我在jbuilder6中写了个Servlet

但是我在编译的时（用JBUILDER），它总是把upload的下面的确SmartUpload.class和SmartUploadException.class

删除掉！导致我的程序找不到SmartUpload类,这是怎么回事情

我是TOMCAT4。0
我的程序是这样的

package corp;

import javax.servlet.*;
import javax.servlet.http.*;
import java.io.*;
import java.util.*;
import java.sql.*;
import com.jspsmart.upload.SmartUpload;

//Initialize global variables
private ServletConfig config;
public void init(ServletConfig config) throws ServletException {
this.config = config;
}
int count=0;
SmartUpload myup = new SmartUpload();
//Process the HTTP Post request
public void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
// Variables
try{
myup.initialize(config,request,response);
myup.setAllowedFilesList("jpg,gif,bmp,png,ico");
myup.setDeniedFilesList("asp,php,jsp,exe,cfm,com,js,css,bat");
myup.setMaxFileSize(1048576);
myup.setDenyPhysicalPath(true);
myup.upload();
myup.save("/images/",myup.SAVE_VIRTUAL);

HttpSession session = request.getSession();
// String user = (String)session.getAttribute("username");

}
catch(com.jspsmart.upload.SmartUploadException e){
System.out.print(e.getMessage());

}
}
}
//Clean up resources
