Create and call custom Java actions — extending Mendix with server-side Java, and invoking those actions from microflows in MDL. Use when logic needs a Java library, an algorithm microflows cannot express, or an integration only available in Java.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

The Java side is next door: - [`reference/writing-java.md`](reference/writing-java.md) — creating the action in Studio Pro, writing the `executeAction` body, the Core API surface you have, and the recurring patterns (HTTP calls, file handling, batch work). …

How to install
mdr add mendixlabs/mxcli/java-actions@sha256:3622c075bb55520aThe line at the top of this page pins the label git:20261029.95fd9c4, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
