Допустим делаю веб сервис на AXIS2 (только потому, что supports SOAP 1.1 and SOAP 1.2), необходимо реализовать передачу информации о ошибках на строне сервиса, в примере (faulthandling) у AXIS2 видел что можно возбуждать исключения на сервисе и ловить их на клиенте
код сервиса

package example;
/**
* BankServiceSkeleton java skeleton for the axisService
*/
public class BankServiceSkeleton{
/**
* @param param0
*/
public example.WithdrawResponse withdraw(example.Withdraw param0)
throws InsufficientFundFaultMessageException,AccountNotExistFaultMessageException{
final String account = param0.getAccount();
if (account.equals("13")) {
final AccountNotExistFault fault = new AccountNotExistFault();
fault.setAccount(account);
AccountNotExistFaultMessageException messageException = new AccountNotExistFaultMessageException("Account does not exist!");
messageException.setFaultMessage(fault);
throw messageException;

Это соответствует спецификации SOAP?
или
Могут ли к такому сервису писаться клиентские приложения на С++, С? Необходимо ли использовать какие-то дополнительные либы? |
