Shared Blackboard!! HELP!!

Hi
I have to integrate a shared blackboard module in my java application, anyone knows about it? Are there any shared blackboard implement for Java made?
Thanks

Do a search for
JSDT
or
JXTA
in
http://www.java.net/
and
http://www.jxta.org/
Both of these technologies provide Collaboration frameworks
JSDT is an older technology (& has not been well supported by SUN - it is now Open Source)
JXTA is a recent new specification for P2P

  • Report sharing problem - Help!

    I have developed a CR XI report template linked to a Salesforce database. Runs fine. I sent a copy of the .rpt file to a colleague who is using the same version of CR XI (both copies are legal and registered). When she tries to open the .rpt file, she receives an error message saying that CR doesn't recognize the file format. We've tried several times. I sent her a blank non-SF .rpt file ... same problem. She sent me a blank non-SF linked template from her system. I can open it just fine, but if I make ANY changes and return it, she gets the same error message whether she's linked to SF or not.
    Product Version: 11.5.8.826
    What's the cause? We need to be able to share report templates smoothly and I assume that this is possible 'cause it appears to work in one direction.
    Thanks,

    Not sure if this will help you, but I had a similar issue and wanted to post my solution somewhere on these forums for others to reference.
    My PC with iTunes has the my entire music library and I was trying to share it to my Mac Mini wirelessly, and couldn't get it to connect. The Mac could see the PC listed under the Shared section, but I would always get the error you received.
    Here's what I did: I went to the Disk Utility (under /Applications/Utilities/Disk Utility
    I then clicked on my hard drive, and under First Aid, selected 'Verify Disk Permissions'. I noticed that a couple of files with the word iTunes in the name were not correct - I ran the 'Repair Disk Permissions', opened iTunes, and sharing worked immediately.
    I hope someone else can benefit from this....

  • Family Sharing Setup Help

    Hi all,
    My wife and I have an old iCloud/iTunes account setup that we like but it doesn't want to play ball with Family Sharing.  Consequently, I am hoping you guys can help us nut out the next steps.
    Before Family Sharing, my wife and I wanted to share photos, contacts, calendar events, shared email and so forth but be able to make our own iTunes purchases separately.
    Consequently, we set up an iCloud account and put this into both of our iPhones, laptops and iPads under Settings > iCloud.
    We still, however, had iTunes Store, FaceTime, Messages etc set up on individual Apple ID's.
    I attempted to set up Family Sharing using the shared iCloud account and setting my personal iTunes Apple ID as the "purchasing" authority and payment.
    However, when I invited my wife in - it shows exactly as it is set up (probably due to the shared iCloud account details) and she doesn't see any purchases I have made and I don't see any purchases she has made.
    What should we now do?  Do we need to revert to using our own individual Apple ID's in "iCloud" or something?

    Hello Carney10,
    Thank you for visiting Apple Support Communities.
    When you say you do not have the setup option for Family Sharing, that seems like you log into the iCloud System Preference but the "Set Up Family" button is not there.
    Is your Mac updated to Yosemite?
    Family Sharing - Apple Support
    iOS 8 and OS X Yosemite are required to set up or join a Family Sharing group and are recommended for full functionality.
    Where in the setup are the options not available or working?

  • HT202213 I am told that I have authorized 5 computers already (this is my first time) and I have to deauthorize this computer inorder to get home sharing. Help! this makes no sense. What a pain Apple tv is.

    I have almost never used my appe tv--passwords and id get so confusing--it makes me tierd and I give up and walk away. But now I need to use my Home Sharing feature and am told by iTunes that I can only authorize 5 computers to do this and according to their count, I have already done 5. I have only two computers so I know this is not correct. But what can I do about it? I am told by a pop up that I should deauthorize this computer--the only one I want to use for this project--it makes no sense to me. This has already eaten up my day with reseting passwords, ids etc. I'm almost ready to throw Apple TV out. This $100.00 object has already eaten up more than $100.00 of my time! Help.

    Simply deauthorize all, then authorize your computer.

  • Printer Sharing: Need Help!

    Hi, I use an iBook G4 connected via Airport to a Windows PC. I have a dsl connection on windows and so I surf the net with my iBook with my wireless card. I also shared my HP3420 to be able to print files with my iBook but always I recive an error message... Could anybody help me? I think that windows is configurated (right click / share printer / printer's name); On the Mac I have to choose 3 different protocols and the only thing that appears to be correct is the address of the remote computer (win). Any advices? Thanks a lot for your support!

    Go to the Printing & Faxing Discussions in OS X and read about the problems with sharing a Windows printer. There are some links posted for possible solutions.

  • Personal File Sharing Quits - Help!  I have a deadline!!

    I'm having problems with personal file sharing. I have two macs, both dual 2GHz G5s. Computer 1 has all of the work files on it, and when computer 2 tries to connect, it shuts down personal file sharing! Computer 1 can connect to computer 2, but not the other way around.
    Can someone please help. As usual I have a deadline and I need this solved asap.
    Thanks
    PS. I'm using os x v10.4.6 Which I installed yesterday. After I installed that update, file sharing worked fine. Now, after I restarted again today, suddenly file sharing keeps shutting down.

    I seem to have got it working again. I used a program called Xupport to repair the permissions and do some other system maintenance, and now everything is working again.
    carry on...

  • Shared Variable Help

    Hey,
    I need some help with shared variables. Here is what I'm trying to do. I run a vi on the computer that uses a camera to track certain objects. I would like this program to send the position of the object to another vi that is running at the same time on the speedy-33. The speedy-33 takes the position and rotates the robot towards the object. The problem I have is communicating the position from the computer to the speedy-33.
    From what I've read, I think I'm supposed to do this with shared variables. On the computer target,  I created a library with an integer variable (to hold the x position of the object). I set this variable in the computer vi using the shared variable. All of this is in a while loop. On the speedy-33 VI, I've connected a control to the shared variable. When I run the program everything works as intended so far. When the object's x value changes the control on the speedy-33 front panel changes appropriately. However, when I try to drag the variable onto the speedy-33's block diagram from the project explorer I get a bunch of errors. The first is "My Computer\Variables.lvlib\xpos: Not supported for current target." Since it appears this isn't supported for the speedy-33 how am I supposed to transfer the data?
    Hope all that makes sense.
    Thanks

    Well, I for one got lost somewhere in there. Didn't you say that you already had the shared variable in both the computer VI and the Speedy-33?
    It may be a good idea to take a look at the Shared Variable Client-Server example, and perhaps test it to see if it, at least, can work on your setup.
    I for one gave up on shared variables (flow control was just too much trouble) and am using "functional globals" instead. http://zone.ni.com/devzone/cda/epd/p/id/4364 was particularly helpful.Message Edited by kehander on 02-20-2007 12:46 PM

  • HT201454 I systemically tried every suggestion on Apple's "If you don't see your family's shared content" help page. None worked. Does anyone have a solution?

    My wife and I are set up for family sharing, but neither OS X nor iOS app store purchases appear to be sharing (i.e. the App doesn't just say "Get" for the other person after it is bought by the partner). Apple's suggestions did not work. Does anyone have a solution to this?

    I solved my own problem but I don't think this is how Family Sharing is meant to work. On my Mac, I purchased an app. On my wife's mac, when I search for that app in the store, it has a button with a price on it (not a cloud symbol or anything that would indicate it had already been purchased by someone in Family Sharing). HOWEVER, when I click on the "Purchases" button at the top of the app store, use the pull down menu to change to the other member of the family, then all the apps can be installed.
    I thought sharing would mean that the apps would be free from their normal site in the app store. If you have to go to purchases to see apps purchased by the family, then you might miss that fact and double pay. Perhaps Apple did this on purpose to help its app developers make more money despite Family Sharing.

  • More shared variable help

    Yep, I'm attempting a large shared variable project, so, I guess it's time to get active on the board again. 
    Anyway, so I had this problem;
    http://forums.ni.com/t5/LabVIEW/Getting-a-list-shared-variable-references/td-p/1817829
    but we got that figured out. 
    Now, when I go to write the data to the variables, I can watch it go from 'No Known Value' in the distributed system manager to '     ', and yes, I mean blank. Granted, the data is coming from a simulated DAQ currently, but I can probe the data line in the .vi and there's numbers there, they're just not getting to the shared variable. Any ideas as to what I'm doing wrong? I've got the variables deployed and the shared variable engine is running on the computer. Is there something I need to do programmatically prior to writing to them? 
    Here's the snippet so you don't have to switch between tabs to look at it,
    Thanks for any help,

    Solved!
    Go to Solution.

    Hi Ian,
    It is hard to tell exactly how the data will display when pulling from a citadel database. One recommendation I have for you is to use the Read Trace/Write Trace .vi's which will allow you to break up the waveform and handle the data apart from the timestamps they are associated with.
    Hope this helps!

  • Shared Directory Help

    I accidentally deleted the information in the shared directory pages that displays the directory listings and what is in them (just the default out of the box oracle codes).
    I am a mid/expert portal user but a novice SQL user so I have NO clue how to get it back. Does anyone know if I can do a partial restore of this information or what snippet of code I deleted that caused the removal of the file indexing?
    I believe the code was located in the navigation banner (it was the only thing I changed before I realized it was gone)
    For now, I have the HTML code from the wireless devices hanging out there ( for A it is :
    a... ( Where MODE =23 = wireless (I don't know what it is for NOT wireless or if it was more sophisticated than HTML before)
    But obviously, if someone clicks on one of the above links, they get the wireless shared directories information instead of the correct share document information which is way no good.
    Any help or insight you all could provide would be extremely helpful

  • CP7 Shared Actions Help needed

    Hi folks.
    Looking for some help with something I'm trying to do with the new cool Shared Actions.
    First of all here is the Set up!
    What i am trying to achieve is to test if a person has followed a decision tree correctly.
    The tree will take them eventually to one of 3 possible outcomes and each person who follows the tree will be looking at a unique set of circumstances so I can't say for any of the individual choices on the tree if it is correct or wrong.
    Each choice they make is set up as a slide with a yes or no button.
    As they click yes or no I am taking them to the appropriate next decision on the tree.
    At some point they will reach a 'final' slide that tells them they should be ready to choose between the 3 possible outcomes. 'Create'  'Keep' or 'Dismiss' and offers those choices.
    I actually built 3 identical versions of this slide. I built them as MC questions so that for each of the options I can have a right answer that I can feed back to my LMS to tell me that the learner has made the correct decision.I made sure that the quiz is Branch Aware so as the user will only be presented with one question (based on the choices they took on the tree) they will either score 100% or 0%.
    I managed to do all this successfully using advanced actions.
    For each button that took me to the 'final question' slide I had to write a specific advanced action that moved a feedback message to a message variable (using an assign) and then jumped to the appropriate final question slide.
    The problem for this is that it is a specific advanced action for each slide that could take them to the final slide. And there are several in this project. and i will need to do the same thing for maybe a dozen other projects.
    So I tried to set these up as advanced actions.
    I had hoped to be able to have the variable and the target page as parameters.
    But what I cannot seem to do is have the variable as one of the parameters.
    Have I missed something about Shared Actions or is this a limitation.
    Or can someone think of a better way to achieve what I'm aiming for.
    Thanks
    Alan

    And we also need to be able to execute Advanced Actions and Conditional Advanced Actions from within other Advanced Actions or Conditional Advanced Actions.  That would give us something similar to programming functions in normal code.  But it would potentially create all manner if issues with endless loops.  So Cp will need some way of detecting unsafe conditions that could break the published output.  Something it's never been very good at doing in the past.

  • HT202213 I have only allowed two playlists to be home shared but my whole library is being shared? Help?

    I am setting up Home Sharing on my kids computers and on my computer have selected to only share their playlists. However on one of my kids computers it is showing the entire library.
    Can anyone help?

    The way home sharing works is your entire library is shared. You can consider Windows sharing options If you put music in your public folder on Windows, your kids will access those files and be able to drag those over and import in itunes.

  • ITunes 11.0.2 will not allow me to drag any files to import items between computers using Home Sharing. Help?

    There are no "import" thumbnails and I'm un able to drag and drop files. I've ensured on both computers that they both have sharing capabilities. All the websites say that I should be able to just drag and drop the files into the outgoing computer linked to my homesharing network, but there is not reaction from the file when i try to grab it.Thanks everyone!

    I can not find the "Show menu" button either!    I am trying to do Home Sharing between 2 PCs in the same room.  The Home Sharing Libraries show up ok on each, with the various tunes displaying on each, but I can not move (or "import") tunes from one computer to the other!   It also won't allow me to drag from my husband's library to my library, and vice versa.    I can play them ok on each computer, but the dragging or importing is not happening.
    Apple, please fix this!   Both PCs are up to date with iTunes 11.0.2.26.
    Anyone have any suggestions?   I just want to move legally purchased music from one computer to the other.  This shouldn't be that difficult.     It's supposed to be the point of Home Sharing!
