java-actions skillA

java-actions is agent-read markdown (skill) from mendixlabs/mxcli: 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..

Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.

What the file says

# Mendix Java Actions Skill

This skill provides comprehensive guidance for creating and using custom Java actions in Mendix projects.

## Reference files

`SKILL.md` covers declaring a Java action in MDL and calling it from a microflow —
the parts that touch the model. 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).
- [`reference/best-practices.md`](reference/best-practices.md) — error handling,
  transactions and rollback, logging, threading, security, and performance. Read
  it before shipping a Java action that touches data or an external system.

## When to Use This Skill

Use this skill when:
- You need to extend Mendix with custom Java logic
- Building integrations with external Java libraries
- Implementing complex algorithms not feasible in microflows
- Calling Java actions from MDL microflows
- Debugging Java action calls

## Overview

Java actions allow you to extend Mendix with custom Java code. The workflow is:

How to install

Latest version
mdr add mendixlabs/mxcli/java-actions@git:20260825.190245c
Exact content
mdr add mendixlabs/mxcli/java-actions@sha256:b783e0810cb4cbc0

Pin to a label to follow the author's releases, or to a sha256 to freeze the exact bytes forever. Either way the resolved hash is written to mdr.lock, and mdr install reproduces it on any machine.
