Validating an image upload via "Validator-form.xml"

Hi,

I tried searching the internet but couldn't get anything regarding this topic.

I have a <html:file> in my jsp which uploads an image to the server. I want to validate this using the validator-rules.xml but can't figure out how to go about it.

Can someone please help me on how to define the rules in my validator-form.xml (this contains my validation for all the forms), so that I can validate the file to be uploaded.

Thanks in advance.

What are you trying to validate? That a file name was entered? That a file exists?

Trying to validate whether the file is within the size limit and also if it is an image file.

I know I can do these validations in action level manually but I want to validate using the struts provided validation framework. Possible?

Not that I know of. I believe file upload is delegated to the Apache Commons FileUpload package, so file size limitations are enforced by it.
