Опитайте кода по-долу (качване на общ файл на Apache)
index.jsp
<html>
<head><title>Upload page</title></head><body>
<form action="UploadServlet" method="post" enctype="multipart/form-data" name="form1" id="form1">
<center>
<table border="1">
<tr>
<td align="center"><b>Multipale file Uploade</td>
</tr>
<tr>
<td>
Select file: <input name="file" type="file" id="file">
</td>
</tr>
<tr>
<td>
Select file:<input name="file" type="file" id="file">
</td>
<tr>
<td>
Select file:<input name="file" type="file" id="file">
</td>
</tr>
<tr>
<td align="center">
<input type="submit" name="Submit" value="Submit files"/>
</td>
</tr>
</table>
<center>
</form>
</body>
</html>
Или можете също да използвате кода по-долу за jsp (ако използвате този код, натиснете ctrl за да изберете няколко изображения)

<table border="1">
<tr>
<td align="center"><b>Multipale file Uploade</td>
</tr>
<tr>
<td>
Specify file: <input name="file" type="file" id="file" multiple>
</td>
</tr>
<tr>
<td align="center">
<input type="submit" name="Submit" value="Submit files"/>
</td>
