DistributedMember is null in the implementation of the Interface Authenticator?

DistributedMember is null in the implementation of the authenticator Interface.

http://www.gemstone.com/docs/current/product/docs/JAPI/com/gemstone/GemFire/security/authenticator.html

Main authenticate (Properties props, DistributedMember member)

Check the credentials provided in the properties for the client/peer such as specified in the Member ID and returns the main partner of the customer/peer

I'm trying to implement authentication. I DistributedMember object as null in the newspapers of Locator when counterpart try to join the distributed system.

Even if I take the method AuthenticationFailedException authenticate; my Member is still able to join the system of Distribuyed. It's somehow connected to locator * .dat file?

Messages processed on the thread "UDP incoming Message Handler" are messages of closure of the process itself.  I looked at the code that calls the authenticator and it always affects the null member ID in this case.  I don't know why, but it's what he does.  In addition, in this case it deals a membership VIEW and not a request to join the system.

You can safely ignore the requests with a null member ID.

The client authentication is not handled by the Locator well - it is managed by the cache servers when the client tries to connect to them.  Only process GemFire "peer" are authenticated by locators.

I hope this helps.  I shall notify the Department tech pubs on this subject so that they can update the documentation.

  • I get a JavaScript Application error: "setTimeout" called on an object that does not implement the interface Window for Firefox.

    I get a pop up box with the message: Application JavaScript error: "setTimeout" called on an object that does not implement the interface Window for Firefox.

After all a half dozen, she disappears - until what I move to another part of Amazon! I uninstalled - reinstalled and then - Firefox and BA. I do not understand this!

    Hello

    Try Firefox Safe mode to see if the problem goes away. Firefox Safe mode is a troubleshooting mode that temporarily disables hardware acceleration, restores some settings and disables add-ons (extensions and themes).

    If Firefox is open, you can restart Firefox Safe mode in the Help menu:

    • In Firefox 29,0 and above, click on the menu button

      click Help

      then select restart with disabled modules.

    • In previous versions of Firefox, click on the Firefox button in the upper left of the Firefox window and click help (or click on help in the Menu bar, if you do not have a Firefox button) and click on restart with disabled modules.

    If Firefox is not running, you can start Firefox in Mode safe mode as follows:

    • On Windows: Hold down the SHIFT key when you open the desktop Firefox or shortcut in the start menu.
    • On Mac: Hold the option key during the startup of Firefox.
    • On Linux: Exit Firefox, go to your Terminal and run firefox-safe-mode
      (you may need to specify the installation path of Firefox for example/usr/lib/firefox)

    When the Firefox Safe Mode window appears, select "start mode safe."

    If the problem is not present in Firefox Safe Mode, your problem is probably caused by an extension, theme or hardware acceleration. Please follow the steps described in the section Troubleshooting extensions, themes and problems of hardware acceleration to resolve common Firefox problems to find the cause.

    To exit safe mode of Firefox, simply close Firefox and wait a few seconds before you open Firefox for normal use again.

    When find you what is causing your problems, please let us know. This might help others with the same problem.

    Table: digital_val

    of digital_val

    I'm more curious why, when you select 2 rows, you expect a result of row?

    WITH digital_val

    AS (SELECT 1 AS 'Sno', 'San1"C1, c2 FROM DUAL 11)

    UNION ALL

    2 SELECT AS 'Sno', 'San2"C1, c2 FROM DUAL 22)

    SELECT CASE WHEN c1 is "San1" THEN END AS A c2.

    CASE WHEN c1 = "San2" THEN END AS B c2

    OF digital_val;

    With no other input, if you select 2 rows, you get 2 rows.  One of the other solutions use a max function, but is this really what you want, does not specify?

  • lov automatic setting of null at the click of a button.

    Hi Experts ADF,

    JDeveloper 12.1.3.0.0

    I have a read-only VO as below which is dragged as a selectone choice. Do autosubmit = 'true '. I also have a valueChangeListener. In the valueChangeListner value, I'll put in an instance variable.

    And I have an Add button that partial shipment is set to true. But when the click on the Add button, inside actionListener, I get the value null for the instance variable.

    When I select a value, select a choice, I am able to see the value of valueChangeListener. The valueChangeListener inside I'll highlight selectedValue = valueChangeEvent.getNewValue;

    After I click on the Add button, in the actionListener I get selectedValue as null.

    Note: -.

    selectedValue is a variable instance with the getter and setter.

    The taskflow scope is backingbeanscope.

    Read only Vo:-select DepartmentId, DepartmentName from departments dragged like a selectonechoice.

    Thank you

    Roy

    Instead of the instance variable, save the value of the variable def page, as described here:

    on this path, the value will survive another request

  • Add the constraint not NULL in the existing table that has null values

    Hello

    I want to add a constraint not null to and an existing table, but the table already contains values null in this column.

    EMP

    Emp_id name

    1 axada

    2

    3 sdkdd

    Here is already the data IE 2 empid is Null as name. I must add a fool of constraint not null which new values will not be null, but I don't want to change the data of exisitng alreadt which is null.

    Hello

    "The opposite": NOVALIDATE does not validate the data that is ALREADY in the table, but do not allow the insertion of a NULL value.

    Have you tried my sample code?

    CREATE TABLE MaTable (x NUMBER PRIMARY KEY, y NUMBER);

    INSERT INTO myTable VALUES (1, 123);

    INSERT INTO myTable VALUES ( 2, NULL );

    INSERT INTO myTable VALUES (3, 456);

    ALTER TABLE mytable MODIFY (y NOT NULL NOVALIDATE );

    INSERT INTO myTable VALUES (4, 678);

    INSERT INTO myTable VALUES ( 5, NULL );

    SELECT * FROM MyTable;

    '2' line was inserted with null before the creation of the NOT NULL constraint, this line remains "as what" at the end of the trial.

    '5' line trying to insert a NULL value after creating the NOT NULL constraint, which is denied.

    Some columns of the values of the selected line returns NULL in the table of the adf.
     
			 Hello..
    

    
My version of jdev 11.1.1.5.0
    

    I have a vision with some columns. This view is mapped to a table of adf with some of the displayed columns. My task is to get the column values selected line (including the values of the column not displayed).
    But I'm certain values such as null, although there are values present when I run the query from the view.
    My code:
    
DCIteratorBinding tableVO = ADFUtils.findIterator ("myVO");
    
ViewObject voTableData = tableVO.getViewObject ();
    
Line rowSelected = voTableData.getCurrentRow ();
    

    

    + / / codeto display column and the values +.
    
int x = 0;
    * for (the names of the objects: rowSelected.getAttributeNames ()) {*}
    

    * for (int i = x; i < rowSelected.getAttributeValues () .length; i ++) {*}
    * System.out.println (x + "." + name + "=" + rowSelected.getAttribute (i)); *
    
break;
    *}*
    
x ++ ;
    
continue;
    *}*
    

    

    MY table:
    * < af:table value = "#{bindings.myVO.collectionModel}" *.
    * var = "row" rows = "#{bindings.myVO.rangeSize}" *.
    * EmptyText = "#{Bindings.myVO.Viewable?" "{'No data to display.': 'Access Denied.'}". *
    * fetchSize = "#{Bindings.myVO.rangeSize}" *.
    * rowBandingInterval = "0."
    * filterModel = "#{Bindings.myVO.queryDescriptor}" *.
    * queryListener = "#{Bindings.myVO.processQuery}" *.
    * filterVisible = "true" varStatus = "vs."
    * selectionListener = "#{myBean.method_onRowSelect}" *.
    * rowSelection = "single" id = "t1" styleClass = "AFStretchWidth."
    "* partialTriggers =": sbcClose: sbcOpen: socWarehouse. "
    * inlineStyle = "height: 217px;" / > *.
    

    

    Thank you			 
    Question: the attributes are not null in the DB?
    The attributes are part of the past of the query select?
    And they are part of the binding of the tree?

    Solid and sketched movement Null follow the same path, but in different places.
     
			 
    I'm editing on After Effects cs6. First, I will describe two situations and what I 'm able to do it, then I will explain what is the heart of the problem.
    First situation: when you use 'motion tracker', I'm going to "Change the target" of a null I titled 'Tracker '. As you know, this will allow my null to track movement on caterpillars and synchronization with the movement of my video. It worked well.
    Second situation: Let's say I have a white canvas and simply stick to a null value. I take this null and draw a few sketches everywhere motion that I love. Then I take a solid. I have an effect as an 'Individual' to this massive. Now, if I take the "XY Position" of this effect and make a selector to the position of my movement sketched null, the effect will now follow the path that I have outlined. It worked as well.
    My problem: I tried to combine the two situations above, in order to get my movement sketched special effect for synchronization with the video track. I tried this by first taking of null value "Tracker" my goal for motion tracking (1st situation). Then I sketched movement a 2nd null. I pick whipped this 2nd null for "Tracker" and the sketch to synchronize with my video successfully obtained.
    HOWEVER, once I tried a particular effect with the path of my sketch of movement of synchronization (2nd case), I found what happens: my particular effect was indeed following the path of my movement sketched null, but it was displayed in the upper left corner of my screen, WAY OFF from where my movement sketched null has been placed in fact. So sketched movement null and the special effect were both the same way, but not in the same place.
    My question: How can I synchronize my effect go exactly where I want it (with a null value of movement sketched) and still get it to follow along with my video? I know it's difficult to describe without showing it directly in person, but I hope it's a simple question that has a simple answer with him.
    			 
    Mylenium
    

    As described in my first post: when pick - whip sketched movement Null Null in Tracker, following the path outlined particular effect, but was suddenly moved to another point in the frame.

    However, there was a simple solution to this problem after all. For those who are interested, once the setting of Position XY of the particular effect pick-whipped in the movement sketched Null, not NOT-selector of the said Null value Null of Tracker. Instead, pick - whip solid [which has the particular effect] on the Tracker Null toured and everything is aligned.
    

    But thanks for the idea!

    NULL in the detailed report?
     
			 Hi all
    

    I am using two sets of data in a report (q1, q2)
    

    first part of the report presents the results as expected (q1).
    

    (q2) second part of the report shows record null in the first line?
    

    Why does this happen? any idea? If the data are not sufficient to answer please ask me question...?
    

    Thank you.			 
    Look in your Inbox for the answer.

    Dynamically loading the interface from a remote source implementation class
     
			 
    Hello guys,.
    I'm kind new to AS3, please bear with me.
    I'm working on a project were I want to implement some sort of MVC. The idea is this: have an application Viewer that connects to a database and reads the object to display (based on some ID); have an app Setter that connects to the database and sets the object to display for a particular ID.
    What I'm trying to do is to have an interface that declares the common methods for the object class (like the draw, etc.) and have implementations of this interface be dynamically loaded from the database in the Viewer.
    Is this possible? I still think about it in the right way?
    I'd appreciate any suggestions really.
    Thank you

    Connections container is null after the closure of a stubborn workflow
     
			 Hi, after closing a stubborn workflow open in a modal window expression
    

    BindingContainer DCBindingContainer is getLovFieldBinding () .getBindingContainer ();.
    

    Returns the value null inside the bean point JHeadstart LOV. The same code is run correctly in all other scenarios. The workflow is closed normally accessing a special return flow rule and after you close the window other scenarios that use link containers are normally carried out unless this point bean LOV.
    

    Any comments will be useful,

where customer_id = customer_

    is there any way to write this without dynamic sql. cusomter_id field is always bear value.
