Thanks for posting the question on the Community.
Java agent installation is documented in this link: https://docs.appdynamics.com/display/PRO45/Install+the+Java+Agent
As the overview of installation process,
Download and unzip Java agent
Edit your controller information in controller-info.xml
Add -javaagent JVM option to your application startup script
To check its working correctly, you can see “Started AppDynamics Java Agent Successfully” in log file of the agent. Also you can check by accessing your web application, and see transaction in controller UI.
Let me know if this helped you.
