Can users drag any java objects in their browsers?

Hello,
I want to write a web page with Java technologies.
Users can only use Browers to use our applying services.
They can drag any Java objects on their browsers.
I only think to solve this problem with Java Applet.
(Users can drag any Java objects of Java Applet.
Webpages include Java Applet.)
Can any Java technologies do like this?
Can JavaBeans, Java Servlet, or EJB do so?
Thanks.

You may be able to do this with JavaScript and DHTML though when you do something this complicated it tends to get browser specific.
Stuff like javabeans etc. are just programming methodologies (and library routines), they don't really provide new capabilities. When you get down to it there's just servlets and applets.

  • I am running 10.5.8, and just updated my java to java 5 update10. Now my firefox is missing the Java plugin, and I can't load any Java applet at all. When I try it with Safari, it hangs when certain Java applet loads. HELP!!!

    Suddenly my Java plugin is missing and i can't load any Java with Firefox at all, even though i have it enabled in the browser! i've tried loading in java embedding plugin, but it doesn't work. what should i do???

    It's not in Tools> Add-ons >plugins?  Should be Java Plug-in 2 for NPAPI browsers 13.5.0. What are you seeing there? I don't think it's called the embedding plugin any longer.
    Might try getting the Firefox 5 standalone application. Trash the current one and replace it. Doing this won't affect your Profile or any settings.

    If it's enabled, how can it be missing?
    If this doesn't work, ask here. No need to register. Make sure you put (Mac) in the title.

    EDIT. Oops, may be different for 10.5.8. Was thinking recent Java update for 10.6. But try installing a new app anyway. In the past, this got me the latest Java plugin.

  • Can't drag any files from iTunes

    Suddenly, I can't drag any of the songs in my library in iTunes to my iPod, to other playlists, or to anywhere. When I try to click and drag, the file doesn't stick to the cursor. It just stays put. I am using the latest version of iTunes on the lastest system 10. Any ideas?
    Thanks.

    Sounds like a permissions problem.

  • I can't drag any item into itunes, it seems locked

    i can't drag any item into itunes, it seems locked

    I found the problem. I have VMware fusion that is hosting Window XP on the iMac. When the fusion is running the CD player is not seen in OS. By quitting Fusion I can now insert a CD and the disk icon appears on the OS screen. Now I can bring up iTunes and import the audio and continue as before. The one exception is I cannot bring in a photo of the album cover as before I have to drag the photo out of iPhoto and onto the desk top. Then I can drag it into the artwork patch in the iTunes/ info window.

  • Is it Possible in JSF? Can anyone recommend any java Technology for this?

    I am doing Post Graduate Degree in Computer Science. This is my final semester and doing project work.
    Any body having idea about my requirment, help and guide to me
    My description and questions are as follows:
    Current Approach:
    PHP has been used to achieve the flexibility of creating custom images on-the-fly. Using this approach we were able to create a web-interface similar to the application client, where we could display links and get the exact look and feel of the application client.
    Drawback:
    This approach forces us to use two different technologies Java and PHP, since our system uses 'Java' accessing all the API's from PHP becomes a problem. while PHP provides a way to invoke any java method. It comes with a draw back, the method calls are little slow. This delay's are loading of web-page.
    Requirment:
    1. Creating custom images on various locations of the screen
    2. The Exact look and feel of the application map should be achieved
    3. Place elements and links correctly as in application-client reflect any changes
    4. Generation events on the Links and Elements
    5. Setting Backgroud images for different maps
    Questions:
    1. is it possible in JavaServer Faces (BETA)?
    2. If it is possible is JavaServer Faces(BETA) How to create custom images and create interfaces among them?
    3.Can anyone recommend any java Technology for doing this?
    Anybody having idea, help and guide me for doing my project

  • I can't drag any object with trackpad or mouse. Please Help

    Since yesterday, like a bolt out of the blue, mouse and trackpad stop working properly, in the sense that I cannot drag any object in my desktop or in any application neither with the mouse, neither with the tackpad. Moreover, when I lunch Mercury I get a massage stating that some Java routine cannot be opened and Azureus refuse to start. My computer use last version of leopard and all the updates available, last java upgrade included. Everything else seems to work properly. Any idea of what colud be wrong and what can I do ti solve this irritating issue? Thanks.

    I can't think where else to look for this gremlin...
    How well backed up are you and do you have a clone of your system prior to the drag & drop problem? If you do, I'd erase your internal and copy over the good clone. Or, restore from a previous date from Time Machine.
    If not, you ought to run off a SuperDuper clone now. (SD is free for cloning) Then, do an archive & install. After you have everything you need back, delete the volume with clone since it is corrupt and run a good clone from your trouble free system

  • How can I call a java object from Web dynpro ABAP application?

    I made Web dynpro ABAP application and posted it to SAP EP.
    For certain business purpose, we need to call external 3rd party java object using 3rd party's java api in Web dynpro application.
    Is there anybody who experienced this kind of java interface issue?
    I know Web dynpro Java environment can fully support this kind of requirement. but regarding Web dynpro ABAP, I couldn't find any clue for this.
    Any comment or suggestion would be greatly appreciated.
    Thanks,
    Raymond, ABAP Consultant

    if you have jco configured, then you can make calls to java api from ABAP .

  • How can I persist a Java object to the PCD via JNDI ?

    Hi,
    I'm trying to persist XML data on the PCD via JNDI. I'm using
    portal version 6.2.0.4.200408172051.
    I followed the instructions in the "Portal Runtime Technology 640"
    document.
    The example they showed was:
    import javax.naming.Context;
    Context context = PortalRegistry.getCentralConfigurationContext();
    Context applicationContext = context.lookup("MyAppName");
    It was possible to obtain 'applicationContext' in the above example by
    using:-
    Context context = PortalRegistry.getCentralConfigurationContext();
    String appName = request.getComponentContext().getApplicationName();
    Context applicationContext = (Context) context.lookup(appName);
    However, any attempt to bind, rebind an object (implementing IStreamSource)
    resulted in NamingExcptions. As did 'listBindings' and 'list' (see below).
    BeanWrapper d = new BeanWrapper("test input");
    applicationContext.rebind("PCD_LOOKUP_KEY", d);
    // where 'd' implements IStreamSource
    class BeanWrapper implements IStreamSource {
    String content = "balh";
    BeanWrapper(String s) {
    content = s;
    public InputStream getInputStream() throws IOException {
    ByteArrayInputStream bis = new ByteArrayInputStream(content.getBytes());
    return bis;
    } // getInputStream
    } // BeanWrapper
    I don't know what I've done wrong. I couldn't find any more documentation
    on this topic...
    Any help would be appreciated.
    cheers,
    Michael

    Hi Michael,
    here my comments to your questions:
    0.:[Michael says:]
    "So basically you're saying that under SP10 its not possible to store objects on the PCD ... ?"
    I want to clarify this:
    It is possible to store objects in the PCD in lower releases than SP10 (e.g. SP2). But due to the fact that PCD API is not public before SP10 you should not develop a SP2 iView that programmatically uses the PCD API and complain afterwards because some "tiny" things of it are not working in SP10. It might be that you have to adjust some parts of this SP2 iView.
    The kind of object that can be stored in the PCD depends on the fact if the objects have a corresponding object provider or not. If you want to store iViews, roles or one of the other commonly known portal objects you can do it because corresponding object provider (iViewservice, roleservice, etc.) are always available in a running portal.
    If you want to store objects (like your BeanWrapper class) then you should write a corresponding object provider (what I explained in my first reply).
    1.:[Michael asked:]
    Why does list and listBindings fail ? surely that should just
    list the existing bound objects ???
    Nothing was bound!
    Your code line
    applicationContext.rebind("PCD_LOOKUP_KEY", d);
    throws a NamingException because no object provider for class of object d was found.
    So I gess you did a lookup on  applicationContext.lookup( "PCD_LOOKUP_KEY" ) before you did the list/listBindings and because this
    context does not exist the corresponding "Name not found" exception was thrown?
    A list/listBinding on the applicationContext itself should work even if nothing was bound.
    2.:[Michael asked:]
    Is there not some kind of default object/object provider pair
    that can be used to store base types like Strings/Integers etc ?
    No. There are no default object providers for java string/integers. But for this case "persisting a string or integer value at any PCD context" the PCD offers another way to do it: Just create an additional attribute (of type STRING or INT) and persist the corresponding value in this attribute (of type IPcdAttribute - an extension of javax.naming.directory.Attribute )   
    The code for creating a pcd attribute looks e.g. like this:
    IPcdObjectFactory pcdObjFactory = ((IPcdGlService) PortalRuntime
                                                   .getRuntimeResources()
                                                   .getService(IPcdGlService.KEY))
                                                   .getPcdObjectFactory();
    IPcdAttribute newPcdAttr = pcdObjFactory.createPcdAttribute(     PcdAttributeValueType.STRING,
                                            "new_attrId" );     
    newPcdAttr.set(     0,
              "new_AttrValue" );
    ModificationItem mods[] = new ModificationItem[1];
    mods[0] = new ModificationItem(      DirContext.REPLACE_ATTRIBUTE,
                               (Attribute)newPcdAttr );
    pcdCtx.modifyAttributes(     "",
                        mods );
    Hope, that helps you!
    Regards,
    Jens

  • How to create a new user without any sample objects from any other user?

    Question as the title.
    I had the example dababase installed when I installed the Oracle database.
    Every time, when I create a new user, there will be some example objects coming
    with the new user.
    How can I remove these objects from the new user?
    Or, how can I create a new user without the example objects?
    Thanks in advance.

    I think the easiest way for you would be to use OEM.
    Just locate each object that you want to remove and right click->remove. Don't bother doing this for any indexes as these will be removed when you drop the corresponding tables.
    If you want to try command line through sqlplus then identify the objects you want to remove by selecting from the user_objects view while logged in as this user. This will give you the name and type of object. Then issue the relevant drop command.
    It's probably worth making sure you have a valid backup first, just in case things go wrong!

  • How can i delete an java object immediately?

    Is there any mechanism that delete an object immediately?
    I know I can delete an java object by GC mechanism, but it can not be effective immediately.
    is there any other solutions?
    thanks -:)

    And you did an internet search to try and find out how to delete Java from your computer? Well, this forum is for Java programmers, people who write programs using the Java language. Not for people who use those programs. But it was a good try.
    The easiest thing for you to do is just to leave Java on your computer. It won't do any harm (aside from taking up a bit of space on your disk) and if you go to a web site that contains an applet, it might even be useful. Maybe that's why you got the link in the first place.
    If you really want to get rid of it, then go into Control Panel and use Add and Remove Programs to do that. (It's called something else in Vista, I forget what, hope you didn't get stuck with that.) But I would still suggest leaving it on your computer.

  • 3000 usd reward for the one can provide me any JAVA card with AES

    Hello,
    i am quite desperate, i am trying to find 1000-2000 java cards (schlumberger or jcop) with AES enabled. Seems this cards are really hard to find, i got allready offers and samples but all of them without AES enabled.
    I am willing offer 3000 USD reward to the person can give me the right contact where i can get those cards (at least 1000 pices) till 25-th of September. I got allready one offer from sagem orga for jcop, but their delivery time is 4-6 weeks, so it must be some one have such qtty of cards fizicaly on hand ready to ship.
    Please contact me by PM or phone (+852-6723-9999) or post here your contact details and i am calling you back.
    Thanks and best regards,
    Razvan

    @clemson
    i also have offer from sagem orga, delivery time 4-6 weeks, the point is that my customer does not understand that it is just a question of luck to find some one with cards on stock, he wants his goods fast. I have told him from begining not to stick on one specific card, but he preferred using jcop. I got some jcop from an analphabet, 10K pcs, jcop41 and this analphabet promised us to deliver us version 2.3.1, but the cards he delivered to us were 2.2.1 and those do not have AES !!!
    This is the reason why i am offering this reward. Maybe some one knows some one who have stock of 1000-2000 pcs. Now my customer does not mind to use ANY JAVA CARD which have AES. He don't mind if those cards are from Oberthur, Nxp, Gemalto, Giesecke & Devrient, or other manufacturer. His requirements are: a) must be java card b)must have AES other features are not important.
    Reagards,
    Razvan

  • Can't drag and move objects

    Using the Selection tool, i can select any object, but i can't click hold and drag it to a different position, like i usually can. I can click on one sides, or corners, and scale it just fine. I can also select it, right click, transform, move, enter a value and move it, i just can't click and drag it.
    All layers are unlocked, all objects are unlocked. This must be some hidden lock feature that somehow got enabled.
    Any idea how to fix it lol?

    Nope, I did not.
    However, i just rebooted my computer, reopened the document, and the problem went away. So i guess it was just some sort of a glitch at the time, I had actually fully closed Illustrator prior to this post, then reopened, and it didn't fix it.
    I think there is some random stability issue with my machine, it has reared its ugly head before in other areas. I can't even print from adobe reader because the graphics come all garbled out :-/. I've yet to reinstall it.
    Thanks for the help though.
