Java Forum / General / August 2005JAWS and Netscape/Firefox
Netscape is built on Firefox and they seem to have a common omission. There is no way to set up an association, e.g. for JAWS to send JNLP files to javaws.exe. They have plugins, which are more elaborate, but so simple associations, at least not that I could fathom. Has someone written a minimalist plugin to allow JAWS to work? Or is there some simple way to add the association? What is more they appear to ignore the association set up in Windows.  SignatureBush crime family lost/embezzled $3 trillion from Pentagon.

Got an URL? I just tested using Mozilla 1.7.2 and IE 6.0028 on <http://www.physci.org/jnlp/PhySci.jnlp> and they display the *same* behaviour of .. displaing my JNLP in the browser, because I have thus far failed to set up a Mime-Type for JNLP on the server. [ And that is the way to approach this problem, as I understand. ] Don't you have a mime-type *checker* on your site? SignatureAndrew Thompson physci.org 1point1c.org javasaver.com lensescapes.com athompson.info Where No Fan Has Gone Before >Got an URL? I discovered IE, Firefox and Netscape all work with a web based URL, presumably because it gets the extra hint of the mime-type from the server. IE does nothing with a local hard disk reference. It just displays a blank screen with no message. Firefox and Netscape display it as colourised XML. This all seems quite bizarre since the Windows registry has a huge database of mime types and extensions. There is no excuse for any of this. if you want a JNLP file to play with see http://mindprod.com/webstarts/setclock.jnlp SignatureBush crime family lost/embezzled $3 trillion from Pentagon.

The fault lies in the OS/browser. They, between them, should be supplying MIME types for reads from the local file system, effectively simulating a tiny HTTP server.

Both from html file and using cmd /c start file://c:/cygwin/tmp/draw.jnlp. Actually I had expected that it will open them in the browser -- I remember some lengthy discussion in FireFox forums about why not to obey Windows associations. Maybe it is different for local files; even for PhySci.jnlp it asks whether I want to download and save or open it. Running FF 1.0.6 on Windows XPSP2. >It is still opened with javaws That is not what it is doing on my machine. Did you do an experiment or are you arguing from theoretical understanding? With the Windows association set, I can launch from the command line with setclock.jnlp But that still does not help Firefox, Netscape and IE launch a local file. Mozilla is ok, as is Opera, if you set up the association. Sorry I often confuse Mozilla and Firefox. One source of the problem is when you set up the Windows association, Windows is not interested in being told the MIME type. Browsers want the MIME type for confirmation of the association. It is one thing to associate an extension on your machine with a program, and quite another to associate any file on the net's extension with one of your programs.

I suspect the argument is that a lot of users don't know what files are on their system. With Windows Explorer hiding the (lat) file extension it easy to fool a user. >I did try it out. Yesterday and again today. Same results. FireFox asks >me if I want to it Open with JNLPFile (default) or Save it to disk. Are you doing local or web? With me it works fine on the web but not locally. I have Firefox 1.0.6 and Win2K. If you get different results, perhaps the OS is behaving differently. That might explain why this slipped through.

The only way I know of to set up association in FireFox is as follows: when FF asks me whether to open the file or download it, if I tick on the check-box "Do this automatically for files like this from now on" then it creates an association, which I can change or delete in Tools/Options. But this just affects the "automatically" part. Without the association (before setting it up and after deleting it) it asks me what I want to do with it. Always offering JNLPFile default.
