Multiple File Upload using Struts

[Ambika Jain]

I need to do a Multiple File Upload using Struts in my web app.
Its easy to do a single file upload using the FormFile.
But how do we implement for multiple file upload.

Any help will be appreciated.

Thanks

"Multiple file upload" in that the user can select a fixed number of files, or that the user can select any number of files? In the first case where you the user can select a fixed number of files you just need to put multiple FormFile properties in your form. I recall doing some research into the second case and it is not supported. As I recall, some browsers will let the user select multiple files but it is not really a supported feature and not something supported by Struts.

I recently had been doing research on doing multiple file uploads. I did find this address. It isn't using struts. Take a look at it though. It still may be helpful.

Thanks Daniel .

Your link is very helpful.
I am able to achive this using few changes in the ActionForm file.
Just wanted to know if this is right way of doing it ?

            private ArrayList formFiles = new ArrayList();
            private FormFile f;
            
            public void setTestFile(int iIndex, FormFile formFile)
            {
                f = formFile;
                this.formFiles.add(formFile); 
            }           
            public FormFile getTestFile(int iIndex)
            {
               while(this.formFiles.size() <= iIndex)
                {
                    this.formFiles.add(f); 
                }
                return (FormFile) formFiles.get(iIndex); 
            }
            public ArrayList getTestFiles()
            {
                return this.formFiles; 
            } 

Thankyou.

Hi Ambika,

Any update with how you went ahead with this ?
How are you processing this approach in the action class.
I am stuck in a similar position now.


TIA
