ECF is a framework for building distributed servers, applications, and tools. It provides a modular implementation of the OSGi 4.2 Remote Services standard, along with support for REST-based and SOAP-based remote services, and asynchronous messaging for remote services. See the ECF Wiki for examples, tutorials, other documentation, as well as plans and efforts currently underway for future releases.

"The RHQ project is a systems management suite that provides extensible and integrated systems management for multiple products and platforms across a set of core features such as monitoring and graphing of values alerting on error conditions remote configuration of managed resources remote operation execution The project is designed with layered modules that provide a flexible architecture for deployment. It delivers a core user interface that provides audited and historical management across an entire enterprise. A Server/Agent architecture provides remote management and plugins implement all specific support for managed products. RHQ is an open source project licensed under the GPL, with some pieces individually licensed under a dual GPL/LGPL license to facilitate the integration with extended packages such as Jopr (now included in RHQ) and Embedded Jopr."

Apache XML-RPC is a Java implementation of XML-RPC, a popular protocol that uses XML over HTTP to implement remote procedure calls. Version 3 of Apache XML-RPC is still compliant to the XML-RPC specification. However, the user may enable several vendor extensions are available, that greatly extend the power of XML-RPC: All primitive Java types are supported, including long, byte, short, and double. Calendar objects are supported. In particular, timezone settings, and milliseconds may be sent. DOM nodes, or JAXB objects, can be transmitted. So are objects implementing the java.io.Serializable interface. Both server and client can operate in a streaming mode, which preserves resources much better than the default mode, which is based on large internal byte arrays.

Apache Axis is an implementation of the SOAP ("Simple Object Access Protocol") submission to W3C. From the draft W3C specification: SOAP is a lightweight protocol for exchanging structured information in a decentralized, distributed environment. It is an XML based protocol that consists of three parts: an envelope that defines a framework for describing what is in a message and how to process it, a set of encoding rules for expressing instances of application-defined datatypes, and a convention for representing remote procedure calls and responses. This project is a follow-on to the Apache SOAP project. Please see the Reference Library for a list of technical resources that should prove useful.

SymmetricDS is web-enabled, database independent, data synchronization/replication software. It uses web and database technologies to replicate tables between relational databases in near real time. The software was designed to scale for a large number of databases, work across low-bandwidth connections, and withstand periods of network outage. By using database triggers, SymmetricDS guarantees that data changes are captured and atomicity is preserved. Support for database vendors is provided through a Database Dialect layer, with implementations for MySQL, Oracle, SQL Server, PostgreSQL, DB2, Firebird, HSQLDB, H2, and Apache Derby included. Synchronization can be configured to push data (trickle-back) or pull data (trickle-poll) at an interval. SymmetricDS allows for synchronization between two or more tiers of nodes, such as the following: A farm of web server nodes fronting an enterprise-class general office database A handful of regional servers for synchronizing from the general office to remote geographical areas 1000(s) of store server nodes using a departmental class database to sync with a regional node 10(s) of Point of Sale (POS) register nodes using an embedded database to sync with a store server Deployment options include the following: Web application archive (WAR) deployed to an application server such as Tomcat, Jetty, or JBoss Standalone service Embedded in an application SymmetricDS is written in Java and licensed as open source software under the GNU Lesser General Public License (LGPL).

" Registered 2008-09-26 by Michael Terry Déjà Dup is a simple backup tool. It hides the complexity of backing up the Right Way (encrypted, off-site, and regular) and uses duplicity as the backend. Features: * Support for local, remote, or cloud backup locations, such as Amazon S3 or Rackspace Cloud Files * Securely encrypts and compresses your data * Incrementally backs up, letting you restore from any particular backup * Schedules regular backups * Integrates well into your GNOME desktop For Ubuntu users, there are three ways to get Déjà Dup: * Supported releases: http://apt.ubuntu.com/p/deja-dup * Stable release backports: https://launchpad.net/~deja-dup-team/+archive/ppa * Daily builds: https://launchpad.net/~deja-dup-team/+archive/testing If you are interested in contributing, there are many ways to help: * http://live.gnome.org/DejaDup/GettingInvolved"

" Given that web service invocations are always remote across the internet, developing rigorous and responsive web service client applications has always been a challenge for architects and developers working with SOA. JAX-WS 2.0 comes with one effective solution to this problem: asynchronous web service invocation, with which a web service client may interact with a web service in a non-blocking, asynchronous approach. In this article, we will provide an exposition of this technology with examples built upon the reference implementation. Our examples utilize JDK 5.0, JAX-WS 2.0 reference implementation (RI), and Tomcat 5.5. JAX-WS 2.0 requires JAXP 1.3. To replace the JAXP 1.2 released with JDK 5.0 with this newer version, one approach is to download the JAXP 1.3 RI, and copy the endorsed directory under /lib of its installation home to %JAVA_HOME%/jre/lib. We need to copy the jaxp-api.jar of JAXP 1.3 RI to %JAVA_HOME%/jre/lib/endorsed as well. To make Tomcat 5.5 work with JAX-WS 2.0, readers need to copy all the .jar files under the /lib directory of the JAX-WS 2.0 RI installation to the %CATALINA_HOME%/shared/lib directory. As of this writing (in addition to Tomcat 5.5), Sun Java System Application Server 9.0, GlassFish, and Celtix also support JAX-WS 2.0. xFire is in the process of completing its implementation of this specification. Since asynchronous web service invocation in JAX-WS 2.0 is built upon the concurrent programming support in JDK 5.0 introduced with the java.util.concurrent package, we will start from there."

This blog host some of the good article on Java, FIX Protocol and Tibco Rendezvous messaging. I have shared Interview questions, daily tips, commands and approach on how to increase productivity and work effectively with these technology.
