Need to download JAR files from more than ONE HTTP-server ?

Hello,
We have a need to download JAR files for an application, from more than ONE HTTP-server, i.e. any specified HTTP-server in an extremely secure network.
Does a solution exist for this requirement ? Is it possible to design a solution our selfes for this problem ?
Best Regards
Peter

We have a need to download JAR files for an
application, from more than ONE
HTTP-server, That can be done using the extension element
from within the resources element of the main JNLP.
http://java.sun.com/j2se/1.5.0/docs/guide/javaws/developersguide/syntax.html#resources
The extension element should refer to another JNLP
(on the other site) that refers to the Jars. The jar files
in any such (foreign) JNLP need to be signed, and the
JNLP files should declare itself as a <component-desc>.
For any level of detail on using extensions/components,
download the spec. mentioned in the second paragraph
of that section linked above. Unfortunately I can find no
web browsable form of the information.
Here is an example though..
http://www.javasaver.com/testjs/jws/04/glclock.jnlp
This (sandboxed) screenaver demo comes off my
javasaver site. It refers to the JOGL API via an
extension element in the JNLP, that points directly
to the JOGL site. You might notice the security
warning that is produced mentions..
Name:      JOGL
Publisher: sun microsystems, inc
Source:    https://jogl.dev.java.net
..i.e. any specified HTTP-server in an
extremely secure network. I do not know about an extremely secure network,
but if it is OK to launch a normal JNLP for an
application with a 'main()' from the server, I guess
it should be OK to launch extensions off it - you
might need to set up some tests.

  • How to extract data into excel file from more than one internal table

    Hi Guys
                 I want to extract the data from module pool screen.
                 In screen there are two internal tables
                      1. header
                      2. items.
                 I want to extract the data as same format looking in the screen.
                 With simple Download FM we cannot do this one, because in this we   will display as continuous rows.
    <b> But my requirement is saving as table with heading, date, header details</b>
    Note that it is not the simple down load . Suggest me with example  coding

    Hi Guys,
      I think it depends on which software you will use to see the result.
      If U are using Excel, it's very easy to achieve it.
      1. Define a structure as string, the lenth depend on your need.And use the structure to define a internal table, supposed is as A..
      2. Concatenate the head data using some separator, for ex. a comma; and then add this into A.
      3. The above step's concatenate is depend on your format for request;For ex, you want to place the date at the 4th cell in excel, that means you should put three separator before the date field.
      4 Concatenate the item data into the download table.
      5. Download the table to file.
      6. Display the file, using your defined separator.
    Hope this helpful.

    Are you able to download your *.jar files directly from server
    For example say,
    http://127.0.0.1:8080/test/testme.jarIf yes,
    Then problem should be with your *.jnlp file. Check all your *.jar with respect to context location of your url from where you are downloading *.jnlp file

  • My itunes library has organically grown from more than one itunes account but all now on a separate computer.  If I upgrade to iTunes match will I have to pay for each account?

    My itunes library has organically grown from more than one itunes account (all paid for by me) but all now on a separate computer.  If I upgrade to iTunes match will I have to pay for each account or just once, for the computer?

    No.  Provided the computer that you use to upload / match your Songs is authorised to play all of the Songs all works well - once complete you can download Song files that will play on your libraries / other computers without each computer having to be authorised.

  • Form that is a map of Ohio. I created layers for each county so I can click and it highlights, but I need to be able to click more than one. How do I do that?

    Form that is a map of Ohio. I created layers for each county so I can click and it highlights, but I need to be able to click more than one. How do I do that?

    Looks nice!
    I understand what you've done now. You used the "Set Layer Visibility" command which sets the on/off state of all the layers at once. What you need is a more subtle approach, one that will only change the state of the specific layer associated with the button, not the rest of them (so that you could have multiple layers enabled at the same time). The way to do that is by using a script.
    I wrote the script for you and applied it to the top-left counties (WILLIAMS and FULTON), in the attached file. You can now copy the actions I associated with those buttons to the rest of them, and it should work as you want it to.

  • How to from more than one delivery note - conversion into one invoice

    Dear Experts,
    How to from more than one delivery note - conversion into one invoice?
    Thanks and best regards,
    Wilson Hong

    Dear Wilson Hong,
    Single invoice for multiple deliveries will takes place based on these criterion
    1.If you want single billing document for multiple deliveries these data should be same in all order for all items.
    -> Payer
    -> Inco term
    -> Payment term
    -> Actual GI Date from Delivery
    -> Shipping Condition
    -> Account Assignment Group
    -> Exchange rate (in case of export sale order)
    -> Foreign trade data.
    2.In addition to this you need to maintain proper copy control settings between delivery and invoice.
    Go to VTFL transaction input your delivery type and invoice type then go in to the item level settings here you find field Data VBRK/VBRP maintain this field with routine 3-Single invoice.
    If the above data and settings are exists you can do single invoice for multiple deliveries.
    I hope this will help you,
    Regards,
    Murali.

  • Can I tunes play music from more than one directory?

    Can anyone tell me if its possible to store music files in more than one location, say my I Mac hard drive and also an external hard drive, and set I tunes to play fiels from both locations? This is possible with Windows Media player.

    If you open iTunes and go to Preferences>Advanced>General you'll see a box "Copy files to iTunes Music when adding to library". If you have this box unchecked then anything you add to the library from say a music folder on your hard drive and another music folder on a second drive get added to the library but but remain in the original location. The library will contain the location information so the song file can be accessed when you want to play it. Of course this would mean that any songs located on the external drive could only be accessed when the drive was connected.

  • On some pages the text from more than one paragraph stack up on top of each other, like writing something then writing something else on top of it.

    On some pages the text from more than one paragraph stack up on top of each other, like writing something then writing something else over the top of it. Some pages will run text and pictures together, like a car rear-ending another or a train pile up. Other pages will cut an image or text short, i.e. it will display a portion of the top of the image or text but not the rest. This happens on Amazon for example, the section where it says "Customers who looked at this also looked at" will allow only a certain amount of the upper portion of the description immediately below the picture of the product but below that section everything is fine until I get to another section displaying more products and their descriptions and then it cuts the bottom portions off again. I've noticed this behavior mostly in the sections with product photos, the text sections seem okay. YouTube also displays this behavior. It's even doing it on this page right now. Below this box I can read "The more information you can provide the better chance your question will be answered " , but directly below that in the next sentence I can see the start of it with "Troublshootin" and the "Automatically Add" in a green field covering the "g". The next clear text is "A window will open in the top corner. Click Allow, and then click Install. If the automated way doesn't work, try these manual steps." I tried turning of pre-fetching, clearing history, cookies, and cache, scanning for malware with Avast and Windows Defender all to no avail. It began when I upgraded from dial up to DSL via AT&T Uverse. I have a Motorola NVG510 modem. The modem was replaced an hour ago along with new dedicated lines and DSL/Phone splitter from the box by an AT&T technician to make sure my incoming lines were up to par. He ran a connection test and verified everything is up to standards. IE does not display this behavior. I am running Firefox20.0.1 and all previous versions have acted the same way since I upgraded to DSL about 3 months ago.

    If you have increased the minimum font size then try the default setting "none" in case the current setting is causing problems.
    *Tools > Options > Content : Fonts & Colors > Advanced > Minimum Font Size (none)
    Make sure that you allow websites to choose their fonts.
    *Tools > Options > Content : Fonts & Colors > Advanced: [X] "Allow pages to choose their own fonts, instead of my selections above"
    It is better not to increase the minimum font size, but use an extension to set the default page zoom to prevent issues with text not being displayed properly.
    You can use an extension to set a default font size and page zoom on web pages.

    iTunes Match is not sharable across Apple IDs. The best way to get the music on her iPad is to leave hers signed into her Apple ID on the iTunes Store and sync via USB.

  • Can takes from more than one track be comped at the same time?

    Greetings,
    I know that this question has been asked recently in this forum (http://discussions.apple.com/thread.jspa?messageID=9527542&#9527542), but I don't think that the respondents completely understood the question... Or perhaps I did not understand the suggested solutions to the problem. I will ask the question in a slightly different way...
    Suppose that I record guitar with 2 microphones (a pickup mic, and a room mic). The first microphone is recorded onto track 1, the second microphone is recorded onto track 2. Multiple takes are done in this manner. When it comes time to comp the tracks, how is it done? Can the takes from more than one track be comped together at the same time? I have tried to do this by grouping both tracks together, but it does not work.
    Any suggestions?
    Thank you.

    You had the right idea grouping the tracks together. You must make sure that in the group settings, the box titled "region selection (edit)" is checked. This will allow you to make the same cuts (or in this case, swipes) on all regions in the group.
