Joey,
Since you need to cover your butt on both sides, client and server, do a
simple javascript validation on the form as it is being submitted to make
sure something was entered in the file input field.
function validateUploadForm(theForm) {
if (theForm.myFile.value=="") {
alert("Please select a file to upload from your workstation by clicking
the Browse button.");
theForm.myFile.focus();
return false;
}
}
After that, your action should be smart enough to check for any of the
obvious file (FileInputStream) properties, like contentType, fileName or
fileSize (to be >0). Look at the API for java.io.FileInputStream
