I am having a problem when downloading a file. What can I do?
Today (April 8, 2011) when I tried to download a file (.zip) firefox froze. When firefox got to the download window (i.e where you choose to save the file onto you computer) it froze. It wouldn't save the file, nor would it let me close the download window and cancel the download. This has happen twice this year. I had to force quit the program. I am on the latest version of Mac OS X and firefox 3.6.16.

Seem all correct infact the program download a file XML but the file have the encoding="UTF-16" also if i have specified "iso-8859-1" and if i tried to opend the xml file the file appears not correct because is generated with as first character "#", why?
Below the xml generated..
What i have to do to generate a correct XML without errors?
#<?xml version="1.0" encoding="utf-16"?>

What is the problem when opening jpg files using Desktop API
Hi, i would like to open jpg, or gif files using Desktop API, and the application crashes.The Desktop API is supported by my OS, because txt files, or file directories can be opened, mails can be sent, browsing is also supported.
Only jpg and gif, and i think other picture formats cannot be opened.
Obviously ACDSee and other picture viewing programs are installed in my computer.
The corresponding application code can be found at the bottom of the page of http://www.awprofessional.com/articles/article.asp?p=661371&seqNum=2&rl=1
my code:
if(Desktop.isDesktopSupported()){
Desktop desktop=Desktop.getDesktop();
try
desktop.open (fileToOpen);
catch (IOException ioe)
JOptionPane.showMessageDialog (frame,
"I/O problem");
catch (IllegalArgumentException iae)
JOptionPane.showMessageDialog (frame,
"File doesn�t exist");
fileToOpen is obviously a File.
Thx for the help in advance.

javahelpsMy file association for jpg files is correct, if i click on a
jpg, ACDSee starts immediately.Although I am a long time Windoze non-user, I vaguely remember that there's a difference between correct file-type association being set and some application starting at a mouse click on a file icon. I also vaguely remember Windoze file-type association mechanism uses a few action-types. Java Desktop should expect a specific action-type for the association. -
Problem when loading xml file using sql loader
I am trying to load data into table test_xml (xmldata XMLType)
i have an xml file and i want whole file to be loaded into a single column
when i use the following control file and executed from command prompt as follows

the file is being loaded into table perfectly.
unfortunatley i cant hardcode file name as file name will be changed dynamically.
so i removed the block
BEGIN DATA

from control file and tried to execute by giving file path from command line as follows
sqlldr $1@$TWO_TASK control=$XXTOP/bin/LOAD_XML.ctl data=/u01/APPL/apps/apps_st/appl/xxtop/12.0.0/bin/file.xml direct=true;
but strangely it's trying to load each line of xml file into table instead of whole file

Edited by: 907010 on Jan 10, 2012 2:24 AMbut strangely it's trying to load each line of xml file into table instead of whole fileNothing strange, the data parameter specifies the file containing the data to load.
If you use the XML filename here, the control file will try to interpret each line of the XML as being separate file paths.
The traditional approach to this is to have the filename stored in another file, say filelist.txt and use, for example :
echo "/u01/APPL/apps/apps_st/appl/xxtop/12.0.0/bin/file.xml" > filelist.txt
sqlldr $1@$TWO_TASK control=$XXTOP/bin/LOAD_XML.ctl data=filelist.txt direct=true; -
I have formatting problems when deploying Help files using RoboHelp 8
When i deploy the Help files. The formatting of the Numbering/bullets are affected and it is parts of the help files that i have not changed. Is there something else that i need to do to fix it?
More information needed to help you.
What sort of help are you generating?
Are you saying it is OK in Design Editor and not in a brower, if you are generating WebHelp? If yes, what browser and is it the same in all browsers?
There are some pages on Lists on my site.

How to download a file using servlet
I have a problem about downloading a file using a servlet.
Anybody can help me?
ThanksI am assuming that you want to write a servlet that, when invoked by a user (for instance, through a URL link), will download a file using the "save as" dialog (on Windows, for example) in the user's browser.
In such a case, all you need to do is get the OutputStream from the response object, set the proper MIME type header, and write the file. Here is an (untested, not even compiled) skeleton.
public class MyServlet extends HttpServlet {
protected void doGet (HttpServletRequest req, HttpServletResponse resp)
throws ServletException, IOException {
ServletOutputStream out = resp.getOutputStream ();
resp.setContentType ("application/x-foobar");
while (/* whatever */) {
In this loop, you generate your "file's" data.
You can compute it on the fly, pull it from a database,
read it from a "real" file, or any other means you can dream up.
The sample line below just writes some of the data (for example,
a byte array) to the user's browser via the output stream out.
out.write (data);
out.flush ();
Go to http://java.sun.com/j2ee/sdk_1.3/techdocs/api/index.html
for the JavaDoc on the classes used.
Cheers!

I can not download any files using Safari ? when I choose to download application file the URL include the file name and stop responding. Any help??
Please read this whole message before doing anything.
This procedure is a test, not a solution. Don’t be disappointed when you find that nothing has changed after you complete it.
Step 1
The purpose of this step is to determine whether the problem is localized to your user account.
Enable guest logins* and log in as Guest. For instructions, launch the System Preferences application, select Help from the menu bar, and enter “Set up a guest account” (without the quotes) in the search box.
While logged in as Guest, you won’t have access to any of your personal files or settings. Applications will behave as if you were running them for the first time. Don’t be alarmed by this; it’s normal. If you need any passwords or other personal data in order to complete the test, memorize, print, or write them down before you begin.
Test while logged in as Guest. Same problem(s)?
After testing, log out of the guest account and, in your own account, disable it if you wish. Any files you created in the guest account will be deleted automatically when you log out of it.
*Note: If you’ve activated “Find My Mac” or FileVault in Mac OS X 10.7 or later, then you can’t enable the Guest account. The Guest login created by “Find My Mac” is not the same. Create a new account in which to test, and delete it, including its home folder, after testing.
Step 2
The purpose of this step is to determine whether the problem is caused by third-party system modifications that load automatically at startup or login.
Disconnect all wired peripherals except those needed for the test, and remove all aftermarket expansion cards. Boot in safe mode* and log in to the account with the problem. The instructions provided by Apple are as follows:
Be sure your Mac is shut down.
Press the power button.
Immediately after you hear the startup tone, hold the Shift key. The Shift key should be held as soon as possible after the startup tone, but not before the tone.
Release the Shift key when you see the gray Apple icon and the progress indicator (looks like a spinning gear).
Safe mode is much slower to boot and run than normal, and some things won’t work at all, including wireless networking on certain Macs.
The login screen appears even if you usually log in automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.
*Note: If FileVault is enabled under Mac OS X 10.7 or later, you can’t boot in safe mode.
Test while in safe mode. Same problem(s)?
After testing, reboot as usual (i.e., not in safe mode) and verify that you still have the problem. Post the results of steps 1 and 2. -
I've been bitten by the "Missing MSVCR.dll file" problem when downloading the latest iTunes update, 11.4.62 (on a PC w/ Win-7 & Outlook-2007#. 'Have followed Apple's instructions of un-installing all Apple software, and re-installing it (Ugh). First result Outlook couldn't find my 1,385 item contact file in iCloud, although the outlook distribution lists were there. Second result, upon installing iCloud again, I have two iCloud contact files shown in outlook - "iCloud" & iCloud, within iCloud". 1,332 & 1,385 contacts respectively.
Plus an iCloud installation error message saying iCloud moved 6,835 files to a "deleted items folder" somewhere. This is NOT fun at 72-yrs old...!!
So, how do I make sure I haven't lost anythying from Outlook? Russ-AZInteresting response, Kappy - Back to original post: "First result: Outlook couldn't find my 1,385 item contact file in iCloud, although the outlook distribution lists were there (therefore, initially I had lost my contact file from Outlook). Second result, upon installing iCloud again, I now have two iCloud contact files shown in Outlook - "iCloud" & iCloud, within iCloud". W/ 1,332 & 1,385 contacts respectively.
Plus an iCloud installation error message saying iCloud moved 6,835 files to a "deleted items folder" somewhere. This is NOT fun at 72-yrs old...!!
So, how do I make sure I haven't lost anythying from Outlook? Russ-AZ"
You can safely assume that I have tried using it! So, to make things a little clearer:
1) I now have two iCloud "contacts files", w/ a different total count. What's the difference? Why the different toatl count?
2) Since re-installing the Apple software (part of the MSVCR" recovery instructions) "couldn't possible affected Outlook", why am I getting an iCloud installation error message saying iCloud moved 6,835 files to a "deleted items folder" somewhere. What's in those files? And where are they?
Probably more important questions get down to:
3) Why is a basic Apple product upgrade "screwing-up Outlook"? This iTunes upgrade, failing to install properly forced Outlook 2007 into a 2-min start-up cycle. Which was fixed with this "Goat-Rpdeo" of re-installing MSVCR80.dll.
4) And under the latest release of iOS-7.0.4 on our iPhones, why is Apple now forcing us to use the iCloud to back-up our contacts, calendars & tasks, vs. allowing these files to be backed-up directly on our PC's via the USB cable?
Thanks again for your interest and comments. - Russ-AZ -

How to skip when downloading a files?
I'm writting an application to download files from an URL. I want to support resumming. But when the download continued, I found that the method skip() for InputStream is not working. For example :
InputStream is = new BufferedInputStream (urlConnection.getInputStream ());
try { long r = is.skip (bytesDownloaded); }
catch (Exception e) { }
But the return value in r is not equal to bytesDownloaded.
Is there someone tell me what happened and how to solve this problem?
Thanks a lot!Hai Peter,
thanks for ur ideas. i am involved in a similar
ilar work. can u specify the particular HTTP header,
which is used to tell the server to skip certain
bytes. thanks for u response.
regards
hariInstead of skipping in HTTP there is a heads which lets you specify the range of data that you want.
I do not remember the header.
But there is a way to find out
There is a download manager software called FlashGet dounload it and try to download a file using it. It shows all the communication goes bitween the server and client in a console. So you can clearly see all the headers.
Thats how I find it out -

Hi all
I am getting the following error when downloading a file
by invoking a servlet ...
The following is the offending piece of code which has the
problem ..
protected void doGet( HttpServletRequest req,
HttpServletResponse resp ) throws ServletException,IOException
resp.setContentLength ( length );
OutputStream out = resp.getOutputStream();
FileInputStream is = new FileInputStream(file);
WriteToStream(is, out);
out.flush(); // Error happens here
out.close();

Windows 8.1 account limit problem when downloading from store
windows 8.1 account limit problem when downloading from store
I have 250 windows 8.1 tablets.
I figured since you can use the same account on 81 devices id create 4 accounts.
I need to download more than 25 free apps from the store
on each tablet. Putting the same account don't work. (comes up with an error after putting on to many devices that you cant use this account now).
Whats the best way to do this ? and what if I need to download a paid app ?
Thank You.Hi,
As far as I know, One Microsoft Account may bound at most five Trusted computers. There is no way to break this limitation.

When downloading a file, "open" option does not appears, only "save" does
Before updating to 5.0, when downloading a file, I could select between "Open" and "save". Now I don't have the "Open" option. I need it because of my work and is a must have or it will take to much time to save and then opening them. In normal morning with "open" option took me like 30 minutes. Now it took me 1.5 hours and can't afford to loose that much time.
Start Firefox in <u>[[Safe Mode|Safe Mode]]</u> to check if one of the extensions (Firefox/Tools > Add-ons > Extensions) or if hardware acceleration is causing the problem (switch to the DEFAULT theme: Firefox/Tools > Add-ons > Appearance).
*Do NOT click the Reset button on the Safe mode start window or otherwise make changes.

when downloading large files such as videos of a television season do you need to turn off autolock to prevent download from halting? And if so, if the download will take a significant amount of time (not sure how much offhand) how do you prevent burn in from prolonged screen image?
Among the alternatives not mentioned... Using a TiVo DVR, rather than the X1; a Roamio Plus or Pro would solve both the concern over the quality of the DVR, as well as providing the MoCA bridge capability the poster so desperately wanted the X1 DVR to provide. (Although the TiVo's support only MoCA 1.1.) Just get a third-party MoCA adapter for the distant location. Why the hang-up on having a device provided by Comcast? This seems especially ironic given the opinions expressed regarding payments over time to Comcast. If a MoCA 2.0 bridge was the requirement, they don't exist outside providers. So couldn't the poster have simply requested a replacement XB3 from the local office and configured it down to only providing MoCA bridging -- and perhaps as a wireless access point? Comcast would bill him the monthly rate for the extra device, but such is the state of MoCA 2.0. Much of the OP sounds like frustration over devices providing capabilities the poster *thinks* they should have.
