一个文本上传Bean的例子

我在这个网站看见了几篇关于图片上传的bean，但是没有看见文本上传的bean 于是就写了个

上传文本的bean.此程序在tomcat4.1调试成功

package up;

import Java.io.*;

import javax.servlet.http.HttpServletRequest;

import javax.servlet.http.HttpServletResponse;

import javax.servlet.ServletInputStream;

public class upjspBean {

int count=0;

int i=0;

String dataString=null;

String lastString=null;

public void doUpload(HttpServletRequest request) throws

IOException {

int indexof;

int n=0;

byte[]tmpdata=new byte[65536];

FileOutputStream fo=new FileOutputStream("a.txt");

BufferedOutputStream bo=new BufferedOutputStream(fo);

DataOutputStream file=new DataOutputStream(bo);

ServletInputStream si = request.getInputStream();

BufferedInputStream b i=new BufferedInputStream(si);

DataInputStream data=new DataInputStream(bi);

count=data.available();

try{while (true) {

tmpdata[count++] = data.readByte();

}}

catch(EOFException e) {data.close();}

dataString=new String(tmpdata,0,count);

indexof=dataString.indexOf("Content-Type:");

dataString=dataString.substring(indexof);

indexof=dataString.indexOf("

");

dataString=dataString.substring(indexof+4);

indexof=dataString.indexOf("-----------------------------7d3");

dataString=dataString.substring(0,indexof-2);

tmpdata=dataString.getBytes();

i=tmpdata.length;

file.write(tmpdata,0,i);

file.close();

}

public int getCount() {

return(i);

}

}
