Sat, 6 January 2007  Most of the attention around SOA has focused on its application to the
very largest enterprises. This focus is understandable - these
megacorps are the ones that have the most to gain or lose from a new
architecture (and also the biggest consulting budgets) - but it has
meant that the issues and requirements of smaller enterprises have
often been overlooked in SOA discussions. This is especially true in
areas such as governance, where the requirements of the largest
enterprises are very different from those of their smaller kindred.
Applying SOA guidelines based on requirements that aren't appropriate
for your business leads to governance bloat and bureaucracy. In this
presentation you'll see how to apply SOA in a more agile fashion to
allow small and mid-sized enterprises to gain the benefits of flexible
service components without the governance overhead often associated
with SOA. |
Sat, 6 January 2007 Web services are perceived as the ubiquitous solution to interoperable integration both within and across company boundaries. But despite their name, Web services don't build on the Web - on the contrary, to a large degree, they ignore the principles that have turned the Web into the world's most successful, scalable,distributed and loosely-coupled application. The presentation will introduce the principles of REST (REpresentational State Transfer), the Web's architecture, and address how to map advanced enterprise scenarios to an architecture that uses HTTP and the Web instead of abusing it.

Fri, 5 January 2007  With 17 sponsoring vendors, Service Component Architecture (SCA)
represents an important industry initiative to produce next-generation
service infrastructure. This talk provides an overview of SCA, focusing
on how SCA will impact technology strategy over the next two years. In
addition to discussing the evolution of SCA as an industry
collaboration effort, the talk covers the key elements of SCA,
including assembly and composition, service authoring, and policy.
Particular emphasis is placed on how SCA can be used to evolve existing
middle-ware investments to take advantage of SOA. |
Fri, 5 January 2007  Most large enterprises have launched an initiative to adopt
service-oriented architecture (SOA), but SOA is not a solution that
comes in a tidy little box. SOA is a new way to design systems, and it
is more about culture than it is about technology. SOA will impact many
aspects of an organization, from software development and operations to
accounting and incentive systems. Without some type of governance
program, a SOA initiative will almost certainly spiral out of control.
In this session, Burton Group Research Director Anne Thomas Manes will
discuss the fundamentals of a SOA governance program. |
Fri, 5 January 2007  We have proposed to add Closures to the Java Programming Language. Closures simplify the use of APIs that rely on the use of anonymous class instances, such as the concurrency APIs and callbacks. More importantly, closures support control abstractions, which are APIs that act as programmer-defined control constructs. This JavaPolis talk describes the proposed language extension and its design rationale, and shows how it will affect existing and future APIs. |
Fri, 5 January 2007  Patterns are widely accepted as a means to describe common ways of
architecture and design. In the book "Server Component Patterns"
(Wiley, 2002) we described component-oriented systems like EJBs as a
set of Patterns. This talk presents how Spring implements these
patterns and illustrates the new approach Spring takes towards
components. Also new Patterns in Spring like Exception Translator or
Template are presented. This shows the principles Spring uses for the
integration of different APIs and makes the design of Spring easier to
understand. |
Fri, 5 January 2007  Domain Driven Design (DDD) suggests dealing with complex software
system using a domain model and preserving the model in implementation.
Since domain model entities have rich behavior, so should their
software implementation artifacts. A direct mapping between domain
model and software artifacts create simple-to- understand,
inexpensive-to-implement, and easy-to-evolve systems. |
Fri, 5 January 2007  The recently-released EJB 3.0 specification has perhaps been one of the most talked-about technologies that has emerged from JCP for some time. At the center of attention is the Java Persistence API, a lightweight persistence model that acts as a point of convergence for the dominant persistence products currently on the market. Standardization of persistence inside of the Java EE platform, as well as in the SE environment, will finally provide enterprise applications with the ability to write to one API and be able to run on the vendor of their choice. This talk covers the core concepts of the API and describe how it can be used in applications. |
