100分，高手请帮忙看看这个javabean

本文导语: 我得到一个文件上传的例子，但我不知道该如何设置文件上传到服务器特定的目录去。 main.htm ----------- up.jsp ----------- UpBean.java package up; import java.io.*; import javax.servlet.http.HttpServletRequest; import javax.servlet.http.HttpS...

我得到一个文件上传的例子，但我不知道该如何设置文件上传到服务器特定的目录去。
main.htm

-----------
up.jsp

-----------
UpBean.java
package up;

import java.io.*;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import javax.servlet.ServletInputStream;

public class UpBean {
    public void doUpload(HttpServletRequest request) throws IOException{
        PrintWriter pw=new PrintWriter(new BufferedWriter(new FileWriter("Demo.out")));
        ServletInputStream in = request.getInputStream();
        int i = in.read();
        while (i != -1) {
            pw.print((char) i);
            i = in.read();
        }
        pw.close();
    }
}

能根据这些代码，修改修改，具体给个方案实现调用main.htm(提交后文件保存到服务器c:upfile这个目录下)吗？谢谢

给你一段代码，就是用的japsmart,可以在一个servlet里得到数据流后把它写到一个文件里就行了。
private static Data getHttpRequestData(HttpServletRequest req, HttpServletResponse res, ServletConfig servletConfig)
        throws LIException
    {
        Map map = null;
        boolean needWordChange = true;
        if("GET".equals(req.getMethod()))
        {
            if(req.getQueryString() != null)
                map = HttpUtils.parseQueryString(req.getQueryString());
            else
                return null;
        } else
        if("POST".equals(req.getMethod()))
            try
            {
                if(req.getContentType().indexOf("multipart/form-data") != -1)
                {
                    needWordChange = false;
                    Hashtable aMap = new Hashtable();
                    SmartUpload smartUpload = new SmartUpload();
                    smartUpload.initialize(servletConfig, req, res);
                    smartUpload.setMaxFileSize(0x4c4b40L);
                    smartUpload.setTotalMaxFileSize(0x4c4b40L);
                    smartUpload.upload();
                    System.out.println("**multipart/form-data: Number of files = " + smartUpload.getFiles().getCount());
                    System.out.println("**multipart/form-data: Total size(bytes) = " + smartUpload.getFiles().getSize());
                    int count = smartUpload.getFiles().getCount();
                    for(int i = 0; i
