file download
hi everybody, I want to provide the ability to my webapp's users to download a .java file clicking on a html link. My problem is that I have no save as dialog box, Im redirected to the content of my file. I changed my web.xml mime type but still the same. Any idea? _ MSN Messenger : personnalisez votre messagerie instantanée ! http://g.msn.fr/FR1001/866 - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

Re: file download
If you serve the java file through a servlet you can set the 'Content-disposition' header on the response to 'attachment'. dumbQuestionsAsker _ wrote: hi everybody, I want to provide the ability to my webapp's users to download a .java file clicking on a html link.

SSL on tomcat breaks file download
I created a JSP web application that allows user to dynamically generate and download excel files using POI/HSSF. I use the following lines to store the excel file in my application directory under a directory titled xlsreports: nextXLSName = MiscUtil.getNextXLSName(); //gets the next file name by querying the database. report.writeFile(WebappPrefs.getRptPath(session.getServletContext()) + nextXLSName); The above lines seem to work because I find the generated file in the correct folder with the correct time stamp of when I tested the JSP. I then use the following line of code to send the user the file: jsp:forward page=%= \xlsreports/\ + nextXLSName % / This has always worked flawlessly until I implemented SSL on Tomcat. Now, IE tells me that the requested site is either unavailable or cannot be found. Any ideas why implementing SSL would break this or how to fix it?

Servlet coming as file download
Hello, I have a Apache 2.0.50 with an active mod_deflate connecting to Tomcat (4.x) via mod_jk2. After I activated deflate, sometimes when I call a servlet IE doesn´t open the page with the servlet response, but a file download window as if I was trying to download a file named 'servlet'. Can anyone please suggest a solution ? Thanks
apache2/mod_jk/tomcat4 - file download / special characters in filename
Problem: In my tomcat webapp a servlet manages a filedownload. Clicking on a file-link results in the browser's save as dialog. Using tomcat alone (port 8080) everything works fine. Special characters (like German umlaut) are shown in ISO-8859-1. Apache2/mod_jk seems to change the charset to UTF-8, e.g. täst.txt looks like tät.txt. Code: response.setHeader(Content-Disposition, attachment; filename= + file.getName()); response.setContentLength((int)file.length()); response.setContentType(application/octet-stream); response.setHeader(Content-Transfer-Encoding, binary); I tried also: response.setContentType(application/octet-stream; charset=ISO-8859-1); or String tmpName = new String(f.getName().getBytes(),ISO-8859-1); response.setHeader(Content-Disposition, attachment; charset=ISO8859-1; filename=+tmpName); or response.setHeader(Content-Transfer-Encoding, ISO-8859-1); Configuration: - Suse 8.2 - Apache2.0.48 - Tomcat4.1.18 - mod_jk - $tomcat_home/bin/catalina.sh: export CATALINA_OPTS=-Dfile.encoding=ISO-8859-1 -Duser.language=de -Duser.country=DE Who can help ?

Re: apache2/mod_jk/tomcat4 - file download / special characters in filename

RE: HELP: Servlet File Download solution.
This probably doesn't matter, but try this instead:
response.setHeader(Content-Disposition,
attachment;filename=\ + myFileName + \);
// Removed the space in between attachment; and filename
response.setContentType(application/octet-stream);
// I don't think you need to specify the filename again
Using the above seems to work for me, but I'm not sure if a user with
IE5 has tried it. What happens when you use it in IE5? Error message?
Data output to the screen? Empty file?
It might be a MIME problem also.

Re: File download impact JSP running
Hello,
I know nothing about Content-Disposition. In fact, the only thing I know
is that we never needed/used it ;-)
Maybe it is too obvious, but I suggest you to try
response.setContentType() instead.
Anyway, I will try to get a code snippet from one of our apps a bit
later for you.
Hope that helps a little bit.

Re: File download impact JSP running
Hi!
Sorry about my previous response: I missed the important point.
Here is what the RFC says about Content-Disposition (two fragments of
RFC 2616).
Anyway, the important part is that you SHOULD NOT send your file AND a
web page after it.
In your code snippet, you loop over the file, sending it, and then you
forward to a JSP file. That is, simply, not possible.
If you want to do the same thing which is implemented in, i.e.
sourceforge (a page appears and a file starts downloading, more or less
at the same time), I suggest you to read the HTML code they have.
Good luck!
Antonio Fiol
15.5 Content-Disposition Issues
RFC 1806 http://www.faqs.org/rfcs/rfc1806.html [35], from which the often
implemented Content-Disposition
(see section 19.5.1) header in HTTP is derived, has a number of very
serious security considerations. Content-Disposition is not part of
the HTTP standard, but since it is widely implemented, we are
documenting its use and risks for implementors. See RFC 2183
http://www.faqs.org/rfcs/rfc2183.html [49]
(which updates RFC 1806 http://www.faqs.org/rfcs/rfc1806.html) for details.
19.5.1 Content-Disposition
The Content-Disposition response-header field has been proposed as a
means for the origin server to suggest a default filename if the user
requests that the content is saved to a file. This usage is derived
from the definition of Content-Disposition in RFC 1806
http://www.faqs.org/rfcs/rfc1806.html [35].
content-disposition = Content-Disposition :
disposition-type *( ; disposition-parm )
disposition-type = attachment | disp-extension-token
disposition-parm = filename-parm | disp-extension-parm
filename-parm = filename = quoted-string
disp-extension-token = token
disp-extension-parm = token = ( token | quoted-string )
An example is
Content-Disposition: attachment; filename=fname.ext
The receiving user agent SHOULD NOT respect any directory path
information present in the filename-parm parameter, which is the only
parameter believed to apply to HTTP implementations at this time. The
filename SHOULD be treated as a terminal component only.
If this header is used in a response with the application/octet-
stream content-type, the implied suggestion is that the user agent
should not display the response, but directly enter a `save response
as...' dialog.
See section 15.5 for Content-Disposition security issues.

Re: File download impact JSP running
Hello
The RequestDispatcher.forward method 'should be called before the response
has been committed to the client' as quoted from:
http://jakarta.apache.org/tomcat/tomcat-4.1-doc/servletapi/index.html
I think your code is breaking that rule.

Hello All,
I use below a set of commands to download a file, after the file is saved
into local disk, the current JSP page (Jreport_main.jsp) could not work
correctly. After the current page is refreshed, it can work again. Does
setting header in response impact the jsp running? Could please give some
advice? Thanks.

[OT] cache problems with IE after file download...could it be tomcat?
Hi everyone: This is more related to Java than tomcat i guess! But any input would be greatly appreciated. This is a question that has been around for a while now...I tried looking up the forums on Sun's website...but could not really find a solution to solve my problem...so here goes... I have implemented a file download bean which sends out binary data to the browser. The bean is instantiated by a JSP page. To make sure browsers don't cache response I do: response.setHeader(Cache-Control, no-cache); response.setHeader(Pragma, no-cache); response.setDateHeader(max-age, 0); response.setDateHeader(Expires, 0); while sending out the file and on every other JSP page on the site. However, for some reason the JSP page accessed immediately after downloading a file contains portions of a binary stream on the top of the page followed by HTML. I am confident the server is not resending the data again...(confirmed it with ethereal and nescape works too)...so I dont know what I am doing wrong...or what I should do to get it right...Any suggestions ot opinions on this? Note that the headers work perfectly fine while navigating through JSP pages. Thanks Prashanth __ Do you Yahoo!? Yahoo!

Weird error using file download
I got a very weird error and here is the situation: The app I used: tomcat 4.06, phoenix web browser 0.3, ie6.0 Here is the problem: When I set up an application in tomcat (with BASIC AUTHEN), phoenix could download all binary files (.exe, .pdf, etc...) fine from Tomcat server. Then I tested with IE6.0, and I got error (server could not find the file or something). However, IE6.0 could download text file ok without any problem. Ok, so I came back and delete the file index.html in the application, and I can download the file fine. Isn't this strange? But that's not all yet. I want to serve files using a servlet wraper. Basically send back the binary with the right content type. Mozilla/phoenix can download without any problem. But IE6.0 complain with the same error before. So, somehow the index.html file and the servlet have something in common that make IE not working while it works without the index.html and statically. Well, want another strange thing? I could not find anyone complain about this, or even ask any question about this in newsgroup or apache site. And I can produce consistently using different machine. Anyone have any idea? Is it Apache Tomcat or IE error? Or both? Or it's me? I am sure Tomcat can be changed to work, since statically served page works. And I am sure IE can be changed to work, since Mozilla works all the time. Actually, I found any article in the newsgroup on Google with a similar error, but very different situation (IIS server). And the problem is in the expiration of a page. If some page has instant expiration, then IE6 has problem getting it. It could be the same problem. Coudl someone help me out here since IE has 95% of the market share? Thank you very much in advance.

Re: File Download and then Reloading a page
I would like to be able within a servlet to launch a file download and just after reloading a jsp page( =The servlet generates two response ). Is it possible ? No, but you can give a JSP/HTML page in response that will have JScript function that opens another page that will be just a download (the URL will point to the document or to a Servlet that will in response give the document). The function should be in onLoad attribute of the body tag. In other words, any such forking must be done on the client side - HTTP is one-request-one-response model. Nix.
IIS - jsp file download on port 80
First, thanks in advance for any help with this... I've gotten Tomcat 4.0.4 set up and everything works well if I connect to port 8080. I'd like to be able to serve servlets and jsp's transparently to users over port 80. However, if I connect through port 80 and try to grab a .jsp file all I get is a download prompt asking me if I want to save the file to my hard drive. (You can see for yourself: http://128.200.156.162/home/jsp-files/fruit.jsp http://128.200.156.162/home/jsp-files/fruit.jsp ). (you can also see that Tomcat works on port 8080: http://128.200.156.162:8080/jsp-files/fruit.jsp http://128.200.156.162:8080/jsp-files/fruit.jsp ) I'm not sure what needs to be changed. Do I need to add an application mapping for .jsp's to the default web site in IIS? If that's so, I'm not sure what to map it _to_. Would it be isapi_redirector.dll? I tried setting Tomcat to run on port 80, but Tomcat just breaks. Is the problem that I'm using the warp connector? Should I be using something else? I've put a copy of all the Tomcat configuration files in: http://128.200.156.162/home/jeff/tomcat/conf/ http://128.200.156.162/home/jeff/tomcat/conf/ . As far as I can tell, everything is set up correctly... I took out ajp12 because it isn't used in anything. Removing it didn't seem to affect anything... I'll be happy to summarize and post the solution to the group, once it's worked out. And again, thanks for any help!

Re: IIS - jsp file download on port 80
Try adding a application mapping in your IIS console. (IIS console -- Home Directory -- Configuration App Mapping), I'm using IIS 5.0 in win2k professional. In this console add the .jsp entension and map it to isapi_redirect(or).dll where ever it is stored. That should work. Also, check to see if your web application has script and executable access.

Re: File download with Tomcat 4.0.2
Hi Alex, I think that's actully up to the browser to determinate wheter the browser should display the data, if a helper application should do so or if the user should be prompted to download the file without displaying or executing it. So, in other words, what you need to do is to say on the page which links to the file that if the browser just displays the data you need to press [ALT] on Mac while downloading (and is it [SHIFT] on Windows?). However if your userbase i pretty constant like on an intranet you could send out instructions that files with the extension fls shouldn't be displayed in the browser but instead should the user be prompted for download (or maybe even more convinient - opened in the right application).

Re: File download with Tomcat 4.0.2
yes, define a mime-mapping is this not a common mime type (one you've made up yourself)? If so, many browsers will display anything they perceive as text data right in the browser itself by default. you're running into a somewhat complex interaction of client browser software and server software. Try the mime-mapping and see what happens. fillup On 5/31/02 2:34 PM, Alex Roussev [EMAIL PROTECTED] wrote: Hello, How do I force Tomcat to serve a file as a download, instead of displaying it in the browser?

Without being an expert on TomCat, I'd say straight away that this is a MIME error. You need to set the MIME for .csv files to something that's not parsed by the browser, like, application/x-whatever. Fiddle around with that. I think the MIMES are in the server.xml file.

In a servlet 2.3 environment, the default content type is not allowed to be set on the download. You must declare it yourself (see below). Is there any reason for this? Can I change the configuration? Yes. Yes. Is this a MIME type problem? Yes. You can declare the appropriate content types for your files by using the mime-type declaration like this in your web.xml file: mime-mapping extensioncsv/extension mime-typeapplication/octet-stream/mime-type /mime-mapping The other important issue is what your *browser* thinks a particular file type should be. Netscape Navigator is usually pretty good about respecting the Content-Type header sent by the server, while IE tends to make its own assumptions about the file type, no matter what yo do on the server side.

The only difference is going from TC3.2 on windows to TC4.0 on HP Unix. I would think that the IE would be making the decision on how to handle the file by the extension name but it is not. technically speaking it should (and by the sounds of it is) be looking at the mime type. Is MIME type something you can configure on Tomcat? Yes -- either in Tomcat or in your application web.xml. These MIME type settings are used by Tomcat when it serves static resources, or you can look them up yourself via ServletContext.getMimeType(). For Tomcat 4 (the technique is different on 3.x and I don't recall the details), you can set MIME types globally by modifying $TOMCAT_HOME/conf/web.xml. For all versions of Tomcat, you can define MIME types in your own web.xml file by adding mime-mapping elements. For example: mime-mapping extensionhtml/extension mime-typetext/html/mime-type /mime-mapping is how Tomcat knows what content type to set on HTML pages. To trigger a download dialog for CSV files (the original question on this thread), you need to configure a MIME type that your browser doesn't recognize -- usually application/octet-stream will work. On the other hand, you can configure things to fire off Excel automatically, as well (if your browser is set up that way) by saying something like: mime-mapping extensioncsv/extension mime-typeapplication/msexcel/mime-type /mime-mapping (Check the file types configuration in your browser to find out what the correct MIME types should be.)

one simple thing, just try it out on ur windows machine, in browser window...location bar... write the url u r trying to open thru anchor link.. i.e. in browser window location bar : http://servername/direcorypath/filename.csv and see, if it opens up the file in browser or pops up 'save as' dialog box. If it shows u save as dialog box, then that means, your browser doesn't support interpretation/opening of that file into it. regards, Chintan -Original Message- From: Evan Swanson [mailto:[EMAIL PROTECTED]] Sent: Wednesday, October 24, 2001 9:01 PM To: '[EMAIL PROTECTED]' Subject: File Download - CSV question I wrote an application that for Tomcat 3.2 running on window.

I remember vaguely that this kind of stuff can also be working in one browser and not work in another one... regards Alexander -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]] Sent: Tuesday, September 11, 2001 11:53 PM To: [EMAIL PROTECTED] Subject: file download servlet I asked this question before, but I didn't get any reply. I post it again in hope someone could give me some hint. I have a file download servlet serves web browsers. request to file is like this http://192.168.1.105/download/servlet/download?filename=song.mp3 The file on the server side is song.mp3. But the file got download to browser is the servlet name instead. :( I heard i need to use the HTTP header res.setHeader(Content-Disposition,attachment; filename=\ + downloadFile + \;); Is Content-Disposition a standard header in HTTP spec? I heard i should use this whenever I don't want the content display on browser (force Save as Dialog box) Why everytime I download a file from the web server like song.mp3. there is no such HTTP header from web server? -- Content-Disposition I think web server is just like a download servlet. It sends raw bytes to web browser. After browser get the bytes, It will not konw what name the file should save as. Web server must send some kind of HTTP header to tell web browser what file name the file is saved as. right? How exactly is web server instruct web browser to pop up Save as Dialog box (on unknown mime type) and save the file with name = filename on server? Does web server use any special HTTP Header (like Content-Disposition) thanks. __ Do You Yahoo!? Get email alerts NEW webcam video instant messaging with Yahoo! Messenger http://im.yahoo.com
RE: setContentType / File download
Please help, we encounter similar problem but with IE5.5 only (no problem
with all Netscapes, and IE5.01 and below versions). Seems MS has changed
something in IE5.5

Subject:setContentType / File download
Hi tomcat-user,
i have some troubles using the setContentType method.
I want to generate a CSV file of my database data and send it to the
browser. the browser should then say "save file as filenam.csv" ...
what i do is:
response.setContentType("application/msexcel;name=\"TUInventory.csv\"\nConte
nt-Disposition: attachment;filename=TUInventory.csv;");
this works for netscape browsers, but ie wants to save index.html.
any tips?
Gerd

On the cocoon-users there's been a discussion about the following code
response.setHeader("Content-Disposition", "inline;filename=kluge.txt");
they said it was an "unofficial" IE header for the same purpose. haven't tested it
myself,
but looks like we now have two complementry solutions, for
IE and NS :-)

RE: setContentType / File download
oh goodie... someone else who has this problem!
I battled this one for a long time and finally, microsoft sent out
the following article on their web:
http://support.microsoft.com/support/kb/articles/Q279/6/67.ASP
And here is another article which I find interesting:
http://support.microsoft.com/support/kb/articles/Q267/9/91.ASP
My guess... M$ tried to fix the bug in the later one but screwed up
somewhere along the line which resulted in the first one.
Anyways. This is due to one of the very few *acknowledged* (by
Microsoft I mean) bugs in IE 5.5 so sorry, nothing you can do about
it! but on the bright side... it's nothing you did wrong either ;o)
(this is what I'm trying to convince myself of after spending waaayyy to
much time on this).
Regards, Stefan.
p.s. If you're using tomcat I'd suggest you use this code instead of
what you have (just for readability):
response.setContentType("application/msexcel");
response.setHeader("Content-Disposition","attachment;filename=TUInventor
y.csv");
p.p.s.
I solved this by checking the "User-Agent" header in the request and if
it was IE5.5 I don't set the Content disposition header. This pops up
the Save file/open dialog box but if you choose to save you'll get a
garbled name... but at least you'll get the file!
