我有一個名爲DownloadServer的Axis2 Web服務，它調用另一個名爲Publisher的Axis2 Web服務。他們部署在同一臺服務器上。這是兩個Web服務的代碼。從另一個Web服務調用Web服務時出現Axis2錯誤
在課堂Publisher.java：
public String getFileServers(){
return "http://localhost:8080/axis2/services/FileServer1?wsdl http://localhost:8080/axis2/services/FileServer2?wsdl";
}
在課堂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";
}
}
我正在以下Axis2的故障：

有趣的方面是，當我運行DownloadServer類作爲普通Java應用程序（不作爲Web服務調用）時，我不會t得到相同的例外。
有沒有人有任何想法當相同的代碼作爲一個Web服務執行時可能會出錯？
