　　js|攻略|上传一、首先下载jspsmartupload组件
http://dboy520.51.net/cgi-bin/newjavajia/downcount.php?id=22 (本站地址)
http://www.jspsmart.com

二、将目录jspsmartupload/wib_inf/classes中的内容拷贝到网站所在的实际目录中的WEB-INF中（resin是这个目录，其他的可能是classes,具体请查阅jspsmartupload/help/setup.htm)

三、如果是resin运行JSP，请在resin的conf/resin.conf中的
<web-app>和</web-app>中加入：
<path-mapping url-pattern=’/upload/*’ real-path=’f:\jsp\jspsmartupload\upload’/>

四、上传界面的代码如下：(文件名：insert.htm)
<FORM METHOD="POST" ACTION=" uploadfile.jsp" ENCTYPE="multipart/form-data">
<INPUT TYPE="FILE" NAME="FILE1" SIZE="50">

<INPUT TYPE="FILE" NAME="FILE2" SIZE="50">

<INPUT TYPE="FILE" NAME="FILE3" SIZE="50">

<INPUT TYPE="FILE" NAME="FILE4" SIZE="50">

主题：<input type="text" name="text1" >

<INPUT type=submit value=写　完 name=ok>
</form>
注意上面的real-path目录

五、uploadfile.jsp的代码如下:
<%page contentType="text/html;charset=gb2312"
language="java"
import="com.jspsmart.upload.*"%>
<jsp:useBean id="mySmartUpload"
scope="page"
class="com.jspsmart.upload.SmartUpload" />

<HTML>
<BODY >
<H1>文件上传JSP</H1>
<HR>
<%
int count=0;

//定义目标目录
String destination="/upload/";
mySmartUpload.initialize(pageContext);

//文件上传
mySmartUpload.upload();
//获得文本的内容
String content = mySmartUpload.getRequest().getParameter("text1");
//显示文本的内容
out.println(content);
//上传的情况统计
for (int i=0;i<mySmartUpload.getFiles().getCount();i++){
com.jspsmart.upload.File myFile = mySmartUpload.getFiles().getFile(i);
if (!myFile.isMissing()){
myFile.saveAs(destination+ myFile.getFileName());
out.println("文件名称= " + myFile.getFieldName() + "
");
out.println("文件大小= " + myFile.getSize() + "
");
out.println("文件名称= " + myFile.getFileName() + "
");
out.println("文件大小= " + myFile.getFileExt() + "
");
out.println("文件路径名= " + myFile.getFilePathName() + "
");
out.println("文件类型= " + myFile.getContentType() + "
");
out.println("ContentDisp = " + myFile.getContentDisp() + "
");
out.println("MIME类型 = " + myFile.getTypeMIME() + "
");
out.println("SubTypeMIME = " + myFile.getSubTypeMIME() + "
");
count ++;
}
}

out.println("
可以上传" + mySmartUpload.getFiles().getCount() + "个文件
");
out.println(count + "个文件已经被上传");
%>
</BODY>
</HTML>
以上就是JSP文件上传的全过程,Good Luck!
