Как часть кода может быть выполнена, если «ответ HTTP» не был успешно отправлен на метод веб-службы JAX-WS

Question

У меня есть следующие услуги:

@WebService(serviceName = "ServiceXPTO") 
public class ServiceXPTO { 
    @EJB 
    private XPTO ejbRef; 
    @WebMethod(operationName = "webmethod1") 
    public Method1Result webmethod1(
      Method1Request request) { 
     return ejbRef.ejbmethod1(request); 
    } 
} 

Как я могу сделать некоторые код запуска, если после возвращения из webmethod1 есть некоторая ошибка сокета, вызванная отключением клиента и т. д.?

Для примера: если java.io.IOException происходит, я хотел бы ejbRef. method1Error (...) можно назвать ...

Реальная Исключение:

Answer 1

Вы можете использовать try/catch

public Method1Result method1(
     Method1Request request) { 
    try{ 
     return ejbRef.method1(request); 
    } catch(IOException e){ 
     //catch IO exceptions 
     return ejbRef.method1Error(request); 
    } catch(Exception e){ 
     //other exceptions 
     return ejbRef.method2Error(request); 
    } finally{ 
     //this will always be executed after the try block 
    } 

}
