下面是Struts多文件上传代码:
jsp页面:



   <html:form action="/upload.do?action=upload" method="post" enctype="multipart/form-data">

	<html:file property="file1"/><br>

	<html:file property="file2"/><br>

	<html:file property="file3"/><br>

	<html:file property="file4"/><br>

	<html:file property="file5"/><br>

	<html:submit>上传</html:submit>

  </html:form>
