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. Click the "Main" button to access the "Manage" menu.
3. From the left navigation menu, under the "Applications," select "Add."
4. Select your CAR file by browsing the file system. Click on the "Browse" button.
5. Select a CAR file and click on the "Upload" button.
6. 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.
7. The CAR files you deploy this way are dropped to the <PRODUCT_HOME>/repository/carbonapps/{tenant-directory}. As an alternative to uploading the cApp using the management console, you can copy the CAR archive into <PRODUCT_HOME>/repository/carbonapps/{tenant-directory} manually and it will be deployed.
8. If successfully deployed, the cApp should be listed on the "Applications List" window.
Note
If the Carbon application does not have artifacts which are applicable to the particular product you are using, nothing will be listed on this window.
