File Chooser dialog needed
Hello,
I am working on wicket. I need to open a filechooser dialog or a file open =
dialog (like we have in JFileChooser).
I am currently unable to implement it from my wicket page. All I want is a =
file chooser dialog showing only directories , user chooses nd I get back t=
he path selected.
I tried to call a JFielChosser (sinwg) thorught wicket but there seems to b=
e some problem, the dialog cmes in a different location first time and in t=
he center of the 2nd time onwards, I guess the modality is wrong. The JFile=
Chooser needs a Component object type as its parent. But I am unable to pas=
s it from thewicket class. It cannot be cast to a Component or Window.
Kindly help me out on this.
Thanks,
Shyam

Posted by Jeremy Thomerson <je...@wickettraining.com>.
Again, you can't do this in a standard HTML form. For something like this,
you will need to use something like an applet. Put simply, the browser does
not give you folder locations, and even if it did, your server couldn't list
or grab files from the client's folder. And, the browser won't
automatically upload an entire folder of anything. HTML has a file input
only for files - not directories. Allowing anything different would be a
big security risk.
As far as letting them choose where to save it on the server - why would you
do this? You can accomplish this by creating or using some sort of browse /
select component, but this is typically a bad idea - why do you want to give
a user access to your server file system over a webapp? It might be good to
go back and look at your real requirements and evaluate what MUST be done,
and then how best to accomplish it. (note - there may be certain use cases
where you do need to do this, but they are very rare, and almost
non-existent on a public app - which this may not be)
Anyway, hope this helps.

Thanks for the response.
I have a similar requirement for upload tooo. I want to make a Browse
button, which accepts folder locations, and uploads all the files in that
location. uploading the data from the file is fine... i can handle
but how to create a button, which accepts folder locations of both client
system and server system
?

You simply can't do this in web apps. You don't choose where to write
something to - you don't have access to write anything to the user's
computer. All you can do is give the user a file to download, and the
browser will automatically ask them for what folder they want to save it
to. For this, search Nabble or Google for "DownloadLink".
Give the user a link (DownloadLink) to a file. They click it. The browser
opens your dialog for you.

Thanks for your reply.
My main aim of this task is to download an item into the directory user selects.
So need to open a file dialog to help user choose a directory and then from it get the path user chose, so as to proceed with my
download.
So as you can imagine for this, i have a browse kindoff button for user to chose a directory and as it closes, need to display the path selected in a text field.
The button as well as textfield stand on a wicket page. Just the action of opening a file browser is what i want.
I am very new to wicket. Could you pls explain more on what i would have to do to open such a dialog nd then get the path selected ?
A code example would be appreciated.
Thanks

If you really want to do that, make sure you install your web application in
each user's computer... :-)
Just to make sure the JFileChooser will actually work. And if you warn the
user about something, don't use a javascript alert. JOptionPane is your
friend here too!

Swing classes are not in the same heirarchy as Wicket's and the two are not
made to work together. What you need is to add an <input type="file" ....
/> and a FileUpload (Wicket class). However, you can't have a user just
select a directory from their browser - this is a limitation of web apps.
Besides, what could you possibly do with that directory path once you had
it? You don't have access to their local computer....
