<!--
The most important part is to declare your form's enctype to be "multipart/form-data",
and to have a form:file element that maps to your ActionForm's FormFile property
-->
<html:form action="upload-submit.do?queryParam=Successful" enctype="multipart/form-data">
<p>Please enter some text, just to demonstrate the handling of text elements as opposed to file elements: <br />
<html:text property="theText" errorStyle="background-color: yellow"/></p>
<p>Please select the file that you would like to upload: <br />
<html:file property="theFile" errorStyle="background-color: yellow" /></p>
<p>If you would rather write this file to another file, please check here: <br />
<html:checkbox property="writeFile" /></p>
<p>If you checked the box to write to a file, please specify the file path here: <br />
<html:text property="filePath" errorStyle="background-color: yellow"/></p>
<p>
<html:submit />
</p>
</html:form>

<h3>Request Parameters</h3>
<p>Display the request parameter values to show that the multipart request
retains them in the event of a validation error.</p>
<b>The Text:</b> <%= request.getParameter("theText") %></br>
<b>Write File:</b> <%= request.getParameter("writeFile") %></br>
<b>File Path:</b> <%= request.getParameter("filePath") %></br>
