Building Web 2.0 UIs with JSF, Realtime Updates with JSF and Ajax
Shaguf
to simplify development integration of Web-based user interfaces. It is often
mentioned together with Ajax, a combination of technologies that makes it
possible to create rich user interfaces. Since JSF supports multiple output
formats, Ajax-enabled components can easily be added to enrich JSF-based user
interfaces. Oracle's Frank Nimphius says that Service Oriented Architecture
(SOA) has become a reality in modern software development but Web services
don't have a user interface. This is fine if communication is between
machines. But what about human interaction like in data entry and work flow?
Users need an application display they feel comfortable working with. So what
about building Web 2.0 user interfaces for service oriented architectures?
Does it work, or does it hurt - and if so, how bad is it? Frank is coming
this summer to India's biggest summit for the software developer ecosystem -
Great Indian Developer Summit (http://www.developersummit.com/) to show how
JavaServer Faces can be used to build compelling Ajax user interfaces for Web
Services models giving end users a comfortable working environment that
includes client side validation and user interface customization.
In his second session at GIDS 2010, Frank addresses the topic of
implementing automatic UI refreshes. To web application users, it must appear
as if the Web reinvents itself once a year with more interactive UIs,
increasing performance through partial page refreshes, and desktop-like
usability patterns that allow users to become as productive using web
applications as they are using real desktop clients. One technical detail,
though, hasn't changed in the past and is unlikely to change in the near
future: HTTP. Hypertext Transfer Protocol is based on the request-response
principle in which the client sends a query to the server and the server
responds with the requested data. Between requests, no connection is
maintained between the client and the server that would allow server-side
logic to send more data unasked. Any changes in the underlying data layer
used by an application are first detected within the next client request.
Hopefully, it doesn't come to you by surprise when we say that in the modern
days of Web 2.0 and Rich Enterprise Applications (REA), the Web still is
disconnected and stateless. So, in these modern days of Web 2.0 and Rich
Enterprise Applications (REA), is the Web still is disconnected and
stateless? Not really, because you frequently use some applications on the
Web that update their client UIs with server-side changes without your
needing to do anything. The question, therefore, is how this was accomplished
and whether you can do the same in JavaServer Faces. In his session, Frank
will guide attendees through the options that are available in AJAX and other
implementation technologies of Rich Internet Applications (RIA) to implement
automatic UI refreshes.

tools at Oracle Corporation since 1999. He actively contributes to the
development of Oracle JDeveloper and the Oracle Application Development
Framework (ADF). He represents the Oracle J2EE development team at J2EE
conferences world wide, including various Oracle user groups and the Oracle
Open World conference. The talk 'Building Web 2.0 User Interfaces for Web
Service Models using JSF' will be co-presented by Jobinesh Purushothaman.
Jobinesh Purushothaman is an enterprise Java specialist with 10+ years of
experience in the industry. He is involved in design and architectural
decisions of various products using ADF and JavaEE technologies. He is
interested in developing more simplified enterprise technologies where
developers can focus on their business solutions rather on the technology
complexities.
