File Download and Mime-Types

I have some files (txt, xls, rtf, pdf) that need to be downloaded from our site. I
have an http link to the files on the web page. I've set mime-types for each file
type in web.xml for that web app. I'm using WLS 6sp2 on Windows 2K. I'm using an
MVC model for the application with a Controller servlet. Every time anyone tries
to click on the link and download it, the Contorller kicks them to a default page.
Can anyone help?
Thank you.

Go to IIS Management console. At the server level, go to MIME Types. Add a new MIME type:
File name extension:
.mp4
MIME type:
video/mp4
Restart IIS (can't remember if this is required).

How To Get FileType and MIME Type from a File

Hi,
I am using following ways to get FileType and MIME Type.
I am able to get file type, but I am getting MIME Type as */*
Can any one please let me know how to get MIME Type, but it should not be time consuming process.
For File Type I am using following Code:
private String getFileData(InputStream inStream) {
fileName = C:\temp\temp.tiff
String filePath = Util.createTempFile(fileName);
RandomAccessFile raf = new RandomAccessFile(filePath, "rw");
while (inStream.available() > 0) {
     byte[] buf = new byte[inStream.available()];
     inStream.read(buf);
     raf.write(buf);
inStream.close();
raf.close();
File file = new File(filePath);
JFileChooser chooser = new JFileChooser();
String fileType = chooser.getTypeDescription(file);
file.delete();
//MIME Type I am getting from
DataHandler data = new DataHandler(new DocumentSource(inStream));
data.getContentType();
data.getContentType() is not working well in all cases.
Can any one help me on this.
Thanks in advance,
Ram.

//MIME Type I am getting from

data.getContentType();
data.getContentType() is not working well in all cases.That's because there's no way to get MIME type of all files on all filesystems.

Trying to embed a video file in HTML5: ERROR=No video with supported format and MIME type found?

Hello all!
I am desparate for a solution. I am testing my site on Firefox and Explorer and still no sign of a functional video yet.
Firefox: I get the error: No video with supported format and MIME type found.
Explorer: I just get a distorted layout.
Here is the code I am working on:
<table id="Table_01" width="480" height="801" border="0" cellpadding="0" cellspacing="0">
    <tr>
        <td colspan="6">
            <img src="images/Video_01.jpg" width="480" height="114" alt=""></td>
    </tr>
    <tr>
        <td rowspan="3">
            <img src="images/Video_02.jpg" width="52" height="486" alt=""></td>
        <td colspan="4">
           <video controls width="376" height="221">
             <source src="C:\Users\aalmeida\Videos\AEMC PEL 103 6 Channel, Power & Energy Logger - with Display (Part 1).mp4" type="Video/Mp4"/>
             <source src="C:\Users\aalmeida\Videos\AEMC PEL 103 6 Channel, Power & Energy Logger - with Display (Part 1).webm" type="Video/WebM"/>
             <source src="C:\Users\aalmeida\Videos\AEMC PEL 103 6 Channel, Power & Energy Logger - with Display (Part 1).oggtheora.ogv" type="Video/Ogg"/>
             </video>
Please tell me that there is something missing in the code. I have spent a lot of time uninstalling-updating Firefox plugins, added MIME types in the Internet Information Manager (I'm on Windows 7)
and seriuously hit a dead end with this!
Any advice would be muchly appreciated!!!
Thanks

As Jon said, you must declare the page as HTML5.
And your server may not be set up to deliver video as a binary file if it is an .OGG file. I have not seen this problem with .MP4 or .M4V in the past, but every server is a little different.
To add a MIME type, you need to change your .htaccess file on an Apache server thusly:
AddType audio/ogg .oga
AddType video/ogg .ogv
AddType application/ogg .ogg
AddHandler application-ogg .ogg .ogv .oga
Additionally, MIME types can usually be changed on a server's Control Panel. One can also ask one's hosting provider to do this as well.
Firefox makes it necessary to use OGG files. Webkit-based browsers will deal with .M4V or .MP4 and I understand Internet Exploder will work with the latter two as well.

Image size and mime type.. non-java guy needs help

Image size, mime type.. non-java guy needs help
Im not at all familiar with java so this is really weird for me to work out. I?ve been doing it all day (and half of yesterday).
Im trying to write a custom clodFusion tag in java that gets the width, height, size and MIME types of a given file. I?ve been trying to get it to work on the command line first. I can get the width and height but cant get the size and the MIME type.
Here is what I got
/*import com.allaire.cfx.*;*/
import java.awt.image.renderable.*;
import javax.media.jai.*;
import com.sun.media.jai.codec.*;
import java.io.*;
import java.util.*;
public class ImageInfo {
private RenderedOp image = null;
private RenderedOp result = null;
private int height = 0;
private int width = 0;
private String type = "";
private String size = "";
public void loadf(String file) throws IOException
file = "80by80.jpg";
FileSeekableStream fss = new FileSeekableStream(file);
image = JAI.create("stream", fss);
height = image.getHeight();
width = image.getWidth();
System.out.println(height + "\n");
System.out.println(width);
System.out.println(type);
public static void main(String[] args) throws IOException {
ImageInfo test = new ImageInfo();
test.loadf(args[0]);
can anyone please help me out to modify the above so I can also print the mime type and the file size to screen.
thanks for any help

any suggestions?

Powerpoint uploads and MIME types

I am building an application to upload PPT files. I want to
test the
incoming filenames to see if it *is* a PPT file, but cannot
find a MIME type
for it. How should I do this so that I only allow such files
to be
uploaded?

OK - here's the skinny:
PPT extension files have a MIME type (PC or Mac) as stated.
PPTX extension
files (PC or Mac) have a MIME type as shown in the line in my
code below -
if (($_FILES['uploadfile']['type'] ==
'application/vnd.ms-powerpoint') ||
($_FILES['uploadfile']['type'] ==
'application/vnd.openxmlformats-officedocument.presentationml.presentation'))
This test appears to work as desired. Why would I not want to
use it to
filter all but Powerpoint files?

No video with supported formate and mime type found

I am able to view videos on all but 1 website: http://www.start-american-sign-language.com/free-sign-language-asl1.html
When I view that page, the video box only shows the x with "no video with supported formate and mime type found" being displayed.
I have updated to the most recent palemoon (25.3.0) and have the following plugins installed
DRM 9.0.0.4503
Shockwave flash 16.0.0.305
Silverlight 5.1.30514.0
VLC Web Plugin 2.2.0.0
Windows media Player Dynamic Link LIbrary 3.0.2.629
I have cleared my cache and cookies, and am unable to view the video in question. If I go to https://www.youtube.com/html5, it indicates that I have an operable Webelement player and Web VP8, and all others are exclamation points.
Does anyone know why I can't watch the (mp4) video(s) in question? I have turned up no viable solutions using the forums or google.
Thanks!

This happens when there is no support in your Windows XP version to play any of the media file formats that the website offers with the HTML5 media player (i.e. not a Flash player is used, but a video tag).
That are MP4 files with type="video/mp4"
*VLC shows: Codec: H264 - MPEG-4 AVC (part 10) (avc1)
You might be out of luck on Windows XP and your only option would be to use an external media player and paste the links in its location field.

FireFox 4 and earlier versions will not install on my Windows Vista, 64 bit computer. The file downloads and the file extracts but I never make it to the installation wizard.

I have tried to download FireFox 4 and earlier versions from several different website, thinking the files might have gotten corrupted, and each time I download the file the exact same thing happens, the file downloads and the file gets extracted but when the extraction completes the small window dissappears and nothing else happens.
My machine is a Windows Vista 64 bit system and I've tried downloading the file with my 32 and 64 bit Internet Explorer but nothing seems to work. Can someone help me please because I would love to be able to completely delete I.E.

Hi, thanks for your Flash file info. Well you must have been doing it right, since all of your Flash files for IE and FF are correct.
The SWF plugin for FF and the SWO for IE are also correct.
You shouldn't be having any problems with Flash Player.
What you can try is to turn off the hardware acceleration feature. Go to any video, like youtube and right click on the video and click on Settings. Display Settings is where you will UN check hardware acceleration.
See if that helps. Let me know.
Thanks,

Large file size and fuzzy type

I'm new at using FCE2 and composed my first short 4 minute video. It includes a still image, a PSD layered file which I discovered was quite handy, a few clips and type using the type generator. I exported it to QuickTime movie. Three observations: I was floored by the nearly 1GB size, fuzzy type, and the file on the hard drive says it's a FCE movie inclusive of the little FCE icon by the file name. I was expecting to see a QuickTime icon with file name and the type of file is a QuickTime movie. Is all this normal? I'm very disappointed in the fuzzy type. Oh, also, the still image became blurry. Why?? Just so you know, the still image was a special file 640x480 with a pixel aspect ratio of D4/D16 Anamorphic
I saved the project under a new name and redid it taking out the Photoshop image, removing it from the bin also, and the new movie exported even larger, over a gig in size. Huh??

Thanks for the reply Tom. After I posted the first time I went to the Finder, Get Info, and I saw that I could change the 'Opens with' to QuickTime and therefore it became a QuickTime file. About that Anamorphic business I read a 'how to' on dealing with images before bringing them into video. The tip says in the 'New' file dialogue box to choose 640x480 size and in the pull down menu at the bottom where you can choose the 'Pixel Aspect Ratio' it was suggest to use that Anamorphic setting. I did it but it certainly didn't look right but I went with it.
Again after I posted I looked at the Format of one of the clips and saw the size to be 720x480, Compressor is DV/DVCPRO-NTSC, Pixel Aspect is NTSC-CCIR 601, Anamorphic field is blank. I'm running Photoshop CS2. So I went back there and created a new blank file to use a template for dealing with stills but this time I used the Preset pull down menu and chose NTSC DV 720x480 with guides and the Pixel Aspect Ratio automatically loaded D1/DV NTSC (0.9), clicked Ok and viola, the blank file looks exactly like the Canvas in FCE. I haven't played with a still with this new setting but I will try it on the little project I'm working on.
As for viewing it, I am looking at it on my Mac flat screen. I went into QuickTime Preferences and checked the box for high quality, thank you. Thanks for reassuring me on the file size.
I also don't know what "D4/D16 Anamorphic" means.
I don't understand the fuzzy type. I'm aware these are 72 ppi files and video is not resolution dependent but rather pixel dependent. Computer monitors display at 72 ppi, televisions are higher. I have yet to complete the process of burning a DVD and playing it back on a TV. Maybe that's where I'll see the type showing up sharper.
At any rate, just dealing with this itty bitty project tells me I have a lot to learn about video, never mind learning about how to use FCE as well.

Automatically open file based on MIME type and file extension

We have an app that is registered to handle custom MIME type and file extension. This works perfectly on IE and FireFox causing them to download the file to a temp folder and then launch our app associated with MIME type and file extension with command line to the downloaded file. On Safari however this does not work. It opens up a download window and shows that it has downloaded the file with no option to open it.

.htaccess and MIME types not working in 3.1

anyone else noticed that when using a .htaccess file to determine certain mime types safari 3 ignores the .htaccess file and handles the file the way the OS would normally?
i'm hosting a bunch of 1080p .mov's and I'd prefer if they would just download when clicked on instead of trying to open in a window where they go out of frame.
i've currently got the addtype set to octetstream, and on safari 2 and firefox they both automatically start to download, but safari 3 tries to open the movie in the browser window.

I think that it is interesting to note that as I peruse the various threads dealing with 3.1 update problems the majority of complaints seem to be coming from iPhone/Mac combos; based, at least, on the posters signiture.
For my part, 64bit vista win machine and 3Gs, the update could not have been soother and the phone works better then it did; no app problems, better wi-fi conectivity, faster loading of apps and files.
I have had, though, considerable problems with Outlook sync, contacts sync and MM sync (enough so that I turned off MM except for iDisk); but most of these are known issues so just need to with it out.
Seems like Apple could have workedd this stuff out before hand, though.

Server and MIME types

I'm having a great deal of trouble getting my java web start working I've set up everything on the site but when I click the link it shows the XML code from my JNLP file. I read that I have to set a MIME type on the server but I have no way of changing anything on the server concerning MIME types. Can I somehow specify something in the HTML so it'll open it up? Thanks, Kyle Chalupa

You are quite correct I have a bad MIME type however I don't have access to modify the MIME type definitions on the server nor if I did I wouldn't know what to modify. Is there a way to do it in JavaScript? Kicking up the reward to 5 duke dollars. Please help.
I don't think there's anything you can specify in the
HTML to make it work. I downloaded your jnlp file and
tried to open it in JWS and got the following error:
An error occurred while launching/running the
application.
Title: Tic Tac Toe Application
Vendor: Kyle Chalupa
Category: Download Error
Bad MIME type returned from server when accessing
resource:
http://www.sunysuffolk.edu/~chalk43/tictactoe/tictactoe
jnlp - text/plain
So that says to me that the mime type has to be set on
the server for it to work at all.

Downloading spreadsheet mime types via weblogic 6.1

          I'm having a problem with a jsp file -- within the weblogic v6.1
          server environment that wasn't occuring when using v4.5.1.
          The jsp page in question is supposed to handle downloading a
          spreadsheet file via a 'post' method from within another
          (calling) jsp page. The code that (used to) do this looks like
          this:
          <%
          System.out.println("Debug -> /GetSpreadSheet.jsp -> begin");
          //response.setContentType("text/plain");
          response.setContentType("application/vnd.msexcel");
          response.setHeader("Content-disposition", "attachment; filename=list.csv");
          // This is the java class object (previously saved as a
          // session variable) that contains the spreadsheet data
          CList cList = (CList)session.getValue("nameSpace.cList");
          String csvOutput = cList.getCSVOutput();
          // This doesn't work either...
          //String csvOutput = "Testing 1-2-3";
          PrintWriter pw = response.getWriter();
          pw.println(csvOutput);
          pw.close();
          %>
          Note: As you can see, I'm not actually opening an existing
          'csv' file via some file I/O code -- but instead taking a 'csv'
          formated String object 'csvOutput' and feeding it directly to
          the PrintWriter println method.
          With the v4.5.1 app server, when the user acknowledged the
          expected 'download file' dialog box and specified the location
          on his PC to download file, the desired results would happen
          (the file is downloaded). With the 6.1 app server, this jsp
          file goes into a loop (based on entries in a debug log file)
          before eventually timing out. The browser (both NS & IE)
          displays an error page and the file download doesn't happen.
          My original web.xml file (in DefaultWebApp/WEB-INF directory) was
          as follows:
          <?xml version="1.0" ?>
          <!DOCTYPE web-app PUBLIC "-//Sun Microsystems, Inc.
          //DTD Web Application 1.2//EN"
          "http://java.sun.com/j2ee/dtds/web-app_2_2.dtd">
          <web-app>
          <welcome-file-list>
          <welcome-file>index.html</welcome-file>
          </welcome-file-list>
          </web-app>
          After reading through some suggestions of some of the WL
          newsgroup postings, I changed it to:
          <?xml version="1.0" ?>
          <!DOCTYPE web-app PUBLIC "-//Sun Microsystems, Inc.
          //DTD Web Application .2//EN"
          "http://java.sun.com/j2ee/dtds/web-app_2_2.dtd">
          <web-app>
          <welcome-file-list>
          <welcome-file>index.html</welcome-file>
          </welcome-file-list>
          <mime-mapping>
               <extension>xls,csv</extension>

               <mime-type>application/vnd.msexcel</mime-type>
          </mime-mapping>
          </web-app>
          This didn't help. There was no change with the problem.
          Is there anyone out there who knows the secret to this mystery?
          Thanks,
               -- WC

Safari and MIME type "application/x-mplayer2"

When trying to listen to web pages conatining mp3 audio files (prior to purchasing them) , Safari comes up with a message saying that MIME type “application/x-mplayer2” is not installed and only downloads the html file and not the mp3 file. When we check on our installed plug-ins in Safari, MIME type “application/x-mplayer2” has been installed.
How do we fix this? We are using Safari Version 2.0.2 (416.12) OSX 10.4.3. It works on one of our older machines running Safari Version 1.3.1 (v312.3.3) OSX 10.3.9

Nevermind. I answered my own question. Seek and you shall find. http://www.apple.com/safari/download/plugins.html I just had to DL the WMV plug in. All better.

Case sensitive file extensions on mime.types?

Hello,
I'm facing a weird problem at customers's site.
There is an iAS 10.1.3.3 installation on a Windows 2000 server. There is an OC4J container called "OC4J_FR" where their application is depoyed.
The trouble we're facing is the following:
on the %ORACLE_HOME%/j2ee/OC4J_FR/config/mime.types we add the following 2 entries:
image/tiff                    tif tiff
application/vnd.ms-excel     xls
So, when we put someFile.tif (or someOther.xls) under the container public directory it is possible for users to access them via the URL
http://servername:port/webContextRoot/someFile.tif
And this works OK.
If we try to rename the above file into something like myFile.TIFF (please note the extension in uppercase) Internet Explorer opens it like text, wiring this "rubbish":
II*Àg ÒgL1ÂÊ$(2ÈdÙ¨¦Í@6j)³P‘<mò°Ú¨³
etc....
While Firefox opens it correctly. I also tried to add on mime.types the following (even if on the Apache website it is told that this is useless...)
image/tiff                    TIF TIFF
But still it doesn't work.
Any hints/patches/workarounds/ideas/anything?
Thanks,
- Paolo

Can't really say what's wrong but I quickly tried it with OHS (Oracle HTTP Server) and it works fine both in Firefox 3.0 and IE 6.0 without making any change (in mime type configuration). I copied two tiff files (sample1.tiff and sample2.TIFF) in $OH/Apache/Apache/htdocs directory and then was successfully able to access both using http://host.domain:ohs_port/sample1.tiff and http://host.domain:ohs_port/sample2.TIFF.
When you say you tried with Apache website, is above what you tried too?
Thanks
