Open File from Filesystem with OutputLink

I have implemented an UploadForm with JSF. With this form a File is uploaded to my filesystem and some data (link to filename, filename itself and so on) are written to the Database.
No I display these data from the database in a datatable and I want to implement a link, that the user can open the file from the filesystem. I have tried a outputlink with something like that:
<h:outputLink value="file:C:\Entwicklung\IDE\eclipse\readme.txt" target="_blank">
               <f:verbatim>
                    Test
               </f:verbatim>
</h:outputLink>
I'm not sure if the file: Command is the right...
The problem is, that nothing happens. When I try to save the file, pressing the right button and choose "Save as..." the file is correctly saved.
How can I implement a link to open a file from the filesystem?
Regards,
Andy

No the file won't be a html file..
I will be some kind of pdf or doc?
So how to launch them? Do I need an Outputstream?
Has anyone experiences with that?Any file could go as an href value.
Issue is not file type, but a proper URI that the server could resolve.

Open file from table with double click

Hi all,
I use adf faces and JDEV 11.
I want to open a file by double clicking on row in a table. (file is stored in the database).
I first tried it with a button to open the file, with this code:
       System.out.println("Double click!");
       BindingContainer bindings = this.getBindings();
        DCIteratorBinding iter = (DCIteratorBinding)bindings.get("XxahelpBezoekRapDocView1Iterator");
        Row row = iter.getCurrentRow();
        FacesContext fc = FacesContext.getCurrentInstance();
        HttpServletResponse response = (HttpServletResponse)fc.getExternalContext().getResponse();
        response.setHeader("Content-Disposition","attachment; filename=\""+row.getAttribute("Filename").toString()+"\"");
        response.setHeader("cache-control", "no-cache");
        try {
            InputStream in;
            in = ((BlobDomain)row.getAttribute("Bijlage")).getInputStream();
            ServletOutputStream out = response.getOutputStream();
            writeInputStreamToOutputStream(in, out);
            fc.responseComplete();
        } catch (IOException e) {
            e.printStackTrace();
        } This is working fine.
Now I wan't to open the file with double clicking on a row.
For opening the file I use the same code in the backing bean and this code on the page:
      <f:facet name="metaContainer">
    <af:group>
        <trh:script>
           goEditRow = function(event) {
                AdfCustomEvent.queue( event.getSource(), "doubleClickOnRow", {}, false);
        </trh:script>
    </af:group>
    </f:facet>And a clientListener and serverListener on the table:
<af:clientListener method="goEditRow" type="dblClick"/>
<af:serverListener type="doubleClickOnRow" method="#{backingBeanScope.backing_pages_EditTicket.doubleClick}"/>The only thing that happens when I double click is that I see "Double click!" in the console. But I can't save the file :S
What is the problem?
Thanks in advance.

Hi
What we do is to pick a table column for downloading the file.
We change the component in the column to the an af:commandLink and add an
af:fileDownLoadActionListener to the command link.
The user clicks on the link to download (open) the file.
Its not exactly the same as what you requested (double
click on the row) but it might be another solution.

Paul

Opening files from WebUI

Is it possible to forse IE to open files from IFS with asociated program out of IE window?
If I choose to open .xls file it should open in Excel and not inside IE window.

I looked in IE 5.5 & IE 5.0(on Win2000) and there is no 'Launch browser windows in a separate process' option nor any other similar option under 'Internet options'.
Any ideas why?
in IE 5.0 (Win 98) I found that option but it doesn't work - files are still opening in IE window.

Problem with 9.3 Reader when opening files from internet

I keep receiving the message 'There is a problem with Adobe/Acrobat Reader. Please exit Adobe Acrobat/Reader and try again' when trying to open come files on the internet. I am able to open files from my hard drive and some files from the internet. I have uninstalled and re-installed Reader, but get same result. Any ideas?

As I posted on Feb. 19 this is what works for me. OS is Windows 7 64-bit, AdoveReader 9.3.1., IE8.
Open Adobe Reader,
            go to edit menu,
            under Preferences
            go to Internet, uncheck "Display pdf in browser"
The pdf files then open, but not in the browser
or if you have Google tool bar installed:
On the Google tool bar
                        click on the options icon (a wrench)
                        go to Tools
                        scroll down to the bottom
                        uncheck Translate
Or uninstall the Google tool bar.
Pdf files open without a problem in Firefox.
All of these solutions are easy.
Good luck,

PSCS6 no longer recognizes my CR2 files and will not open. Using Canon 5DMark III with updated Camera Raw . It has worked before but now won't open files from this camera.

I have been able to open files from this camera before but still checked for latest Camera Raw download. Still won't open files from this camera. Opens files from my 60D just fine. I downloaded the latest and it has worked before. What the heck is going on?

Glad to be of help. But I'm curious (not critical of what you are doing) to know why so many people like to use Nikon Transfer to transfer their files to the computer. It is still necessary to import them into Lightroom. And, from my perspective, it seems simpler and maybe even a little quicker to use the Lightroom import dialog. I have Nikon cameras, and have never even installed the Nikon Transfer utility. What is so unique about it?

How can I read pdf files from LabVIEW with different versions of Acrobat reader?

How can I read pdf files from LabVIEW with different versions of Acrobat reader?
I have made a LabVIEW program where I have possibility to read a PDF document. When I made this LabVIEW program it was Acrobat Reader 5.0.5 that was installed on the PC. Lather when the Acrobat Reader was upgraded to version 6.0, there was an error when VI tries to launch the LabVIEW program. And Later again when we upgraded to Acrobat Reader 7.0.5 I must again do some changes and rebuild the EXE files again
It isn't so very big job to do the changes in one single LabVIEW program, but we have built a lot of LabVIEW programs so this take time to due changes every time vi update Acrobat Reader. (We have build EXE files.)
The job is to right click the ActiveX container and Click "Insert ActiveX Object", then I can brows the computer for the new version of acrobat Reader. After this I must rebuild all the "methods" in the Activex call to make the VI executable again.
Is there a way to build LabVIEW program so I don't have to do this job every time we update Acrobat Reader?
This LabVIEW program is written in LabVIEW 6.1, but I se the problem is the same in LabVIEW 8.2.

hi there
try the vi

it uses DDE or the command line to run an external application (e.g. Adobe Acrobat)

You were probably using the Release Candidate version of camera raw 8.7, which one gets from Adobe Labs.

Can't open files from Bridge in CS6

All was good with CS6 until today - it will not open files from Bridge. Jpg and RAW, neither will open, it's driving me bananas! Any suggestions?
Edit: Problem solved. I had overlooked an old version of PS 7.0 was still in my program files and CS6 Bridge had picked it up as default editor. Deleted PS 7.0 and everything is back to normal. Phew!

Lots of questions here, will see what I can add.
For the file problem go to preferences/file type associations. You should have the option selected CS6 for the extenstion as the default. Might try the radio button on the bottom first to set them to default settings.
If the 1.77g file you are refering to is the one you downloaded and used for installation you can delete it. It is a wise choice to save it to a DVD first so in case you need it in the future you will have it. Also save the serial number in safe place. Acutally safe is not the right word, need to save in place where you can find it if you need it next year. HD can fail.
There are still thrid party plug-ins that do not work in 64 bit mode, hence the 32 bit version. Also there is no 64 bit TWAIN so some still like to use that for scanning.
Some users experience file association and other problems with an uninstall of past versions. So it is safest to leave them be.
If you want to clean up a little resist the urge to move any Adobe programs once is is installed. Can really foul it up.

Windows client - error opening file from OS X Server

We discovered, that some files cannot be read from windows applications via the server - Xserve 10.4.8 Server.
When we try to open files from applications (open dialog, or double click ) via the server, the apps stop reading with errors. These errors occour not with all files!
A copy of these files to the local Win-machines of course can be read.
But, using a normal Win XP machine as a "server" will work fine.
We use the latest Xserve and Software and Win XP-64 Clients with a 1000BaseT Network.
Is there a samba issue, or can we modify some settings?
This is really frustrating, because this was the reason why we bought the Xsever.
Can anyone help me?
Regards Markus

The only thing I can offer you is a "me too".
I have the same issue, but it only appears in some applications. My guess is that the method the application uses to open files makes the problem appear; other applications the users are using do not have this issue.

DW CS3 no longer opens files from SourceSafe

Dreamweaver CS3 no longer opens files from Visual SourcesSafe
2005 when you right-click and choose to View with DW, even if DW is
the registered application.
DW receives the focus, but nothing happens.
This used to function with DW 8. I have tried it on two
machines, both of which were fresh installs, so could not be
conflicting with DW 8 in anyway.
Is this a known bug?
Matt

It seems this is a known issue with Dreamweaver. I was able to access the files just fine by deselecting "display external links" in the view menu. Strange that I did not have to do this before.

Word, PowerPoint and Excel Crash when opening Files from Sharepoint Site.

Hello,
I am in the process of rolling out office 2013 company wide. I have started with a batch of test users and a few including myself are reporting various office apps crashing with opening files from our SharePoint site. Although at times it will crash outside
of the site.
I have tired running each app in various modes (Safe-mode, Compatibility mode ect) but the same results keep happening. Although it does not happen all the time on other users machines its more frequent. If i download the file and open it locally this does
not appear to happen.
We are all running Office 2013 SP1 32bit on Windows 7 Machines.
One Common issue they everybody seems to have always points to "Faulting module path: C:\Windows\system32\VBScript.dll". I have done some digging but have not encountered any solution that points to this file. We constantly stay current on the
latest updates from MS.
Any suggestions would be very helpful.

Bump - Wondering if anybody has seen this before?

How can I check the open-mode of an opened file from the file refNum?

How can I check the open-mode of an opened file from the file refNum?
Especially whether a file is opened as read-only or write-only? I haven't found any VI in the panel with file VIs.
Thanks for any hints!

Check this post. Probably you can use a kernel.dll call.

Photoshop CS3 lauches but does not open files from Lightroom 2.7

These programs have been on my computer since the dawn of time and have always worked. Now all of a sudden I can't open files from LR into PS. PS launches, but the files don't open. I get that message Photoshop could not be lauched, which is ironic since the program is now open.
I haven't done anything to the programs so it makes no sense. IN the past I have had issues with PS and the tech had me create a new login on my computer and it fixed things. Tried that. No help.
Does anyone ahve any suggestions. I have repaired both programs to no avail.
Thanks for you help.

Something has gone wrong with how Lightroom finds and communicates with Photoshop.
That could be a registry string, or some preference within Lightroom.
The Lightroom forum is more likely to be able to help you solve this.

Open files from terminal (gnome-open doesn't work properly)

How can I open files from terminal? On Ubuntu, I used xdg-open. On Arch, I have gnome-open, but I can only open directories with that, not files directly. This sucks bucause I like navigating through my files using the terminal instead of a file manager, which doesn't make that much sense if files can't be opened directly.

Obviously you probably have different app preferences than me. And you'll probably have to sed away the "-usercreated" strings because I am anal about having my own desktop file for everything.
