Is it necessary to download and set up jco.zip

hi
i want to know that is it necessary to install jco to connect to sap from my java class if so where i can get this .... i don't have licence in services.sap.com ....pls  help me out from this...
tx and regards

Hi Rupesh,
The JCo lib of course is already installed on the server. But you'll have to reference it at least at design (compile) time; I'm unsure if they are extracted for a direct use in NWDS. If not, use some tool which searches within JARs (like WinRAR) and search for the JCo implementation classes. You then could reference them from NWDS.
As I'm unsure where they are built in, I'm also unsure if it's needed to explicitely reference them at runtime (via SharingReference in portalapp.xml). As far as I remember just from my mind, it is needed. But if you don't get it working from this description, please come back, in 8 hours I could check this out in detail...
Hope it helps
Detlev

  • I downloaded and set up Photoshop.  When I click on the 'exe', nothing happens.

    I'm using Windows 7.  I have the extract files on my desktop.  When I set up the application, it saved to my program files.  I clicked on the EXE and nothing happened.  I moved the folder that contained the EXE and all other files, moved to my desktop and tried from there.  Still nothing happens.

    AlyxNYC first you will want to move the application back to either Program Files or Program Files (x86) depending on your operating system.  Photoshop will have difficulty launching if it is not in it's installed location.
    Beyond that do you receive a specific error message?  What version of Windows are you using?

  • Download and Set up PhotoShop Premier 12

    It is not working at all. I am losing hours that I will never get back.

    You haven't indicated where in the process things fail so I can offer am option for where it all begins.  You can skip the download manager and download a trial version directly using the links on the page linked below.  If you have a serial number you can then convert the trial to full use.
    Be sure to follow the steps outlined in the Note: Very Important Instructions section on the download pages at this site and have cookies enabled in your browser or else the download will not work properly.

    hello, there's a general regression in firefox 27 that won't allow files to download directly into a root drive. please try to create a subfolder (like ''E:\Downloads'') and set this as default location for downloads...

  • Just purchased a ipad2, could not us it on my MacBook 10.4.1 - Purchased and installed OSX Snow Leopard 10.6.3 - downloaded and installed latest itunes, set up a itunes accounts and tested by purchasing an album and app, ipad does not show in devises?

    I just purchased a ipad2, it would not work on my MacBook 10.4.1 I purchased and installed OSX snow leopard 10.6.3 downloaded and installed the latest itunes, set up an itunes account, purchased some music and apps.  When i plug in my ipod it shows up and works, but when i plug in my new ipad the ipad screen comes up with a display of a cable and itunes but does not show in devises, i have tried all the resets and different USB ports with no success.  Any ideas short of selling it on ebay or buying a new computer?

    If you've already tried the usual rebooting of the computer and ports and stuff, there is only a few things left I can think of. It's possible that when you updated iTunes it didn't fully replace all the files, so I suggest just manually removing iTunes and then reinstalling it.
    Try removing iTunes manually first http://support.apple.com/kb/HT1224 then download a fresh copy, make sure it is 10.3.1
    It is essential that you go through Finder to remove those files it mentions. Otherwise they won't be reinstalled when you run the installer again.

    I downloaded a ringtone yesterday and set it as my default ringtone.  Today it is gone and my ringtone is the standard default that came with the phone.  I cannot find the ringtone in my settings and I don't want to have to pay for a ringtone for the third time.  The ringtone does show up in my purchased file in itunes.  How do I download it again?

  • GPO is set for "Auto download and notify for install" but it does not work correctly on two of my servers.

    Hello,
    I have a problem with two of my servers. I have ~200 servers which are updating fine through WSUS. The settings are as you can see "3 - Auto download and notify for install" in the GPO.
    This is the correct setting. I want to achieve that I can install the updates whenever I want on these servers. On client computers there is a strict schedule with auto installs.
    My GPO works fine for 98% of my servers. On two servers (a big file server and a TMG server) the settings are made as you can see in the screenshots, but the updates still get installed automatically.
    I have no idea what I'm doing wrong here... It is a big problem for me that updates get installed automatically on these servers.
    Although the Policy and the Registry both say 3 the server behaves like option 4 is active.
    I would be very thankful for any input on how to find out what's the issue here.

    and was not able to find any sign of an admin installing it in the WindowsUpdate.log.
    Then the Windows Update Agent DID NOT install this update, and it's not really a WSUS issue.
    My typical response to such a claim would be to ask you to show me in the WindowsUpdate.log where the update was installed... but it seems that request has already been answered.
    The more relevant question it seems, is HOW DID these updates allegedly get installed?

  • I downloaded Ringtone from iTunes into my iPhone 6 and set it as the default Ringtone. Worked well until I had to recharge my phone. Now disappearred from my iPhone but shows in Tones when phone sync'd. How do I get to show back as default Ringtone

    I downloaded a Ringtone from iTunes into my iPhone 6 and set it as the default Ringtone.Worked well until I had to recharge my phone.The Ringtone has now disappeared from my iPhone and I'm left with just the Ringtones that come standard with iPhone 6. I sync'd my phone and it shows in the Tones folder. How do I get the Ringtone back as a default Ringtone in my iPhone 6. Quite frustrating!!

    In iTunes, try signing out of your Apple ID & then back in: click on iTunes Store on the left sidebar of iTunes, click on your Apple ID on the top right, sign out, sign back in.  Then try to sync your purchased music to your phone again.

  • I have downloaded ICloud and set up my account on my Ipad and downloaded the ICloud control Panel on my PC

    I have downloaded ICloud and set up my account on my IPad as well as downloaded the ICloud Control Panel on my PC  (Windows7/Microsoft Office7).  My problem arises when I go to sign in on ICloud on the PC.  It will not let me set up.  I receive the message, "You can't sign in because of a server error.".  Please help.  I spent all day yesterday trying to make this work for the syncing of photos, at least.  Thank you for any help.

    Hello Krish_12,
    This may be a result of security software interfering with the iCloud Control Panel's ability to communicate with our servers. The following article provides information that can help correct this.

  • Is there a setting that allows for simultaneous downloading and watching of a rental movie on ATV?

    Is there a setting that allows for simultaneous downloading and watching of a rental movie on ATV?

    Apple TV has no storage, it is caching the movie and needs to load a portion before playback starts. The time it takes is dependent on your network.
    What is your current connection via speedtest.net?
    Make sure DNS is set to auto (settings - general - network)
    If on wifi try ethernet

  • I downloaded and installed TB and it pre-configured my wife's mailbox instead of setting up a new one for me. Whats up with that?

    I downloaded and installed TB and it pre-configured my wife's mailbox instead of setting up a new one for me.
    The first time I ran it, there was her mailbox and all the msg's. I didn't input anything for a server, login or password. IOt just came up configured for her mailbox! Did it do that from the IP address or what?

    I would guess that Thunderbird has been installed previously and it has simply rediscovered an old profile folder.
