Dialup jar download error

Hi,
We are seeing an odd occurence. Our dialup users using Java Web Start are unable to download certain jar files if they are a certain size. For example when we deploy our code we need to verify that it will work over a dialup connection. If it does not work we add an additional file to the jar until we get to a size that works???? We can consistently recreate this. We have expirienced it at two different jar sizes so far (255-265 Kb + 320-330 Kb). We have a work around by adding files until it works but this is a hit or miss type of fix. We use signed jar files. The error is a download error. Any help would be appreciated.
Thanks

The ISP that we recreated the error on was ATT World Net. The error message that we are seeing is:
Category Download Error: Corrupted JAR fiel at <our URL>
ZipException: Error in opening zip file.
We are using version 1.4.2_03 of the JRE. We download 4 separate jar files during the launch of the jnlp. If any of these jars are at the odd sizes previously mentioned it will appear to hang, then after a while we will see the error messages above.
Thanks

Download Error Exception in 1.6. Works in all older versions.

I have attached the HTTP headers at the bottom.
Any ideas?
BTW, it would be great if SUN could make things backward compatible. This JNLP file is integrated inside a product and requires that all customers upgrade the product.

Jar download not working over dial up

Hey,
Our webstart application works just fine while connected to the lan at work. The various jars required by the application are downloaded without any problems.
However, when I try to access the same application over dial up (I have tried netzero and aol), the jar download fails in a rather weird fashion.
On clicking on the link for the application, the main jar e.g. main-application.jar downloads just fine, but the next jar in line fails with the following message
Unable to load resource: https://server.com:443/application/lib/axis.jar
Exception

Now, when i click on the application launch again, it proceeds to download the next jar e.g axis.jar in this case without a problem, but it will fail on the next jar
snippet from my jnlp file
<jar href="application.jar"/>
<jar href="lib/axis.jar"/>
<jar href="lib/castor-0.9.5.2-xml.jar"/>
<jar href="lib/commons-beanutils-1.5.jar"/>
<jar href="lib/commons-collections-2.1.jar"/>
Note : All of this works fine when im not using dial up to connect.
Does anyone have any ideas ?
Any help is greatly appreciated

pboeykens,
It may definitely be something with my network and/or firewall configuration. I'm just not sure where to look yet.
I have tried modifying apache settings to no avail.
I've tried turning KeepAlives off, changing the keep alive timeout and the max number of keep alives allowed on apache, but none of these setting changes had any effect on the jar download.
If you have any suggestions for what I might look at as far as my firewall settings, then I can take that to my security department.
My next step is to try and enable the debug logging with webstart to maybe get a better idea of why it thinks that no jar is available.
Thanks

How to solve this issue .
But the same file is working in Tomcat Server
please let me know
Thank you
Prakash

Bad MIME type returned from server..A server should return a content type of..
application/x-java-jnlp-file for JNLP
files.
Tomcat probably does that by default, but
other servers might need to be told about it.
See your server help, for how to set a
content-type.

Download error for explicit tracks?

I get the message "Download error. Tap to retry." in the iTunes store on my iPhone when I try to download explicit tracks that have been Matched not uploaded. They will get about 80% downloaded and then just stop every time I retry. I've tried deleting them and redownloaded the tracks but nothing seems to work. One of the songs will play most of the way through and stop and the other two will not play at all.
I have an iPhone 4S running iOS 5.1 using iTunes Match.
Thank you

If you are using dialup or satellite for internet, latency in the internet connection can cause downloads to fail part way. For those, you'll want smaller segmented archives to be sent to you. Same if the sender has such a connection. Cable, DSL, and FiOS this is much less likely. Data corruption on your hard drive is more likely to fail extracting of a zip file on Cable, DSL, and FiOS connections. What kind of connection do you have? Is your data backed up so we can analyze why this is happening?

My DVD drive is dead so I can't save them to a disk. I do have an external CD drive.
From the sounds of this statement, it sounds like you are assuming having a DVD or CD drive that works would make a difference in being able to save to disk.
CDs and DVDs don't allow direct saves like a hard disk. They require a separate burn command to burn to disc. Except for DVD-RAM, all optical medias for CD and DVD drives allow only limited rewrite capability, and require special steps to write to disc. If a disc is -R or +R, it can be written sessions until it fills up but again requires the use of disc burning software at the operating system level, or third party. If a disc is -RW or +RW you can erase the disc and write whole new blocks of files as a rewrite of the disc. But you can't selectively write over existing blocks with either.

Download error v551

Hello this is my first jar file... wooohooo
Everything works on my pc... on all the emulators-and the motorola launchpad.
However after creating the .wml file and uploading to the server...
When I go to download the file I get a progress bar that locks up at 0 download and then a download error... the file is only 2151 bytes.
I have checked the .jar file for the size to be the same...
any ideas?
the .wml is at www.eftekhari.com/time/time.wml
thanks

Is this something with the server?
And does anyone know of a free server I can upload my wml jar jad file to?
I get the same problem with files I try to download from www.tagtag.com
If someone could also post a url that has a file I can download on my v551 phone that they know works would help a lot.
Thanks for any help you can provide.

Urgent: download error from webstart

Hi, Gurus:
When webstart download some big jar files from server to client side, most of time, we got download error and got to re-connect server to download the rest of that jar file.
So is it possible to saperate the big jar files into small pieces when download with java web start? Or any good idea to speed up the download with java web start?
Your prompt reply will be great appreciated!

OK, all my fault. Turns out it was a firewall my office uses that stops streaming!
All sorted.

N96 wont accept Jar downloads

For the past few days my n96 will not allow JAR downloads to reach more than 3/4's of the total download .It then says, "unable to download." I know it's not the apps or games i'm trying to download because a few of them were things I had downloaded successfully a few days earlier but deleted for one reason or another. Since I knew they had no problem being downloading I used them to see if the problem was the new downloads and it isn't. Sis files seem to have no problem but jar files won't download anymore. Any suggestions? thanks JL2

i have the same problem, i was trying to download from Ovi and i got an error Jar and jar file aren't the same size... like what does that mean???? i've requested help, so if i get an answer i'll pass it on to you.

Download error in (osx) adobe desktop app (corrupted download link).

Here is a discription of the problem. Please consider that some of the wording might not be correct, as I do have to translate the error message from German into English.
Using OSX 10.9.2, when clicking inside the adobe desktop app (top of the screen bar) on the tap "apps", the following screen (screenshot) appears, which states, translated from top to bottom:
download error
download error. Please contact support.
(link) contact support
(link/button) download creative cloud -> This button unfortunatly leads to the following error page "http://www.adobe.com/special/errorpages/404.html"
All apps, like Bridge, Photoshop, Lightroom, etc. are installed and work just fine. So no problem here. I seem however unable to redownload the desktop app (in order to reinstall). As stated above the provided link inside the desktop app itself is coruppted and within the (online) web-based download centre (user logged in) I am only adviced to use the desktop app. This is a dead end and I do not know what to make of this error, let alone solving it. Please help!

I am sorry Romsinha but this doesn't really help.
I already restarted the desktop app and while I am obviously online and connected the problem (error message) remains the same. Information within the "home" tap is recieved/loaded (little blue spinning wheel) stating that various apps recently have been updated. Yet the same loading wheel within the "apps" tap results in an error. My best guess is that some internal link within the app is corrupted, leading to a source on a server that can not be reached.
UPDATE
I clean uninstalled adobe creative cloud as discribed in the article you provided (using the cleaner tool) and even uninstalled the browser plugin. After downloading and reinstalling creative cloud the problem however remains the same. "Apps" tap still shows the same problem. "Home" tap now displays the following:

"Download Error" - Can't download/install any programs.

I downloaded CC on my Win 8.1 machine (after a windows crash and upgrade to 8.1). Previously it was working fine (on Win 8). Now the CC desktop app connects to my account but the Apps tab has a red exclamation error and when you click the tab it says "Download Error." and to "Please contact customer support." (See below:)
Apparently this seems to be a prevalent issue as I see multiple threads and support requests with this same error.
I got on Chat and followed all the troubleshooting advice, uninstalled, reinstalled, used the Removal tool, deleted folders from the AppData locations, everything. Finally was getting ready to do something else and the Adobe server disconnected my chat session.
I know it is not MY internet connection because everything else is up and running fine, including streaming radio progams and other chat programs.
I tried visiting something on Adobe's siteand received the following error:
So what is going on Adobe? I need to get my programs back so I can get back to work.
Edited to add - After another hour of being on chat support I got disconnected again. Same error: "Sorry, we're having technical difficulties."

So after four hours and dozens of troubleshooting issues, I figured out what was wrong. I am on a fixed-wireless system at home. I have used this same system and network setup in the past for CC. My average DL speeds are 2.0 Mbps. Not super fast but it has worked in the past. On the 3rd or 4th chat session I was told that you can't use wireless with CC and I need to be on a fixed wired connection. Finding that as rediculous as possible, I decided to test my network. I logged off and used my AT&T CELL PHONE as a hotspot (which gets me about 4.0 Mbps download speeds, albeit with a higher ping) and VIOLA the Apps tab is there and I can download programs.

Download Error on Mavericks (mac)

When I go to the Creative Cloud application on the desktop, I go to the Apps tab and I get "Download Error" and when I try to reload the application, the error persists.
I'm on a macbook running Mavericks, I've deleted the AAMUpdater (though it creates a new one every time I reload the applications) folder in ~/Library/Application Support/Adobe... As per Re: Creative Cloud "Download Error" message , I looked in the OOBE folder and there was no opm.db, just a singe folder alias called "PDApp," which contained a pim.db, along with a bunch of other folders and files.
When I enabled the root user and logged into that account after restarting, I tried the Apps tab again and it was working just fine, in the root user. But when I logged out and back into my regular account, I was still getting the download error. I've tried uninstalling and reinstalling Creative Cloud and that didn't work. I have Photoshop and Fireworks installed, so it WAS working at some point in time... I'm out of ideas... Help please?

Adobe Application Manager Download Error (and other problems)

Last week I purchased a Creative Cloud membership (Student and Teacher Edition, if that matters at all). When I tried to download applications, the Adobe Application Manager seemed to be unable to connect and instead displayed "Download Error. Press Retry to try again or contact customer support." I read some of the responses to this problem on the forums, and after trying several things, I got it to work (I'm honestly not sure what I did that caused it to work). However, it is now failing to work again and I can't seem to fix it this time. As an additional problem, When I tried to open Adobe Premiere Pro (which I managed to download when I got the App Manager working for a while), I got the opening screen that asked me to open a project or start a new project. No matter what I clicked on, Premiere Pro closed with an error message. Just as with the App Manager (and at the same time), I managed to get Premiere Pro to work (it seemed to work after I set permissions so I thought I solved it), so I was able to use it for a day. However, now the problem has returned.
I don't know if these two problems are related, but they started working at the same time and stopped working at the same time, so I'm posting them together in case there is a connection. I am running Windows Vista on my home computer. I can sign on to the creative cloud online without problem so it recognizes me as a creative cloud subscriber. My Internet connection is working fine. I have disabled all firewalls and it still doesn't work. Very frustrating, obviously.
Thanks for your time and any help or suggestions you can give.

Kardypaine for your Internet configuration difficulties I would recommend reviewing Sign in or activation errors | CS6, CS5.5 Subscriptions, CS6 Perpetual - http://helpx.adobe.com/x-productkb/policy-pricing/activation-network-issues.html.
For the failure of Premiere Pro to open you will want to review the install log to see if you received an installation error. You can find details on how to locate and interpret the installation logs at Troubleshoot with install logs | CS5, CS5.5, CS6 - http://helpx.adobe.com/creative-suite/kb/troubleshoot-install-logs-cs5-cs5.html.
