There may be some Java RPC stuff that will do this for you, if you have Java available on the server. If your server is Apache based and allows "Index" (or the equivilent for another server technology), then you could parse the HTML output from a CGI get of the requisite directory. Otherwise, you'll need a server-side process to accept a file name request, perform the file lookup and return the results to your client. Just like Javascript, there's nothing inherent in GWT that performs server side directory traversal. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.

Re: Open a local file with GWT
HI,
i am new to GWT, I have similar query. I want to open a file which is
place somewhere in server file system (i.e. a directory on server
contains some directory and files in it). I have to represent it in
tree structure and display the file on click of leaf Node.
I am paused at opening a file on click event. I want to open it in a
widget ( every time a new leaf node click on tree a file would be
opened opened in same window/widget replacing the old one).
could any one tell me what approach i should follow?
any link or suggestions are appreciated.
thanks in advance.

Re: Open a local file with GWT
I tried adding a button when the callback success and on click event
of that button, call to window.open(path,"_blank",""). this didn't
work, I think that the thing is that the browser doesn't know how to
open that path. The thing I don't understand is why if I open a new
tab on firefox or I Explorer or Chrome wirks without a problem.
Maybe another solution is not to call a rpc to download the file and
instead of that make something like an old servlet that make a call to
download browser. I've trying this thing works since a lot of time and
I still didn't find a solution.
I hope someone could help me with this,
Thanks,
Federico

Re: Open a local file with GWT
It's actually the same thing - don't you think? If you can do smth.
like Window.open("file:///C:\mycreditcard-number.txt") then you also
can go through it though you have full access to popup's Window and
Document objects. But may be i'm misunderstanding smth. here
completely.

Re: Open a local file with GWT
Hi,
I am facing some king of this problem too. What I want to show the preview
of a image which is reside in the local file system of the remote server.
The path of this image is residing in the database like c:\images\sunset.png
How I will show the preview on the GWT panel. If the PipedReader can help
in this this will be great as I do not know about piped reader.

Re: Open a local file with GWT
I don't use an Anchor because I want to open a new windows when the
user hits click on the view document button that I have on the
application. If I use a Anchor, the user must click on my button when
the callback returns, the Anchor will appear and then the user must
click on Anchor to open the document. I try to save this as an
emergency solution.
Thanks,
Federico

Re: Open a local file with GWT
1) That's the local copy on the remote server, right?
2) You could always be sneaky :D. I wonder if a Button.click() would bypass
the blocker - my guess being now as that would be a flaw in the
popup-blocker. One way though would be to do something like in the async
callback, display some kind of clickable message on the screen informing the
user it's ready - they hit ok, you display the doc, bypassing the
adblocker. And you should know, at least with IE & FF, whether or not it's
a popup-blocker issue as the information bar should appear.
3). I think he meant can you actually hit the file by entering the address
in the browser (not if the string looked OK).
4) Like he said, it's not the issue - just cleaner programming style.

Re: Open a local file with GWT
Hi sorry, here is the thing, inside my application an user could
upload documents. Then in some other time if he wants to see any of
this documents he select it from a table and click on a view button on
the selected row. There the AsyncCallback that I've wrote is called,
this makes a local copy of the file in the machine and returns the
path where this local copy was saved.
So now that i wrote some context, I will try to give more information:
1) pdfLink is the path were that local copy of the document is saved.
2) Yes but the thing is that I can't do it outside the callback
because I must be sure that the file is already created and also the
callback is what returns to me that local url where the file is.
Unless I sincronize the asyncronic call but I don't know how to do
that.
3) I'm sure that the link its correct because just for be sure i test
to show it in an alert message and it's ok.
4) I will try with generics but I don't think it's the problem because
this should work on previous versions that doesn't support java 5.
Thanks for the help, any suggestions will be very helpful
Federico.

Re: Open a local file with GWT
Well, maybe the matter is that Window.open will be caught by some
popup blockers. Why dont you use an Anchor element with a _blank
target, this will open a new window and it's not blocked by browsers.
First do an asynchronous call to retrieve the url and once you have
show and anchor element with a _blank target with your url, the user
just needs to click it to download the file

Re: Open a local file with GWT
Did you try using a PipedReader?

Re: Open a local file with GWT
O.K.
1) what is pdfLink? is that supposed to be link?
2) if you have any kind of Popup blocker, attempting to open a window
from the callback will fail. if you want to open a window, it has to
happen as a direct result of a user action (onClick, etc)
3) if link is a path to a filesystem file are you sure it is correct?
(this is sneaky, but just might work)
4) Technically not causing a problem but, use generics.
AsyncCallback cb = new AsyncCallback{
public void onSuccess(String result) ...
}

Re: Open a local file with GWT
You CAN'T read files from filesystem from plain javascript. Applets or
Gears are a way to go. Another way is that user just opens your file
instead of downloading it ;-)

Open a local file with GWT
Hi I'm trying to make a function that let the user download a file
from my application and see it. I could copy the file from server to a
local root but when I've tried to open it, does it work on hosted mode
but in web mode fails always, no matter what browser I try(IE 7,
Firefox and Chrome).
My code is the next one:
private void openDocument(String documentName) {
final ManagerExportAsync manejador =
ManagerExport.Util.getInstance
();
AsyncCallback callback = new AsyncCallback(){
String link;
public void onSuccess(final Object result) {
link = (String)result;
Window.open(pdfLink,"_blank","");
}
public void onFailure(Throwable caught){}
};
manejador.openDocument("User",userId, documentName,callback);
}
The String link result is something like this "file///:C:/test.jpg"
I don't know what it's wrong. I read somewhere that the problem could
be that I'm calling the Window.open inside the callback but I really
don't know what is wrong coul someone give me a hand?
Any suggestions?
Thanks!
Federico.
