Question

How to resolve the 400 The plain HTTP request was sent to HTTPS port issue?

from: empValidation
to: myhost:443/EmpValidation/EmpValidationAPIService
 rules.getRules().forEach(x->{
        final LoadBalanceDefinition lb =  from("jetty:http://0.0.0.0:"+rules.getPort()+"/"+x.getFrom()+"??matchOnUriPrefix=true").log(LoggingLevel.DEBUG, "Processing ${id}").log("Incoming Context Request :"+x.getFrom())
        .loadBalance().roundRobin();
        x.getTo().forEach(z->lb.to("http4://"+z+"?bridgeEndpoint=true&throwExceptionOnFailure=true").log("Outgoing mapping urls :"+z)) ;
      });

if i use "https4" component it's working the above url(empValidation) but it's not working for below url.

Url: myhost:9008/emp-web-service/services/addEmp

Error:

I think if we use default port it's not working, what is solution for the above scenario?

Answer 1

Well, it depends if the endpoint is an http or https endpoint (with server certificate to encrypt the traffic between client and server). No matter under what port number it is published.

• If the endpoint is https enabled, you need to use URIs like https4://hostname...
• If the endpoint is a plain http endpoint, you you need to use URIs like http4://hostname...
