Project: Apache Axis 2.0 (Axis2)
Type: Bug
Components: client-api
Versions: 1.0
Environment: Windows XP SP2, Java J2SE 1.5.0_03, Axis 2 SNAPSHOT Jun 08, 2006
Reporter: Michele Mazzucco
I'm trying to send a message from a web service A to a web service B, but I get
this exception:
ERROR

The chunk of code generating the above exception is:
EndpointReference targetEPR = new EndpointReference(target);
Options options = new Options();
options.setTo(targetEPR);
options.setAction("urn:echo");
options.setTransportInProtocol(Constants.TRANSPORT_HTTP);
options.setUseSeparateListener(true);
ServiceClient sender = new ServiceClient();
sender.engageModule(new QName(Constants.MODULE_ADDRESSING));
sender.setOptions(options);
try {
sender.sendRobust(r.request);
} catch (Exception e) {
StringWriter sw = new StringWriter();
PrintWriter pw = new PrintWriter(sw);
e.printStackTrace(pw);
log.error(sw.getBuffer().toString());
pw.close();
}
Please note that this code works if a sendReceiveNonBlocking() call is
used instead of sendRobust().
