Java DID Resolvers is a set of Java libraries for resolving did:web and did:jwk DID documents (Decentralized Identifiers).
Most of us who had to test SOAP or REST web services came across tooling like SoapUI or Postman but didn’t like it. The problem? These tools are UI-centric which often leads to unmaintainable test suites. Kotlin Webtest solves this by enabling a developer/tester to write their SOAP or REST tests in a Kotlin DSL, straight from your favorite IDE.

CQRS Light is a lightweight CQRS library for Micronaut. It allows the use of CQRS without having to introduce a heavyweight framework which might be impossible.
It helps you to encapsulate commands and queries leading to more cohesion and less coupling, which in turns leads to simpler and more maintainable code. There’s a Javascript component for easy front-end integration.
Quarkus CA is an educational project teaching the basics of a Certificate Authority issuing X.509 certificates. At the same time it’s an experiment with the (at the time of writing) brand new Quarkus application framework, a strong new rival of Micronaut.

The Java Message Service (JMS) API is complex, especially when used with distributed transactions (2 phase commits), which are downright unreliable. This is where JMS Gateway comes in: you simply write your JMS messages to a SQL database and JMS Gateway takes care of reliably sending it to the remote message broker. This avoids unreliable 2-phase commits (transactions spanning multiple data sources) since your messaging outbox shares the same database as your application.
MongoMigrate is a Continuous Deployment tool for automating MongoDB schema migrations using Java. It is a perfect fit for microservice frameworks like Spring Boot or Micronaut.
