Hello,
First of all, there is ambiguity in your question. I'm not sure how the
above would tie into a "wicket-specific" question, unless you want to
create an XForm-->XHTML renderer/processor using Wicket as the
underlying technology (which is not a good idea IMHO). In any case:
1) Are you asking whether Wicket can be used to render XForms files (as
in the the XForms specification at http://www.w3.org/TR/xforms11/).
In this case, the answer is NO, I'm not aware of such an XForm renderer.
You could create a custom Wicket component that is given an XForm
definition document and uses it to render an XHTML page, but that is a
lot of work (and probably not a very efficient way to do it, as you
would ideally use XSLT or something along those lines to do XML-->XML
transformation. There are available open-source tools like Orbeon (see
http://www.orbeon.com/) which can give you this kind of functionality
(including processing of the "XForm submission").
Now, regarding the online/offline issue:
2) Do you have a rich client application that can render the XForms
(e.g. using Swing) and allow the user to save such forms locally? In
that case, you would need to write code that submits the forms when the
rich client has network access. The submission should probably go to
some servlet (e.g. an Orbeon-managed URL). Again, I don't think this
would be wicket-related.
3) If you have a web-based application for this (e.g. a bundled Tomcat
running on the user machine, which they access via the browser) then the
principle is a combination of (1) and (2): You would need:
a) to render the forms using something like Orbeon to present HTML to
the browser
b) to store the form submission to the local FS (or a locally running DB
which could be something like Derby)
c) to implement an "uploader" where the user can send "locally saved"
forms to a central server (same as what I talked about in (2) above)

Hi,
Rendering a document in the Xforms or storing it in a database is as you
have suggested
ok.
The issue is there when you have xform controls inside a wicket
application
instead of HTML document(form) and take the imput and stores them into a
database.
Am I explaining my position clearly ?
Regards
