Set filename for file download

Hi
i have a servlet that sends a file to the client to be downloaded. When the client requests the file the dowload dialogue pops asking if the user wants to download/open but the name of the file is always the servlet name were it originates. Is there any way to set the filename and extension in the servlet e.g ExampleResult1234.csv and send this to the client so that when the dialogue pops up it is set?
Current Servlet Code:
String output = "some data from database in csv format";
response.setContentType("application/binary");
response.getWriter().write(output);Thanks
David

It would be nice for the next person who needs help with this if you posted your solutions. :)

Any way to set up iWeb pages for file download / sharing?

I have been using .Mac Homepage to set up several web pages to share audio files with my clients. I have been able to set up a different web page for each client, each with their own password, with files there for them to download.
Is there a way to duplicate this using iWeb now that .mac homepage sites are going away? I don't want the audio to stream, I just want to make the files available for downloading, and don't see any page templates in iWeb '08 for file downloading.
I know that I can use mobileme's new file sharing feature to email links to individual files, but this doesn't work as well as having all the files downloadable on one or more web pages.

If you have all of the sites in one domain file you should be able to upload only the changed pages but it's been a while since I used 08 so don't remember. You can move each site into its own domain file so that only that site is edited and published. And if you're publishing directly to mobile me only the edited files should be uploaded.
I use iWebSites to manage over 75 individual sites.. It lets me create multiple sites and multiple domain files.
If you have multiple sites in one domain file here's the workflow I used to split them into individual site files with iWebSites. Be sure to make a backup copy of your original Domain.sites files before starting the splitting process and move it to another location on your HD until you're satisfied the separation process is completed and what you want.
This lets me edit several sites and only republish the one I want. Make sure you're running the lastest version of iWeb, 2.0.4 I believe.
An example of files set up for immediate download is Toad's Cellar. Each linked is linked to a zipped file which downloads when clicked on. The site could be password protected if so desired.

Drop-down Menu to Open URL for File Download

I am using Adobe Captivate 5.5 and was wondering if it is possible to create a drop-down menu that can be used to open different URLs for file downloads, kind of like the Attachments button Presenter has. Captivate seems to have a dropdown widget available but I can't tell if this would work for this purpose.

Hi Theo
You can use any composition to create a menu with setting for show target on rollover and then link targets to specific pages.

JSF error message: Automatic prompting for file download

This is a weird problem. I have a JSF application wherin I popup a new window on a submit button.
The window opens a test.jsf page that redirects the output to a servlet1.
Servlet then based on some parameters does a sendRedirectI() to different servlets out of context.
Now the issue is that when the output is redirected to out of context servlet, that returns a file download.
If in IE browser, if one does not do a setting of "Automatic prompting for file download", this window that I had opened on submit buttton vanishes in a jiffy. If the IE setting is done, it shows the file download correctly.
I would want to show the user some kind of message by which he/she understands that this IE setting has to be done.
I have tried several ways:
1. Javascript: window.onbeforeunload on the test.jsf so that when the window unloads i can show some message. But since test.jsf forwards to servlet1, the html page generated does not show my script.
2. I also tried checking if some windows registry can help me understand the setting.
3. I tried writing in response object the javascript and then redirecting it to servlet out of context. But I guess sendRedirect() does a new request, so this did not help.
Can anyone help? I am not sure if I am able to explain my problem correctly.
Yani

Here is the result.I used your code and it worked fine with IE setting Enabled. But when I tried to access the download servlet after opening a new window, it doesnt download the file.

Automatic prompting for file download

I am using a File Download Servlet. Theres a setting in IE under Securiy Settings --> Downloads--->Automatic Prompting for File Downloads.If I have this disabled, I am able to download the file.If its enabled, I am unable to download the file successfully. Anyone have faced this problem before?

Hello Matthew,
You should also change your temp directory to something woth no spaces, something like C:\temp.
Sapisnt sometimes has problems with the spaces in the temp path, and the Universal Installer nearly always
has a problem with this.

No. CSS is for presentation, but these parameters belong to
the HTML and
have to be written there.
BTW: The 'embed' element is invalid HTML. If you care about
valid markup
and your site doesn't have to be compatible with really old
browsers
like NN 4 or IE 5.5, then you should use the valid method
using 'object'

Java WebDynpro's and IE security settings for file download

We have a EP 7.0 SP13 environment on which we have deployed a number of own developed java webdynpro's. In some of these webdynpro's we provide the file download functionality. The portal and webdynpro's are used by both internal personnel and external customers.
On the other hand the default Internet security settings for Internet Explorer, disable "Automatic prompting for file downloads".
When a user, with these default security settings active, tries to use our webdynpro's file download functionality, the screen seems to refreshes but no file download starts. When (s)he retries, the session runs for some minutes and gives following error message:
"com.sap.tc.webdynpro.services.session.LockException: Thread SAPEngine_Application_Thread[impl:3]_20 failed to acquire exclusive lock on client session ClientSession".
This behavior is explained in SAPNote 1234847. Webdynpro provides a single-thread module, meaning a user session is blocked for the during of the request. And because the previous file download isn't yet completed the new try can't start.
Issue now, although the users IE settings allow file downloads and don't block pop up's, he can't download the file and even isn't made aware of the cause of the failure.
How can we avoid this issue, without having to communicate the
application requires specific browser settings?

Problems with signed Applet for File Download under JRE 1.4 (works with 1.3

Dear all,
i encountered a very strange behaviour with JRE 1.4x. A signed applet used for file download worked on all platforms (Windows NT, 2000 and XP wth/wthout SP...) until I installed JRE 1.4.x (1.4.1 or 1.4.2)
I get an EOFException when downloading binary files (for ASCII it works fine) when trying to readByte() from a DataInputStream. But not immideately, but after x bytes in the while-loop. Security is fine (I know there have been changes to that in jre 1.4, the applet itself can be started an runs with ASCII files for transfer)
Does anyone know, what has changed in jre1.4.
As I said, it works fine under jre 1.3.x
The relevant code is below: byte bt = dis.readByte(); causes the error
try{
// Get URL from Server
URL uFile = new URL(sFilename);
sThisURLFile = uFile.getFile();
Integer inte = new Integer(i);
//open input stream for the file on server
DataInputStream dis = new DataInputStream(new BufferedInputStream
(uFile.openConnection().getInputStream()));
//open output stream for the file on local drive
String sFilenameOnly = sThisURLFile.substring(sThisURLFile.lastIndexOf('/')+1);
int iDotPos = sFilenameOnly.lastIndexOf(".");
String sExt;
if (iDotPos > 0) {
sExt= sFilenameOnly.substring(iDotPos);
} else {
sExt = "";
File fileOut = new File(sDownloadDir + sThisURLFile.substring(sThisURLFile.lastIndexOf('/')+1) );
DataOutputStream dos = new DataOutputStream(new
BufferedOutputStream(new FileOutputStream(fileOut)));
//read one byte from input stream, and write that byte to output stream
long nByte = 0;
int iCnt = 0;
iFilesizeDone ++;
while (nByte < iFilesize){
String sErrPs = new String();
try{
sErrPs = "00";
byte bt = dis.readByte();
sErrPs = "01";
dos.writeByte(bt);
} catch (EOFException ee)
System.err.println("internal EOFException: " + ee.getMessage());
System.out.println("Error Filesize is " nByte " of " iFilesize "---" + sErrPs);
break;
nByte++;
iFilesizeDone ++;
iCnt ++;
if(iCnt >= 10240) {
ShowProgress(nByte, iFilesize, iFilesizeDone, iFilesizeTotal); // repaint does not work during init-procedure
iCnt = 0;
line = "Progress: Total: " + ((iFilesizeDone*100)/iFilesizeTotal) + " perc, " + iFilesizeTotal/1024 +" kbytes" ;
labLine.setText(line);
//dos.flush(); // improves Client performance (Agent-Call!)
dis.close();
dos.close();
}// End try
catch (EOFException ee)
System.err.println("EOFException: " + ee.getMessage()e);
catch (SecurityException se)
System.err.println("SecurityException: " + se.getMessage());
catch (IOException ioe)
System.err.println("IOException: " + ioe.getMessage());

perhaps they've changed something with the file blocking.
btw, you should try to use something like this
DataInputStream dis = new DataInputStream(is);
byte[] buffer=new byte[8192];
int numBytesRead;
while ( dis.available()>0 ) {
numBytesRead = dis.read(buffer);
}

Peformance Turning for File Download / Upload with Enabled SharePoint Audit

Greetings all, may I ask your help for Peformance Issues?
Background:
I tried to create a ASP.NET Web Page to download/upload/list SharePoint file and deployed to IIS website in same application server (will NOT use web part as some users are NOT allowed to direct access confidential workspace)
Besides, for Audit Log record purpose, the page will impersonate (without password) the logged in user:
SPUserToken userToken = web.AllUsers[user].UserToken;
SPSite s = new SPSite(siteStr, userToken);
For File Listing, the web service can provide fast response, and we are using service A/C for connection (as no auting for listing, but require audit for file download upload)
Several implemeation options tested for File Downloiad / Upload, but issues occured and finding listed below:
Issues
1) SharePoint Object Model
When I open Site (using new SPSite), it's too slow to respond. (under 1s for all operations, but require 10~50s for open SPSIte. e.g.
using(SPSite s = new SPSite(siteStr) //50s
How can I download/upload file without open SPSite object (using SharePoint object model, but user token should be kept to allow SHarePoint identifiy user actions. e.g. Updated by Tom, NOT system administrator)?
2) SharePoint default web service
For file download, I tried to use SharePoint Web Service for download file, it's quick but how can SharePoint record the audit log to downloaded user, and not service A/C? ( e.g. View by Tom, NOT system administrator)
With Windows SSO solution, please note system should NOT prompt to ask user password for use impersonation
3) HTTP Request API (for file download)
As mentioned in point 2, if the system cannot get password from user, SharePoint also recorded service A/C in audit log... ><
Thank you for your kine attention.
.NET Beginner 3.5

Thank you for prompt response, please find my reply with Underline:
Hi,
Maybe I'm not quite clear about the architecture you have now.
Is your asp.net application deployed in separate IIS site but in the same physical server as SharePoint?
Yes
"we are using service A/C for connection", can you please explain the 'A/C'?
Domain User, Local Admin and also SharePoint Service Admin A/C
Opening SPSite is relatively slower but shouldn't take 50 sec. However it depends on your server hardware configuration. You should meet the minimum hardware requirements for SharePoint.
Assigned double resources based on minimum hardware requirements.
For details, 50s is the load test result. But for other SharePoint operation, it takes around/under 3s reponse time.
Are you using SharePoint Audit log? Exactly If so then why don't you just put the hyperlink to the documents in your asp.net page. User maybe have to login once in SharePoint site but
it depends on your security architecture. For example if both of your sites in local intranet and you are using windows integrated authentication, SSO will work automatically User is NOT allowed
to access SharePoint site/server (not implemented for sepreate server yet, as performance issues occured for
separate site in same server) directly from Internet, the
middle server with web interface created for user request.
Whatever I understands gives me the feeling that you download the file using HTTPWebRequest C# class. However regarding security it depends on how authentication is setup in asp.net web site and in sharepoint. If both site uses windows integrated security
and they are in the same server, you can use the following code snippet:
using (WebClient webClient = new WebClient())
webClient.Credentials = System.Net.CredentialCache.DefaultNetworkCredentials;
webClient.DownloadFile("file ur in sharepoint", "download directory");
Thanks, will try and reply later
But still, as I've mentioned, not quite clear about the whole architecture.
A) Request Handling
1) User use browser to request file listing and/or download file (hereafter called: File Download Request) from custom ASP.NET page (Let's say In Server 1, IIS 1)
2) ASP.NET　page or File Handler ashx (Server 1, IIS 1) call custom web service, SharePoint deault/OOTB web service or using SharePoint Object Model to access SharePoint Document Library (in Server 1,
IIS 2)
3) Both SharePoint and IIS Web Site
(Server 1, IIS 1 & IIS2) using the same service A/C
4) The web service , File Handler return file obeject to IIS1
5) IIS 1 reply File Download Request to user
B) Application Architecture (In testing environment)
1) no load balancing
2) 1 DB server (Server 2)
3) 1 Application Server (with IIS 1 - ASP.NET, IIS 2, SharePoint Web Site with default SharePoint Web Service, IIS 3 SharePoint Admin Site & IIS 4 Custom SharePoint Web Service)
4) Sepreate AD Server (Server 3)

KM Document iView for file download - filename

Hello,
we have a hyperlink on our portal logon page for downloading a word document. This link points to a KM document iView. The iView has the property "Path to Document" set to the document in the KM.
By clicking the link, a file download pop-up appears. But the filename of the downloadable file is the path of the iView - and not the real name of the document.
Is there any possibility to get the real name as name for the downloadable file? Or should we use another iView?
Any hint is appreciated!
Best regards,
Matthias

Sorry Tom!
Your problem seems to be different, I've no idea.
But we already fixed our problem, I forgot to post. Here's our solution:
The solution was to create a KM Docs iView with anonymous authentication schema pointing to the download file. Then we created an URL iView pointing to this KM Doc with appending the filename AGAIN to the URL (because otherwise the iView ID will appear as filename). In the page a hyperlink now is pointing to the URL iView and after clicking it, the download starts with the correct filename.

To display non US-ASCII filename in file download dialog - Help Needed

Hi,
Our application supports to upload a file with name in chinese/japanese language. When user tries to download filedownload dialog box is appearing with the filename as junk characters.
How to solve this issue to display the filename as uploaded.
Thanks in advance
~kans

bsampieri, issue is in display of the file name in
file download dialog.
~kansI understood that, but my thought was that the HTTP headers content type containing a charset of UTF-8 might help. I don't know for sure, but otherwise, I don't know how to get the browser to otherwise not assume ASCII.

Implementing file "Save as" functionality for file download api

Hi,
I want to implement File Download (Open/Save as/Cancel dialogue box) programmatically.
I am displaying list of links to document in a web dynpro table and I dont want to set IWDResource data for all entries in table.
And on Click of a button/link to action, I want to open up a File download box.
I have URL to the file with me and I'm able to convert it to IWDResource.
Following are the things available with me for a selected file:-
-- Complete name of file along with extension
-- byte[] of file.
Please help.
Thanks and regards,
Amey Mogare

I could achieve it with following code:-
     String l_str_LinkValue = null;
     String l_str_LinkName = null;
     URL l_url = null;
     InputStream l_is_inputS = null;
     try {
          l_str_LinkValue = wdContext.currentCtx_vn_KmFolderDataElement().getLinkValue();
          l_str_LinkName = wdContext.currentCtx_vn_KmFolderDataElement().getLinkName();
          l_url = new URL(l_str_LinkValue);
          l_is_inputS = l_url.openStream();
          IWDResource res = WDResourceFactory.createResource(l_is_inputS, l_str_LinkName, WDWebResourceType.UNKNOWN, true);
          if(res != null){
               wdContext.currentContextElement().setFileRes(res);
          }else{
               myMessage.reportException("Unable to create file", true);
     catch (MalformedURLException mfurle) {
          myMessage.reportException("MalformedURLException : "+mfurle.toString(), true);
          wdContext.currentContextElement().setFileRes(null);
     catch (IOException ioe) {
          myMessage.reportException("IOException : "+ioe.toString(), true);
          wdContext.currentContextElement().setFileRes(null);
     catch (Exception e) {
          myMessage.reportException("Exception : "+e.toString(), true);
          wdContext.currentContextElement().setFileRes(null);
