FormFile has a "getFileSize" or similar method that you can use to check the size in your processing Action (server side). There, you can also determine the file name and check the extension (probably that will be good enough for "type" checking).
In addition, this is one area where I think client side validation (JavaScript) is useful. You want your users to find out their input was invalid *before* an upload if you can help it. Something I have done that works pretty well is to disable the form submit with JavaScript until at least the file name extenstion (file type) that the user has entered matches a value from a predetermined list (.jpg, .gif, etc.). I don't know how to check the file size on the client however, or whether that's even possible (because of security reasons). I have some example code I could post later if you are interested, but it's all pretty straightforward.

Everything works fine but I want to filter the type of file that the user may upload. And also limit the file size. How can I handle this with Struts ? I didn't manage to do this in simple html code (apparently because most of browsers do not respect html specifications)and I suspect that I'll need to check in my Action code. Am I right ?
