I have an AIR application that uses remote objects to communicate with the server. It works perfectly when the application connects to my localhost server. But as soon as I change the url to point to a remote test server, I get the following error:
fault.message: faultCode:Client.Error.MessageSend faultString:'Send failed'
faultDetail:'Channel.Connect.Failed error NetConnection.Call.Failed: HTTP:
Failed: url: 'http://remoteserver:80/app/messagebroker/amf''
fault.name: Error
fault.faultcode: Client.Error.MessageSend
fault.faultstring: Send failed
fault.faultdetail: Channel.Connect.Failed error NetConnection.Call.Failed: HTTP:
Failed: url: 'http://remoteserver:80/app/messagebroker/amf'
What might cause this error? My local server is a glassfish 3.1, the remote one uses apache for load balancing in front of a glassfish.
When I navigate in the browser to the url of amf channel, it displays a blank page (which is fine).
I have also noticed that when I use tcp/ip monitor from eclipse, (I change the url to point to some port on localhost; tcp/ip monitor forwards the request to the remote server), the application works fine, no error occurs. Still, it appends a jsessionid to the url.
How can I resolve this issue?

I've deployed my Java web application to a AWS server, but I get an 502 proxy error like this when making a get request:
The proxy server received an invalid response from an upstream server.
The proxy server could not handle the request GET /product.
Reason: Error reading from remote server
The database connection works fine if the application is deployed locally with an online database.

My company’s web application is using GWT both for front-end and back-end and we’d like to remove GWT from the project. Our current objective would be to make a new login page in Angular2 using the existing GWT back-end.
The main problem we encounter at the moment is that all the requests coming from outside the current GWT front-end seem to be intercepted/blocked and don’t return anything. I’m currently using Postman to make GET requests from the server.
Here is the URL I’m calling : http://localhost:9997/RestServer/api/users/1.
Postman’s response:
« Could not get any response
There was an error connecting to http://localhost:9997/RestServer/api/users/1. »
GWT Development Mode’s console returns an error:
[TRACE] Connection received from 127.0.0.1:60296
[ERROR] Unrecognized command for client; closing connection
com.google.gwt.dev.shell.BrowserChannelException: Invalid message type 71

Have you got any idea why my requests are intercepted? Why I can't even receive a http response?
If you need more informations to answer just ask for it.
Port 9997 in the old dev mode is not an HTTP server. This is the port on which the legacy browser plugin (unsupported in modern FF and Chrome due to breaking changes in those browsers) would connect to run Java code and enable remote debugging, hotswapping, etc.
Instead, you need to connect to the HTTP port, which is 8888 or 8080 or something like that.
I followed this tutorial to build a spring websocket application. I've kept each file as it is but I'm neither using maven nor gradle. I run the index.html file on the tomcat server. When I click connect I get:
Opening Web Socket... GET http://localhost:8080/hello/info 404 (Not
Found) Whoops! Lost connection to undefined
in my Chrome's Developer window.
Why is this happening?
link may help. here I have given whole example.
for this you will require stomp.js, sockjs on your client side
and spring-websocket & spring-messaging 4.2.6.RELEASE jar in your server side,
I have set up WSO2API manager on EC2 server and using nginx for serving requests.
If I access https://example.com/carbon with my domain ssl, it works fine. and I got the verified indication on browser URL.
But when i access https://example.com:9443/store/forum it gives me SSL error at the top. When I investigate the issue i found "Common name as localhost"
How to solve this issues?
I downloaded Tomcat Deployer
so i could deploy remotely to my tomcat server, when insert all the correct details it ask for such as:
Manager URL
Username/Password
URL of sync App
when i try to deploy i keep getting this error:
Failed to deploy: com.caucho.hessian.client.HessianRuntimeException: java.net.ConnectException: Connection refused: connect
Projecct [HFJSe] deploy completed.
And nothing is deployed.
If there anything i need to do on my Tomcat server?
The error states that the target machine is refusing the connection, so you'll need to check the following information:
The URL is correct (I know you've stated it, but the URL should be in the format of http://{host}:{port}/TomcatHelper (from what I understand in the documentation)
That if there is a configuation file, that the port is configured appropriately
The target server has that port open to accepting connections
Your username and password is correct
If your "remote" server is on the same local machine, use your loopback address (i.e. localhost
