From the OpenStack summit comes a lightning talk presentation on an implementation within the OpenStack IaaS software using the ZeroMQ message broker and Grizzly, the NIO Event simplifying framework.
Enrich Mediator can be used to perform transformations with in integration logic. It process a message based on a given source configuration and perform the specified action on the message by using the target configuration.
A Domain-Specific Language (DSL) can provide some intellectual leverage. We can always write long and convoluted programs in a general-purpose programming language (like Python, Java or C). Sometimes it can make more sense to invent a new domain-specific language and implement the solution in that language.
I do not think the agile approach diminishes modeling, in fact I think it increases the modeling because before the start of every development cycle, modeling must be checked for accuracy based on the changed requirements.
Pieter Hintjens, a maintainer of ZeroMQ: The Definitive Guide, discusses the patterns, the code, and the community behind this message-passing library.
This simple tutorial will lead you to write proxy with WSO2 ESB Payload Mediator. Here is the client sending request payload for proxy...
I am not recommending a specific language over others at this time, but providing a long list of languages based on GitHub and TIOBE.
As I thought about it I realized that it isn’t important for it to be a language that you learn, it is just important that you learn something new. Experiment with a new platform, study data theory, join the enemy’s camp and understand their point of view.
Paul Hammant takes a broad look at the anti-software patent organizations, old and new, and where we are right now in the process of affecting real change in US software patent laws.
According to Microsoft, ODBC is a specification for a database API. This API is database and operating system agnostic due to the fact that the primary goal of the ODBC API is to be language-independent.
Good companies realize they need to involve their engineering team to help recruit. That could mean hosting drink ups, sending the team to conferences and old fashioned professional networking. But what about your engineering blog?
Venkat Subramaniam at a talk today mentioned about Cascade Method pattern or Train Wreck pattern which looks something like:someObject.method1().method2().method3().finalResult()
In a race to optimize everything, developers often go to extremes to build software that performs routine tasks. MissionControl is a system that allows users to program a control center that stores interfaces with attached hardware sensors, allowing the users to control any other devices that can be activated via the underlying protocol.
This post will be for WSO2 ESB Filter Mediator and it will be cover simple usecase with basic Filter Mediator functions. It can be used for XPath filtering of messages.
I recently integrated Google Calendar into a Wicket application I use at home. As some requirements are atypical I want to describe them before going into too much detail...
This week marks the launch of my lingering weekend-project: scalabitz.com. It tries to surface interesting Scala content through the API of link-shortener Bit.ly. The site was built using Scala and Play (and a bit of Akka) with a MongoDB storage layer and can be found on GitHub.
If you have a new web project or and existing Drupal site, the combination of Drupal and Apache Solr is both powerful and easy to set up thanks to the existing integration code. The module allows for substantial customization with the administrative UI.
Originally mainframe architectures relied on a centralized host server that processed data and returned it to be displayed on a dummy terminal. These dummy terminals did not have my processing power and could only display data that was sent from the mainframe.
scala-zeromq facilitates communication using the ZeroMQ messaging library. ZeroMQ is a message-oriented socket communication library that support several high-level messaging patterns, including request-reply, publish-subscribe and push-pull. This is good since the current Akka extension for ZMQ has issues.
How do you design and deploy a hybrid cloud application service using Openstack, VMware Vcenter and HP Public Cloud Service? How do you automatically scale your multi-tier application to respond to peak demand?
This session will present a case study focusing on the development of a robust, horizontally scalable, enterprise CRM system at Dealer.com built primarily upon a Spring technology stack.
There’s a lot of hype around door-to-door travel search. To be fully capable of providing user awesome travel search results, not just from airport to airport, these companies will need to plug in content from different sources including flights, trains, ferries and ground transportation.
Have a look at my configuration that will respond to the client after a SOAP request is sent to a JMS queue.
It is a common scenario that an API Server must call out to a Security Token Service (STS) "off to the side" in order to get a SAML assertion issued for a user. This SAML Assertion then then usually inserted into the request, often as a HTTP header. Let's see how this is done with the Axway/Vordel API Server...
A common question about the Axway/Vordel API Server is "How do you change its listening port?". The key to answering this question is to understand what are the "Services" groups under Policy Studio for the API Server:
