on Dec 14, 2018MicroProfile 2.1 provides enhancements to the Open Tracing 1.2 feature and how you trace the flow of requests between microservices. This release also has reactive extensions to JAX-RS 2.1 and, on the ops side, Liberty exposes connection pool metrics from its runtime to the /metrics endpoint.
on Dec 5, 2018A preview of what's coming in 18.0.0.4 (async transport layer, connection pooling enhancements, reactive extensions) and a look back at 2018 (reactive client, server sent events, asynchronous methods, URL support, integration with CDI, RestClientBuilderListener for third-party libraries, and more...).
on Nov 23, 2018A quick roundup of some things you can try in the current Open Liberty development builds. Options to skip tracing of JAX-RS requests and using alternative formats of span names in MicroProfile OpenTracing 1.2. Also, try out writing simpler Dockerfiles by packaging your server as a TAR file, and try the support for sharding in Java 11 with JDBC 4.3.
on Nov 9, 2018In development, starting a new log file each time the server restarts is great but, in production, you can now disable this behaviour so that you can retain more history in your logs.
on Nov 5, 2018The Eclipse MicroProfile project allows you to leverage your existing Enterprise Java skills while moving to the cloud-native microservices architecture.
on Oct 18, 2018The Open Liberty team will be at Oracle Code One and EclipseCon Europe! Come meet the team, grab some swag and hang out with us for these two big Java conferences!
on Oct 5, 2018Fault Tolerance provides annotations which allow you to easily apply common fault mitigation strategies to your application but did you know that, since version 1.1, it also exports metrics which allow you to monitor these mitigation strategies?
on Sep 19, 2018Monitor your microservices with metrics from your applications, from Liberty components, and to report on their fault tolerance handling. Plus more for your microservices with Open Liberty 18.0.0.3.
on Sep 19, 2018Separate configuration from your microservices code with MicroProfile Config. Easily and dynamically change your app's configuration by adding and modifying variables in your server config.
on Sep 12, 2018A simple and efficient way of building and pushing layered Docker images of Spring Boot applications using the Boost Maven plugin.
on Aug 16, 2018Get Kevin Sutter's view on how the MicroProfile and Jakarta EE projects could be combined at some point. He describes the progress in establishing each of the two projects, the issues to consider as the projects become more established, and current steps that are being made towards a more integrated future.
on Jul 27, 2018Include only what you need in your runtime. It's as simple as adding dependencies in your Maven or Gradle build.
on Jul 2, 2018Embrace Docker for your Spring Boot applications! Building dual layer Docker images and gain efficiencies for CI/CD teams. This post shows you how.
on Jun 29, 2018Take a more efficient approach to building Docker images for Spring Boot applications when doing iterative development and deployment. The standard approach has some drawbacks so here we look at what they are and how to do it better.
on Jun 29, 2018Full Java EE 8 support, including JAX-RS 2.1 reactive client and server-sent events, CDI event-ordering and asynchonous events, HTTP/2 support in servlets, JSF 2.3, JPA 2.2, JWT cookies (yum!), security improvements,...oh, and you can now deploy Spring Boot applications to Liberty.
on Jun 8, 2018Find out how to build Java microservices with MicroProfile 1.3. Get a quick introduction to microservices, MicroProfile, and an overview of each of the MicroProfile 1.3 technologies, including Config, Metrics, Health Check, JWT, OpenAPI, OpenTracing... Each summary gives links to relevant guides so you can find out more and try out the technologies with your own bare hands.
on May 22, 2018Generate standardised OpenAPI v3 documentation from your RESTful microservices using the new MicroProfile OpenAPI programming model in Liberty. Open Liberty 18.0.0.1 includes an implementation of the MicroProfile OpenAPI 1.0 spec.
on Mar 22, 2018Try out the new JCache-based distributed in-memory session caching in recent development builds of Open Liberty.
on Mar 16, 2018Get distributed tracking of your microservices, a standardised way (through OpenAPI) to describe your RESTful applications, and a type-safe approach to invoking RESTful services over HTTP in Open Liberty 18.0.0.1.
on Jan 31, 2018Learn how to build type-safe REST clients using the new MicroProfile Rest Client APIs in Liberty.
on Jan 12, 2018When you deploy an application to a Liberty server using Open Liberty Tools, it attempts to detect what features your application needs and adds them to the server configuration automatically. Learn how Open Liberty Tools determines what features to add. And how to disable it when necessary.
on Dec 21, 2017And, like a flash, a second release of Open Liberty (17.0.0.4) is upon us! Fancy bringing your own JSF implementation (Mojarra or MyFaces) to Open Liberty? You can now (and benefit from CDI) with the JSF Container 2.2 feature. Also, administrators can now configure concurrency policies for managed executors (Concurrency updates), and get distributed tracing with our implementation of opentracing.io....
on Nov 29, 2017Now that the Open Liberty project is in full swing we are looking for more opportunities to enable developers to use Open Liberty in their own projects. It is very common for developers to create and deploy Spring applications on Open Liberty as a simple web application, but increasingly Spring developers are using Spring Boot as a faster, simpler way...
on Oct 26, 2017Well, this is exciting! Our first proper release of Open Liberty and the Open Liberty Tools! In Open Liberty 17.0.0.3 is a full implementation of MicroProfile 1.2, some Liberty Gradle plugin updates, and some transport security updates. You might have noticed that the download actually went live some time ago but we were so caught up with JavaOne and other...
on Sep 29, 2017Update 2017-10-13: Now with links to JavaOne session videos, where available. Wow, how time has flown! It’s been just two weeks since Open Liberty went live and we totally forgot to mention we’ll be at JavaOne next week. There’ll be a bunch of JavaOne sessions given by Liberty developers (and emeritus developers) throughout the week. If you want to talk...
on Sep 19, 2017I’d like to take this opportunity to welcome you to the Open Liberty project, an open source runtime for Java microservices. In 2012, IBM released WebSphere Liberty, an application server designed for the cloud. It was small, lightweight, and designed with modern application development in mind. It wasn’t perfect, it didn’t have everything people wanted, but it was a great...
