Create a new directory named samplej2ee.ear in the applications directory of your WebLogic domain. Extract the EAR file (without copying the EAR file) to this new directory:

applications> mkdir samplej2ee.ear
applications> cd samplej2ee.ear
samplej2ee.ear> jar -xvf /path/to/samplej2ee.ear

Deploy the application by using the admin console (Deployments -> Applications). If you have autodeploy on, you may see the application already deployed. If you do not, select Deploy a new Application. Select samplej2ee.ear and deploy to the proper server targets. If you have installed the application correctly, you should find CarHome listed in the JNDI tree under myserver->samples->j2ee->ejb .
