# Configure the Java agent

The standard installation for all agents uses this order of precedence.

Configure the Java agent using:

You may need to configure your application’s Java environment to work effectively with the agent if your system uses:

• Standalone applications: If your JVM server hosts a single application you should specify the name using agent.java.standalone_app_name. Certain features like route coverage and build-based views require this.

• Multi-tenant application configuration: If your JVM web server hosts multiple applications during a deployment, you can distinguish applications from each other and then apply individual configuration options.

### Important

In some cases, you may wish to configure the agent to use a single application name but do not wish to treat application server code as belonging to the application. In this case, use application.name instead. Certain features like route coverage and build-based views do not work with application.name as they do with agent.java.standalone_app_name.

• TLS certificates

• Java 9 Modules

• Java 2 Security

• Other tools and technologies: The Contrast Java agent, can also be configured and run in conjunction with several third-party tools, plugins and integrations. Consult the remote product documentation for information about how other products work.

## Java system properties

Substitute <YourContrastJarPath> with the path to your Contrast JAR, and use these commands to learn more about system properties:

• To generate a list of general properties using the Contrast agent JAR, use:

 java -jar <YourContrastJarPath> properties
• Use command line with tools to search for commands. For example, these commands display a list of proxy-related properties:

Using the built-in filter:

java -jar <YourContrastJarPath> properties --filter=proxy
