The usual ClassNotFound for stubs, but I cant remember

Hi guys. I have a problem with my rmi app. First of all
I have the server stuff in server package, the worker stuff in worker package, some essential code in source package and thats it. So the directory structure is
path/server, path/worker, path/source etc.
Although in the office machines it works fine, in the house I get
java.rmi.ServerException: RemoteException occurred in server thread; nested exception is:
     java.rmi.UnmarshalException: error unmarshalling arguments; nested exception is:
     java.lang.ClassNotFoundException: server.ServerImpl_Stub
but the stubs are there. I am in the root dir and doing javac server/*.java, javac worker/*.java etc
then rmic server.ServerImpl
and then java server/ServerStarter (server.ServerStarter doesnt make a difference)
Can somebody please help because I need to do a lot of work during the weekend. thx

This has been solved. The problem was that the stubs and main classes had to be compiled with the same Java version and rmiregistry started from the root project dir. thx

    Please follow these directions to delete the Mail "sandbox" folder.
    Back up all data.
    Triple-click the line below to select it:
    ~/Library/Containers/com.apple.mail
    Right-click or control-click the highlighted line and select
    Services ▹ Reveal
    from the contextual menu.* A Finder window should open with a folder named "com.apple.mail" selected. If it does, move the selected folder — not just its contents — to the Desktop. Leave the Finder window open for now.
    Quit and relaunch Mail, and test. If the problem is resolved, you may have to recreate some of your Mail settings. You can then delete the folder you moved and close the Finder window. If you still have the problem, quit Mail again and put the folder back where it was, overwriting the one that may have been created in its place. Post your results.
    Caution: If you change any of the contents of the sandbox, but leave the folder itself in place, Mail may crash or not launch at all. Deleting the whole sandbox will cause it to be rebuilt automatically.
    *If you don't see the contextual menu item, copy the selected text to the Clipboard (command-C). In the Finder, select
    Go ▹ Go to Folder...
    from the menu bar, paste into the box that opens (command-V). You won't see what you pasted because a line break is included. Press return.

    In your case your only solution is to restore it ( see http://support.apple.com/kb/HT1808 ) and you may need to force it into restore mode to do that.  This will wipe everything off it and reset it as new, without the passcode.  You can then redownload purchased content, buy unless you have a sync'd copy of your contacts and photo's they will be gone.

    You most likely did not receive the usual receipt because it was one of those authorization charges. It happens time to time, and should drop off your card. But go ahead and check with iTS just to make sure.

  • HT1386 i have an iphone 4s. Im getting the iphone 5s for christmas, but i do  not have my phone backed up, and my phone is not working and my screen is covered with blue lines. I need help.

    My iphone is not working, i was planning on getting the iphone 5s for christmas, but i do not have my phone backed up on itunes. On my screen are these blue lines across on my screen, and i cant see anthing and i do not know what to do. I want to back up my phone but i cant see my screen to back it up. I need help badly. Thanks apple hope you can help me in this matter.

    You wouldn't need to see the screen to backup unless you have a passcode on the device. Is that the case? You should be able to plug the device into the computer with iTunes and just select backup now.

  • I have a mac  book pro that i bought in late 2009. My current software is snow leopard version 10.5.8. I would like to get the new lion operating system but I cant without first getting the latest version of snow leopard. it doesnt show on software updat

    I have a mac book pro that i bought in late 2009. My current software is snow leopard version 10.5.8. I would like to get the new lion operating system but I cant without first getting the latest version of snow leopard. however when I go to update my software it doesnt show that any update is available.

    10.5.8 is Leopard, not Snow Leopard. You need the Snow Leopard DVD;
    You can get it only by phone now from Apple.
    In the US, call 1-800-MY-APPLE and ask for a sales assistant. Last quoted price was $19.99 for the single-user and $29.99 for the family licence.
    For other countries, check here; http://support.apple.com/kb/HE57
    Don't forget to ask for Sales; the tech support guys can't help.
    If you want Lion, rather than Mountain Lion, the same Sales team can give you a download code to use at the Mac AppStore.
    To get the App Store, you need to update your new Snow Leopard from 10.6.3 (which is the version on the installer) to 10.6.8 with the combo update; http://support.apple.com/kb/DL1399
    Be warned that the upgrades will render a lot of older software unusable, and will need new drivers for printers and scanners in all likelihood.

  • I cant connect to wifi but my laptop can and my other phones can.ived done all the recommendations in ipad support but still cant connect..what else shall i do?

    i cant connect to wifi but my laptop can and my other phones can.ived done all the recommendations in ipad support but still cant connect..what else shall i do?

    Some things to try first:
    1. Turn Off your iPad. Then turn Off (disconnect power cord for 30 seconds or longer) the wireless router & then back On. Now boot your iPad. Hopefully it will see the WiFi.
    2. Go to Settings>Wi-Fi and turn Off. Then while at Settings>Wi-Fi, turn back On and chose a Network.
    3. Change the channel on your wireless router (Auto or Channel 6 is best). Instructions at http://macintoshhowto.com/advanced/how-to-get-a-good-range-on-your-wireless-netw ork.html
    4. Go into your router security settings and change from WEP to WPA with AES.
    5.  Renew IP Address: (especially if you are droping internet connection)
        •    Launch Settings app
        •    Tap on Wi-Fi
        •    Tap on the blue arrow of the Wi-Fi network that you connect to from the list
        •    In the window that opens, tap on the Renew Lease button

  • Re: DW CC The usual choices for the Workspace Layout are missing. How can I restore them?

    The usual choices for the Workspace Layout are missing. How can I restore them?The usual choices for the Workspace Layout are missing. How can I restore them?

    The Insert panel has been reworked pretty significantly in DWCC (Spry has been dead for over a year now, so it no longer appears for instance), but can still be opened via Window > Insert then dragged to the toolbar location (to get the tabs back) by clicking and dragging the Insert tab up to the top of the application frame until it highlights. Once you drop it, it will then appear as a toolbar.
    Not all of the tools will be visible at all times. DWCC knows when certain things can't technically be used and it won't display them if they can't be inserted.
    EDIT: Oops, forgot to add this. Here is a link talking about what has changed in the Insert panel: http://helpx.adobe.com/dreamweaver/using/changes-insert-options-creative-cloud.html

  • Bought an iPod nano for use in an external source to the unit of the BMW. It works, but don't remember the place when you turn off the power and every time begins to play the playlist first.

    Bought an iPod nano for use in an external source to the unit of the BMW. It works, but don't remember the place when you turn off the power and every time begins to play the playlist first.

    Thanks iPod Whisperer--
    I do realize that the nano will resume where I left off in my audiobook if I reload the file that was last playing.
    What I was hoping is that the 6g nano would work like my previous iPods and default to the last file played the next time played after Iused sleep mode instead of going to some random song on the iPod.
    Since I usually have a lot of audiobooks on my iPod--and most of those have 10-15 files in them, it's a pain to have to navigate to the correct file (and try to remember which of the 10-15 files I was last playing). On all my other iPods I could simply hit play and it would start up in the audiobook right where it left off.
    Note--this only happens if I use the sleep timer to turn off the iPod. If I pause the book myself, when I turn the iPod back on it'll "remember" what file it was playing.
    Hope this makes sense.
