You can enable App and API Protection for Java services with the following setup options:

If your Java service already has APM tracing set up and running, then skip to service configuration
If your Java service doesn't have APM tracing set up, you can easily enable App and API Protection with Datadog's Automatic Installation
Otherwise, keep reading the following manual setup instructions

Overview

App and API Protection works by leveraging the Datadog Java library to monitor and secure your Java service. The library integrates seamlessly with your existing application without requiring code changes.

For detailed compatibility information, including supported Java versions, frameworks, and deployment environments, see Java Compatibility Requirements.

This guide explains how to set up App and API Protection (AAP) for Java applications. The setup involves:

Installing the Datadog Agent
Enabling App and API Protection monitoring
Running your Java application with the Datadog Agent
Verifying the setup

Prerequisites

Kubernetes cluster
Java application containerized with Docker
kubectl configured to access your cluster
Helm (recommended for Agent installation)
Your Datadog API key
Datadog Java tracing library (see version requirements here)

1. Installing the Datadog Agent

Install the Datadog Agent by following the setup instructions for Kubernetes.

2. Enabling App and API Protection monitoring

Automatically enabling App and API Protection through Remote Configuration

APM Tracing cannot be disabled for the time being with remote config.

You can enable remote configuration on your services dashboard. Simply check the box for the service you want to enable App and API Protection for under "Activate on your APM services".

Manually enabling App and API Protection monitoring

Download the latest version of the Datadog Java library using an init container:

apiVersion: apps/v1
kind: Deployment
metadata:
  name: your-java-app
spec:
  template:
    spec:
      initContainers:
      - name: download-agent
        image: busybox
        command: ['sh', '-c', 'wget -O /shared/dd-java-agent.jar https://dtdg.co/latest-java-tracer']
        volumeMounts:
        - name: agent-volume
          mountPath: /shared
      volumes:
      - name: agent-volume
        emptyDir: {}

APM Tracing Enabled

Start your Java application with the Datadog agent and App and API Protection enabled using command-line arguments:

apiVersion: apps/v1
kind: Deployment
metadata:
  name: your-java-app
spec:
  template:
    spec:
      containers:
      - name: your-java-app
        image: your-java-app-image
        volumeMounts:
        - name: agent-volume
          mountPath: /dd-java-agent.jar
          subPath: dd-java-agent.jar
        command: ["java"]
        args: ["-javaagent:/dd-java-agent.jar", "-Ddd.appsec.enabled=true", "-Ddd.service=<MY_SERVICE>", "-Ddd.env=<MY_ENV>", "-jar", "/app.jar"]

Start your Java application with App and API Protection enabled using environment variables:

apiVersion: apps/v1
kind: Deployment
metadata:
  name: your-java-app
spec:
  template:
    spec:
      containers:
      - name: your-java-app
        image: your-java-app-image
        volumeMounts:
        - name: agent-volume
          mountPath: /dd-java-agent.jar
          subPath: dd-java-agent.jar
        env:
        - name: DD_APPSEC_ENABLED
          value: "true"
        - name: DD_SERVICE
          value: "<MY_SERVICE>"
        - name: DD_ENV
          value: "<MY_ENV>"
        command: ["java"]
        args: ["-javaagent:/dd-java-agent.jar", "-jar", "/app.jar"]

APM Tracing Disabled

To disable APM tracing while keeping App and API Protection enabled, you must set the APM tracing variable to false.

Start your Java application with the Datadog agent and App and API Protection enabled using command-line arguments:

apiVersion: apps/v1
kind: Deployment
metadata:
  name: your-java-app
spec:
  template:
    spec:
      containers:
      - name: your-java-app
        image: your-java-app-image
        volumeMounts:
        - name: agent-volume
          mountPath: /dd-java-agent.jar
          subPath: dd-java-agent.jar
        command: ["java"]
        args: ["-javaagent:/dd-java-agent.jar", "-Ddd.appsec.enabled=true", "-Ddd.apm.tracing.enabled=false", "-Ddd.service=<MY_SERVICE>", "-Ddd.env=<MY_ENV>", "-jar", "/app.jar"]

Start your Java application with App and API Protection enabled using environment variables:

apiVersion: apps/v1
kind: Deployment
metadata:
  name: your-java-app
spec:
  template:
    spec:
      containers:
      - name: your-java-app
        image: your-java-app-image
        volumeMounts:
        - name: agent-volume
          mountPath: /dd-java-agent.jar
          subPath: dd-java-agent.jar
        env:
        - name: DD_APPSEC_ENABLED
          value: "true"
        - name: DD_APM_TRACING_ENABLED
          value: "false"
        - name: DD_SERVICE
          value: "<MY_SERVICE>"
        - name: DD_ENV
          value: "<MY_ENV>"
        command: ["java"]
        args: ["-javaagent:/dd-java-agent.jar", "-jar", "/app.jar"]
