Hi Shashank,

Thanks for the error stacktrace, can you try the following:
- Download again latest lite agent and configure lite agent as per docs:

http://litedocs.appdynamics.com/display/ADLite/Oracle+WebLogic

- if the issue still persists, please attach the following logs or send logs to akumar@appdynamics.com to debug further:

- <lite-agent_install_dir>/logs
- weblogic server startup console logs and server logs with agent stack trace

- weblogic version and jdk version used by the weblogic domain used in your test environment

Thanks,

Arun
