  • I there any dependcy between Java Enterprise Edition and Java standard Edit

    Hi Friends,
    Is J2EE 1.4 uses Java SDK 1.4 or 1.5.Please reply as earlier as possible.It is urgent
    Thanks
    Bye

    Each version of the Java EE platform must be able to run on the associated version of the Java SE platform. So, J2EE 1.4 must be able to run on J2SE 1.4 , Java EE 5 must be able to run on Java SE 5, etc. Note that this doesn't mean a particular implementation of Java EE can't be run with a more recent version of the JDK. For example, the J2EE 1.4 SDK can be run with J2SE 1.4 or Java SE 5. The key is that both the implementation of the Java EE platform and the applications written to that particular release of the platform must write to the corresponding Java SE version API. In other words, neither a J2EE 1.4 implementation nor a J2EE 1.4 application should make use of an API that was added in Java SE 5.

    You have to open a connection. Get the input stream. Read the input stream. Parse the content.
    There are HTML parsers out there.

    By using URLConnection? No.
    If you use raw sockets then increase speed maybe. But "modulate" not really either way.

  • Is there any method in Java to convert from system time to variant time?

    From MSDN:
    A variant time is stored as an 8-byte real value (double), representing a date between January 1, 100 and December 31, 9999, inclusive. The value 2.0 represents January 1, 1900; 3.0 represents January 2, 1900, and so on. Adding 1 to the value increments the date by a day. The fractional part of the value represents the time of day. Therefore, 2.5 represents noon on January 1, 1900; 3.25 represents 6:00 A.M. on January 2, 1900, and so on. Negative numbers represent dates prior to December 30, 1899.
    Is there any method in Java to do this or do I need to write it?

  • Is there any difference in SAP 4.7 and ECC 5.0

    Dear,
    Is there any difference in SAP 4.7 and ECC 5.0...
    Thanx & Regards,
    Mohammad Nabi

    Hi,
    Check this out
    Hi I'm providing the ECC 6.0 functionality if you knows the
    4.7EE the difference is as follows:
    ECC 6.0 New GL Functionality
    1.Activate the New General Ledger Accounting by a single
    click on the clock icon
    2.You will reach to change view "activation of New GL A/cg"
    detail screen and tick the checkbox and save.
    3. After activation of New General Ledger Accounting, you
    exit the IMG screen when you re-enter, you find that a new
    node is added Financial Accounting (New)
    4.After activation of New General Ledger Accounting; a new
    sub node appears in the IMG structure.
    This sub node is Define Segment
    The menu path is:
    SAP Customizing IMG ---> Enterprise Structure -
    >
    Definition --> Financial Accounting --> Define Segment
    In this IMG activity, you define your segments.
    If you then define your profit centers, you can enter an
    associated segment in the master record of a profit center.
    The segment is then derived from the assigned profit center
    during posting.
    5. Activation has created a new field in Profit Center
    Master Record: the SEGMENT
    6.Leading and Non- Leading Ledgers
    In General Ledger Accounting, you can use several Ledgers
    in parallel. This allows you to produce financial
    statements according to different accounting principles. A
    ledger uses several dimensions from the totals table it is
    based upon. When defining Ledgers, one must be defined as
    the Leading Ledger. The Leading Ledger is based on the same
    accounting principles as that of the consolidated financial
    statements. It is integrated with all subsidiary ledgers
    and is updated in all company codes. This means that it is
    automatically assigned to all company codes. In each
    company code, the Leading Ledger receives exactly the same
    settings that apply to that company code : the currencies,
    the fiscal year variant and posting period variant .
    You must designate one of your ledgers as the Leading
    Ledger. It is not possible to designate more than one
    ledger as the leading ledger.
    The menu path is:
    SAP Customizing IMG -
    > Financial Accounting (New) -
    >
    Financial Accounting Basic Settings (New) -
    > Ledgers ---
    -> Ledger -
    > Define Ledgers for General Ledger
    Accounting
    Clicking on the checkbox identifies one of your ledgers as
    the Leading Ledger.
    7. Activation of Non Leading Ledgers
    Non Leading Ledgers are parallel ledgers to the Leading
    Ledger . They can be based on local accounting principle,
    for example. You have to activate a non- Leading Ledger for
    individual company codes. Non- Leading Ledgers can have
    different fiscal year variants and posting period variants
    per company code to the Leading Ledger of this company
    code.
    The menu path is :
    SAP Customizing IMG -
    > Financial Accounting ( New ) -
    > Financial Accounting Basic Settings (New) -
    > Ledgers -
    ---> Ledger -
    > Define and Activate Non --Leading
    Ledgers
    8.Assign scenarios to ledgers
    A Scenario combines Customizing settings from different
    business views. Each business view specifies which posting
    data is transferred from different application components
    in General Ledger Accounting, such as cost Center update or
    Profit Center update .You assign the desired scenarios to
    your ledgers. For each ledger, you define which fields are
    filled with posting data from other application components.
    SAP delivers a number of scenarios in the standard system.
    It is not possible to create additional scenarios.
    The menu path is:
    SAP Customizing IMG -
    > Financial Accounting (New) -
    > Financial Accounting Basic Settings (New) -
    > Ledgers -
    --->Fields -
    > Display Scenarios for General Ledger
    Accounting.
    9. Cost of sales accounting
    Cost of sales accounting is a way to create a profit and
    loss statement (P&L) for a company by comparing the
    revenues to the costs or expenses incurred to obtain these
    revenues.
    The expenses are mainly divided by functional area such as:
    Manufacturing
    Administration
    Sales
    Research and Development
    We can activate Cost of Sales Accounting by the following
    menu path :
    SAP Customizing IMG -
    > Financial Accounting ( New ) -
    -> Financial Accounting Basic Settings (New) -
    >
    Ledgers ->Ledger---> Activate Cost of Sales Accounting
    Offsetting Account Report ECC 5.0
    Offsetting account report for vendors in ECC 5.0 is
    possible after implementing the OSS Note 1034354

    Where is the bookmarks stored?
    I Install the Firefox once again since I upgrade my computer.
    And I try to move the bookmarks from the old computer to the new one.
    But I can't find anyone of them.
    Is there any folder just like "favourite" to store the html file?
    I really want to find out the bookmarks because actually i can't remember all the website that are important to me~ URGENT!!!~THANKS~

    You can move file named places.sqlite from your old profile to the new one. It contains bookmarks and browsing history.
    Here's a knowledge base article about it: [[Recovering important data from an old profile]]
    If you don't care about saving your current bookmarks, you can skip creating new profile (Firefox does it by itself at first run anyway).
    I'd might suggest you to install addon https://addons.mozilla.org/en-US/firefox/addon/2410/|Xmarks Bookmark and Password Sync]. It is a free web service which synchronizes bookmarks and (optionally) passwords with central server, and then to other computers, if you installed it on more. You may treat is as a backup too.

Already lost two songs!!!  I just want a back up - using a work PC and don't want others accessing my songs.  Hope someone can help.  Thanks!

    I see. To get a better idea of what is being stored where please download and run the script iTunesInfo which should output something like this:
    I'm interested in the block of 4 results starting ITL location. If your profile name shows up somewhere replace it with <Name>.  It is also worth checking under Edit > Preferences > Advanced to see where iTunes thinks your media is supposed to go. My script estimates the setting based on the location of the first media file it can actually find.

    I have installed mountain lion on my early 2009 macbook (not unibody) and it is terrible, it's like owning a windows pc again (almost) What can I do? I paid for mountain lion, is there any way of giving it back and getting a refund? obvisoulsy after unintalling it. I couldn't see any reason why it would be bad for my particular macbook, and it downloaded without a problem.

    In what way is it terrible? Mountain Lion is pretty stable. If you are having problems, most likely they are unique to your particular system and can be fixed. If you don't like some of the new features, that does not constitute reason for a refund.
    If that does not suit you, you will have to discuss a refund with Apple, as they are the only ones who can say. Note that the App Store terms do say that all sales are final, so you are not guaranteed a refund, especially since whatever problems you had are not due to defective software.
