With modern languages and tools, legacy code conversion is quite simple. The impediments are simply managerial in nature. No one wants to have a carefully maintained piece of software declared a liability and discarded. Everyone wants to think of it as an asset that will be carefully preserved.
I posted before about how to create a mock service when you have a JDK 1.6 or higher available. Of course there are a lot more options to mock web services (one I used often is the option supplied by SoapUI). This post shows a way to mock a web service by using a WSO2 Proxy Service.
I understand that certification is not for everyone, but in my case I felt that because SOA is surrounded by so many myths, legends and falsehoods, it probably makes sense for me to add a quality mark to my work for my clients.
I learned about Xpath 5 years ago, but I've really only seen enterprise usage in just the past few weeks. Therefore, I wanted to write about Xpath 2.0 and the enterprise experience.
Anyone that has used DevKit to write a Mule extension and then wanted to add it to Studio, may have notice that the extension will appear under the Cloud Connectors category in the palette. This is not a problem when the extension is actually a Cloud...
I attended the SATURN 2013 conference in Minneapolis a couple of weeks ago, which is an annual practitioner conference about software architecture, organised by the Software Engineering Institute (SEI) of Carnegie Mellon University.
In this last part I want to show you creating your own media type, so far we have gone over a really basic example of returning a response and letting the accept header handle different results, and then we went over how explicitly using Negotiate allows you to customize your response more.
I have worked on ActiveMQ for quite a while, and there’s one annoying exception that I see all the time – java.io.IOException: Too many open files – which we see time to time.
I’m thrilled to announce the availability of CloudHub in Europe. With this announcement, we’re extending the industry-leading CloudHub platform to address the needs of our European customers with dedicated computing resources located in the European Union.
A successful system is going to need upgrading periodically. The user's requirements might change over time, different users might want to use the system, external interfaces may change and, of course, software salespeople will want a reason to charge upgrade fees (I'm such a cynic).
JMS 2 is one of the most significant parts of Java EE 7. One of the principal goals of the JMS 2 API is improving developer productivity by reducing the amount of code to work with JMS
It takes effort, persistence & contributions from a lot of folks to build a truly rewarding developer community that benefits everyone involved. This will be a quick post thanking several people that I truly respect & enjoy working with, along with thoughts on running a technical User Group.
With the explosion of APIs, the Enterprise has flung open its doors and windows and ripped off its roof in order to reach to the sky to exploit the vast array of cloud-based services on offer and include them in its software inventory.
This post will illustrate error handling in wso2 esb in regards to Endpoints. It's an import topic to cover because WSO2 Enterprise Service Bus needs to send the message to a service provider in its final stage.
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?
