Moving from javax to jakarta namespace

By ActiveMQ, Apache TomEE, Jakarta EE, Java EE, MicroProfile, Open Source, Tomcat, TomEE No Comments

This blog aims at giving some pointers in order to address the challenge related to the switch from `javax` to `jakarta` namespace. This is one of the biggest changes in Java of the latest 20 years. No doubt. The entire ecosystem is impacted. Not only Java EE or Jakarta EE Application servers, but also libraries of any kind (Jackson, CXF, Hibernate, Spring to name a few). For instance, it took Apache TomEE about a year to convert all the source code and dependencies to the new `jakarta` namespace. This blog is written from the user perspective, because the shift from…

Apache TomEE MicroProfile 5.0 certified

By MicroProfile, TomEE One Comment

Last year, we announced Apache TomEE as a certified Jakarta EE 9.1 server (See blog post). The season favors gifts and good news, so I thought I would write this small blog to talk about our journey to being MicroProfile 5.0 certified. A while back, Apache TomEE started implementing MicroProfile. At that time, we were contributing to Apache Geronimo implementations for various specifications: config, openapi, opentracing, metrics, health and fault-tolerance. We had our own JWT implementation with additional integration features than what the MicroProfile JWT specification supports. Back then, we were passing the TCK for the MicroProfile 2.1, released October…

JWT authentication and authorization with Apache ActiveMQ

By ActiveMQ No Comments

Apache ActiveMQ is a well known and very flexible message broker. As such, it fully embraced the AAA model (Authentication, Authorization, Accountability) with built-in plugins.  For example, by default, it comes with Simple Authentication Plugin: it handles user authentication based on the `activemq.xml` defined list of users. Or, as an alternative, you can load users from properties. This is very useful for tests or to quickly bootstrap a project but does not target real-life deployments. JAAS Authentication Plugin: JAAS stands for Java Authentication and Authorization Service and is quite well known in the Java EE space (or Jakarta EE space)….

Apache ActiveMQ Failover with a SQL Database

By ActiveMQ No Comments

ActiveMQ is often a critical component in Enterprise systems, and therefore High Availability (HA) is a “must have” in order to meet production Service Level Agreements (SLA). This blog aims at providing a deployment architecture based on a set of Apache ActiveMQ brokers wired up to a SQL database.  This blog targets Apache ActiveMQ “classic” as opposed to Apache ActiveMQ Artemis. Failover architecture for high availability What are we trying to achieve? A single instance of ActiveMQ can receive and deliver a very high volume of messages. It is very easy to increase performance and handle more messages by simply…

Custom Identity Store with Jakarta Security in TomEE

By Jakarta EE, TomEE No Comments

In the previous post, we saw how to use the built-in ‘tomcat-users.xml’ identity store with Apache TomEE. While this identity store is inherited from Tomcat and integrated into Jakarta Security implementation in TomEE, this is usually good for development or simple deployments, but may appear too simple or restrictive for production environments.  This blog will focus on how to implement your own identity store. TomEE can use LDAP or JDBC identity stores out of the box. We will try them out next time. Let’s say you have your own file store or your own data store like an in-memory data…

Using Tomcat’s `tomcat-users.xml` with Jakarta Security in TomEE

By Jakarta EE, Tomcat, TomEE No Comments

While working on Jakarta EE 10 certification (See announcement Apache Tomee Jakarta EE certified after 10 years, Apache TomEE implemented Jakarta Security specification.  Currently, there is only one implementation used in Glassfish and used by all the other vendors for Jakarta Security. In TomEE, we decided to create an alternative to bring some diversity, and have an Apache implementation. What is Jakarta Security? Jakarta Security defines a standard for creating secure Jakarta EE applications in modern application paradigms. It defines an overarching (end-user targeted) Security API for Jakarta EE Applications. Jakarta Security builds on the lower level Security SPIs defined…

Understanding Jakarta Security with TomEE

By Apache TomEE, Jakarta EE, Tomcat 2 Comments

There are many blogs explaining how to get Jakarta Security on Tomcat using all sorts of libraries and wiring everything manually. So many opportunities to get it wrong, if you are evaluating or currently using Apache TomEE. In TomEE, the good news is that, like JAX-RS, CDI or Bean Validation, Jakarta Security is out of the box ready to be used like Servlet, and CDI for example. This blog is a high-level view so you have the big picture of the technologies and how they interact with each other in the security landscape. The goal is to be able to…

MicroProfile: How it has evolved and where it’s headed?

By Jakarta EE, Java EE, MicroProfile, Open Source No Comments

About a year ago, I wrote a blog post about MicroProfile that explained what it is and why it was created.
