File upload with FormFile loses filename capitalisation.

[Ashley Roper]

Hi,

I am finding that all file uploads in our site use struts FormFile, which works rather well, I have however noticed that the filenames are always in lowercase, no matter what they were before upload.

I cannot see anything in the documentation that explains this.
The problem exists across browsers.
Most users will be use Windows however issue also occurs on Linux.

Current thinking is to create another field on the Struts Form in which to store the filename, and to have JavaScript populate this value using onChange.

Any explanations or neater solutions would be much appreciated.

My rather crude work around :

<script language="javascript" type="text/javascript">
function saveFilename()
{
    $('input[name="theFileName"]').val($('input[name="theFile"]').val());
}
</script>
<html:form method="post" enctype="multipart/form-data" action="/importFile.do">
    <html:hidden property="theFileName" />
    <table>
        <tr>
            <td>
                Choose a file to import
            </td>
            <td>
                <html:file property="theFile" onchange="saveFilename();"/>
            </td>
        </tr>
	        <td>
	            <html:submit  property="method">
	                <bean:message key="web.button.ok"/>
	            </html:submit>
                    <html:submit property="method">
                        <bean:message key="web.button.cancel"/>
                    </html:submit>
	        </td>
    </table>
</html:form>

Using the theFileName String value as the real filename, capitalisation preserved.
This issue was with Struts 1 by the way.

Any alternate solutions or an explanation for the issue would still be appreciated.
