Ross Mason, founder of MuleSource expressed his frustration with OSGi: "OSGi is a great specification for middleware vendors, but a terrible specification for the end user." He argues that OSGi just isn’t ready for the developer yet as it is too difficult to completely make it invisible to a developer.
Recently the Deltacloud and libCloud projects were accepted into Apache incubator status. Now it looks like Nuvem, another Cloud-related project may be coming soon. Although there may be overlaps with these other projects, it seems that Nuvem may be taking a SOA-based approach with dependency on SCA.
WebSphere Application Server V7 Feature Pack for OSGi Applications and Java Persistence API 2.0 offers a standards-based implementation of OSGi Blueprint Container specification and JPA 2.0. It also provides an optional feature to deploy and manage applications as versioned OSGi bundles. IBM recently announced the GA release of the feature pack which is based on Apache projects Aries and OpenJPA.
A new version of the open source SCA implementation – Fabric3 - introduces many new features including improved clustering, deep integration with WebLogic application server, and improved performance support. InfoQ has conducted an interview with Metaform Systems founder and SCA contributor Jim Marino.
Service Component Architecture (SCA) is a today’s most popular programming model for building applications and systems based on a Service Oriented Architecture. A new “Assembly Model Specification Extensions for Event Processing and Pub/Sub” allows to further extend SCA’s reach in implementation of the event-driven systems.
The Apache Tuscany team announced the release of 2.0 M1 of the Java Service Component Architecture (SCA) project. SCA defines a technology neutral component and assembly model for business application developers to focus on implementing the business logic and composing them into business solutions without worrying about the technology concerns.
Complex Event Processing systems and Event Driven Architectures have been identified as playing a larger role in sophisticated systems today and in the future. What that role is and how it is carried out are up for debate.
SCA continues to gain momentum, becoming a dominant SOA programming model adopted by many commercial SOA products. Several recently published presentations explain capabilities, inner working and usage of SCA.
While in the past, the Java community debated over backing SCA or JBI, there are some signs that both of them might be formally incorporated into Java EE 6.
The Apache Tuscany team announced last month the 1.2 release of the Java SCA and 1.1 release of SDO projects. These releases make Tuscany implementation complaint with the main latest SCA specifications, including SCA Assembly Model, SCA Policy framework, SCA Java Common Annotations, SCA EJB, Spring, BPEL and Web Services bindings, etc.
At JavaOne 2008, Jos Dirksen and Tijs Rademakers talked about using Service Component Architecture (SCA) and Java Business Integration (JBI) frameworks together to get the best of both worlds. Using a sample application, they explained how to deploy an SCA application on a JBI container. In another SCA related session, Mike Edwards gave an overview of SCA architecture model.
The 0.9 draft of the SCA Java EE Integration specification, just published by the Open SOA collaboration, defines the integration of SCA and Java EE within the context of a Java EE application, the use of Java EE components as service component implementations, and the deployment of Java EE archives either within or as SCA contributions.
OASIS is going to hold a 3 day symposium on the topic of "Composability within SOA" in Santa Clara, CA from April 28th to April 30th. Engineers and Scientists from vendors and end-user companies will discuss topics including mashups, Service-Oriented Ajax, SCA, BPEL, SDO, BPM, Web Service Transactions, Data Security in SOA, SOA Reference Architecture...
Ever since the OpenSOA initiative published the white paper entitled: "Power Combination, SCA, OSGi and Spring", the combination of these three technologies has generated some interest. In a recent post, William Vambenepe explores potential new management capabilities for this type of SOA platform.
Paremus recently released version 1.2 of Infiniflow, a next-generation distributed application server based on OSGi and SCA. InfoQ spoke with Paremus Marketing Manager Andrew Rowney to learn more about this release and about Infiniflow's new application server model.
