I am following the Short Course Fundamentals of R

I am following the Short Course "Fundementals of RMI". I am using Windows98_2nd and J2SDK1.4.0. The url is : http://developer.java.sun.com/developer/onlineTraining/rmi/
Does anyone know if the sample code does work with Win98 and SDK1.4.0 or is there something I
should be aware of ? I keep recieving various error codes ie (cannot find 'rmiregistry' (or one of its components) Check to ensure the path and file name are correct and all libraries are available);
also java.rmi.NotBoundException: CalculatorService.
and
Trouble: java.rmi.ServerException: RemoteException occurred in server thread; nested exception:
java.rmi.Unmarshal Exception: error unmarshalling arguments; nested exception is:
java.lang.Class Not FoundException: CalculatorImpl_stub.
RMI is new to me. Please if you will advise me on above.
Thanks Mark.

Trouble: java.rmi.ServerException: RemoteException
occurred in server thread; nested exception:
java.rmi.Unmarshal Exception: error unmarshalling

java.lang.Class Not FoundException:
CalculatorImpl_stub.
This error occurred on my system in much the same way. I found that I had more than one copy of rmiregistry and that one in fact belonged to an Oracle for Win98 I have installed on my system. Guess what the Oracle version came first in the PATH! Since I've changed this everything has been OK

  • Macbook Pro Charger cord breaking/short despite my following the care process?

    Despite my following the care process this is my 2nd 85 Watt Magsafe adapter to go bad and has a short in the cord after the adapter. I ensured I kept the cord uncluttered / not tangled up in open area / wrap accordingly (manual on how to care for magesafe adapter) when not in use. At work I keep the adapter on the desk. I have had my computer for 3 years without issue with the exception of having to purchase an $80.00 adapter cord a year ago. Now I have to purchase another within a year & half time. This isn't right.
    Can some one provide insight on how to address this (replace without having to pay for another cord).
    I bought it from best buy. I will try and locate my reciept. 

    You probably need to replace the two-prong attachment with the three-prong extension cord, which should have been included with the charging cable.  That adds length, as well as grounding the adapter, which is safer anyway.

  • The SAP Press book collection The Supply Chain Fundamentals

    Hi. I can navigate sap fairly well. I can follow a Business Process or, Workflow - if it is already written out, i.e., a test script. I am wanting to increase my knowledge, to the point where I know my way around SAP (MM) better, way better. I cant afford the cost of the SAP Training courses. So, would The Supply Chain Fundamentals Collection of books from SAP Press be a good investment? Please offer any advice you may have.
    Thanks.

    Hi,
    Get "SAP MM - Functionality and Technical Configuration". This is a good investment and has a wide applicability across the SAP platform.
    Cheers !

  • How do I delete a song from my Itunes library? I follow the instructions and right click on the song and click delete from the drop down menu but, then it asks me if I am sure I want to hide this song in Iclouds? I dont even know what Iclouds is?!?! HELP!

    How do I delete a song from my Itunes music library? I follow the instructions and right click on the song and then select "delete" as specified and my info claims at that point it will ask if I want to send this song to my trash bin, but, instead, when I try to delete the song, I get another window asking "are you sure you want to hide this song in iCloud? I don't even know what iCloud is?!?!? I don't want iCloud and just want to get rid of old songs!!! HELP ME!!!

    Short answer:
    Click Hide Song(s), it is what you wanted to do...
    Long answer:
    iTunes in the Cloud is a feature of your iTunes store account that allows you to redownload or stream your past purchases. When you delete a purchased track that is downloaded to your computer (like the first one shown here) you are asked if you also want to hide the song from iCloud. This would remove it from the computer and also stop it showing up with the iCloud symbol as the other tracks from that album (which are not downloaded) do.
    If a track shows with the cloud symbol you can play (stream) it by double-clicking the title, or click the cloud symbol to download a local copy to your library. If you try to delete one of these tracks you get a slightly different message confirming that you want to hide the track. Clicking hide will remove the listing from the library and any other device that shows your past purchases.
    Should you want to retrieve any item hidden in this way at a later date use Store > View My Account > iTunes in the Cloud > Hidden Purchases > Manage.
    To hide all your previous purchases that are not downloaded to your computer use Edit > Preferences > Store and untick Show iTunes in the Cloud purchases.

  • What are the major situations  to go to the short dump in abap programming?

    What are the major situations  to go to the short dump in abap programming?

    Hi,
    The major situations that an ABAP Program can result a dumb are as follows...
    1) Poor coding i.e., if the data in the data base is less, then even a poor code can give you the result.  But when you transport the program into Production, then there the same program will give you a dump, resulting 'TIMED OUT' error.  So performance tunning is required for each and every program.
    2) while calling a function module.
    3) extracting of data into fields which are not type casted.
    4) in case of x/y value, one should check the value of 'y' should not be zero, else a dump will result.
    these are few which i can give for time being........

  • I followed the same procedure of reverse calculation from MRP pricing calcu

    hi,
    sap gurus,
    i followed the same procedure of mrp calculation but
    MRP Pricing Procedure:
    Go through the following:
    I will brief your requirement in short
    MRP = 1012.5/-
    VAT = (1012.5/1.125) = 900/-
    so price before discount will be = 900/-
    discount given at the rate of 10% = 100/-
    Initial Price = 1000/-.
    1. Create condition types as below:
    ZR00 for price
    Condition class = B
    Calculation type = C
    Plus/minus = A
    ZSET for settlement (to knock off the effect of ZR00)
    Condition class = A
    Calculation type = C
    Plus/minus = X
    ZWST for tax
    Condition class = A
    Calculation type = H
    Condition category = D
    Plus/minus = X
    Z007 for discount
    Condition class = A
    Calculation type = H
    Plus/minus = A
    ZDUM for net price
    Condition class = A
    Calculation type = A
    Plus/minus = A
    YWST for tax (to knock of the previous effect - to be used for posting to G/L)
    Condition class = A
    Calculation type = A
    Plus/minus = X
    YOO7 for discount (to knock of the previous effect - to be used for posting to G/L)
    Condition class = A
    Calculation type = A
    Plus/minus = X
    2. The following will be the pricing procedure configuration:
    Step......No........Cond Type........... From.........to..........Man.........Req........Sta................Acc Key
    10........0..............ZR00..................--..........--..........-...........-........---.................ZDU
    20........0..............ZWST..................10............19...........----.............X............X...................
    30........0.............text.......................10...........29...........---...........----.........X
    40........0.............Z007.....................30...........39...........-----.............X............X
    50........0..............text.....................30............49...........---...........-----.........X
    60........0............ZSET.....................10...........19...........----............X............--.................ZDU
    70........0............ZDUM....................50...........59...........----............X............---...............ERL
    80........0............Y007.....................40...........49...........----.............X...........---...............ERS
    90.......0..............YWST..................20...........29...........-----............X...........---................ZWS
    ZDU - dummy account key for posting extra not required items.
    ERL - account key for price
    ERS - account key for discount
    ZWS - account key for tax.
    3. Condition records in VK11
    Condition type----
    Condition record.......
    ZR00........................................1012.5.....................INR will be positive (1012.50 +)
    ZSET.......................................100%...............................will be negative (100 -)
    ZWST.......................................10%................................will be negative (10% -)
    Z007.........................................12.5%.............................will be positive (12.50 +)
    ZDUM.......................................100%..............................will be positive (100% +)
    Y007.........................................100%.............................will be negative (100% -)
    YWST.......................................100%.............................will be negative (100% -)
    Condition records for Z007 & ZWST will be decided as per the conversion required. You will first have to manually calculate the amount for the condition type.
    4. I create a sales order for single quantity for an item & the pricing will be as under:
    ZR00 = 1012.5 (dummy account) - positive
    ZSET = 1012.5- (dummy account) - negative will knock off effect of ZR00
    ZWST = 112.5- (negative & no posting)
    Z007 = 100 (positive & no posting)
    ZDUM = 1012.5 (positive & posting)
    Y007 = 100-(negative & posting)
    YWST = 112.5 (positive & posting)
    but its not throwing any condition records for ZWST and YWST
    can any body help me

    HI,
    Plz try Routin for Vat formula.
    i am worked on MRP pricing but in our case formula is different.
    eg.: If i want to calculate VAT for B=1000 Rs. it is like
    A=1000 * ((100/100 + (12.5- VAT 5)))
    = 889
    VAT (Value) = B - A = 1000-889 = 111 which is passed to GL account.
    For that we developed one Routine with the help of ABAP and assign to Pricing Procedure.

  • HT1751 when I try to drag my Itunes into my external hard drive, I get the "no way" symbol, circ;e with a line thjrough it. How can I back up? I have lost a fortune in purchased items because I cannot back up despite following the Unhelpful help.

    I cannot drag my Itunes folder to my external hard drive, despite following the unhelpful help exactly. I get a "no way" sign Circle with a line though it. I have lost a fortune in purchased goods (audio books)  because I cant do it. Itunes have said they cant reimburse me and they dont have those books anymore, so cannot redownload them for me. Please remind me NEVER to buy apple products again.
    I am scared I am going to lose more money seeing I cant BACK ANYTHING UP.

    If you used the hard drive with another Mac then it is likely Mac formatted.  It was because you posted in the iTunes for Windows forum (kind of the equivalent to taking a VW to a Ford dealership for service) I thought you might be using a Windows formatted drive.
    Thumb drives are not universal.  There isn't a "universal" drive format.  Some work partly with both systems but are not fully compatible.
    Click once on the hard drive icon on the desktop.  Fo to File then Get Info.  It will say the drive format.
    Frankly I have never had your problem with a drive so I can't help too much except in general experience.  The prohibitory sign is pretty universal and for some reason you are not allowed to copy to that drive.
    I think if you had a Windows computer you'd be unhappy with it too and probably be posting on a forum that your machine was virus ridden and crashing and you didn't know anything about registries...  To be honest, I was doing a presentation on a friend's Windows computer and wanted to get it to display a simple image file.  There was no way we could get the .jpg image file to open with anything but Windows Explorer which is a web browser!  I mean, that's really bad, and of course he was so used to using it without knowing anything about computers that he could not help me.  I did my presentation in front of 30 people using Explorer.

  • After following the directions for attaching my IPad via the Apple digital AV adapter

    I am using a MacBook Pro.  I simply cannot find a way to attach images adjusted in Lightroom as attachments and/or without massive degradation in quality.  I follow the LR attach email process as specified by LR, the photos appear in the email seemingly embedded and the recipients of the email cannot save the attachment.

    You are welcome.  Just finished a chat session with an Apple support rep and confirmed the matte option no longer available.  Seems lots has changed since I bought my 17” 19 months back:).  They did say that there were after market screen films available from places like amazon
    Have never used anything like that though.  My wife has a 2008 MBP 15” with gloss and I can say it is a nice screen finish, you just have to be careful of lighting from behind you.  All my iMacs were glossy and I did learn to compensate for the added brilliance the screen brought to the photos.  The new soft proofing feature of LR5 seems to better estimate the level of brightness of the printed work, compared to past versions of the s/ware.
    In any case, in my opinion you really can’t go wrong with the apple product.  I bought my first iMac in mid 1999 and have never looked back.  I donated that machine to a pre-school in 2008, it was running OSX version 2 or 3 I think.  I did run Photoshop 7.0 on an IBM laptop for a time (windows XP).  I think I had one of the very first versions of Adobe Camera Raw on that machine.  I digress, sorry.
    The chat representative did confirm that the 17” is out of production and I’m guessing Apple found the market for the big laptop just wasn’t there.  They did mention that 17” MBP’s show up as “certified refurbished” units from time to time.  Suggest you might explore that option with a local Apple store in the UK, assuming  Apple has store front operations off this continent of course.
    Please feel free to contact me with further questions if you wish.
    Take care, Gordy

  • How do I create gradients (only a few steps) that follow the contour of the artwork?

    I am creating a 'How to' diagram using illustrations from a previous artist. As such I need to recreate his way of creating image gradients. He seems to do it by using only a small amount of gradient steps creating quite block like gradients. Like this: How would I go about getting my smooth gradients like this? At the moment I am creating a smooth gradient filled object, expanding it then specifying the steps in the dialogue box that then appears. But this does not really recreate the same gradient (please see as follows):So my question is does anybody know how this artist has done this? As the gradients also seem to follow the contours of the object.
    Thanks in advance,
    Olly

    Olly,
    If you do wish a more precise recreation, I am afraid you need to approach it some other way.
    As I see the original artwork, it has small roundings at the left end, and it has a dark outer stroke and a blend inside from bottom to top, and on top of that it has three slightly shorter parts, the two lower ones abutted. Everything narrower at the left end, except for the stroke which is uniform.
    You may recreate all that in this maybe rather silly way:
    1) Create a rectangle with the original width and right side height and with the same Stroke Weight and colour as the original and with a solid fill the same colour as the original at the bottom, then create a corresponding rounded rectangle with Corner Radius corresponding to the roundings to the right, and place it on top of the rectangle;
    2) Select both and Pathfinder>Divide, then delete the corner paths to the right, then select the rest and Pathfinder>Unite (or whatever it is called in your version to get one path with rounded corners to the right, then scale the H value to the original left side height;
    3) Copy 2) to the front, remove the fill, and lock the copy (which holds the stroke), to work on with the fill/nostroke path;
    4) Create two copies of 2) and hide the topmost one;
    5) With one of the top Reference Points ticked in the Transform palette, select the visible copy path 4) and reduce the H value to a small suitable value (1pt or something, depending on the size);
    6) Select 3) and 5) and Object>Blend>Make (with Smooth ticked in Object>Blend>Options), this should give you the background fill;
    7) Show the copy hidden in 4) and reduce its height to 1/6 (divide the H value by 6), change the fill to the right (darker) solid colour/shade, move it to a position 1/6 up, and reduce its W value by a small amount so the bottom fill shows at the ends;
    8) Move a copy of 7) 1/6 up;
    9) Move a copy of 8) 1/3 up;
    10) Adjust the colours/shades of 8) and 9), unlock the stroked path from 3), and Group everything, now you should have the whole artwork represented, only rectangular;
    Depending on version, you may then:
    11a) For the newest version(s) create an Art Brush to be applied to simple paths with decreasing width towards the right, or
    11b) For any version, Direct Select the Anchor Points to the far right, and Object>Transform>Scale vertically to get the original height to the right.
    Here is an image in greys, indicating the look after 10) and 11) (the stroke should have been wider, eating away more of the height of the bottom fill blend):

  • How to change the "short name (account name?)" and home directory name?

    Hi,
    I recently purchased a new iMac and migrated account info from my MacBook Pro.  I happened to use random account name during migration without knowing it will not be easy to change the short name (account name?) and home directory name.  As a result, I am now having extremely confusing short name and home directory name on my new iMac.
    I did online search to find out how to change the two names, but I could only found somethig like "enabiling root user and....."  I have no idea what it was talking about and I don't want to take risk altering such advance set up manually.
    Please advice how I can change the short name and home directory name safely without much PC knowledge.
    Thank you very much in advance.

    There are a few ways of doing this. The easiest method is logging into the first account and copying everything to an external drive (or flash drive or whatever), which changes the permissions so that others can see the files.
    Then, login with the new account and copy the files over. Once they are copied, the correct permissions will be applied again (so other people on your computer can't access them).
    If you can't do this method for one reason or other, you can do some terminal commands to change the ownership of the files. Login to the new account. If it is an admin account, open terminal and type the following command:
    sudo chown -R -v yourusername:admin /Users/originalaccountnamehere
    That should change the ownership of the files from your old account to the new one. At that point, you can simply drag the files into place.

  • How to change the short name????

    Just a general reply this, but I had to click on 'Reply' to someone's post...
    It strikes me as very strange that something with such devastating consequences is even provided as an option in Finder. How many posts have there been saying "Help, all my settings/docs/music have gone!" or similar, and the poster having to be walked through the remedial steps? What useful purpose can there be to being able to rename the 'short name', and therefore the 'Home' folder, with a control-click?
    Dr Smoke has a 'Recovering from Re-naming you Home folder', and presumably there is a Knowledge base # for it too. Surely the simplest thing to do would be, in a future SW Update, to remove that Finder option entirely. If it's necessary for some diagnostic purposes to rename, then let there be a more arcane way of doing it, surely.
    Just my humble opinion, of course...
    & yes Jon, my reply to Ozzman was curt, unhelpful and non instructive. I apologise for that. It was late & I'd been up since 5am. I should have left well alone if I wasn't prepared to more helpful.

  • How to handle the short dump

    HI EXPERTS,
    I've got a short dump to handle.
    When my functional consultant goes to:
    Transaction SPRO->clicks on SAP REFERENCE IMG->clicks on FIND button-> enters "FUNDS MANAGEMENT" as search term.->then when he clicks on any of the result of the displayed hit list he gets the following dump.
    ERROR:
        An exception occurred that is explained in detail below.
        The exception, which is assigned to class 'CX_SY_DYNAMIC_OSQL_SYNTAX', was not
         caught in
        procedure "STREE_READ_NODE_GENER" "(FUNCTION)", nor was it propagated by a
         RAISING clause.
        Since the caller of the procedure could not have anticipated that the
        exception would occur, the current program is terminated.
        The reason for the exception is:
        The running ABAP program attempted to execute an Open SQL statement in
        which a FROM clause was specified dynamically in the field "TABLE_NAME". In
         this
        FROM clause, either a table name after a join operator is missing, or an

    HOW SHOULD I GO ABOUT IT.
    PLEASE HELP.
    ITS URGENT.

    If it is an standard SAP App...You should create an OSS Note.
    If the short dump is on a custom App, you should use TRY - CATCH keywords.
