The term software factory is controversial. But think about it... No industry has experienced more innovation than the factory industries. On the contrary, the key to meeting demand is to stop wasting talents of skilled developers on rote and menial tasks...

Josh Bloch and Neal Gafter present yet another installment in the continuing saga of Java Puzzlers, consisting of eight more programming puzzles for your entertainment and enlightenment.

Java programmers now have a standard solution for creating and validating XML signatures. And with the progression of JSR 106 (Java XML Encryption API) through the Java Community Process, a standard solution for XML encryption will soon be available.

Groovy is an agile and dynamic language for the Java Virtual Machine. Builds upon the strengths of Java but has additional power features inspired by languages like Python, Ruby and Smalltalk. Makes modern programming features available to Java developers with almost-zero learning curve

OW2 Members present and demonstrate leading OW2 projects working together to provide a full-featured open source information system.

The conference covers a range of complementary middleware from OW2:

• Exo WebOS as the portal
• XWiki as the extensible wiki
• Bonita as the Workflow
• JOnAS as the application server
• SpagoBI as the Business Intelligence platform
• Talend as the Data Integration platform
• PEtALS as ESB and Service infrastructure platform
• Orchestra as BPEL orchestration engine
• Spagic as enterprise monitoring platform

Google Gears is an open source browser extension that lets developers create web applications that can run offline. During this presentation Dion Almaer will explain what Google Gears is and what the future usage will be within Google and other related partners.

Enterprises are deploying SOAs to gain business flexibility and efficiency. However when it comes to ensuring superior performance this approach and the technologies that underpin it, pose special management challenges. The loose coupling of services offers clear benefits - such as better alignment between business and IT; however, the complexities of service-orientation bring hidden performance risks. SOAs are simply the next generation of composite web applications, which CA Wily has been managing for over 9 years. They do have specific management challenges, but these must be considered in the context of the whole web application infrastructure through which Web services transactions flow.

In this session we will share our experiences, ideas, observations and thoughts on the real world impact and associated challenges of composite Web applications. We will take a close look at some of the key technologies and approaches behind a Service Oriented Architecture or SOA; and then focus on the Application Performance Management challenges associated with SOA.

This talk will provide a detailed view into a new platform IBM is building that is optimized for time and simplicity. This new platform allows you to build modern web applications easily and quickly with an event-driven, scripting centric programming model and an optimized runtime. This talk will provide an overview of the project and a detailed look at the programming model, including samples and demos. We will also discuss a new form of commerical software development being used with this project. To read up before the talk, check out www.projectzero.org .

Validating data is a common task that is copied in many different layers of an application, from the presentation tier to the persistence layer. Many times the exact same validations will have to be implemented in each separate validation framework, proving time consuming and error-prone. To prevent having to re-implement these validations at each layer, many developers will bundle validations directly into their classes, cluttering them with copied validation code that is, in fact, meta-data about the class itself.

This JSR will define a meta-data model and API for JavaBean validation. The default meta-data source will be annotations, with the ability to override and extend the meta-data through the use of XML validation descriptors. It is expected that the common cases will be easily accomplished using the annotations, while more complex validations or context-aware validation configuration will be available in the XML validation descriptors.

The validation API developed by this JSR will not be specific to any one tier or programming model. It will specifically not be tied to either the web tier or the persistence tier, and will be available for both server-side application programming, as well as rich client Swing application developers. This API is seen as a general extension to the JavaBeans object model, and as such is expected to be used as a core component in other specifications, such as JSF, JPA, and Bean Binding.

Apache ServiceMix is an Open Source ESB (Enterprise Service Bus) that combines the functionality of a Service Oriented Architecture (SOA) and an Event Driven Architecture (EDA) to create an agile, enterprise ESB.

Apache ServiceMix is an open source distributed ESB built from the ground up on the Java Business Integration (JBI) specification JSR 208 and released under the Apache license. The goal of JBI is to allow components and services to be integrated in a vendor independent way, allowing users and vendors to plug and play.
