Cannot modify VCD Public Proxy Console - class java.lang.NullPointerException

Hello

I get an error when I try to put the IP address of the form of VCD Public Console Proxy web UI.

When I want to confirm the changes with the button apply the following error occurs - 'class java.lang.NullPointerException '.

The log file shows some additional information, but this does help me solve the problem.

VCloud Director version is 5.5 and the CentOS operating system.

I hope someone can help.

Solved the problem by directly inserting the values into the database of the vcloud Director.

We found values in 'dbo.config' and change the 'value' for

'consoleproxy.external.address '.

"restapi.baseUri" and

'system.external.link '.

In our case there no had no entry for this three values so we created the entries.

Now everything works fine.

  • Cannot convert abcd of the type class java.lang.String interface java.util.List

    Hello

    I get an error of "cannot convert the class type abcd java.lang.String interface java.util.List" where "abcd" is a string in a listbox.

    and my code is something like this

    < af:selectOneListbox id = "lstcatg" label = 'List of categories' partialTriggers = 'proud '.

    value = "#{viewScope.RegWoComp.lstboxcatg}" >

    < f: selectItems id = value="#{viewScope.RegWoComp.customList}"/ "lstselect1" >

    < / af:selectOneListbox >


    bean

    private list < String > lstboxcatg;

    {} public void setLstboxcatg (List < String > lstboxcatg)

    This.lstboxcatg = lstboxcatg;

    }

    public List < String > getLstboxcatg() {}

    Return lstboxcatg;

    }

    public BindingContainer {} getBindings()

    Return BindingContext.getCurrent () .getCurrentBindingsEntry ();

    }

    Private Sub button (ActionEvent actionEvent)
    {
    JUCtrlListBinding listBindings = (JUCtrlListBinding) getBindings () .get (lstboxcatg);
    Object [] str = listBindings.getSelectedValues ();

    for (int i = 0; i < str.length; i ++)

    {

    System.out.println (STR [i]);

    }
    }

    I tried to use this fact.

    object str = listBindings.getSelectedValue ();

    System.out.println (STR);

    and here, if I change the data type of lstBoxcatg

    private String lstboxcatg;

    {} public void setLstboxcatg (String lstboxcatg)

    This.lstboxcatg = lstboxcatg;

    }

    public String getLstboxcatg() {}

    Return lstboxcatg;

    }

    can I get a nullpointerexception on line object str = listBindings.getSelectedValue ();

    No you can use this code you don't use link layer

    remove this code. You will get the selected value in this string variable

    Just write this about you button action and verification.

    System.out.println (selectedVal);

    My question is how do I find in my page jsff?  I see that it is on a property of disabled but I don't know which and there are many on this page.  I think it's one that looks like this: disabled = ' #{bindings. " "{PGSchedType.inputValue No 5}.  If my different EL expression?

    Thank you.

    Hi Rudy,.

    I guess that you have spotted it right. Instead of 5 in your disabled property, use '5'


    I mean, just surround it with quotes like below


    disabled="#{bindings.PGSchedType.inputValue ne '5'}"
    

    Thank you

  • Cannot convert oracle.jbo.domain.DBSequence to class java.lang.Integer

    Hello

    I have the following problem with my ADF application developed in JDeveloper 12.1.3:

    In my model, there are two entities MeterEO and MeterTypeEO with the following attributes:

    MeterEO

    TenantIdBigDecimalTENANT_IDNUMBER
    MeterCodeStringMETER_CODEVARCHAR2 (48)
    TypeIntegerTYPENUMBER

    MeterTypeEO

    IDDBSequenceIDNUMBER
    Name of the vendorStringNAME OF THE VENDORVARCHAR2 (32)
    TypeStringTYPEVARCHAR2 (16)

    Type of MeterEO reference Id in MeterTypeEO.

    Appropriate VO of the meter uses a MeterTypeVO LOV to create a list containing the provider and Type as well as the user's selection.

    In the ModelTester, everything works well when I try to change a counter, select a new type and validate my changes to the database.

    A JSFF, it looks quite different. Selection is made by SelectOneChoice with the LOV list containing the provider and Type. Of the LOV the appropriate values are selected for the (integer) to the meter, then the user gets a readable text instead a few cryptic. But when I change the value by selecting a new choice I always got the error ' Can' oracle.jbo.domain.DBSequence to class java.lang.Integer.

    Why it works without problems in the Modeltester but not on the page?

    Screenshot 2015-08-31 12.48.55.pngScreenshot 2015-08-31 12.49.09.png

    Please see the attached screenshots to make it clearer what I mean.

    Any hint is appreciated,

    Björn

    I solved my problem now in view objects. Maybe someone who has the same problem and is interested in the solution:

    In MeterTypeVO - which is the source for the LOV - I added a new transitional field called IntId of type Integer that refers to the field Id of type DbSequence by Expression. DbSequence is automatically converted at length which can be also automatically converted in full.

    At the counter, I changed the key of the LOV to IntId instead of code.

    It works like charm.

  • java.lang.NullPointerException - sorry!

    Hello

    I get a null pointer exception and cannot pinpoint why. I have two VO - one associated with a menuchoice element and it works fine. When an item of menu choice is selected, and the subject button, I want to run another VO and get all the details of the returned row. This VO does not appear, I want just the values of the query. Just happens when I try to do anything with the line of the second Vo.

  • BlackBerry Smartphones untrapped exception: java.lang.NullPointerException on silent incoming call

    I got an incoming call and I hit him either the top or to the bottom of the volume button to turn off the sound.  The ringtone to silence, then the unsilenced ringtone 1 second later.  Then I hit the top or to the bottom of the volume once again button, then he silenced and I received this error message:

    Eception exception: java.lang.NullPointerException

    I clicked on OK and everything works fine.  Is there any solution for this and should I be worried?  I am running v4.7.1.40 (Platform 4.1.0.40).

    HI and welcome to the Forums!

    Untrapped exception happen - they are basically an event for which there is no program on the device to manage code. It's like a mistake on a computer--sometimes they straight. Future updates will probably help with some. A few things to check and try:

    (1) make sure you are on the latest OS for your business... you can check your carriers latest version certified through this Portal:

    http://NA.BlackBerry.com/eng/support/downloads/download_sites.jsp

    (2) a Hard Reboot:

    Whenever random strange behaviors creep, the first thing to do is a battery pop reboot. With power ON, remove the hood back and remove the battery. Wait a minute, then replace the battery and cover. Power on and wait patiently through the long reboot - about 5 minutes. See if things return to functioning. Like all computing devices, BB suffers from memory leaks and others... with a hard reboot is the best remedy.

    (3) good memory management:

    There are three types of potential memory on a BB: 1) application memory, the device memory) 2 and 3) Media/SD memory card

    Application memory - it is the most important; It is protected (not available to the user), dedicated and (fixed size) space as the destination for the installation of applications (more a few storage applications, overhead and other costs). You can't touch AppMemory. You cannot improve the maximum AppMemory that your BB has. It is what it is. Applications can install only here... There is no other choice.

    The device memory - it is space on your BB you can touch these files, images, media, etc. In general, it is not very big, but it is available.

    Memory card SD/Media - is what it says... your SD card to store files, media, photos, etc.. It can be as large as your BB OS can support... see this KB:
    http://www.BlackBerry.com/BTSC/KB05461

    On some devices/OS levels, enforcement and the memory of the device are combined into "free file"... This is, IMO, a little more difficult to administer that you can't see really how AppMemory you have. Nevertheless, here are some tips to use:
    http://www.BlackBerry.com/BTSC/KB15345
    http://www.BlackBerry.com/BTSC/KB14320
    http://www.BlackBerry.com/BTSC/KB14213

    Finally, it is always important to correctly close applications when you are finished with them. Using the back or on the red button won't do that - those leave the app to decide what to do... and some let themselves memory-resident, consumes resources on your BB, slowing down the overall performance. Rather, to close an application, press the BBKey and select 'Farm' or 'Quit'... that forces the application to be closed, freeing for your new use the resources it consumed. Some applications will always be running (in general - BBMessenger, browser, homescreen, phone and Messages)... but, you should always close them properly - especially the browser... If we leave on a web page, it will not consume only additional resources, but the power of the battery as well.

    Good luck!

  • Error java.lang.NullPointerException for blackBerry Smartphones verifying my SMS Inbox

    Need help with my BB 9000...

    Hello!

    There is virtually no diagnosis of those - they are the equivalent of random errors in Windows for which trace the root cause is futile. Basically, here's the last out in the programming code - some event occurred for which there is no event handler in the code. The patch is an update of the code that handles the event... but, again, what is the event is almost impossible. So, there are a few things to try:

    Sometimes, the code simply is damaged and needs to be updated - just like a reboot:

    • Each time a random strange behavior or slow creeps, the first thing to do is a battery pop reboot. With power ON, remove the hood back and remove the battery.

Like all computing devices, BB suffers from memory leaks and others... with a hard reboot is the best remedy.

    There may be a code updated to the value of the carrier - check out them through this Portal:

    The toughest possible causes are a bad application behave. To find it, we need to eliminate apps one at a time, wait a while between the two (I usually recommend a week), until the problem stops... revealing the offending application.

    Good luck and let us know!

  • Pure SQL Exception: Caused by java.lang.NullPointerException.

    Could not invoke the 'Query_XX_Flag' against the 'db' operation due to: []

    LIAISON. JCA-11633

    Pure SQL exception.

    Pure SQL select DECODE Execute (MSI. ATTRIBUTE5, 'Y', 'True', 'False') XX_flag of msi mtl_system_items_b where inventory_item_id =? and rownum = 1 failed.

    Caused by java.lang.NullPointerException.

    The pure SQL option is for only border use cases and provides simple but minimal functionality.  Maybe try the "Run an operation on a table" option instead.  This exception is considered non reproducible, probably due to an error of modeling.

    Version: Oracle soa suite 12.1.3 - jdk1.7 - (local) Windows 7 operating system

    I get the above exception in one of our Async BPEL of the process, and it happens like 1 in 5 cases.

    As you can see, the reason for the error is not really clear and I see nothing diagnosis either connects.

    And when I start this process from the console, it's getting completed successfully.

    We are not exceeding the number of DB connections either.

    Here's our design:

    BPEL Poller-> (several calls) Async BPEL process-> database adaptor with above query

    What could be wrong? What is the reason for this odd behavior?

    Thank you

    Prasanna

    This error could not be reproduced on the test environment, where the SOA server with oracle DB of the backend rather than javaDB on integrated server is installed...

    So if someone were unexpected exceptions on the local server and then try to test on the test/UAT/pre-production environments.

    Hello

    You cannot print in newspapers, a document, an object, so here is the Code

    declare the saxon namespace = "http://saxon.sf.net/";
    declare namespace xsl = "http://www.w3.org/1999/XSL/Transform";

    Let $osmOrder: = fn:root (.) OMS:GetOrder.response
    Let $inputXml: saxon =: serialize($osmOrder, )

    Now you can print this
    in using this

    log:info($log,$inputXml)

    Either way, my name is Brigitte.
    Thank you

    The cause:

    There is a signed applied and it is to be embedded within an Internet explorere, once the page is iconified and after that maximized. The applet cannot be repained and the background color of the applet is black. This isn't a common occurrence; Sometimes.

    It would be great if I can get some thoughts on this problem.

    Any body has met with such a problem?

    Thank you

    You don't have to honor the single threaded swing rule. All methods of Swing [with a very few exceptions, such as repaint()] and constructors should be called in the EDT.

    I just had some problem to be able to print a PDF file that has sent me a reliable source of the school. He could not open with precision and would not print. I was told a few undesirable and the part of it said:

    User CMN3101E the system is unavailable due to "java.lang.NullPointerException".

    I then Googled that and found the I needed to have the video drivers Intel and not the versions of MS due to some problems. I went through all this mess by using Device Manager and switched 2 pieces of diff for Intel drivers Intel and not versions of MS. I also did an UPDATE MS after a reboot to ensure that another MS Update would not reinstall certain versions of MS and if he found them I wanted to mark them for future IGNORES and ignore them now.

    Still no go. I need help big time. Does anyone for a small iJEFF help today¿

    Hi Jeff,

    1. What is the brand and model of the printer?
