Swagger UI is not working with Jaxrs resteasy

I have integrated swagger using jaxrs resteasy . I have followed all the steps mentioned in the document.

1. Added swagger dependency

2.Added ApiListingResource, SwaggerSerializers and BeanConfig to Application class.

And I'm able to generate the swagger.json.

To display in swagger-ui I added the swagger-ui code in webapp as mentioned in some forums and trying to access dist index.html but every time it says 404 not found.

swagger.json and all the apis' are working except swagger-ui.

Could you please help me and provide solution.

Thanks in advance!
