Re: Problem with empty file upload field

[Joey Ebright]

Wow, surprised you never got an error!?! I am using struts 1.1b3 and recieve an IllegalArgumentException (argument type mismatch) from BeanUtils.populate when the user does not specify a file to upload (leaves form entry blank).
I verified the following:
- I have my form's enctype set to "multipart/form-data"
- I have my form bean's property for the file to upload declared as type FormFile
- Even though my struts-config says that my form bean should validate (validate="true"), the validate() method is never called. The exception comes before the validate() method gets a change to be invoked. This leads me to assume that it is the binding of the html form values to the form bean that is the culprit...

I have also verified this behavior under struts 1.02. If you do not receive this error, then can you tell me what version of struts you are running?

Thanks!!!

What happens if the user does not specify a file to upload and you submit the form? Do you get an error? How do you handle this?

Just for info - I use struts 1.3b nb and built upload func into my
current app - no problem. Remark what i corrected from wrong in first
step :

1. <html:form action="...enctype="multipart/form-data"> <- !!!!!!

2. use as property a property of type FileForm from org.apache.struts -
it was a crazy idea to me to put a Form into a Form first ;-)

3. erhm, and don�t open input stream on blank filename

Ciao J�rg

I too have the same problem - whenever the user does not supply a file to upload I get an exception. I have tried the 1.1-b3 release of

struts

and the 1.6 release of the commons and recieve the same error from BeanUtils.populate - IllegalArgumentException...

Have you made any progress on this front?
