Managing global (XA) transactions on AWS with WebSphere Liberty

A <a href="https://en.wikipedia.org/wiki/Transaction_processing">transaction</a> is an <em>atomic</em> unit of work in which multiple updates (e.g. to a database) must be completed within the transaction or, if there are problems, none of the updates are made at all (also known as <em>two-phase commit</em>). The purpose of transactions is to avoid situations where only part of an update is made. This article demonstrates a WebSphere Liberty application that processes global (XA) transactions across multiple resources and how Liberty automatically recovers the XA transaction during a simulated server failure in a cloud environment.

HTTP session management with WebSphere Liberty, eXtreme Scale, and Amazon Web Services

HTTP sessions are used to manage state. A common example is the contents of a shopping cart. A user might make multiple visits to a site over a period of hours or days, all the time putting more items in their cart. This article looks at how to manage this data across multiple HTTP sessions on WebSphere Liberty in AWS.

Liberty in Docker on a Raspberry Pi

It seems like everyone is looking at what they should be <em>containerising</em> (yes, that's a word!) in <a href="https://www.docker.com/">Docker</a> to help improve their development, test, and production pipelines. With the recent <a href="/wasdev/docs/deploying-applications-docker-1-12-liberty/">release of Docker 1.12</a>, it's now easy to deploy Docker on a <a href="https://www.raspberrypi.org/">Raspberry Pi</a>. As Liberty was <a href="https://twitter.com/WASdevnet/status/763744610627776512">the first application server to be shown running on a Raspberry Pi</a> we're always looking at how we can take advantage of the awesome little computers. So I set off on a mission to see how easy it is to get a Raspberry Pi-compatible Docker image of Liberty, and then to see how many instances of that image I can run on a single Raspberry Pi.

Get started with CDI interceptors in WebSphere Liberty (Part 2)

Interceptors are classes that intercept method invocation or lifecycle events of a target class to perform some form of pre- or post-processing that is usually separate from the business logic, such as logging or auditing. The first article in this series showed how to associate an interceptor with a CDI bean using interceptor bindings. This second article shows how you can associate multiple CDI interceptors with a bean, allowing each interceptor to be dedicated to performing a specific task. This will create a chain of interceptors, which will be executed in the order defined in the <code>beans.xml</code> or using the <code>Priority</code> annotation.

Traditional WebSphere or Liberty: how to choose?

WebSphere Liberty has now 'grown-up' to provide the full Java EE 7 platform. Combining that API set with operational capabilities that have been rapidly expanded over the past three years, Liberty is now a great deployment choice for many Java applications. WAS traditional remains fully strategic, however, and will evolve to the Java EE 7 standards itself in time, so how do you choose between the two?

Application deployment in Liberty

A common requirement whilst developing an application is to run your application in an expanded format. The easiest and quickest way is to put that application into the `dropins` directory in the server's configuration directory. This automatically deploys your application to your Liberty server. Alternatively, you can put the application in the `apps` directory in the server's configuration directory and add an entry to the server's `server.xml`. This means you have more control over certain aspects like security bindings or classloader delegation. By default, Liberty looks in both directories for applications.
