<p>
<p>使用 JSP/ Servlet上载文件正成为一项常用的任务。以下是一个简单的例程，使用了jspsmart的一个免费的组件。你可以在JSPSMART站点进行下载。 <br>
<br>
1. Html File <br>
<html> <br>
<body> <br>
<script LANGUAGE="javascript" SRC="JSFunction.js"> <br>
</script> <br>
<script language="JavaScript"> <br>
<!-- <br>
function checkForm(){ <br>
<br>
if (document.uploadform.adsImage.value==""){ <br>
alert("You must choose what image file to upload!"); <br>
return false; <br>
} <br>
document.uploadform.submit(); <br>
} <br>
function cancelUpload(){ <br>
window.close(); <br>
window.opener.focus(); <br>
} <br>
//--> <br>
</script> <br>
<form name="uploadform" method="post" <br>
action="uploadImage.jsp" ENCTYPE="multipart/form-data" <br>
target=_self> <br>
<center> <br>
<table border="1" width="65%"> <br>
<tr> <br>
<td colspan=2 nowrap align=center>广告图片上载</td> <br>
<br>
</tr> <br>
<tr> <br>
<td width="15%" nowrap >广告图片:</td> <br>
<td width="50%" nowrap><input type="file" <br>
name="adsImage" size="20"></td> <br>
</tr> <br>
<tr> <br>
<td align="center" colspan=2 > <br>
<input type="button" value="upload" onclick="return <br>
checkForm();" > <br>
&nbsp;&nbsp;&nbsp; <br>
<input type="button" value="Cancel" onclick="return <br>
cancelUpload();"> <br>
</td> <br>
<br>
</tr> <br>
</form> <br>
</table> <br>
<!-- <br>
<a href="Javascript:window.close();">close this window</a> <br>
--> <br>
<script language="JavaScript"> <br>
<!-- <br>
this.focus(); <br>
//--> <br>
</script> <br>
</body> <br>
<br>
2. JSP File <br>
<%@ page language="java" import="com.jspsmart.upload.*, <br>
java.sql.*,java.util.* "%> <br>
<%-- use SmartUpload bean --%> <br>
<jsp:useBean id="mySmartUpload" scope="page" <br>
class="com.jspsmart.upload.SmartUpload" /> <br>
<br>
<% <br>
<br>
//Initialization <br>
mySmartUpload.init(config); <br>
mySmartUpload.service(request,response); <br>
<br>
//Set Restriction <br>
mySmartUpload.setAllowedFilesList("gif,bmp,jpeg,jpg"); <br>
mySmartUpload.setTotalMaxFileSize(51200); <br>
<br>
<br>
<br>
// Upload <br>
try{ <br>
mySmartUpload.upload(); <br>
} <br>
catch(Exception e){ <br>
out.println("<font color=red>Upload File Fail!</font> <br>
<a href= <br>
\"JavaScript:window.history.back();\">back</a><br>"); <br>
out.println("<UI>Notes:</UI>"); <br>
<br>
out.println("<UL>You must set correct File <br>
Name.</UL>"); <br>
out.println("<UL>You file size must be less than <br>
50K.</UL>"); <br>
out.println("<UL>You can only upload .Gif .jpeg .jpg and <br>
.bmp files.</UL>"); <br>
<br>
return; <br>
<br>
} <br>
//save file to disk <br>
mySmartUpload.getFiles().getFile(0).saveAs("/" + <br>
"FileName"); <br>
<br>
<br>
<br>
%> <br>
<br>
<br>
<br>
3. Servlet File (you can do it yourself) <br>
