This is a question for the internal workings. How is the swagger-ui server (from my understanding a node.js web server) able to listen on the same port as the REST server? I'm using python quart for the REST server.
From my understanding, 2 processes cannot bind to the same server. So how does the node.js server bind to the same port my quart server is bound to?

I have read up on web sockets providing full duplex connections over TCP which can be used in scenarios where long polling was used to get live updates to client from server. Now I have a Tomcat based application which serves multiple REST based web service response, and I want couple of API's to be implemented using web sockets say to render dashboard with latest data where multiple users are working on them concurrently, is that possible ? My concern here was even if the connection was upgraded to TCP from HTTP wouldn't web socket require a separate port to run than the default Tomcat port 8080. In that case should I house the Web Socket based endpoints separate to the Tomcat based application already running. Please do correct me if any of the above is wrong.
A couple of month ago, I wrote a small Spring Boot webapp with embedded Tomcat that provides both, REST endpoints and websocket support, and both via the same port. So, yes that works... if you wanna sneak a peek: https://github.com/tommybrettschneider/pinterest-boot
Besides that, this post should also clarify things:
Shall I use WebSocket on ports other than 80?
I am trying to validate server-client connectivity. I am running the client in one system and server in other system. When i manually running the Wiremock server in client system, i am able to see the responses from Server. My question here is "How to run the Wiremock Server in Server system via client System".
I have built a working IBM api connect service (loopback) that provides local mySQL data to/from an angular website. I now want to move this service to an Ubuntu web server (appache) so that I can open up the website to external traffic. I have moved installed api connect onto the server and moved the project files across.
But I don't understand how to run the project so that it is available externally. When I run API connect the api is available on a local port address: Web server listening at: http://127.0.0.1:9000.
But in my webpage (angularjs) I can't call this as it tries to connect on the client machine, not server.
Has anyone done this before and if so, can you offer any advice?
You should configure your Apache as a reverse proxy, so that it forwards requests from your public ip address at port 80 (or 443 if you want SSL) to localhost:9000. See https://httpd.apache.org/docs/2.4/howto/reverse_proxy.html or https://www.nginx.com/resources/admin-guide/reverse-proxy/ if you'd like to try out Nginx.
Today I'm hosting a Laravel v4 web application on a MacMini. Why a Mac? Because I created the application logic in Objective-C (leveraging my experience with iOS dev). Whether or not this was the right choice isn't the point of the question.
What I'm interested in knowing is how can I separate my web and application server. For instance, if I put my web server on Linode (or whatever) how do I go about communicating back and forth between the web server and the application server? Is there some sort of resource I can look to to understand how to do this?
Assumptions
Here's some assumptions I'm making:
I'm guessing Laravel and the Objetive-C Application are part of the same "system" and so I'm just gonna treat this as if you need a web server to send requests to a PHP application.
The Linode server will be a web server which sends request to the PHP application (Laravel)
Hosting PHP Applications
There are three moving parts:
The web server (Apache, Nginx)
The application gateway (PHP-FPM)
The application
The gateway and the code must live on the same computer/server. The web server can live on a separate computer/server.
This means you'll need your Macintosh to run PHP-FPM, which can then listen for remote connects and send them to the PHP application.
Macintosh
Install php-fpm on your mac. Make sure it can listen for remote network connections. This is usually done in the www.conf file in the listen directory, you can listen for connections on the remote network interface (whatever IP address the computer is assigned).
Linode
Install Nginx or Apache and have it proxy FastCGI requests off to your macintosh server at the macintosh's IP address (the one you set up to listen to addresses in the step above).
Firewalls
You may need to ensure the firewalls at both ends allow incoming/outgoing connects on the networks being used to communicate to eachother.
in eclipse, i have a weblogic server running, and a j2ee application deployed to it.
the application is serving on port 7001.
i want to hook the monitor up to the application, i do not know what ports to use.
i think i know what to put in for the Host Name (localhost:7001), but not sure of what to use for type and Local Port. in the proeferences, what is meant by Local Port.
does it matter if i start the monitor before or after the application is running?
my goal is the watch the traffic as i login, from my local machine via a browser, and surf to other parts of the application.
thanks for any help
if your original url for webservice is say http://abc.xyz:5674/ws/wsdl:linkaction
then do these settings for tcp/ip monitor:
local monitoring port:8888
hostname:abc.xyz
port:5674
type:http
Start it
And change the webservice url to "http://localhost:8888/ws/wsdl:linkaction"
Run your client.java as java application
so your request will go through tcp/ip proxy and you can see the soap messages.
The monitor basically acts as a proxy. The local monitoring port is the port you will send requests to the monitor on. It can be any free port (7002, for example).
The host name, port, and type describe what you want the monitor to proxy to. In your case, it would be localhost, 7001, and HTTP.
Then, you would use your browser to access localhost:7002, and the proxied requests and responses would be displayed in the monitor.
Normal SOAP envelope flows
1. Client ----> SOAP envelope ----> Server:9999
Server:9999 ----> SOAP envelope ---> Client
To intercept SOAP envelope, you can host another server (“TcpMonitorServer”) in between client and server, see new flows :
Client ----> SOAP envelope ----> TcpMonitorServer:8888
TcpMonitorServer:8888 --> SOAP envelope ---> Server:9999
Server:9999 ----> SOAP envelope ---> TcpMonitorServer:8888
TcpMonitorServer:8888 ----> SOAP envelope ---> Client
