Mime type issues: x-directory/normal vs. inode/directory

Sorry for the long post. If you have no time, just read the third paragraph, starting with "Of course..."
I am using KDE and I have a problem with the mime types for directories. As Gnome, too, KDE manages mime types itself to offer easy customizability by means of GUIs. Obviously, KDE programs natively adhere to these settings. When a non-KDE application wants to open a file of a certain mime type, it should call "xdg-open" which checks for the desktop environment and the calls the "kde-open" script to use KDE's own mime type hierarchy. However, when a program does not call "xdg-open", the (by now ancient) /usr/share/applications/mimeinfo.cache is read. This file is created by /usr/bin/update-desktop-database, which is executed in many PKGBUILDs (well, actually the .install files) to update mime information after installation.
The problem I am running into is that Zotero, a Firefox extension for bibliography management, does not open Dolphin, KDE's file manager, but EasyTag, a music file ID tag editor whenever a folder is supposed to be opened. A quick look at /usr/share/applications/mimeinfo.cache shows that Dolphin is registered as an application for the mime type "inode/directory", but not for "x-directory/normal", for which EasyTag is registered. Simply adding Dolphin as the first app in the array for "x-directory/normal" solves the problem, but only until the next update of a program calling /usr/bin/update-desktop-database. I thus wrote an alias command to call a selfmade script which uses sed to rectify this after each call of update-desktop-database.
Of course, this is not a nice solution. Thus my question (Google didn't help much): What is the standard mime type for directories? AFAICT, it should be "inode/directory", but what, then, does "x-directory/normal" do and why is it used? What should the solution be? Should Dolphin register the additional mime type?
I suspect an error on behalf of the KDE devs as I just realized that a few other KDE programs don't claim certain mime types, either: Okular does not claim "application/pdf". The GIMP, however, does, even though it cannot handle this mime type.
Thanks for your patience.

An even better workaround. Nice!

MIME type issue in version 4.1/4.2 Compatibility Mode

Problem: when displaying a PDF file, it displays OK as PDF if APEX 'Compatability Mode' = 'Pre 4.1', but displays as HTML when in either '4.1' or '4.2' mode.
Apex: 4.2.2.00.11
DB: 11gr2
Web server: Apache on Linux
More detailed description... this seems to be a MIME type issue related to APEX (or maybe DB) versioning. The following code works as expected when run in 'Pre 4.1' mode - ie. it displays an appropriate PDF document in the appropriate Acrobat/other plugin in several browsers (Firefox/Opera/Chrome/IE). But just by changing 'Compatability Mode' to '4.2' (or even '4.1'), it then downloads the file but displays it as a bunch of random characters, and the web page header MIME type is 'text/HTML'.
Note: this also happens with other file types such as xls/doc/etc, but I expect fixing PDF should also fix these.
I'm at a bit of a loss as to where this is happening, it seems there is a difference in the 'Compatibility Modes' between either the creating of the HTML header using 'OWA_UTIL.mime_header' or the component path it traverses before reaching apache.
The only other thing I could think of is that we do a bit of redirection to display the PDF, though this seems like it might be a red herring. Basically we use page 560 as a container, and then display the PDF with page 561 within a frame embeded within page 560. So, on the page 560, which is the one we reference throughout the application, we have a region with a source of '<iframe src=?p=&APP_ID.:561:&SESSION.height="500" width="700"&gt</iframe&gt</pre>'. Then on page 561, in a 'On Load - Before Header' process, we make the call to the code 'DOWNLOAD_APPLICANT_PDF' (below).
Note: I did try calling 'apex_application.stop_apex_engine' after 'DOWNLOAD_APPLICANT_PDF', as suggested in a couple threads, but it didn't fix the problem, and caused a couple low-level system errors.
Code:
<pre>
CREATE OR REPLACE PROCEDURE DOWNLOAD_APPLICANT_PDF ( p_doc_id IN   NUMBER
   AS
      v_length      NUMBER;
      lob_loc       BLOB;
      l_display_inline   CHAR := '1';
   BEGIN
      SELECT pdf_data, DBMS_LOB.getlength (pdf_data)
        INTO lob_loc, v_length
        FROM pdf_dest
       WHERE pdf_dest_id = p_doc_id;
      OWA_UTIL.mime_header ('application/pdf', FALSE);
      HTP.p ('Content-length: ' || v_length);
      HTP.p ('Content-Disposition:inline;filename="mydoc.pdf"');
      OWA_UTIL.http_header_close;
      WPG_DOCLOAD.download_file (lob_loc);
END;
</pre>

MIME-type issue???

I have installed WLS 6.1 and have placed my index.html file in the
applications/DefaultWebApp_myserver. Everything works fine. For
organizational purposes, I want to place all of my documentation in
DefaultWebApp_myserver/doc. When I display a MS Word document (IE 6),
within the /doc subfolder, the document displays as ascii text. However, if
I place the document in the DefaultWebApp_myserver folder, it displays
correctly as a Word document.
Additionally, Excel (xls) documents display as ascii/text regardless of
their location.
Any ideas or suggestions would be greatly appreciated.
Thanks

Kumar,
I've tried all combinations of the following with no luck:
Extensions:
<extension>.doc</extension>
<extension>doc</extension>
<extension>DOC</extension>
MIME-types:
<mime-type>application/winword</mime-type>
<mime-type>application/msword</mime-type>
<mime-type>application/ms-word</mime-type>
I restarted the web server after clicking the "persist" button from the web
descriptor page. My directory structure is as follows:
Root location: .../mydomain/applications/DefaultWebApp_myserver
Doc location: .../mydomain/applications/DefaultWebApp_myserver/doc
Location of web.xml:
.../mydomain/applications/DefaultWebApp_myserver/WEB-INF
Once again, viewing a Word document, located in the root location, works
fine. Viewing a Word document in the /doc subdirectory displays as ascii
text.
Thanks again for your help.

Mime Type issue with .docx Files in Apex 4.0

We are having issues with windows 2007 .docx documents that are when they are viewed on windows 2007 machines with ie8. If I look in the storage table the mime type is not set correctly. It is being set as application/octet-stream. When we download the file one windows 7/IE8 either the browser thinks it is a zip file or it does not recognize it.
If I go into the back end and update the table with the correct mime type application/vnd.openxmlformats-officedocument.wordprocessingml.document it works fine.
We have tried to update mime types on the apache server but this does not help.
Apex seems to be deciding what mime type to populate the table with.
It seems like I need to update apex somehow to recognize that a .docx extension should be stored as type mime type application/vnd.openxmlformats-officedocument.wordprocessingml.document.
Does anyone know how I would do this?

Ristretto or maybe generic mime.types issue: case of file extension?

Good day.
Ristretto (the XFCE image viewer) wouldn't recognize the .TIF files I copied over from a Windows partition until I renamed them to .tif. Lowercase .tiff and .tif are indeed the only two file extensions that are mentioned for image/tiff in /etc/mime.types but I thought this was somewhat unexpected (and unwanted).
Is it a per-app decision whether or not to do case-sensitive extension compares? Is it a problem? And if so, in mime.types or in ristretto?

Rene

CLM Mail MIME Type Issue

Users are entering special characters in the instructions to the signatory, and when the string is picked up into the custom email, the system is mis-translating the characters in the CLM.We suspect on the custom java mail util not setting up the MIME Type.
Any help would advise on this

In custom email, you manually set the content type. Here is an example:
msg.setContent(txt,"text/html");
where txt is the formatted string.
and msg is of type MimeMessage.
Incase you are using the method "setText", change it as shown above and it should work fine

Servlet application MIME type browser window issue

Hi,
I am writing a servlet that launches an application on a citrix server and as such the MIME type is as below:
response.setContentType("application/x-ica");
The user is supposed to click an internet explorer link on their desktop and the application will open, however currently a browser window opens and remains blank while the application launches and does not close until done so manually. I have seen examples where users can click a link and the browser window closes itself straight away, and the application continues to launch.
Can anyone advise how to correct this problem?
Thanks.

I've found out what the problem was, wasn't related to the servlet itself it was a client side custom component making multiple requests, which the app replied to with different content types.
Thanks.

.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.

Safari cannot find the Internet plug-in (MIME type...x-shockwave-flash)

Well, YouTube and other flash sites worked fine just until today. So I get this message :
+The page “YouTube - Meet Single File” has content of MIME type “application/x-shockwave-flash”. Because you don’t have a plug-in installed for this MIME type, this content can’t be displayed.+
I've already tried Disk Repair to repair the permissions, installed, re-installed Flash Player and Shockwave Player and nothing yet. System preferences with QuickTime Advanced Panel to enable flash and the other miscelaneous one I unchecked, the normal procedure, I guess. Also checked the libraries to see if I didn't have the plugin in two libraries, but i'm not sure about the library/plugin issue.
Any help is much appreciated.
Best Regards,
Kinetick

I actually don't get any error message at all. The Q is greyed out and a large ? in center of it and nothing works in Safari. I get the same non-message wherever I go that has QT. I have tried some of the fixes that have worked for other people but nothing works so far. I tossed the webplugin into the trash and restarted Safari. I repaired permissions. I looked at the plug-ins list in help but that was only confusing since I don't have a clue what any of those control. Getting frustrated and have spent a couple of hours trying to fix this.

Changed mime type associations !

I recently installed gimp, and now when I open any downloaded pdf files, they are opened in gimp.
Files previously downloaded and saved are however opened in 'evince'. I use open-box, Chromium, Rox-filer and evince, as DE, browser, file-manager and document viewer respectively.
I searched the wiki and found two entries that I thought might help, Default Applications and Custom file associations, I've tried both user specific options in these pages, here are the files I created:-
[bance@archbox ~]$ cat .local/share/applications/defaults.list
[Default Applications]
pdf=evince.desktop
[bance@archbox ~]$ cat .local/share/applications/evince.desktop
[Desktop Entry]
Name=Evince
Exec=/usr/bin/evince
MimeType=application/x-evince
Icon=evince
Terminal=false
Type=Application
Categories=DocumentViewer
Comment=
Neither of these has worked, do the files look ok? Have I made a mistake somewhere?
OK whilst writing this post, I noticed that I have a file /usr/share/applications/mimeinfo.cache, It contains a list of mime type associations, would editing this work?
TIA Steve

you need!! the inode/directory setting in the mimetype list. That's what chromium reads to autopen your file manager.
Make sure it matches the .desktop file appropriate for your file manager. In the case of spacefm, it is not spacefm.desktop as you might expect, it is spacefm-folder-handler.desktop.
Check your .desktop files for your fm.
If you're still having trouble, you might want to post your mimeapps.list
I noticed in post1 you were using defaults.list instead. Reading the wiki is not super clear on this, but since I downloaded the pkg 'mimeo' I used mimeapps.list instead.
I assume you read the file extension portion of the chromium part of the wiki:
https://wiki.archlinux.org/index.php/Ch … sociations

So switch

How can I use one Add-on prior to another for specific MIME-types?

I'm using Shockwave Flash plugin to watch some videos on YouTube, StreamCloud, etc. It also handles .mkv and .mp4 files/streams. After installing VLC Web plugin to handle MIME-types like mp3/4, mkv additionally and prior to the Flash plugin, Firefox keeps using Flash to handle those types insted. I cannot find options to set the desired priorities. Only disabling the Flash plugin solves my problem, but also keeps me from watching Flash contents, which Is not acceptable.
Did I miss something or is this Firefox's fault?

If you type or paste '''about:plugins''' in the address bar and press Enter, you can see which plugins are associated which various content types.
I do not know how to prioritize one over the other for the same content type if the plugin settings (plugins often have an interface outside of Firefox to adjust their settings) do not allow that.
As for MP4, I don't think Flash normally would be selected. I suspect the website is specifying a Flash media player and streaming the MP4 through that. If you want to hide the Flash plugin from a particular website, you can use the Permissions tab of the Page Info dialog.
Click the padlock or globe icon in the address bar, then More Information, then Permissions. The top section of the Permissions panel should be "Activate Plugins". Here you can select Block for Flash for the current site. After reloading the page, does the media play using a different plugin?
