production teaching and learning, and the presentation will demonstrate the simplified installation and configuration of a Shibboleth compliant IdP which has been integrated into the Bodington VLE. Also, the presentation will cover the Shibboleth compliant, distributed SP which operates with an internal WS framework. The integration of the toolsets into multiple federations will be discussed. Finally, the authours will present important new Guanxi developments which will extend the SAML profiles to enable WS machine to machine authentication and authorizations in elearning.
