请教一个问题，在jsp文件中，怎么通过输入流，输出流像服务器写文件啊，我像本地文件写呢，可是放到jsp中，上传服务器，怎么说我路径不对啊，我改了路径啊
不晓得像服务器上写文件要别的东西吗

   <%FileWriter out1=new FileWriter("/2.js");  地址是这么写吗
  BufferedWriter outbuffer=new BufferedWriter(out1);
  outbuffer.write("var interval_time=5\r\n");
  outbuffer.write("var focus_width=260\r\n");
  outbuffer.write("var focus_height=180\r\n");
  outbuffer.write("var text_height=18\r\n");
  outbuffer.write("var text_align= 'center'\r\n");
  outbuffer.write("var swf_height = focus_height+text_height\r\n");
  outbuffer.write("var pics= 'image/4.jpg|image/1.jpg|image/2.jpg|image/3.jpg'\r\n");
  
  outbuffer.write("var links='");
  
  outbuffer.write(s[0]);
  outbuffer.write("|");
  outbuffer.write(s[1]);
  outbuffer.write("|");
  outbuffer.write(s[2]);
  outbuffer.write("|");
  outbuffer.write(s[3]);
  
  
  
  
  
outbuffer.write("\r\n");
outbuffer.write("var texts='");
outbuffer.write(s[4]);
  outbuffer.write("|");
  outbuffer.write(s[5]);
  outbuffer.write("|");
  outbuffer.write(s[6]);
  outbuffer.write("|");
  outbuffer.write(s[7]);
  outbuffer.write("\r\n");
  
  
  
  
outbuffer.write("document.write('<object classid=\"clsid:d27cdb6e-ae6d-11cf-96b8-444553540000\"\r\n");
  outbuffer.write("codebase=\"http://fpdownload.macromedia.com/pub/shockwave/cabs/flash/swflash.cab#version=7,0,0,0\" width=\"'+ focus_width +'\" height=\"'+ swf_height +'\">');\r\n");
   outbuffer.write("document.write('<param name=\"movie\" value=\"pixviewer.swf\"><param name=\"quality\" value=\"high\"><param name=\"bgcolor\" value=\"#ffffff\">');\r\n");
    outbuffer.write("document.write('<param name=\"menu\" value=\"false\"><param name=wmode value=\"opaque\">');\r\n");
     outbuffer.write("document.write('<param name=\"FlashVars\" value=\"pics='+pics+'&links='+links+'&texts='+texts+'&borderwidth='+focus_width+'&borderheight='+focus_height+'&textheight='+text_height+'&text_align='+text_align+'&interval_time='+interval_time+'\">');\r\n");

  outbuffer.flush();
  outbuffer.close();

我之前做过一个STRUTS框架的上传功能 处理过类似问题（代码忘记在哪了，找到了传上来）
你可以打印你的地址
看看是否正确
然后进行修改

谢谢，往本地可以写，网服务器上写，说目录不正确，不晓得这个目录怎么写，或者还要什么别的东西
