У меня есть веб-сервис Axis2 под названием DownloadServer, который вызывает другой веб-сервис Axis2 под названием Publisher. Они развернуты на одном сервере. Вот код для двух веб-сервисов.
В классе Publisher.java:
public String getFileServers(){
return "http://localhost:8080/axis2/services/FileServer1?wsdl http://localhost:8080/axis2/services/FileServer2?wsdl";
}
В классе DownloadServer.java:
public synchronized String getBandwidth(String title) {
try {
// Call Publisher service to get addresses of File Servers
RPCServiceClient serviceClient = new RPCServiceClient();
Options options = serviceClient.getOptions();
EndpointReference targetEPR = new EndpointReference(
"http://localhost:8080/axis2/services/Publisher?wsdl");
options.setProperty(HTTPConstants.AUTO_RELEASE_CONNECTION,
org.apache.axis2.Constants.VALUE_TRUE);
options.setTo(targetEPR);
QName methodName = new QName("http://ws.apache.org/axis2",
"getFileServers");
Class[] returnTypes = new Class[] { String.class };
Object[] args = new Object[] {};
// Exception occurs on the next line
Object[] response = serviceClient.invokeBlocking(methodName, args,
returnTypes);
serviceClient.cleanupTransport();
String fileServers = (String) response[0];
return fileServers
} catch (Exception e) {
e.printStackTrace(out);
return "0";
}
}
Я получаю следующую ошибку Axis2:
org.apache.axis2.AxisFault: The server did not recognise the action which it received:

Интересный аспект заключается в том, что когда я запускаю класс DownloadServer как обычное Java-приложение (не вызывается как веб-служба), я не получаю того же исключения.
Кто-нибудь знает, что может быть не так, когда тот же код выполняется в качестве веб-службы?
