You can try to access the default database in restfulws: ‘http://localhost:9090/denodo-restfulws/admin’ and the webpage will prompt you for credentials. If the webpage is not accessible,
I would make sure the Denodo internal Web Container is started.
For more details, you can refer to a similar community questions:
* [Denodo Express Restful Web Services](https://community.denodo.com/answers/question/details?questionId=90670000000k9koAAA&title=Denodo+Express+Restful+Web+Services)
* [Web container status: OFF](https://community.denodo.com/answers/question/details?questionId=90670000000CcrkAAC)
Hope this helps!
