Enabling Swagger UI on OpenApi

Hello,

Please, I’m new to Javalin and I will love to expose my API using SwaggerUI, hosted on my embedded jetty server. Below is my configuration:

return new OpenApiOptions(applicationInfo)
                .path("/swagger-json")
                .activateAnnotationScanningFor("my.package")
                .swagger(new SwaggerOptions("/swagger").title("My Swagger Documentation"))
                .reDoc(new ReDocOptions("/redoc").title("My ReDoc Documentation")) ;

But I’m getting a blank page when I visit ~/swagger and the following on my console.

http://localhost:7001/webjars/swagger-ui/3.23.8/swagger-ui.css net::ERR_ABORTED 404 (Not Found)
swagger:27 GET http://localhost:7001/webjars/swagger-ui/3.23.8/swagger-ui-bundle.js net::ERR_ABORTED 404 (Not Found)
swagger:28 GET http://localhost:7001/webjars/swagger-ui/3.23.8/swagger-ui-standalone-preset.js net::ERR_ABORTED 404 (Not Found)
swagger:31 Uncaught ReferenceError: SwaggerUIBundle is not defined
    at window.onload (swagger:31)

Please note that I enabled Webjars ...config.enableWebjars();... but still not working 😦

@tipsy I am having the same problem but it is because the server is behind a reverse proxy. How can I set a prefix to let swagger ui know where to read the files ? like localhost:8000/webjars -> localhost:8000/myprefix/webjars

Oh Yes, I was using a different plugin. Thanks, @tipsy. It’s fine now.
