Tutorials

General notes

All tutorials focus on the usage of Jexxa. Therefore, the business logic in these tutorials is without any special meaning. In addition, we assume that you have a basic understanding of:

• Writing Java code and build your programs using maven.

• A general understanding of the used technology stacks such as a messaging system or a database.

• A general understanding of ports and adapters.

• All tutorials run by default without any additional infrastructure services such as JMS or a database.

• In case you want to just run the tutorials, you can use:

  • Docker images provided here. Please note that you need a running ActiveMQ and Postgres database
  • Docker stack starting all tutorials
