Using Struts to save files

[Karthik Krishnamurthy]

I am writing a file manager software using struts. I have written the code to upload the file easily using the html:file tag.
However when the user has to see the files that have been uploaded, I need to give him the ability to save the uploaded file (name displayed as a link) to disk.
How do i do that.
Thanks Karthik

Hi Karthik,

First of all, I have to ask you to change your display name to comply with our naming policy -- we require people to use real, or at least real-looking names.

Thanks.

As to your question about downloading the files, the general approach is to have a Servlet (Struts Action class in your case) proxy the filesystem for the client. For example, if your upload stores the uploaded files under "/var/data", you'd want your DownloadAction to serve a request to, say "DownloadAction.do?file=sample.txt", by streaming the file "/var/data/sample.txt" to the web browser.

Karthik,

I wrote a Struts application that demonstrates File Upload and File Download:

There seems to be a lot of questions about file upload/download.

Have a look at Struts Recipes, recipe 2.9

Hi Kartik,

I went through the code of your applicationa and i have a doubt. In the "fileList.jsp", there is this logic:iterate tag:

<logic:iterate id="file" name="files">

What does this "files" refer to? there is no such field in the form associated with this JSP. Please clarify the same.
