The Java EE 7 specification has evolved quite a lot since the early days of the specification. One one hand, Java EE 7 continues the ease of development push that characterized prior releases by bringing further simplification to enterprise development. On the other hand, Java EE 7 tackle new emerging requirements such as HTML 5 support.
Last but not least, Java EE 7 also adds new, APIs such as the REST client API in JAX-RS 2.0, WebSockets, JSON-P, JMS 2, Batch Processing, etc.
This session will give an technical overview of the Java EE 7 platform. GlassFish 4.0, the world first Java EE 7 Application Server, will be used to demonstrate some of the Java EE 7 features.

Reusing Existing Java EE Applications from SOA Suite 11gGuido Schmutz
You have a lot of existing Java EE applications. Part of these applications and their logic have a potential to be reused in an SOA. But what is the best practice for reusing such Java EE applications? This session will show different approaches available with SOA Suite 11g in the SCA assembly model as well as with the Oracle Service Bus to reuse existing Java EE artifacts.
PL/SQL developers (as well as DBAs and many others involved) typically are uncertain what SOA means to them. They feel overwhelmed by a avalanche of acronyms. Yet they see it coming and instead of being surprised or bypassed, this session allows them to start participating and benefiting themselves. This session introduces SOA and the Oracle SOA Suite 11g to the realm of the PL/SQL developer - from which it sometimes seems so far removed. What are the key SOA concepts and objectives - what's the buzz about? What is at the heart of SOA Suite 11g: Composite Applications, BPEL PM and the Mediator.
The presentation demonstrates how SOA Services can be leveraged from the database – from Triggers and PL/SQL applications and how the database can publish events to the Event Delivery Network. It demonstrates how the SOA infrastructure can access the database, primarily using the Database Adapter – and how database developers can be instrumental in efficiently doing so. It concludes with some hints for applying SOA concepts for 'normal' database development.

What is at the heart of Oracle SOA Suite 11g: composite applications, BPEL PM, and the mediator. The session shows how SOA services can be leveraged from the database, from triggers, PL/SQL units, or even SQL and how the database can publish events to the event delivery network. It covers how the SOA infrastructure can access the database, primarily using Oracle Database and Oracle Advanced Queueing adapter and how database developers can help in doing so efficiently. It ends with hints for applying SOA concepts to "normal" database development.
Where and when to use the Oracle Service Bus (OSB)Guido Schmutz
The Oracle Service Bus (OSB) is part of the Oracle SOA Suite 11g and stands in the center of modern process- and integration-solutions. The lightweight, stateless and high-performant architcture of the OSB turns it into an excellent tool for doing transformation and routing of messages. This presentation explains where and when the usage of the OSB makes sense but also shows the limits of the OSB.

One of the attractive qualities of OSGi is its role in enabling technologies that adopt it to manage the cost of their own success. Anything that gains adoption - in technology or elsewhere - picks up baggage as a result and needs to figure out how to deal with current installations while expanding in new directions. The WebSphere platform has been around for almost as long as Java and knows a thing or two about baggage but still manages to travel to many places with just a carry-on allowance. We adopted OSGi internally 8 years ago and have gradually increased our exploitation with each passing release, most recently and deeply with the lightweight WAS Liberty Profile. It hasn't all been plain sailing and we learned from a number of mistakes made along the way. When WebSphere Application Server first adopted OSGi it had over 10 million lines of code in a modest number of huge JARs. The engineering effort to modularize that into a “sensible” number of OSGi bundles was fairly significant. We had a global development team spread across a dozen labs and nearly as many timezones, all learning OSGi principles at the same time. What could possibly go wrong? We did not, for example, initially adopt the services part of the OSGi architecture but it’s how we can now start/stop individual technologies of the Java EE Web Profile on the WAS Liberty profile, in a 50MB install with a 2-second startup, while still supporting a massive deploy base of applications on older levels of Java EE.
One of the challenges OSGi continues to face is over when to be “front of office” and when to be “back”. As the industry accelerates towards cloud, OSGi is an internal part of IBM’s strategy for high-density virtualized Platform-as-a-Service through WebSphere Liberty. Today’s cloud provisioning strategies, for example the buildpacks used by Heroku and CloudFoundry, are designed to be technology-agnostic. As a programming model for the cloud, OSGi is in a position of strength with its heavily service-oriented architecture. But in the spirit of agnosticism, one of the next steps OSGi needs to take is simply greater availability of the core OSGi framework in some of the more popular cloud platforms. Once there are more OSGi services running in those environments then the value and simplicity of autowiring OSGi services as cloud services becomes more apparent. Expectations and vision has to be managed up and down any organization that invests in OSGi - from the executive leadership team responsible for the business's bottom line, through the distributed architecture/development teams building tomorrow's technology on top of today’s, to the marketing and sales organization who need to sell the result to both IT and line of business. The value proposition has to be tailored to the audience.
This is the story of how WebSphere has had outstanding success with the former four-letter acronym that IBM Marketing still wants to expand.

OSGi Community Event 2013 (http://www.osgi.org/CommunityEvent2013/Schedule)
ABSTRACT
One of the attractive qualities of OSGi is its role in enabling technologies that adopt it to manage the cost of their own success. Anything that gains adoption - in technology or elsewhere - picks up baggage as a result and needs to figure out how to deal with current installations while expanding in new directions. The WebSphere platform has been around for almost as long as Java and knows a thing or two about baggage but still manages to travel to many places with just a carry-on allowance. We adopted OSGi internally 8 years ago and have gradually increased our exploitation with each passing release, most recently and deeply with the lightweight WAS Liberty Profile. It hasn't all been plain sailing and we learned from a number of mistakes made along the way. When WebSphere Application Server first adopted OSGi it had over 10 million lines of code in a modest number of huge JARs. The engineering effort to modularize that into a “sensible” number of OSGi bundles was fairly significant. We had a global development team spread across a dozen labs and nearly as many timezones, all learning OSGi principles at the same time. What could possibly go wrong? I’ll spend a little time reviewing the consequences of our bundles-first-services-later approach but our success was initially limited to having the equivalent of a well-organized and large container ship which could travel at speed but needed a pretty wide berth. Our initial investment in OSGi delivered on most of the internal benefits we wanted but failed on some of the external ones that matter to our customers.
Application Servers are used in different ways by Developers and IT Operations. Ops teams care about the overall cost, including performance and availability, of the platform and the applications it supports; Dev teams care about how quickly and easily they can create and deliver their applications and treat the server as a tool. Only some of them know or care about OSGi; multi-channel enablement and cloud deployment are the current pressures they are under. Today, WebSphere is a consumer of OSGi in two distinct fashions. Internally we learned from our earlier experiences and embraced an OSGi services model to enable us to run the same runtime just as fast but in a far more dynamic fashion: it’s how we can start/stop individual technologies of the Java EE Web Profile independently on the WAS Liberty profile, in a 50MB install with a 2-second startup while still support all our customers’ existing deployments. Externally we support both Enterprise OSGi and traditional Java EE as application programming models, on the same runtime and using the same Eclipse-based tools. Our customers who understand and care about OSGi can develop and deploy web application bundles and multi-bundle enterprise applications. Those who don’t care about OSGi benefit from it ind

Graspan: A Big Data System for Big Code AnalysisAftab Hussain
We built a disk-based parallel graph system, Graspan, that uses a novel edge-pair centric computation model to compute dynamic transitive closures on very large program graphs.
We implement context-sensitive pointer/alias and dataflow analyses on Graspan. An evaluation of these analyses on large codebases such as Linux shows that their Graspan implementations scale to millions of lines of code and are much simpler than their original implementations.
These analyses were used to augment the existing checkers; these augmented checkers found 132 new NULL pointer bugs and 1308 unnecessary NULL tests in Linux 4.4.0-rc5, PostgreSQL 8.3.9, and Apache httpd 2.2.18.
