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

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.
AsyncCallbackString cb = new AsyncCallbackString{
public void onSuccess(String result) ...

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
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

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
I'm not trying to read files from filesystem from plain javascript, I
want to open a new browsers window with a local url. The browser
should decide how he will open this file.

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 ;-)
