Eclipse Virgo Release Candidate Submitted by gnormington on Tue, 2010-10-19 08:08
in
A Release Candidate (2.1.0.RC1-incubation) of Eclipse
Virgo is available from the
download page. A User Guide, Programmer Guide, and a tutorial entitled "Creating an Application with Virgo" are available from the
documentation page. You may also like to read a quick
summary of features or an "elevator pitch" on the
benefits of Virgo.
The Eclipse-based Virgo application development tooling may be installed into Eclipse as
described in the Programmer Guide or installed as part of the SpringSource Tool Suite as
described in the tutorial.
Please
raise a bugzilla if you find a bug.
Unless a major bug is found, or one which impacts a broad range of users and for which there is no reasonable workaround, RC1 will turn into 2.1.0.RELEASE by the end of October 2010.
SpringSource Tool Suite 2.5.0.RC1 released Submitted by Christian Dupuis on Fri, 2010-10-15 03:58

SpringSource has just released a new milestone version of SpringSource Tool Suite: 2.5.0.RC1. STS provides the best Eclipse-powered development environment for building Spring and Grails powered enterprise applications.
The release comes only a few hours after we pushed Spring Roo 1.1.0.RC1. STS 2.5.0.RC1 certainly supports the new Roo version and comes with lots of improvements in the Roo and GWT support.
This is also the first time we are providing bundles based on Eclipse 3.6.1. If you aren't quite ready to try the cutting edge milestone release, then you can always download the 2.3.2.RELEASE version.
You can also get community support in the
Spring Development Tools support forums. If you want to provide direct technical feedback, open a
JIRA issue against the SpringSource Tool Suite project.
Downloads are available - as always - from our
STS download page. Enjoy!

Just some of the properties of new, modern applications are that they tend to be highly interactive, data rich, include business processes, and are available over the web from PCs and mobile devices. Powering these applications are platforms that leverage virtualized infrastructure, provide just the right amount of functionality and can scale easily as demand shifts.
VMware’s vFabric Cloud Application Platform is just such a platform designed to run Spring applications most efficiently and deliver the modern application experience. An essential component of this platform is
vFabric GemFire. vFabric GemFire in-memory distributed data management brings data to applications with low latency, high reliability and linear, dynamic scalability. We are pleased to
announce vFabric GemFire version 6.5.
- Newly redesigned APIs (and samples) combined with the Spring GemFire integration project dramatically improve the developer experience
- Shared Nothing parallel persistence with backup and recovery provides database reliability without the performance bottleneck
- Improvements in areas like subscription processing bring cloud scale to applications
More detail on vFabric GemFire 6.5 is available on from the blog of chief architect,
Jags Ramnarayan.

ChangelogEclipse Virgo: the ideal OSGi server runtime? Submitted by gnormington on Mon, 2010-10-11 09:48
in
Since we switched from the SpringSource team blog to this site for publicising updates to Eclipse
Virgo, traffic to the Virgo web site has increased considerably with a large proportion of new visitors. So it seems that many readers of this site may not have heard of Virgo before. If that includes you, please read on.
Essentially Virgo is the culmination of 3 years of work in developing an application server based entirely on
OSGi and exposing OSGi for use by applications. Virgo started inside SpringSource as the
dm Server project which was licensed under the GNU Public License and shipped two major versions. About a year ago we started donating the codebase to Eclipse as the Virgo project licensed under the much more liberal Eclipse Public License. The transfer of the runtime code to Eclipse is now complete, we have satisfied the rather stringent IP checks required of all Eclipse projects, and Virgo is nearing its first formal release by the end of October.
Virgo is an ideal OSGi server runtime, possibly
the ideal OSGi server runtime, from several perspectives. Firstly, it was
designed from the ground up as OSGi bundles so it's extremely modular and extensible. For example, the core of the runtime is the Virgo kernel and the Virgo web server is constructed by configuring a web layer, an admin console, and some other utilities on top of the kernel. The kernel protects itself from interference from such additions, and applications, by running them in a nested framework. This nested framework approach also enables applications to use new versions of the Spring framework (regardless of the fact the kernel depends on Spring 3.0.0). All the major Java EE application servers are now built on top of OSGi, but only Virgo was
designed for OSGi and didn't need OSGi to be retrofitted.
Secondly, Virgo is an ideal OSGi server runtime because it
exposes OSGi in a usable way to applications. In addition to all the standard features of OSGi — encapsulated modules or
bundles, a powerful service registry, versioning, class space isolation, sharing of dependencies, dynamic refreshing and updating, and much more — Virgo provides a multi-bundle application model to simplify the deployment and management of non-trivial applications. Virgo also provides a repository which can store dependencies such as OSGi bundles which are "faulted in" when needed. This results in cleaner definitions of applications and a small footprint compared to traditional Java EE servers which pre-load many features just in case an application needs them. The major Java EE application servers are beginning to follow suit in exposing an application model, so SpringSource is working with other vendors in the OSGi Alliance to produce a standard multi-bundle application construct.
Thirdly, Virgo is an ideal OSGi server runtime because it
enables existing Java libraries to run successfully in an OSGi environment. The Virgo kernel supports thread context class loading, load time weaving, classpath scanning, and a number of other features which are commonly used by persistence providers and other common Java utilities. Essentially, we observed the commonly-occurring problems when people attempted to migrate to OSGi and implemented general solutions to those problems early on.
Fourthly, and perhaps of particular interest to this audience, Virgo is an ideal OSGi server runtime because it
integrates OSGi with Spring and Tomcat. Virgo uses
Spring DM to wire application contexts to the OSGi service registry. Spring beans can be published as OSGi services and can consume OSGi services, both with minimal effort. The embedded form of Tomcat is used as a servlet engine in Virgo's web support and is configured and managed just like standard Tomcat.
Fifthly, Virgo is an ideal OSGi server runtime because of its
excellent diagnostics:
- An admin console lets you examine the state of all artifacts deployed in Virgo as well as explore the state of bundles in the OSGi framework.
- Virgo provides multiple types of diagnostics: event logging aimed at administrators, diagnostics logging aimed at developers, as well as various types of diagnostic dumps.
- Virgo builds on Logback to support highly configurable and efficient logging.
- When an application is deployed, Virgo first resolves the application in a "side state" and, if resolution fails, no changes are committed to the OSGi framework and the side state is dumped to disk so that it can be analysed using the OSGi state inspector in the admin console.
- If a resolution failure occurs, Virgo also analyses the resolver error, including the root causes of any uses constraint violation, and extracts a meaningful message to include in an exception which is then thrown.
- Virgo adds advanced diagnostics to Spring DM to track the starting of bundles and their application contexts and issue error messages on failure and warnings when dependencies are delayed.
- Virgo automatically detects deadlocks and generates a thread stack dump.
Finally, Virgo is an ideal OSGi server runtime because it has
advanced tooling support in the
SpringSource Tool Suite or in standard Eclipse via an
update site. This enables a Virgo server to run under the control of the tooling, applications to be deployed, debugged, and updated by the tooling, and package and service dependencies between bundles to be analysed. The Virgo tooling will also be donated to Eclipse in due course.
Oh, I almost forgot to mention the obvious: Virgo is an
open source project with a
liberal license and
active participation from multiple vendors, which positions it ideally for the future.
