Cannot use clone() method of LinkedList...That's strange

I got a very strange problem. I wrote the following statement:
Integer[] nums = generateRandomIntegerArray();
List<Integer> list = new LinkedList<Integer>(Arrays.asList(nums));
List<Integer> clone = list.clone();
.....I got an error statement: cannot find symbol-method clone().
When I use other methods it's fine, but I cannot use clone().
That's really strange. I've checked many times, clone() method does exist
in the LinkedList class.

Your list variaiable is to an object implementing the interface List and clone is not part of the List interface. To get to the clone method you must cast it back to LinkedList, or use a LinkedList reference.

Plugin for Acrobat Reader cannot use DigSig methods?

Hi,
I have an acrobat plugin created using acrobat sdk 9, registered using PubSec. Now, i want to make it run for adobe reader aswell. but i read the following somewhere:
You may not use the Adobe Reader key to develop or enable your plug-in or any other software or hardware to perform or enable any of the following:
Add functionality to Adobe Reader that is substantially similar to functionality in commercially available Acrobat products
Accept navigational commands from an application other than Adobe Reader
Create, remove, or modify any Enabling Rights (including but not limited to permissions added to a PDF file with a product such as Adobe LiveCycle™ Reader Extensions (formerly Adobe Reader Extensions Server)
Save or modify any Acrobat file (including without limitation PDF, FDF, or annotation)
Extract and save any content from a PDF file (other than submitting form data to a remote server)
Use any APIs from the Forms or DigSig Host Function Tables (HFTs)
Modify the appearance of Adobe Reader
Remove the menu item that calls up the "About" screen in Adobe Reader
Implement a Replacement File System (RFS) for Adobe Reader"
Does this mean that i cannot use a plugin registered using DigSig HFT OR that i cannot use DigSig methods in my plugin, which i have used generously?
If the latter, then does this mean i'll have to remove all DigSig method usage from my plugin?
Thanks

It means you need a special Reader-enabling license. When you send in your Reader IKLA (integrated key license agreement) you need to specify that you are doing something related to DigSig so that they can send you the revised agreement and pricing model.

What time should I use clone method?

Hi everyone:
There is a problem puzzled me all the time. You know,If I want to use a object I could use the code:
Class A=new Class(); I get a object A so I can use it. But there is a method called "clone".It's function is copy a object.But Why jdk have this method.Is there any useful ?
I mean that what situation should I use the "clone " method?
Thks!

a regular clone copies all members of an object by reference. You can implement the Clonable interface to provide a clone which makes a 1:1 copy of your object, so no references are copied over. This ensures that the objects don't share the same objects, but do have the exact same content.

Cannot use clone/healing in certain layers.

I'm using Ps CS5 to process my photos. My workflow generally starts with background layer, add adjustment layers and smart layers for plug ins for the general stuff. Once the Image is Generally good, I like to "repair" with either the clone stamp or healing brush. This was not a problem before I wanted the flexibility I have by saving layers. Now when I try to use these tools I get messages such as " ...cannot be used in an adjustment layer, or layer contains no image or pixels, or ...cannot be used in a smart layer(I think?)... There is something very basic about using layers, such as which ones have content,(I guess?), that I don't understand. Explanations for using layers are about as clear as mud for me! It would be nice if instead of Ps reminding me that I'm a dummy when I try to use these tools, that it would offer a solution. For example: "if you would like to use the Healing Brush tool, you must first ______ _______ _______ the current layer." Or something like that. I've tried to make only the layer that I'm working in visible. This works great, until I bring back the other layers and my repairs disapear into Adobe's dark dungeon.I suppose It may be that it would help to flatten layers or something like that, but I do want to have the ability to go back and make minor adjustments in the future.

Ah, understanding Layers. Due to the power, and resultant complexity, the full concept of Layers can be tough to grasp. For many of us "old-timers," it was actually easier, as we had worked with acetates in analog art. All we had to do was interpolate that knowledge to the digital world, and then quit screaming "golly, gee-whiz!" with every revelation in the digital world. Every second spent learning the ins and outs of Layers will pay big dividends.
Just looked over Acres' link, and that does look like a good place to start. Knowledge of Layers is a multi-step building process, and having a great foundation is step-one.
Heck, I have been using Layers, and at a fairly high level for well over a decade, and learn something new, almost every week. I have to stiffle those "golly, gee-whizzes... "
Most of all, glad to have helped, and I wish you luck with Layers. If you do find some more useful resources, do not hesitate to update this thread with them. Others will likely benefit from those.

I cannot use maps in india, n thats shame for ios6

I was trying to use maps on ipad2 and iphone 4, i was helpless to use it. Called up coustmer care and they replied ios6 is not feasible for india. Why? Fr the kind information of apple , india has the greater commercial market of phone users. I was a great fan of apple, but now i regret to be one of. Apple has to reply on this comment when it can be solve. I am completely relaying on apple product. Instead of concentrating on rubbish publicity u guys should really look at our problem. Rest of the application are good. But maps? The most important thing in apple is missing. Really missing steve jobes hand on it. I request you to please check news papers for the same.

You cannot downgrade. Do a search in the forum and you will find alternatives that might help you solve the Map problem.
The easiest one is to add the maps.google.com link to your homescreen. It is not perfect but it works.

Cannot use clone and heal brushes

I've followed the video of how to use these brushes, but whenever I select either of them, I either get a "hand" or a small cross, neither of which allow for selecting the areas of be healed/cloned. What am I doing wrong?

As you increase the brush size you should see a cross in the middle. That is the sampling point, e.g. the area you click on that you wish to heal or clone out. As soon as you click or drag the hand appears with the suggested area to be copied (usually a nearby sample with a similar color) You can drag the with the hand, if you prefer to copy from another part of the image and then click done.

Cannot use Create method with SODataEntity in iOS Native Apps connect to SMP 3.0 SP05

Hi experts,
I am following these blogs:Mobile Application Development Platform for Developers - Native Apps. They are very helpful, thanks Kenichi.
But i have some error when i use Integration gateway.
First, i try method Read, it works perfectly. Then, i try to use method Create, and i meet an error. Here is the error :
Error Domain=NetworkDomain Code=4 "HTTP Response: 403 forbidden" UserInfo=0x7f86d2688040 {NSLocalizedDescription=HTTP Response: 403 forbidden}
I test CRUD method in REST client, and it runs without any errors. I think the difference between Create and Read method is "X-CSRF-Token": Fetch with Read and specific Token with Create. But i do not know how to supply or config "X-CSRF-Token" field when use SOData...
Thanks and Reagrads,
Sao Vu.

Hi Sao,
Is your problem solved?
If not, below code may be able to help you for creation using ODataStore:
MAFLogonRegistrationData *data = [[MyLogonHandler shared].logonManager registrationDataWithError:&error];
    NSString *baseURL = [NSString stringWithFormat:@"%@", data.applicationEndpointURL];
    //opening the store
    self.onlineStore = [[OnlineStore alloc] initWithURL:[NSURL URLWithString:baseURL]
                                httpConversationManager:[MyLogonHandler shared].conversationManager];
    [self.onlineStore openStoreWithCompletion:^(BOOL success) {
//Read request after the store is successfully opened
        SODataRequestParamSingleDefault* readRequest = [[SODataRequestParamSingleDefault alloc] initWithMode:SODataRequestModeRead resourcePath:@"CollectionName"];
        [self.onlineStore scheduleRequest:readRequest delegate:self];
        NSString *finishedSubscription = [NSString stringWithFormat:@"com.sap.sdk.request.delegate.finished.%@", readRequest];
//Going for create once read request is success
        [[NSNotificationCenter defaultCenter] addObserverForName:finishedSubscription object:nil queue:[NSOperationQueue mainQueue] usingBlock:^(NSNotification *note) {
//Creating request for posting the data
SODataRequestParamSingleDefault* insertRequest = [[SODataRequestParamSingleDefault alloc] initWithMode:SODataRequestModeCreate resourcePath:@"CollectionName"];
            insertRequest.payload = entityForCreation; //Assigning the payload
            [self.onlineStore scheduleCreateEntity:entityForCreation collectionPath:@"Collection
Name" delegate:self options:nil];
//Alternatively you can use [self.onlineStore scheduleRequest:insertRequest delegate:self]; also instead of scheduleCreateEntity
If you want to pass X-CSRF-Token with RequestBuilder, you can use the following code:
//Create request for getting the token
      id<Requesting> request = [RequestBuilder requestWithURL:[NSURL URLWithString:[NSString stringWithFormat:endPoint_URL]]];
        /*Set user name */
        [request setUsername:[[NSUserDefaults standardUserDefaults] objectForKey:@"USERNAME"]];
        /*Set password */
        [request setPassword:[[NSUserDefaults standardUserDefaults] objectForKey:@"PASSWORD"]];
        /*Set the required request headers*/
        [request setRequestMethod:@"GET"];
        [odp_Request addRequestHeader:@"X-CSRF-Token" value:@"Fetch"];
        [odp_Request addRequestHeader:@"X-CSRF-Cookie" value:@"Fetch"];
        [request addRequestHeader:@"Content-Type" value:@"application/xml; charset=UTF-8"];
        [request addRequestHeader:@"X-SMP-APPCID" value:applicationConnectionID]];
        [request addRequestHeader:@"X-SUP-APPCID" value:applicationConnectionID]];
        /*Set the delegate to receive the response */
        [request setDelegate:self];
        /*Set the success listener */
        [request setDidFinishSelector:@selector(tokenSuccess:)];
        /*Set the failure listener */
        [request setDidFailSelector:@selector(tokenFailed:)];
        /*Invoke the startAsyncronous API to send the request from client to server asynchronously */
        [request startSynchronous];
//In the tokenSuccess method (- (void)tokenSuccess:(Request*)theRequest), you can use the following code to retrieve the token:
      token=[[theRequest responseHeaders]objectForKey:@"X-CSRF-TOKEN"];
       cookie=[[theRequest responseHeaders]objectForKey:@"SET-COOKIE"];
//Create the request for posting your content to the server
            NSString* requestUrls = [NSString stringWithFormat:@"%@SalesOrders%@", endPoint_URL,filterString];

Error extracting data from essbase cube using MDX method

Hi,
We have some problems extracting data from essbase cube using MDX method, we believe that the problem is the MDX query, this is the problem and query:
ERROR:
[DwgCmdExecutionThread]: Cannot perform cube view operation. Analytic Server Error(1260046): Unknown Member SELECTNON used in query
com.hyperion.odi.essbase.ODIEssbaseException: Cannot perform cube view operation. Analytic Server Error(1260046): Unknown Member SELECTNON used in query
at com.hyperion.odi.essbase.wrapper.EssbaseMdxDataIterator.init(Unknown Source)
MDX:

NON EMPTY {[Centros de Costo].[1101]} ON AXIS(6),
NON EMPTY {Descendants([Resultado Operacional],4)} ON AXIS(7)
FROM [DSR02].[ROP]
We try extract data using a sample cube and work fine, this is the mdx query:
SELECT
{[Actual],[Budget]} ON COLUMNS,
{[Sales]} ON ROWS,
NON EMPTY {[Product].levels(0).members} ON PAGES,
NON EMPTY {[East].levels(0).members} ON AXIS(3),
NON EMPTY {[Year].levels(0).members} ON AXIS(4)
FROM Sample.Basic
The model reversed ([DSR02].[ROP]) have the same structure than query need, the query and the model are fine, definitely we can´t see the problem, someone can help us?
Regards

You will be able to test the MDX query in EAS, it is usually best to test the query first before trying to use it in ODI.
Is there any reason you are using MDX to extract the data, have you tried reportscript as I usually find it more efficient to extract the data.
Cheers

Cannot use AV settings in Quicktime Pro

Hi the AV controls are greyed-out. I can use the editing features, but cannot use the brightness etc controls that are so handy. In control panel, I open the quicktime icon, it shows the key entered with no error mesages. One of my PC's works, the one I am trying to replace it with, does not. Anybody?

The A/V Controls window is not available to all computers (Mac or PC).
They depend on the graphics card installed on them.

My ipod does not recognize touch all of a sudden. It is on, but I cannot use it because it won't recognize my touch! Help please!

-You stated: " It is on, but I cannot use it "
Does this mean that the iPod works fine but when you connect the iPod to your computer iTunes does not see - your iPod?
- Have you tried:
iPhone, iPad, iPod touch: Device not recognized in iTunes for Mac OS X
- If you really have OSX 10.6.x (not 10.5.8 as stated) try:
Mac OS X v10.6 or later: iOS device not recognized in iTunes after restart
- Have you tried another cable and USB port?
- If the iPod is not working then there are other things to try.

X6 Headest - Cannot use my headset as a handsfree ...

Hello everyone!
From some reason I cannot use my headset (the ones that came with the X6) as a handfree kit.
I plug them in - choose Headset option - but cannot hear anything when someone calls me or when I call someone else. Am I missing something???
I haven't experienced any problems with the music player. When I choose the Headphones option to listen to music everything is noraml. However, I am not able to control the music (play/pause, fwd, next, sound) with the remote. Why is that???
Please help!
Thanx!

Yeah not that fast, but sometime when we plug-in the jack half way and then after a pause we push it down, phone doesn't understand what it is, and a pop-up comes up saying select Accessory. (At least from my experience)

Cannot use user classes in webservices interface of appmodule custom method

Hi,
I need to expose an application module's custom method that uses user defined classes as parameters and return types as a web service interface. I have not been able to do that. Below are more details.
In particular, I have an app module that has a client interface with a custom method that takes and returns a serializable Emp object (user defined classes/objects). I need to expose this app module as a web service through the use of a service interface.
When i run the "Create Service Interface" wizard, under service custom methods (Create Service Interface Step 2 of 4 wizard), i don't see my custom method under "Available."
In addition, the JDev message log says: Business Components: Method "yourCustomMethod(Emp):Emp" cannot be exposed via service interface because the return type "com.mypackage.Emp" is not supported.
From what i understand by reading the docs below, it seems that in an application module's service interface (Webservice) you only can use simple data type or java.util.list or AttributeList (which is a wrapper for any viewRow). In other words, i cannot use my user defined object in the custom method parameters and return types.
This seems to be an artificial limitation of webservice creation through the use of app module because one can use complex/user defined objects in methods of a java class and expose them through a webservice.
I would appreciate if of the tooling PMs can make a well thought out comment.

ps: I am using Build JDEVADF_11.1.1.5.0_GENERIC_110409.0025.6013.

Hi,
question 2 doesn't apply as the client interface is for Java access to public methods. For the Service Interface, the document lists the supported data types you can use in arguments and return values. To expose a custom methods, what about using a POJO that accesses ADF BC (using create root application module) and then expose your POJO as a JAWS service. This will allow you to expose the data queried from ADF BC through your custom classes.
