Warning: [unchecked] unchecked call to getMethod when updating to JDK 1.6

I'm received the following compilation warnings after I switched to Java 6 from Java 5:
warning: [unchecked] unchecked call to getMethod(java.lang.String, java.lang.Class<?>...> as a member of the raw type java.lang.Class
removeChangeListener = myParent.getMethod("removeChangeListener",
changeListenerParameterTypes);
The code is this class is instantiated by many classes. The class instantiating this class is passed through a constructor.
Here is a partial code snippet of the class, constructor and method where the warning occurs:
public class DumpDisplay extends javax.swing.JFrame implements javax.swing.event.ChangeListener
private Class changeListenerParameterTypes[] = new Class[2];
public DumpDisplay(Object mvc)
Class myParent = mvc.getClass();
public void removeListeners()
Method removeChangeListener = null;
changeListenerParameterTypes[0] = ChangeListener.class;
changeListenerParameterTypes[1] = Integer.TYPE;
// Get the removeChangeListener method from the MVC class
try
removeChangeListener = myParent.getMethod("removeChangeListener",
changeListenerParameterTypes);
catch (NoSuchMethodException e)
System.out.println(" DumpDisplay class addChangeListener method: "+e);
This compilation warning does not appear in JDK 1.5. Any assistance is greatly appreciated.

Class myParent = mvc.getClass();Class<?> myParent = mvc.getClass();

  • Warning about unchecked call

    What does it mean?
    warning: [unchecked] unchecked call to add(E) as a member of the raw type java.util.Vector properties.add(prop);
    and how can I avoid this warning? what shall i check?

    If you use -Xlint, it will tell you the line number.
    Basically, though, you are compiling in j2se 1.5.0, but not specifying the type for the Vector. That is, you are using it in it's pre 1.5.0, raw mode, and it cannot do any compile time type checking for you.
    Say you were using your vector to store Integers. You would declare it as Vector<Integer> myIntegerVector = new Vector<Integer>();and the warning would go away. Now the compiler can do compile time type checking, and let you know when you are using that vector with a type other than Integer, which might not be safe.

    copy.path = (Vector<Long>) this.path.clone();The variable path has a type of Vector but clone() returns an Object. It is only a warning, not an error, so you can ignore it - I think you can be confident that clone() will always return a Vector. A slightly more typesafe approach (in my opinion) is to create a new Vector<Long> using the constructor that takes a Collection as an argument, passing in the Vector that you want to clone. Something like
    copy.path = new Vector<Long>(this.path);

  • Warning: [unchecked] unchecked cast.

    Hello!
    I have a problem with this code.
    I get:
    warning: [unchecked] unchecked cast.
    How should i do the cast?
    Or is it something else that i have done wrong?
    Socket socket = new Socket("localhost", this.port); 
    LinkedList<String> times = new LinkedList<String>();
    ObjectInputStream ois = new ObjectInputStream(socket.getInputStream());
    try
        times = (LinkedList<String>)ois.readObject();
    catch(ClassNotFoundException cnfe)
    }

    That's because it is not 100% sure (at compile time) that the object is really of a type LinkedList<String>, that's why you received a warning (note that this is just a warning: not an exception or error). You cannot do anything about is. You could suppress the warning like this:
        @SuppressWarnings("unchecked")
        void yourMethod() {
            try {
                Socket socket = new Socket("localhost", 666); 
                LinkedList<String> times = new LinkedList<String>();
                ObjectInputStream ois = new ObjectInputStream(socket.getInputStream());
                times = (LinkedList<String>)ois.readObject();

  • Error when updating! Help please!!

    I've been having a problem with the artwork updating on my 5th iPod. I kept getting an error when updating in iTunes whenever I added artwork to songs. So I was told to go into iTunes and go under iPod options and UNCHECK the box to display the artwork on my iPod. Then click okay. Then, go back into it and CHECK the box TO display the artwork and I get an error; "..Unknown Error occurred (-50)". Same error. And yes I have pressed the center button on my iPod to scroll through the different things. And I have restarted the program and computer. Tried disconnecting hte iPod, closing the program, restarting computer, restarting iTunes and reconnecting iPod and every combination of the steps (I've done many searches on this subject here) and same result. I've tried other different things but it all ends up to this error. Can some one please help me

  • Descriptor query manager and custom PL/SQL call for the data update

    hi all,
    in the application, I'm currently working on, the operations for the data INSERT/UPDATE /DELETE are allowed only by means of PL/SQL function. Using the descriptor's query manager I'm trying to modify default behavior of TopLink and execute PL/SQL when there is a request to modify the data.
    DescriptorQueryManager entityQueryManager = session.getClassDescriptor(MyEntity.class).getQueryManager();
    StoredFunctionCall call = new StoredFunctionCall();
    call.setUsesBinding(true);
    call.setProcedureName("merge_record");
    call.setResult("id", Integer.class);
    call.addNamedArgument("cbic_id", "id"); // MyEntity.getId() – works!
    call.addNamedArgument("publication_flag", "publicationFlag"); // MyEntity.getPublicationFlag () – works!
    call.addNamedArgument("routing_id", "routing"); // MyEntity.getRouring() – works!
    call.addNamedArgument("issue_id", "issue"); // MyEntity.getIssue() – works!
    call.addNamedArgument("country_id", "country"); // MyEntity.getCountry() – works!
    entityQueryManager.setInsertCall(call);
    entityQueryManager.setUpdateCall(call);
    entityQueryManager.setDeleteCall(call);
    the problem:
    when I call: MyEntity savedObject = (MyEntity) UnitOfWork.deepMergeClone(entity);
    the binding doesn’t happen and I see following logs:
    [TopLink Finest]: 2008.02.01 02:51:41.534--UnitOfWork(22937783)--Thread(Thread[AWT-EventQueue-0,6,main])--Merge clone xxx.Entity[id=2000]

    bind => [=> id, null, null, null, null, null] – WHY?
    Calling straight forward the same PL/SQL block using:
    DataModifyQuery updateQuery = new DataModifyQuery();
    updateQuery.setCall(call);
    updateQuery.shouldBindAllParameters();
    and passing parameters as Vector works very well.
    Could you please help me to fix the binding problem when I’m using the PL/SQL with Query Manager?
    regards,

    Hello,
    This is fairly common. Since the database is case insensitive (mostly) field names passed in don't really matter much. Unfortunately, java string comparisons are case sensitive, so if you db column for the getId() property is defined as uppercase "ID" it will not match to the lower case "id" defined in the
    call.addNamedArgument("cbic_id", "id");
    This will cause TopLink to get null when it looks for the "id" field in the row it builds from your MyEntity instance.
    Matching the case exactly will resolve the issue.
    Best Regards,
    Chris

    you might have selected given lowercase data
    and please check in the Infoobject the lowercase Checkbox is unchecked then it will allow you to update from IP.
    also check in the Datasource fields tab whether particular field is unchecked with lowercase.
    if checked all records you are pushing will have to be in uppercase.

  • Why is Google chrome installated when updating Flash?

    I think users can decide for themselves which browser they prefer to use.  We do not need Adobe to automatically install Google Chrome when updating Flash.  While there is an option to uncheck if you install from the Website, there is no choice when updating.
    We don't need this Big Brother, we know best attitude.

    I NEVER use the "updater" because I already have all the software I want and need. Use the "offline" FULL installers:
    Flash Player for ActiveX (Internet Explorer)
    Flash Player Plug-in (All other browsers)
    NOTHING in those but Flash Player.

  • Music does not sync properly when updated to latest version.  Can see computer but can't play from ipod

    Music does not sync properly when updated to latest version.  Can see on computer but can't play from ipod.

    Hope this helps...
    I was having the same problem where only 1.7GB of 10GB of selected music would sync so I decided to start fresh.  The following steps worked for me:
    1.  Open itunes and connect iphone 5 if not already.  Uncheck all playlists, artists, etc. till nothing is checked to sync.  Then uncheck the sync music box so that all music will be removed from the phone.  Sync iphone
    2.  Eject device. Quit itunes (don't just close). unplug iphone.
    3.  Restart imac, macbook, or PC.
    4.  Restart iphone.
    5.  Now after power up, restart itunes then plug in iphone, check sync music and select music to sync.  Sync iphone
    6.  It worked for me!!!  Good luck.

  • Support problem. The adviser tried to diagnose the failure of an application called JOTNOT PRO to update. He said he'd phone back at 8pm. I pick up his call at 8pm. Electronic voice: thank you for calling apple. We are now closed" So now I have 2 problems

    Support problem. The adviser tried to diagnose the failure of an application called JOTNOT PRO to update. He said he'd phone back at 8pm. I pick up his call at 8pm. Electronic voice: thank you for calling apple. We are now closed" So now I have 2 problems: the adviser had got me to reset so bye bye wifi passwords and settings. And then when he phones back as we agreed he's not actually on the phone, it's just a voice saying Apple Support is now closed! What on earth is going on at apple support I wonder.
    Anyway, the original problem: an application called JotNot Pro fails to update. The error message says something like "you cannot update this cos either you bought it with a different Apple ID or somebody else bought it."
    Neither applies. Can anybody help?
    PS. This is my first approach to the support community so please bear with me!

    You might have better luck contacting the app's support or developers.

  • On my iPhone 4, people cant hear me when I make and / or receive normal (GSM) phone calls. But when on calls using internet based / native apps like viber or skype, people can hear me just fine. Voice memos work too and have already tried different SIMs

    On my iPhone 4, people cant hear me when I make and / or receive normal (GSM) phone calls. But when I make/receive calls using internet-based / native apps like viber or skype, people can hear me just fine. I have tried recording my voice using voice memos - this works. And have already tried different SIM cards but the problem persists.
    I have taken my phone to an authorized Apple service center, where they restored my phone to factory settings, but still facing the same issue. They service center directed me to Apple Customer Care Hotline, where I have now spent 3+ hours explaining my issue and yet no one can resolve it. The easy answer if to replace the phone - and since it is out of warranty, I am expected to pay for it.
    Additionally, the customer service has been so rude and confrontational that it has completely changed my view of Apple and its customer focus. I am a disappointed and angry customer today - people would be surprised to hear just how rude customer service was including making statements such as "Apple doesnt make infallible products, that's why warranty is needed for our products" and that "every product undergoes a problem at some stage, so do ours!" There goes whatever confidence I had...
    My concern is simple - if no one at Apple and / or its CS hotline is able to address my issue comprhensively and keep telling me that they have never encountered a precedent before, then with what right can they expect me to pay for a replacement?! I am NOT here to fund Apple's research into their product faults and manufacturing.
    And even though a customer is out of warranty, is it too much to expect an Apple product to work well for at least a 'reasonable' period of time. My phone is less than 18 months old and has been facing this issue for the past 2 months - surely the longevity of Apple products is more than 18 months!
    Just a sad sad day for an Apple customer, compounded by unjustifiably rude and aggressive staff. And still no resolution to my problem.

    I am having the same issue - with my last 2 iPhone 4's. My first handset each time I was on a call wether it was up to my ear or on loud speaker, the call would automatically mute even though the mute button wouldn't show up as highlighted. Pressing the mute button on and off during the call doesn't fix it either. I rang Apple and asked what some of their trouble shooting solutions were. I got told that it might be a software issue and to install the latest software update. This failed. I then got told to uninstall the software on the phone and do a complete restore. This also failed. After trying the troubleshooting suggestions, I took the phone into my provider and they sent me out a new phone within a week under warranty claiming it was a hardware issue and probably just a "glitch" with that particular phone. This was not the case....
    After receiving my second iPhone 4, I was hopeful that it would work. For the first couple of days, making/receiving calls was not an issue. Until after about a week, the same problem started again. In one instance I had to hang up and call back 4 times and the call would still automatically mute after about 5 seconds. Also on the second handset, the main camera located on the back of the phone has red and blue lines running through it and can't take a decent picture. So back to the store I go to get another replacement - Again.
    For a phone that is rated highly and as a keen Apple product purchaser, I am a bit disappointed with the experience I have had with the iPhone 4. Let's hope they find a fix sometime soon because this is becoming a bit beyond a joke.....!!
