This is the second post of the two part series. The first part covered the life cycle and the concurrency behavior of Stateful and Stateless EJBs. I’ll cover Singleton EJBs in this post. The Singleton pattern is arguably the most used (some times misused) pattern out there.
'Spotlight on GlassFish 4.0.1' is a series of posts that highlights specific enhancements of the upcoming GlassFish 4.0.1 release. It could be a new feature, a fix, a behavior change, a tip, etc.
Before some time I have written a blog post Dependency Injector with Simple Injector. This is a second blog post in same series. In this blog post we are going to learn How we can create a singleton Instance in Simple Injector.
I got a chance to review the "Apache Camel Developer's Cookbook" by Cranton and Korab. Overall I think this is a great book.
Choosing appropriate API security options will help you gain developer trust, increase API adoption, and buildan effective API ecosystem. While APIs are the ‘coolest’ and most effective mechanism to expose business functionalities out towards the outside world and inward to other teams.
JBoss Fuse combines several technologies like core Enterprise Service Bus capabilities (based on Apache Camel, Apache CXF, Apache ActiveMQ), Apache Karaf and Fabric8 in a single integrated distribution
I am not sure why, but in many organisation, there is allot of unnecessary complexity when looking at source code. From Programmers using try/catch blocks all over the show to unnecessary synchronous service calls with multiple threads, causing deadlocks on SQL Server.
This article represents steps required to quickly get up and running with Sonar and keep it handy for your personal Java/.NET/PHP etc related projects
Exposing a REST based endpoint for a Spring Boot application or for that matter a straight Spring MVC application is straightforward.
A proposal for JAX-RS 2.1 has been recently submitted to the JCP, this news was a bit overshadowed by the Java EE 8 Platform submission announcement but it is also important. It is important as JAX-RS is a significant technology of the the Java EE Platform but also relevant outside of the platform.
Apache Camel 2.14 is being released later this month. There is a slight holdup due some Apache infrastructure issue which is being worked on. This blog post is to talk about one of the new functions we have added to this release.
We're living in a more and more distributed world today. Instead of having individual, departmental projects running on hardware, today's systems run at large scale, centralized or even distributed. The needs for monitoring and managing never changed but got far more complex over time.
Make sure you didn't miss anything with this list of the Best of the Week in the Enterprise Integration Zone (Sept 5 to Sept 12). This week's topics include REST API security, SOA principles, REST services with Spring, designing RESTful APIs, and getting started with JHipster.
You have probably used APIs of all sorts when creating applications. It doesn’t matter what the platform is, developers generally have to work with APIs to get any work done because modern applications rely on code that is written by someone else and uses an API for communication.
This is the 3rd post I am writing to explain the use of extension points in WSO2 Identity Server. WSO2 Identity Server has so many such extension points which are easily configurable and arm the server with lot of flexibility.
As a developer, I’m enjoying working on new microservice instances which are effectively greenfield projects with well defined constraints on their interface, but with a flexible internal implementation and therefore a flexible set of tools and frameworks with which we can achieve our goal.
I gave a brief introduction about the Overlord project family yesterday. Today it's time to test-drive a bit. The API Management sub-project released a 1.0.0.Alpha1 two days ago and introduces the first set of features according to the 18-Month roadmap.
I have been learning SimpleInjector for few days and it’s just awesome. I have already written two post about it(see below link) and this post will be third post about it. In this post we are going to learn how we can do Dependency Injection with ASP.NET MVC.
Java 8 was – as always – a release of compromises and backwards-compatibility. A release where the JSR-335 expert group might not have agreed upon scope or feasibility of certain features with much of the audience. See some concrete explanations by Brian Goetz about why.
I have just completed a script that can be used to install a service bus host as a windows service. It is nice to use, when delegating the installs to the support team, this is always done via NServiceBus.Host.exe.
Last week I was tasked with developing a quick prototype that used AngularJS for its client and Spring MVC for its server. My colleague mentioned he was going to use RESThub as his starting point, so I figured I'd use JHipster as mine.
To ensure that your API is ready for success, part of your testing practices should ensure that your API will handle this successful load. You should also be fully ready for surprising growth and popularity of your API!
I have been working on integrating with RabbitMQ to implement the messaging architecture.
I’ve been working on migrating some batch jobs for Podcastpedia.org to Spring Batch. Before, these jobs were developed in my own kind of way, and I thought it was high time to use a more “standardized” approach
Building an API for longevity requires careful thought, careful design, and extensive prototyping to get developer feedback. Without a solid foundation your API is doomed to be short lived, becoming nothing more than a costly experiment to justify building a better API.
