Error When Deploying a CAR App to WSO2 ESB


Issue

When deploying a CAR File to WSO2 ESB you might come accross the following exception. In my case I came accross the following issue when uploading a secure CAR app.



ERROR - ProxyServiceDeployer ProxyService Deployment from the file : /home/yasassri/Support/MYSUP/wso2esb-4.9.0/tmp/carbonapps/-1234/1455007998187Sec_CarApp_1.0.0.car/SimpleProxy_1.0.0/SimpleProxy-1.0.0.xml : Failed.

Possible Reason

 Possible reason for this issue is that by default when you create a registry resource in Dev studio the default server role is set as governance registry. So when you try to upload a such CAR to ESB you might see the above issue.

Remedy

 In order to oversome this issue you can change the server profile of the project to ESBProject. To do this follow the instructions below.

1. Create a composite application project (Whic is needed to create a CAR app) and select export as a composite application project option. This will bring up CAR app creation wizard.



2. Now click next and you will see the project selection page. In this expand the Registry resource project created for ESB and set the Server role. Refer the following





After doing the above hopefully it will solve the issue. please drop a comment if you have any queries.
