上面的是Upload.java
下面这个是UploadServlet.java,这两个是放在 Eclipse的src中的，见截图：

package pageconnection;

import java.io.IOException;

import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import org.apache.commons.fileupload.FileItem;
import org.apache.commons.fileupload.DiskFileUpload;
import org.apache.commons.fileupload.servlet.ServletFileUpload;

public class UploadServlet2 extends HttpServlet{

protected void doPost(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
System.out.println("Success!");

String select = request.getParameter("select1") ;
String name = request.getParameter("name") ;

String ss[] =
UploadFile2.upload(request, select, false);


String filePath = request.getParameter("fileData") ;

System.out.println(filePath) ;

System.out.println("SS:" + ss[0] +" " +ss[1]) ;
}
}

因为我现在的问题是：图片能够上传，但是无法显示在页面上，所以是路径问题，想请问，路径该怎么改，是在upload.java里面改吧？！

request.getRequestDispatcher("/pages/jididongtai.jsp").forward(request, response);

}
protected void doGet(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {

}

这段是JididongtaiServlet.java 的代码，想请问，是修改request .setAttribute("latestImages", list) ;这里面的？!初学，请指教！
