JavaServer Faces is a Java-based Web application framework intended developed 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.

Frank Nimphius is a principal product manager for application development 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.

Sounds interesting.  Do you have any further info?

Group discounts are available for delegates from the same organization. The Sun Tech Days 2010 conference will be held at HICC, Hyderabad, India from March 24-25, 2010.

Java developers have to continually keep themselves updated about the latest developments in their field. Here is some good news for Java developers who want to give a boost to their career and stay ahead of others. The Sun Tech Days 2010 conference is going to be held at Hyderabad International Convention Center, Hyderabad, India from March 24-25, 2010.

The conference is unique in the sense that developers go through 50+ sessions, and interact with the brightest minds in the industry and learn about cutting-edge technologies, developments and ideas. There would also be hands-on labs and in-depth technology coverage to help developers improve their skills and boost their career.

Thanks for the reply. I looked at some of the Sun tech articles about Java Security Manager and not being the webmaster I don't completely understand all the action required to fine tune the Java security manager, and I don't have the access either 

I have not tried running JSE2 ver 5. Do you know if Ver 5 has different ways of handling or working around the security manager? 

Joe

Sorry, I don't know the answer to your problrm, but it sounds like it may be an issue with the Java security manager, and I would suggest that you investigate that area.

Have you tried running Java 5 instead of 1.4? There are a lot of speed improvements in this version that may help.

The organization I work for uses a centralized web-based Oracle (v10g) accounting program to monitor it's worldwide inventory. Our network has very strong firewalls and uses a lot of security software to insure network integrity. Users navigate to a portal website and login to their account where they post transactions and such. When users login and initiate a session we use Microsoft VM to create the virtual environment where we communicate with the accounting program. Microsoft VM works well in our environment and provides quick response times (seconds) as transactions are posted.

Understanding the real possibility that Microsoft VM might go away in the not so distant future we tried using Java 2 (Standard Edition) v1.4.2_13 (build-B06) to create the virtual environment and connect to our accounts. The response time was incredibly slow, it took minutes for the system to transition from screen to screen or provide any response to input.

As a test I bypassed our network and used a standard commercial ISP (cable) connection and Java 2 (Standard Edition) v1.4.2_13 (build-B06) to create the virtual environment then logged into my account. The response time I experienced using this connection was very fast.

My question is: How/why do the security settings of our network affect the system response time when using Java to create the virtual environment? 

Thanks for your help

You know I have been looking at several options and reading one of the blogs at sun I came across this site: http://www.jguard.net, they make JAAS authentication easier. Check it out. I ran across it today and I have not tested it, so I cant speak from experience, but I will try it myself on my application. Any how, good luck and I will post my experience with it. 

Hi,

I am new to web applications in JAVA, and securing them using JAAS. I found a lot of material and samples on Authentication and Authorization using JAAS. But I am unable to find any detailed material on Authorization using JAAS. I have a very basic requirement as follows.

When a Subject is Authenticated successfully I want to show a JSP with a menu that is customized for that Subject. The menu creation has to be done based on access permissions given to the Roles that Subject/Principal belong to.

I know there are many traditional and dirty ways to achieve this. But I want to make maximum use of JAAS to accomplish this. 

Can anyone point me to some good documentation on "Athorization" with JAAS, or some code samples? and any sample applications using tomcat I have already searched a lot on Java's website.

Thanks in advance
