MicroProfile Fault Tolerance Annotations

By Eclipse Foundation, MicroProfile, Open Source No Comments

In our last article about Microprofile Fault Tolerance we explained the motivation for this project and the need to provide a few design patterns under the microservice friendly Microprofile spec, namely: Bulkhead – isolate failures in part of the system. Circuit breaker – offer a way to fail fast. Retry – define criteria on when to retry. Fallback – provide an alternative solution for a failed execution. We also presented some of the libraries that implement this Microprofile specification, including the Geronimo Safegard library, the one used on TomEE 7.1. Lets now dive a bit deeper into the spec and…

TomEE: Tutorial on MicroProfile JWT

By Apache TomEE, MicroProfile 4 Comments
Last week we published the post, "MicroProfile JWT" by @JLouisMonteiro that covers the basics, standards, pros, and cons involved in implementing stateless security with Microprofile JWT. In this post, we are going to deep dive into JWT role-based access control on Apache TomEE. Since the release of TomEE 7.1, we now have a JWT specification implementation defined using Microprofile version 1.2. The specification is available in the official release. Marking a JAX-RS Application as Requiring MP-JWT RBAC For this, you need to add the annotation @LoginConfig to your existing javax.ws.rs.core.Application subclass.

MicroProfile JSON Web Token (JWT)

By MicroProfile, Open Source No Comments

In the post, “What is Eclipse MicroProfile”, we explained what Eclipse MicroProfile is and why it’s important. MicroProfile is made up of several specifications. In this post, I’ll explain the JSON Web Tokens (JWT), the MicroProfile JWT specification, and how it can be used to implement stateless security in microservices. I’ll also talk about the extensibility and flexibility of MicroProfile with claims. Tomitribe has been helping companies implement REST services for years and one of the most common problems our clients have is deciding how to implement authentication and authorization. The development of MicroProfile and its use of JWT is…

Tomitribe at EclipseCon France

By Community, MicroProfile, Open Source No Comments

I had the privilege of being invited to speak at EclipseCon France (June 13th & 14th) about Microprofile, microservices, and JWT.  The conference took place in Toulouse and being from France I have been there a couple of times, but never took the time to enjoy it. The architecture is beautiful, the city clean, and the people nice. Don’t know if it was because it was the beginning of summer or not, but I found the city very active and alive in the evenings. The conference was held at the convention center downtown. The venue is large and well organized. There were…
