How the iDempiere micro microservices work

The iDempiere micro microservices are standalone Java 1.8 applications packaged as self-contained executable JARs.

Runtime Prerequisities

To run iDempiere micro microservices Java Runtime Environment (JRE) 8 or higher e.g. OpenJDK 8 is required.

Database

The iDempiere micro microservices use the same database as iDempiere. Since not only the same object-relational mapping engine is used, but also the same iDempiere business logic classes are shared between these two project, the data are stored exactly in the same way making them directly usable from the iDempiere User Interface.

The Database JDBC URL is set in the Database.url configuration parameter (e.g. in DATABASE_URL environment variable) for example like jdbc:postgresql://localhost:5433/idempiere. The user name and password to connect to the iDempiere database are set in the Database.username and Database.password parameters following the iDempiere approach of a technical user to be used for all the database calls.

Web API

Each of the iDempiere micro microservices opens an HTTP endpoint allowing REST and GraphQL calls to be made.
