Hi I have a project to combine spring-boot and react. I’m using openvidu-js-java to backend and openvidu-insecure-react to frontend. I tried to get a token from backend then sent it to frontend, frontend had token but it didn’t display the camera but my laptop noticed that it displayed camera. How can I fix it? In my code. I choose the attribute is “publisher1” and logged Thank for answers ![image](https://global.discourse-cdn.com/free1/uploads/openvidu/original/2X/6/67a439b7b4acf179f801dcd54f1fdae11f3d3634.png) ---

Spring-boot example you are using hasn’t CORS enabled. Configure CORS in SpringBoot example following this tutorial: > **[CORS with Spring | Baeldung](https://www.baeldung.com/spring-cors)** > > Simple config for CORS with the built-in support in Spring MVC. Regards ---

I have a question: I only sent token for the frontend then does it work? Do I need to add connectionId, id, type,… such as data when I only used insecure-react? ---

You only need the token, and call to the `connect` method of the `Session` object: [Session | OpenVidu Browser - v2.18.0](https://docs.openvidu.io/en/2.18.0/api/openvidu-browser/classes/session.html#connect) ---

I tried to do that but it still doesn’t work, when I check in frontend (unsecure-js) I realize it doesn’t setState at here so it doesn’t display screen ![vidu02](https://global.discourse-cdn.com/free1/uploads/openvidu/original/2X/3/306e4566d8a27f36c99207c3e3269ed88231579c.png) ---

Take a look to react sample. It should work. Just replace token generation from frontend to backend. Let the rest of the code exactly the same.
