Hi,

I am working on a application that tries to send out a message to server . but when the system tries to post to the server it gets the following exception


java.net.ConnectException: Connection refused
at java.net.PlainSocketImpl.socketConnect(Native Method)
at java.net.PlainSocketImpl.doConnect(PlainSocketImpl.java:333)

at sun.net.www.protocol.http.HttpURLConnection.connect(HttpURLConnection.java:694)
at sun.net.www.protocol.http.HttpURLConnection.getOutputStream(HttpURLConnection.java:861)




I found that the excption is being triggerd from my code in a line where an attempt to get an outputstream is made with the httpurlconnection object.

Can somebody tell me what are the probable causes of such an exception?

The most common causes are a firewall between your server and client or the server is not listening. Can you open the same URL with a browser?

Can you ping the server?
