I have a strange situation where the components on a form are dynamically
built and the form is submitted to an action method "create" on a Controller
class. Basically the form looks like this:
HtmlPanelGrid
(ROW 1)
--HtmlOutputText
--HtmlPanelGrid
----HtmlSelectOneRadio
----HtmlInputFileUpload
(ROW 2)
--HtmlOutputText
--HtmlPanelGrid
----HtmlSelectOneRadio
----HtmlInputText
Once form is submitted from the "create" method on the Controller class I
can lookup the values of the HtmlInputText by doing:
[CODE] String txtBoxValue = request.getParameter(htmlInputText.getId());
[/CODE]
However, I cannot figure out how to access the file that was submitted (the
HtmlInputFileUpload). I tried using commons-fileupload as below:
[code]
public InputStream getFileFromRequest(String fieldName, HttpServletRequest
request)
{
FileItemFactory factory = new DiskFileItemFactory();
ServletFileUpload upload = new ServletFileUpload(factory);
InputStream uploadedStream = null;
List items;
try
{
// Parse the request
items = upload.parseRequest(request);
System.out.println("items.size() "+items.size());
}
catch(FileUploadException fue)
{
System.out.println("Exception trying to parse request for
FileItems");
System.out.println(fue);
throw new RuntimeException(fue);
}
//walk through items in the form
....
[/code]
but the items.size() is always zero. I am thinking JSF is intercepting this
form before I pass it to the "parse" method and somehow this makes the form
un-parsable" for commons-fileupload. If this is true...how can I get the
file that was submitted before JSF messes with it...or better yet, how can I
get the file that was submitted directly from JSF?
