javax.xml.ws.WebServiceException: weblogic.wsee.wsdl.WsdlException: Failed to read wsdl file from url due to -- java.net.ConnectException: Tried all: '1' addresses, but could not connect over HTTP to server: 'sinuxu31', port: '7909'


When the above error occurs, you must check the following.


1) Check that you can view the wsdl URL using a browser

• If the WSDL URL is not accessible then the server hosting the web service is unavailable. 
• Check if you are blocked by any firewall rules.
• You can use the following command in UNIX to get the wsdl file
• wget -O google-wget.txt http://www.google.com 
• cat google-wget.txt

 2) If the WSDL URL is accessible via Browser then check the connectivity to the external server from the server where Web service client is hosted.

• Try ping the external server to check whether able to reach the server in the network
• ping <external_server_host_name></external_server_host_name>
• If the ping is not working, check that hosting server is on the network
• Check if there is any firewall rule set to blocking the network traffic from the calling server
• Telnet to the external server to check whether the Connection to the server is established properly
• telnet <external_server_host_name> <port_number></port_number></external_server_host_name>
• If telnet fails, check whether the port is opened from the calling server to get a connection to the external server
• Do  a nslookup for the external server to check whether the DNS server name mappings
• nslookup 
• > <external_server_host_name>
• If the nslookup fails, check the DNS server name mappings are done properly.
