OL Hub Release Notes v2.4.0

Release Date: 13 November 2023

PostgreSQL DB Connector

A new connector, postgres-db, is now available to connect to PostgreSQL databases. The user must connect via JDBC and specify an executable path to a procedure or function. There is also an overload option that determines the stored procedure to fetch when multiple procedures have the same name.

SAP-JCo-Server Generator

A new generator is now available in the CLI: sap-jco-server. This enables deploying an OL Hub project as an SAP JCo server in a Java runtime environment. The result is a low-code Java project based on OL Hub flows that match the customer’s business logic. Each method in the OL project contract represents the flow of a request from SAP, where the flow output is the response returned to SAP.

Additional options when selecting Java generator

If a Java generator is selected, additional configurable options are available, such as Template, Cache and Agent.

New node added in flow map

A new node, Error, enables specifying output error codes.
