Hi Alick,
First of all, thank you ! Clarifying some points:
1. I am using directly the IP address in order to not have problems with
DNS, such as:
url[0] ="http://192.168.1.161:8080/webservices/EscalierBeton.jws";;
url[1] ="http://192.168.1.161:8080/webservices/FournitureBetonENT2.jws";;
url[2] ="http://192.168.1.161:8080/webservices/FournitureBois.jws";;
url[3] ="http://192.168.1.161:8080/webservices/FournitureFerENT.jws";;
2. I tried using
java.net.URL site = new URL(url[n]);
URLConnection siteCon = site.openConnection();
instead of using Sockets, I retrieved the content of the page, and
everything works fine.
BufferedReader in = new BufferedReader(new
InputStreamReader(siteCon.getInputStream()));
String inputLine;
while((inputLine = in.readLine())!= null)
System.out.println(inputLine);
in.close();
I think that the problem in when executing SOAP request within AXIS.
How can I test SOAP connections without using AXIS, only to test the network
latency?
Thank you again.
