Hi Roberto,
You may want to try the following:
Create a separate servlet for file upload using a library like this one
http://jakarta.apache.org/commons/fileupload/
and register it with the http registry. You can access the servlet by
using the browser widget.
I found a pretty cool demo (using rails, but anyway) here:
http://sean.treadway.info/demo/upload/
Maybe you can even implement this kind of visual feedback as soon we
provide the progress bar ...
Regards, Jochen

Thank you Jochen, that the help I need, I hope to get my app ready in 2
weeks, My app is about Curriculums Vitae, I need upload file in order to
include the user photo, I can begin without photo, but I think that is a
good feature for my app.
A progress bar for upload files could by really cool ;-)
Regards.
Roberto.

Hi again,
I'm doing it, Using Apache commons fileupload (by the way, I had a rare
problem with version classes in classpath in run-time) and a Servlet,
Now, I can upload a file to my server, but I have a concept doubt:
I'm using a Browser control in a modal Dialog, My Servlet standard out
writes on such Browser in my dialog, I would like to show, as servlet
answer, a Dialog with WRT Controls, preview of uploaded file, labels,
buttons, etc.
How can I do it ? Now I have a "standard" servlet I can do it with
"HTML-Tradicional-way" but I would like to do it as "RAP-way"
I was reading something (javadoc) about IServiceHandler but I don't know
if it is the solution.
Regards.
Roberto

Hi,
the IServiceHandler would make no difference to your approach with the
servlet. At the moment there is no build in support for fileupload with RAP.
If you are using a fileupload within a html document the form data that
should be sent to the server is submitted with the post method and the
content has to be base64 encoded. This makes it different for a direct
integration with RAP at the moment (By the way there is a integration with
the W4T library which was the initial code contribution of Innoopract for
RAP, so we think we will also be able to come up with a solution for RAP).
One way your additional servlet and the RAP application may interact is the
common session object. You could use the session to exchange information
between them. But as I don't know enough of your UI-needs it is difficult to
provide any further suggestions.
Ciao

Hi Frank, I've already thoungh about using Session to share data but I
would like to launch an event to "RAP-side" in order to read and manage
these data, How can I do that ?
