CORBA通知訂閱（錯誤：org.omg.CORBA.MARSHAL：vmcid：0x0次要代碼：0完成：否）

Question

我試圖訂閱通知服務和類似於（org.omg.CORBA.MARSHAL: Server-side Exception: null）！的消費者警報，但獲取編組錯誤。非常感謝，如果有人能幫我解決我失蹤或做錯的事情。

idls文件從NotificationIRP idls和使用jacorb-3.5 api。

    String vers[] = nOps.get_notification_IRP_version(); 
    for (String ver : vers){ 
    System.out.println("notification IRP version is: " + ver); 
    } 

    String resp = nOps.attach_push(manager_reference, time_tick, cats, filter); 

    //print subscription ids 
    String subs[] = nOps.get_subscription_ids(manager_reference); 
    for (String sub : subs){ 
    System.out.println("subscription id: "+sub); 
    } 

    } catch (Exception ex){ 
    System.out.println ("ERROR: " + ex);

} }

結果

Answer 1

問題，我在這裏的猜測是，你需要你正在使用後在ORB.init正確的命名服務在新的CORBA之前添加註冊商（）。當你使用orb傳遞任何對象時，它會嘗試檢查它是否已經被任何服務註冊。否則它開始編組數據。我正在尋找你的代碼將盡快找到解決方案

Answer 2

你知道嗎？ 我試圖用同樣的方法連接到愛立信Corba北向接口，但使用Perl，而不使用Java。

您發送錯誤的對象attach_push（），對象類型需要準確地：

• manager_reference：純字符串，
• time_tick：ManagedGenericIRPConstDefs :: UnsignedLongOpt，不是int在你的代碼！
• cats：NotificationIRPConstDefs :: NotificationCategorySet，不是字符串數組。
• filter：ManagedGenericIRPConstDefs :: StringOpt，不是字符串。

而且，你要發送的貓所有類別但包括事件和QoS。對於事件，您需要使用專有的EventIRP而不是NotificationIRPSystem和qos，這可能不需要。對於警報，您只能使用一個類別「1f1」。在Perl中，它是這樣做的：

my $category_set=NotificationIRPConstDefs::NotificationCategorySetOpt->new(); 
$category_set->value(["1f1"]); 

試圖找出Java中的相同的東西。它還沒有爲我工作，工作仍在進行中......
