Hi Markus,

is the server using a self-signed certificate? If not, i.e. it's just good ol' https with a cert issued by a trusted CA, you should be fine using the build in java http client with https, something like…

-----------------------

public static String post( final String url, final String requestBody ) throws IOException, InterruptedException {
// Create a client (the client can be reused so for performance sensitive code, I wouldn't do this within the method)
final HttpClient client = HttpClient
.newBuilder()
.build();

// Construct a request to submit
final HttpRequest request = HttpRequest
.newBuilder()
.uri( URI.create( url ) )
.POST( BodyPublishers.ofString( requestBody, StandardCharsets.UTF_8 ) )
.build();

// Submit the request
final HttpResponse<String> response = client.send( request, HttpResponse.BodyHandlers.ofString( StandardCharsets.UTF_8 ) );
return response.body();
}

-----------------------
