File download from server

Hi All,
I have written a code that downloads a file from server using the following link given by Frank,
File download from server
I am able to get a open/save/cancel dialog with help of this. But issue is that applications of kind .doc/.xls/.ppt gets opened (If user clicks open) right in the internet explorer window instead of getting opened in a new office application....
However .pdf runs fine.
Can any thing be done for this???
Any help....

Hi,
what do you have for the content disposition header?
Try this:
         response.setHeader("Cache-Control", "max-age=0");
         response.setHeader("Content-Disposition", "attachment; filename=\"" + fname + "\"");
         response.setContentType("application/x-download");Brenden

The best you can do is set the correct content type.
Once the file reaches the client's browser it's up to the client and their browser settings to decide what to do with it.
You can't control the client's browser from your servlet.

PDF file downloading from server to client

Hello,
I am a newbie to Oralce UCM. Writing a component to merge some PDF files and allow user to save/open it on client side.
The file downloaded is of 0 bytes and when opened it says -
Adobe Reader could not open the the file because it is either not a suppported file type or because the file is damaged(It was sent as an email attachment and was not correctly decoded)
this.m_binder.m_contentType = "application/pdf";
this.m_binder.m_clientEncoding = "utf-8";
DataStreamWrapper dataStreamWrapper = this.createNewDownloadStream();
dataStreamWrapper.m_clientFileName = "MergedPDF";
dataStreamWrapper.m_inStream = mergedPDF.getDocumentInputStream();
dataStreamWrapper.m_inStreamActive = true;
dataStreamWrapper.m_dataType = "application/pdf";
try {
this.m_httpImplementor.sendStreamResponse(this.m_binder, dataStreamWrapper);
} catch (ServiceException e) {
e.printStackTrace();
Some clue would really help :)

Hi Jiri,
I have created and HCSP page where data is being populated dynamically. User may select some of the files from this page through checkbox. Page also has a download button which when clicked will merge all the selected documents and let the user open/save it.
Information like Native URL, docName is passed on to the content server when the component is called (download button-click).
Merging the PDFs, I have used a custom utility which takes url as a parameter and returns back the inputstream of merged PDF.
And last, I have used DataStreamWrapper to send this inputstream back to the client as an attachment which can be read by IE.
Also, I thought at first to use HTTPHeader where parameters like content-disposition, content-type can be set. But UCM already provides a better way to achieve this i.e. through DataStreamWrapper.

     public List<PdfDocumentSource> createPdfDocumentSourceList(

File Download from server to client

Please review the following code. I am attempting to download a file , whether PDF, DOC, TXT, etc.., from the server to client(in this case a DOC file). The f.exist() method returns true so the file exists but the f.length() returns 1. The file is considerably larger than 1 byte. The download occurs but the file contains 1 byte of code.
Also, please review all the code and suggest any code changes needed to complete the download. I am new to Java programming so be kind.
File f = new File(filePath + fileName);
System.out.println("file " + f);
System.out.println(f.exists());
System.out.println("file length " + f.length());
FileInputStream fis = new FileInputStream(f);
BufferedInputStream bis = new BufferedInputStream(fis);
response.setContentLength(fis.available());
System.out.println("bytes " + fis.available());
response.setContentType("application/msword");
response.setHeader("Content-disposition","attachment; filename=" + fileName );
BufferedOutputStream bos = new BufferedOutputStream(response.getOutputStream());
byte[] buff = new byte[1024];
int bytesRead;
// Simple read/write loop.
while(-1 != (bytesRead = bis.read(buff, 0, buff.length)))
bos.write(buff, 0, bytesRead);
bos.flush();
bos.close();
bis.close();
response.flushBuffer();
fis.close();
} catch(Exception e){
System.out.print("\n svtFileDownload.processRequestFileDownload Exception=" + e);

the following is a nippet from a servlet I wrote that does what you want and I've had no problems with it, even with large file 200+ megs.
            String filename = bundle.getFileLocation();
            response.setContentType("application/stream");
            response.setHeader("Content-Disposition","attachment; filename="+filename+";");
            ServletOutputStream out = response.getOutputStream();
            BufferedInputStream fif= new BufferedInputStream(new FileInputStream(FILE_LOCATION+filename));
            int data;
            while((data = fif.read())!=-1)
                out.write(data);
            fif.close();
            out.close();

File Download from Server location - JSP

Hi SDN,
I have a txt file in a folder created in server location under the path /usr/sap/EPD/JC00/j2ee/cluster/server0. On click of the link correspondin to the file name in JSP, i have to open the file with the pop up to save, open or cancel. I have to achieve this in the JSP. I am currently
<td> <a href="/usr/sap/EPD/JC00/j2ee/cluster/server0/XXX/yyy.txt"> <%=fileName%></a ></td>
I am not able to achieve the intended functionality. How to achieve it. Expecting your valuable replies
Thanks & Regards,
p188071

hi,
I am using the following snippet
String filePath ="/usr/sap/EPD/JC00/j2ee/cluster/server0/xxx/yyy.txt"; // path of your excel file
     HttpServletResponse resp = componentRequest.getServletResponse(true);
     resp.setContentType("text/html; charset=UTF-8");
       // set the exact content type
     resp.setHeader("Content-Disposition","attachment; filename=\""+ filePath + "\"");
It is creating downloading a txt file with the name usr_sap_EPD_xxx_yyy.txt without actual contents inside the file. It is just generating a file without writing the contents into that file.
What should I do?

Jar files downloaded from SkyDrive are being renamed to jar.zip files

I have cut and pasted the following series of exchanges from when I posted the problem onto SkyDrive's support forum. I hope that someone might be able to propose a better solution to the problem that I have. Thanks for your help.
MDSms asked on
Uploaded jar files convert to jar.zip files when downloaded from SkyDrive
I have uploaded an executable jar file to SkyDrive. (I will call this FILE.jar). The file is intact and indicates that it is a jar file type when the file is viewed by Properties within Skydrive. However, when I download (or others download through a share link) the file, it is being saved onto the local computer's download file with .zip appended to the file name (FILE.jar.zip). The downloaded file can be renamed to remove the .zip appendage and subsequently run successfully. However the folder options for the folder where the downloaded file resides must be changed for disable "Hide known file extensions" prior to being able to remove the .zip appendage. While I have figured out the workaround for this problem, this manual renaming procedure is entirely too cumbersome as a solution for sharing this file with others. How can I prevent or disable the FILE.jar file from being renamed to FILE.jar.zip when it is downloaded from SkyDrive?

The file was uploaded by first logging onto my SkyDrive account using Windows 7 Pro and Firefox browser, then a new folder in my account was created without sharing privileges, then the folder was opened and the FILE.jar was uploaded into the folder using the "Upload" option on skydrive account menu. Sharing privileges for FILE.jar were then created (view only), and the shortened url link was sent to the individuals that I was trying to share the file with. was then turned on. When these people use the link to download the file, it is being saved as FILE.jar.zip.
When I try to download the file through the skydrive account download option, it is being saved onto my computer as FILE.jar.zip and this occurs when I try to download the file while signed into my skydrive account as well as when I am not signed into my skydrive account (using the shared file link).
This PNG shows the information provided by clicking on the download icon (down arrow) within the Firefox browser; note that the file was downloaded as FILE.jar.zip and that the source was live.com. When I use Windows Explorer to look at the same file within the Download folder itself, examining the file's properties details also shows that it is being saved as FILE.jar.zip and is of the file type compressed zip folder.
This PNG shows the information displayed to me from my skydrive account when I view the originally uploaded file's properties; note that the information shows that the file is a jar file type.
When I utilize Internet Explorer 9 to access the file, FILE.jar is being downloaded onto my computer as a jar file type. This PNG shows the information provided by Tools/View Downloads within the IE9 browser. Note that in this instance, the information indicates that the file is being downloaded from yzudea.blu.livefilestore.com.
It appears to me that the problem (the FILE.jar file being renamed to FILE.jar.zip) arises from the fact that a jar file downloaded from skydrive using firefox, is being sent from live.com whereas a jar file downloaded from skydrive using IE9 is being sent from yzudea.blu.livefilestore.com.
I want to make sure that a person receiving a share link from me for FILE.jar is able to download it without modification to the file name regardless of which browser is being using to access the link. How can I make sure that this occurs?
Any help is appreciated. Thanks.

Hi MDSms,
I appreciate you for providing as much information as you can about the issue, as well as for uploading screenshots on what you see from the downloaded file. About your initial concern wherein the file gets renamed with .zip after the original file extension, this is solely dependent on the browser that you are using since they have a different safety/security measure that needs to be implemented.
Moreover, you may see the file servers live.com and yzudea.blu.livefilestore.com to be different with one another, but they actually are sent from the same SkyDrive server. This in turn, depends on the web browser where the file is being downloaded as well. The live.com file where it was downloaded from Firefox simply masks its original server yzudea.blu.livefilestore.com.
As for your last query about your recipients downloading the file without the hassle of renaming it from a .zip file, you can simply tell them to download it through Internet Explorer.
Should you have other queries or additional information that might help in our investigation, I highly encourage you to post them here.
Regards,
Michelle
MDSms replied on
Michelle,
Thanks for your reply. Yes, I could simply tell them to download the file through Internet Explorer, but is there another solution or workaround to the problem I have described here? Am I being punished with the curse of this problem simply because I (or the individuals with which I wish to share FILE.jar with) choose to use Firefox instead of IE? Will the use of any other browser instead of IE (Chrome, Safari, etc., etc.) still result in the same problem?
You stated that it is "solely dependent on the browser that you are using since they have a different safety/security measure that needs to be implemented"........could the problem be overcome by designating one or both of the file server addresses as Trusted Sites within the browser options setting?
I look forward to your response. Thanks in advance.

Hi MDSms,
We understand your concern. Since the issue does not occur in Internet Explorer, it has something to do with Firefox's security feature. You might want to verify this concern by contacting Firefox support.
Hope this helps. Let us know if we can further assist you with SkyDrive.

Message "not downloaded from server. You need to take this account online

After upgrading to 10.4.9, when I click on any of the old emails in my inbox I get the message "this message not downloaded from server. You need to take this account online in order to download it."
I can still read all email in any other mailbox.
I can read all email received after upgrading.
I appreciate any help.
G4 17 inch Mac OS X (10.4.9) 1 gb ram

You upgraded to 10.4.9 from what?
If you upgraded from Mac OS X 10.3 or earlier, the problem is that the conversion from Mail 1.x to Mail 2.x is broken. Take a look at the following thread to better understand the problem:
Help! "You need to take this account online in order to download it."
More specifically, if this is a POP account, the following procedure should allow you to fix the Inbox problem. A similar procedure should allow you to fix other mailboxes that might also be affected:
1. Quit Mail if it’s running.
2. Make a backup copy of the ~/Library/Mail folder, just in case something goes wrong while trying to fix the problem. You can do this in the Finder by dragging the folder to the Desktop while holding the Option (Alt) key down, for example. This is where all your mail is stored.
3. Create a new folder on the Desktop and name it however you wish (e.g. Inbox Old). It doesn’t need to have an .mbox extension.
4. In the Finder, go to ~/Library/Mail/POP-username@mailserver/INBOX.mbox/.
5. Move the files mbox and Incoming_Mail out of INBOX.mbox, into the Inbox Old folder just created on the Desktop. These files contain all the messages that were in the mailbox before the upgrade to Tiger, and maybe even some messages that had been deleted. mbox is the most important. Incoming_Mail may or may not be present.
6. Move any strangely-named Messages-T0x... folders to the Desktop (not into the Inbox Old folder). These folders are to be deleted after fixing the problem. They are temporary folders created during an import or an indexing process, and Mail should have deleted them when done. Their presence is a clear indication that something didn’t work as expected. If you’ve been using Mail after the conversion and have already tried to fix the problem by rebuilding the mailbox or something like that, they might contain messages that are neither in Messages proper nor in the mbox file, so keep them around until the problem is fixed.
7. Move everything else within INBOX.mbox, except the Messages folder, to the Trash.
The result of the above should be that INBOX.mbox contains the proper Messages folder only, and the Inbox Old folder on the Desktop contains the mbox and Incoming_Mail (if it exists) files only. Now, proceed as follows:
8. Open Mail.
9. The account’s Inbox should properly display in Mail as many messages as *.emlx files are in ~/Library/Mail/POP-username@mailserver/INBOX.mbox/Messages/. If that’s not the case, select the mailbox in Mail and do Mailbox > Rebuild.
10. In Mail, do File > Import Mailboxes, choose Other as the data format, and follow the instructions to import the Inbox Old folder that’s on the Desktop.
As a result of doing the above, some messages may be duplicated now. Andreas Amann’s Mail Scripts has a Remove Duplicates script that you may find useful.
Do with the imported mail whatever you wish. You may move the messages anywhere you want and get rid of the imported mailboxes afterwards.
If all is well and you don’t miss anything, the files on the Desktop can be deleted, although you may want to keep them for a while, just in case.
Take a look at the following article (also referenced in the thread I mentioned at the beginning of this post) to learn what you might have done before upgrading to minimize the risk of this happening, and what you may do after fixing the problem to avoid similar issues from happening in the future. DON’T do now what the article suggests, though, as that would make things worse in the current situation:
Overstuffed mailbox is unexpectedly empty
Ask for any clarifications or if you need further assistance.
Note: For those not familiarized with the ~/ notation, it refers to the user’s home folder, i.e. ~/Library is the Library folder within the user’s home folder.

Turns out that the program leaves metadata in your app data folder that is not removed upon uninstallation of the software.
This is incorporated to communicate with a file that uploaded into the ftp directory when publishing pages.

Just upgraded to Lion, can't open any pdf file downloaded from internet that was fine with Leopard. How can I overcome this obstacle ?

Just upgraded to Lion, can't open any pdf file downloaded from the internet that was fine with Leopard before. I just got a black screen when I clicked on a pdf icon on a given internet site, and same happened with several sites that I visited. How can I overcome this obstacle ?

Try two things with Safari not running:
1) Launch Adobe Reader, open its preferences, select the Internet category, and check the values under "Display PDF in browser using". If it's checked, try unchecking it.
2) Look in /Library/Internet Plug-Ins (at the top-level of your boot volume) for something names AdobePDFViewer.plugin. If you see such a file, try moving it to a folder named "Disabled Plug-Ins" (if such a folder exists) or onto the Desktop.
Then see how things work.

are you certain that you’ve completely downloaded the .pkg file — that the download didn’t end prematurely?
