Global MIME type settings in JDS

I've recently started working with JDS on Solaris 10. I want to create global MIME settings so that any user that logs in will have the same file associations. I've gone through all the info from the GNOME website regarding update/changing the MIME database (create Overrides.xml run update-mime-settings). However, I can not get the settings to take effect for all users. Basically, I want to set the file associations as root and have them be the same for all users.

I too need this information, but seeing it's been over a year and no one replied to the thread starter.....

MIME type settings for browser are IGNORED

I have the following problem since Quicktime 7 Preview 2:
Quicktime by default has many mime types associated which I don't want to be played by quicktime in my browser.
For example .mp3
So I deselected everything but Quicktime movies in the mime type associations.
But no matter what I deselect there - Quicktime is stil playing everything in the browser.
It seems that Quicktime conmpleteley ignores the mime type settings in the preferences and plays everything by default!
What do I need to do to fix this?
In versions 7 Preview 1 an lower these settings worked just fine.
And as long as this isn't fixed I won't use Quicktime 7...

The "hijacking" of files types and file extensions has been a part of every piece of software I can remember. Particularly with browsers and media files.
Not all browsers use the same types of plug-in architecture and this may be what you're experiencing.
It's been a long time since I fired up Internet Explorer on my Mac. Many browsers still use its style.
On a Mac (maybe the same on a PC) Internet Explorer uses its own "File Helpers" for MIME types. These can be edited using its "preferences".
Try changing the settings in IE. You'll find them under "helpers" (or something named like that).
Because Microsoft has tried to put its own formats in "front" of viewers these obstacles will now be part of much of your online experience.
User (viewers) do have most of the control. It's a shame that we have to fight just to get what we want in our online experience.

MIME Types

I need to know how to alter MIME type settings in OS X. I would like to use another media player other than QT to play MPEGS off the web because I would like the ability to go full screen. I have tried unchecking the MPEG file types in Quicktitme, in theory removing QT as the default player, but Safari and Firefox both still default to QT when I click on that type of link.
Can someone please tell me where I can make changes to and manually add MIME types?
Thanks!

Hi, Echomancer.
Two suggestions for you:
1. See "Mac OS X 10.4 Help: Changing the application that opens a document."
2. Try the freeware application RCDefaultApp. Safari, unlike many other browsers, doesn't provide a way to assign "helper apps" to specific MIME types.
Good luck!

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?

Safari can't find plug in MIME type "video/x-ms-asf-plugin"

hello. i feel seriously computer illiterate at the moment.
i want to listen to something,
but it tells me this:
The page “radio soleluna jova channel” has content of MIME type “video/x-ms-asf-plugin”, but you don’t have a plug-in for this MIME type. This page may have the plug-in for you to download and install:
http://www.microsoft.com/windows/mediaplayer/download/default.asp"
i went there and installed wmp the lastest version, and some quicktime-wmp related thing for macs, but still no go...what kind of program do i need to run this plug in or whatever?
thanks in advance.

Hi and Welcome to Apple Discussions
That station is streaming their audio in a Microsoft sound format.
The only way you'll be able to play Windows Media content in native mode on your Intel machine is using the free plug-in Flip4Mac plug-in. This plug-in automatically converts the windows content to a Quicktime format, which will play within Mac browsers.
After downloading the plugin, double click on the download file to install the plug-in. There's really nothing else you need to do with the plug-in, as the default settings are sufficient for your needs.
Next step is deciding where you can play Radio Soleluna. I tried it on Safari 4, but the content does not play. More than likely, this is due to how the site is coded. A good browser alternative that does play the content is Firefox 2.0.0.5. Once installed, you can import your existing Safari bookmarks to Firefox. This way you can access content on either browser.
Before dealing with the Bookmarks (I'll provide guidance), download Flip4Mac, and if necessary, Firefox.

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 plugin

I am a new apple user and want to use my computer to listen to the radio. I am getting a message that says I need a mime type plugin. What does this mean and I do have to download microsoft media player?

Thanks for the link.
I also use FireFox as my main browser & had no problems listening to the live streaming radio. However, I have both Flip4Mac & VLC media player installed.
Make sure you have the latest version of QuickTime installed.
Check your QuickTime browser MIME settings to make sure your streaming settings are enabled.
Quicktime>Quicktime Player Preferences>Advanced
Click on the MIME Settings button.
In the next window that opens up make sure that Streaming-Streaming movies is enabled (checked).
While you’re at it make sure all the boxes are enabled especially the Audio box.
Click the OK button.
Repair permissions & restart for good measure. Hopefully, this should do the trick for ya!

New keepassx (0.4.0-1) global auto-type key not working with Win-key?

After system upgrade in new version of keepassx (0.4.0-1) stop working global auto-type key set previously to Win+K stop working. I tried to set it once more (menu Edit->Settings->Advanced) but combinations with Win key are not recognised anymore. I am just curious if anybody have same problem. Anyway, I happily downgraded back to keepassx 0.3.4-1 .

I found it at http://archlinux.alouche.net, got there from Downgrade packages. Direct links: i686, amd64.

Java.lang.InstantiatiCould not read mime-mappings config file: ./mime.types

I am about to had enough of this moronic container call OC4J that's compatible to to itself.
I did a
1. clean unzip and installation.
2. setup admin account.
3. config the autodeploy in server.xml (Who in their right phreakin mind design a container with no hot deploy nowaday).
4. configure the data source.
5. test data source using a webapp with one page jsp do a JSF jdbc connection.
When try and deploy the error-free webapp (tested in tomcat) using both frontend and autodeploy,a cryptic error occur: could not read mime.types.
I have never see this error before in my life. its in oracle.oc4j.admin.internal.ApplicationDeployer.addApplication
This error happened after I configure my webapp to do phreakin orion-application.xml disable toplink, orion-webapp xml prefer local class file. If I don't get this resolve within couple days, I'll put my career on the line with full force and request we do not use OC4J anywhere in this group.
A M$FT .NET project looks very promising and efficient compare this deployment hell they call OC4J

Thank you Steve for your help. I really do appreciate ppl taking the time to answer questions from n00b like me.
I tried and disable global.libraries and global.tag.libraries when deploy, and at one point the login page (its Spring 1.2.8 + hibernate 3.1.3 + Myface 1.1.4 + acegi 1.0.1 ) came out, but cannot login and without exceptions, so I was guessing acegi poblem. But the spring and hibernate is working, I can see the conn and other activities. And after a couple tries, cannot even get the login page display now in MyFace, with exceptions:
include(java.lang.String) in javax.servlet.jsp.PageContext cannot be applied to (java.lang.String,boolean)
And then after some googling found out there will be code change for this webapp as well.
- change webapp.listener for double instantiation in OC4J (Code Change)
- create new class OrionSessionListener implements HttpSessionListener for session invalidation (Code Change) NEW JAVA CLASS
- acegi j_security_check URL reference change (Code Change, but minor)
I think the container has great performance, but I just wish they can look more to the compatabilities/common practices issues

Unable to launch application from my machine:Bad MIME Type

Hi,
The following error message was printed when I tried to access the SwingSet2 demo from the Java Web Start site.
An error occurred while launching/running the application.
Title: SwingSet2
Vendor: Sun Microsystems, Inc.
Category: Download Error
Bad MIME type returned from server when accessing resource: http://java.sun.com/products/javawebstart/apps/SwingSet2.jnlp - text/html
Can you please suggest what is to be done to rectufy this problem?
Regards,
Satish

Bad MIME type returned from server when accessing
resource:
http://java.sun.com/products/javawebstart/apps/SwingSet
.jnlp - text/htmlit should return application/x-java-jnlp-file.
My guess is that you use proxy which messes up headers.
Otherwise try to reinstall Web Start, then enable the console and log output in Web Start's advanced preferences to get more clues what's going on.

How to change default application associated with some mime types?

When we install some new program, for example GIMP, I assume the newly installed program is added to some mime type database, and the /usr/share/applications/mimeinfo.cache file is automatically generated.
Using my example, GIMP will be the default application for all its registered mime types, even application/pdf. I surely don't want this to happen, and I surely don't want to create all kinds of files that GIMP registered and right click on them and choose Properties and then change it in the Open with... tab. I want to systematically de-prioritize GIMP so that it will not override my previously assigned default applications.
I wrote a script to modify the mimeinfo.cache file, and it seems to work great. However, after a reboot or upgrade or something I didn't notice, the default application of application/pdf is reconfigured to GIMP. I think the cache suffix of the file indicates that it is just a cache and may be changed by system unnoticed. So I am looking for a new way to change the default applications.
As far as I know or guess from the phenomena, there should be some system utility that generates the mimeinfo.cache file, it seems to parse all the *.desktop files under /usr/share/applications and register them to certain mime types accordingly. The sequence of the *.desktop files get parsed seems to be related to the time the application is installed, and the newly installed applications seems to be parsed later and inserted in the front of the application list or be parsed earlier and appended to the application list. Is there some place I can change the sequence of the parsing? Or is there some place I can change the behavior of the system utility?
I know that I can populate my ~/.local/share/applications/mimeapps.list to override the system wide defaults, however, I want a more elegant way to this.
Any opinion on this is welcomed.

Ah, right. Don't know what DE you are on, but in Gnome: right-click a (e.g. pdf) file -> Preferences -> Open with.
All Applications listed there will be available from the right click menu, the marked one will be used on double-click.
errgrh...
I surely don't want to create all kinds of files that GIMP registered and right click on them and choose Properties and then change it in the Open with... tab. I want to systematically de-prioritize GIMP so that it will not override my previously assigned default applications.
I guess what I am trying to propose is this: "de-prioritize" GIMP in its .dekstop file for the types you dont want it to be associated with, and manually add it back in through "Open With" for the file types you want it to be an option. Not sure if this is solving anything for you though

File/Open Dialog Box / Setting MIME type

In my application, I am calling a web service that returns text that I need to download into an EDI application. I am simply looking to have an open/file dialog box open when the text is returned. I was using the following code in a PL/SQL process:
begin
-- Set the MIME type
owa_util.mime_header( 'application/octet', FALSE );
-- Set the name of the file
htp.p('Content-Disposition: attachment; filename="EDIOuput.edi"');
-- Close the HTTP Header
owa_util.http_header_close;
end;
The problem is the HTML code that comes along with the text that is returned. Is there a way to simple call the procedure on a page that only containes the raw data?
Thank you.

HTML doesn't provide you the possibility to select multiple files or select folders at a single browse. Thus JSF can't do any much for you. Best what you can do is to write a signed applet or web start application which does the task. The Mojarra Scales component library has a ready-to-use component which embeds an applet which does that task. Check [https://scales.dev.java.net/multiFileUpload.html].

How To Get FileType and MIME Type from a File

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.

File file = new File(filePath);Why do you do all above?
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.That's because there's no way to get MIME type of all files on all filesystems.

How to restrict uploading files by mime type?

Hi,
I have been searching the forum (and Google) looking for tips on how to ensure users can only upload files of specific formats (Word, PDF, etc) for specific document types as defined within the application (e.g. Curriculum Vitae (Word), Copy of Transcripts (PDF)).
While I have used this research to start work on a server-side solution, I would like to know if there is an apex-friendly way to "validate" a file-browse item based on mime-type.
Has anyone else had to address this?
Ted

Hi,
I would like to know if there is an apex-friendly way to "validate" a file-browse item based on mime-typeHow about, you create a check constraint on your MIMETYPE column. something similar to this:
alter table "MY_TABLE" add constraint
"MY_TABLE_CON" check ( "MIMETYPE" = 'application/pdf' or "MIMETYPE" = ......)Or you can use this plugin, provided using browsers supporting HTML 5:

For friendly,
Please check error handling :
