If you create components (sequences, endpoints, etc.) of the ESB externally, you can save them as CAR file and upload this Application into a running Carbon instance using the management console.
Follow the instructions below to upload an application in WSO2 ESB.
1. Sign in. Enter your user name and password to log on to the ESB Management Console.
2. From the left navigation menu, under the "Applications," select "Add."
3. Select your CAR file by browsing the file system. Click on the "Browse" button.
4. Select a CAR file and click on the "Upload" button.
5. After you upload the CAR file, the "WSO2 Carbon" window appears. Click "OK" and refresh the page to see the status of a new Application.
6. Your CAR file is dropped to the ESB_HOME/repository/deployment/server/carbonapps directory.
Note
As an alternate to uploading the cApp using the management console, you can copy your CAR archive into ESB_HOME/repository/deployment/server/carbonapps folder manually and it will be hot deployed.
