WSIFException

[Sachin Mittal]

Hi            My application  has to call a  .Net webservice . It is working fine       when  I called through a client(using dynamic WSIF) on my machine(Windows)  that  is not behind the firewall       But when I put it on the Unix box that  is behind the firewall I got the exception(Unable to find an available port)           It seems a firewall issue but I am not sure.       Earlier I was unable to  invoke the URL  on which webservice is running, but later they(firewall)       open a port 443 for outbound request to invoke this URL which is working fine now       But still I am getting follwing exception       org.apache.wsif.WSIFException: Port 'CWESPSoap' is not available and  no alternative can be found         Here  is the code also                             WSIFService service =  factory.getService(wsdlLocation,   null,   null, portNameSpace, servicePort);                             java.util.Iterator it = service.getAvailablePortNames();                        while (it.hasNext()) {                          System.out.println("port");                           System.out.println(it.next());                        }                     // get the port                   WSIFPort port = service.getPort("CWESPSoap");    at // 1                   got exception as mention above . Also tried using default port  then exception message is Unable to find an available port               I am woking through ssh on unix box   Please help me .   Regards & Thanks Sachin
