Can i use html:file with other input fields?

Hi,

Can i use html:file with other input fields? I got null for formfile in the validate method but another fields is fine.

Any comments is welcome.

thanks,
anurak

Yes, you can, but you must remember to specify enctype="multipart/form-data" in your <html:form> tag.

hi Merrill,

Thanks for your reply,I already set enctype="multipart/form-data".
Before i added another input type to jsp, it worked(file uploading).
After i add another input type, i got null for formfile but another attributes value ok.

thanks,
anurak

I'm not entirely sure that it will work for validation. When there is both file data and other data, Struts has to go through some extra steps. By the time the data reaches your Action class, everything should work, but it may not work in the validate method of your ActionForm. Check it and let us know: is the FormFile null when you try to access it in your Action class?

Yes, it also null in action.

Show us the code in your ActionForm, Action class, and JSP.

Here's another possibility: Struts will return null for the FormFile if it determines that the size of the file exceeds the maximum size set in the <controller> stanza of your struts-config.xml file. Make sure that the file being uploaded does not exceed this size.

The file that i used for testing is very small in size.

Hey, thank you very much for you help.
