Multiple form upload
Author: pperliti Posts: 5 Registered: 4/29/02 Jul 19, 2004 12:21 PM
Hi everybody.
I‘m trying to use a form to upload several files, all at once.
I use Struts and Commons facilities (that is the FormFile interface).
Here‘s my action form:
public class AttachmentForm
extends ActionForm {
/* Files to upload */
private FormFile[] uploadedFiles;
public FormFile[] getUploadedFiles() {
return uploadedFiles;
}
public void setUploadedFiles(FormFile[] uploadedFiles) {
this.uploadedFiles = uploadedFiles;
}
}
And this is the html code I use to populate the action form (I‘m using Velocity, but I don‘t think this is really important):
...
<form name="uploadForm" method="post" enctype="multipart/form-data" action="(...my action...)">
...
Attachment 1: <input type="file" name="uploadedFiles"/>
Attachment 2: <input type="file" name="uploadedFiles"/>
Attachment 3: <input type="file" name="uploadedFiles"/>
...
</form>
...
Everytime I submit the form I obtain this exception:
javax.servlet.ServletException: BeanUtils.populate
org.apache.struts.util.RequestUtils.populate(RequestUtils.java:1254)
org.apache.struts.action.RequestProcessor.processPopulate(RequestProcessor.java:821)

javax.servlet.http.HttpServlet.service(HttpServlet.java:810)
If I adjust the java source to manage one file only (ie. FileForm instead of FileForm[]) it works, but as I try to use an array I get the Exception.
I use struts 1.1 on Windows XP platform and Tomcat 5.0.24.
Have you got any ideas? Is it a bug of commons-beanutils?
Thanks in advance,
Paul

Hi!
I am having the same error. I need to upload N files, being N dynamic between requests.
Have you solved your problem?
Any hint would be appreciated.

Attachment 1: <input type="file" name="uploadedFiles"/>
Attachment 2: <input type="file" name="uploadedFiles"/>
Attachment 3: <input type="file" name="uploadedFiles"/>
give unique names to the name of the file fields..

Hi!
Thks for your reply.
If I define mutiple file inputs :
<input type="file" name="uploadFile" ...
><input type="file" name="uploadFile" ...
...
and define a variable on the Struts form like;
private FormFile[] uploadFile = null;
Struts throws the exception below while trying to fill the array.
I can fill arrays of Strings, ints,....but with the FormFile I am having this Exception. I would prefer to use Struts mechanism to upload files instead of doing things "manually". Any help would be appreciated.
Thanks in advance,
Victor Batista

Instead of this:
Attachment 1: <input type="file" name="uploadedFiles"/>
Attachment 2: <input type="file" name="uploadedFiles"/>
Attachment 3: <input type="file" name="uploadedFiles"/>
use this and try it:
Attachment 1: <input type="file" name="attachment1"/>
Attachment 2: <input type="file" name="attachment2"/>
Attachment 3: <input type="file" name="attachment3"/>
You‘re uploading three files, all with the same request parameter name. Heck, that would cause me to bust a blood vessel.

======================= 從這里開始 ==============================
I‘ve been battling this for some time now and here is how you get around it:
Jsp page:
<html:file property=‘<%="referenceFormFile["+i+"]"%>‘ size="40"/>
（注意是帶[]）
where i is some counter generated by for loop or iterator
Action form:
Create property -> private FormFile[] referenceFormFile;
Add the following methods:
public FormFile[] getReferenceFormFile()
{
return referenceFormFile;
}
public void setReferenceFormFile(FormFile[] referenceFormFile)
{
this.referenceFormFile = referenceFormFile;
}
public FormFile getReference(int index)
{
return referenceFormFile[index];
}
public void setReference(int index,FormFile reference)
{
referenceFormFile[index] = reference;
}
Make sure to initialize array within reset method and on load
I did it this way:
/**
* initialize array of file upload
* @param request
*/
public void initArray(HttpServletRequest request)
{
referenceFormFile = new FormFile[MAX_NUMBER_REFERENCES];
}
Make sure you call it from reset method and when action form is created
Hope it helps,
Sincerely Roman
