WMIを通じてJava J-Interop

Question

これまでWMI、J-interop lib COMの通信を通じてJava...い条件を物理メモリのデータからリモートシステム。

以下のようなコード:このデータが一部欠陥っているようにしていま2gbのメモリマシステムの二つのメモリーカード1GBそれぞれこのコードだけを示してい1gbのメモリ:

力を貸してくださいに整流すると以下のコードも参考に従J-Interopの良い例：

JISession dcomSession = null;
try {
dcomSession = init(domain, username, password);
JIComServer comServer = new JIComServer(valueOf("WbemScripting.SWbemLocator"), hostname, dcomSession);
IJIDispatch wbemLocator = (IJIDispatch) narrowObject(comServer.createInstance().queryInterface(IID));

Object[] params = new Object[] { new JIString(hostname), new JIString("ROOT\\CIMV2"),
        JIVariant.OPTIONAL_PARAM(), JIVariant.OPTIONAL_PARAM(), JIVariant.OPTIONAL_PARAM(),
        JIVariant.OPTIONAL_PARAM(), new Integer(0), JIVariant.OPTIONAL_PARAM() };
JIVariant results[] = wbemLocator.callMethodA("ConnectServer", params);

IJIDispatch wbemServices = (IJIDispatch) narrowObject(results[0].getObjectAsComObject());

final int RETURN_IMMEDIATE = 0x10;
final int FORWARD_ONLY = 0x20;

params = new Object[] { new JIString("SELECT * FROM Win32_PhysicalMemory"), JIVariant.OPTIONAL_PARAM(),
        new JIVariant(new Integer(RETURN_IMMEDIATE)) };
JIVariant[] servicesSet = wbemServices.callMethodA("ExecQuery", params);
IJIDispatch wbemObjectSet = (IJIDispatch) narrowObject(servicesSet[0].getObjectAsComObject());

JIVariant newEnumvariant = wbemObjectSet.get("_NewEnum");
IJIComObject enumComObject = newEnumvariant.getObjectAsComObject();
IJIEnumVariant enumVariant = (IJIEnumVariant) narrowObject(enumComObject.queryInterface(IJIEnumVariant.IID));

Object[] elements = enumVariant.next(1);
JIArray aJIArray = (JIArray) elements[0];

JIVariant[] array = (JIVariant[]) aJIArray.getArrayInstance();
for (JIVariant variant : array) {
    IJIDispatch wbemObjectDispatch = (IJIDispatch) narrowObject(variant.getObjectAsComObject());

    // Print object as text. Optional - comment if not needed
    JIVariant[] v = wbemObjectDispatch.callMethodA("GetObjectText_", new Object[] { 1 });
    System.out.println(v1[0].getObjectAsString2());
    System.out.println(wbemObjectDispatch.get("DataWidth").getObjectAsInt());
    System.out.println(wbemObjectDispatch.get("Status").getObjectAsInt());
    System.out.println(wbemObjectDispatch.get("Speed").getObjectAsInt());
    System.out.println(wbemObjectDispatch.get("FormFactor").getObjectAsInt());
}
} catch (Exception e) {
e.printStackTrace();
} finally {
if (dcomSession != null) {
    try {
        JISession.destroySession(dcomSession);
    } catch (Exception ex) {
        ex.printStackTrace();
    }
}
}

必要なものをカウント内の要素についての一覧取得を行います。にj-interop例MSIWMI2.java.ここでは例のカウントの一覧取得を行います。

...
results = wbemServices_dispatch.callMethodA("ExecQuery", new Object[]{new JIString("select * from Win32_OperatingSystem where Primary=True"), JIVariant.OPTIONAL_PARAM(), JIVariant.OPTIONAL_PARAM(),JIVariant.OPTIONAL_PARAM()});
IJIDispatch wbemObjectSet_dispatch = (IJIDispatch)JIObjectFactory.narrowObject((results[0]).getObjectAsComObject());
JIVariant variant = wbemObjectSet_dispatch.get("_NewEnum");
IJIComObject object2 = variant.getObjectAsComObject();

IJIEnumVariant enumVARIANT = (IJIEnumVariant)JIObjectFactory.narrowObject(object2.queryInterface(IJIEnumVariant.IID));

JIVariant Count = wbemObjectSet_dispatch.get("Count");
int count = Count.getObjectAsInt();
for (int i = 0; i < count; i++)
{
        Object[] values = enumVARIANT.next(1);
        JIArray array = (JIArray)values[0];
        Object[] arrayObj = (Object[])array.getArrayInstance();
        for (int j = 0; j < arrayObj.length; j++)
        {
            IJIDispatch wbemObject_dispatch = (IJIDispatch)JIObjectFactory.narrowObject(((JIVariant)arrayObj[j]).getObjectAsComObject());
            JIVariant variant2 = (JIVariant)(wbemObject_dispatch.callMethodA("GetObjectText_",new Object[]{new Integer(1)}))[0];
            System.out.println(variant2.getObjectAsString().getString());
            System.out.println("++++++++++++++++++++++++++++++++++++++++++++++++++++++++++");
        }
}
...

このコードからMSWMI2.java のorg.jinterop.dcom.試験パッケージです。
