jbuilder中关于类的import问题？

[zrwfx]

我有一段代码
package BaseData;
import javax.servlet.*;
import javax.servlet.http.*;
import java.io.*;
import java.util.*;
import Common.*;
import java.sql.*;
import com.borland.jb.io.EncodedOutputStream;

public class AddArea extends HttpServlet
{

//Initialize global variables
public void init(ServletConfig config) throws ServletException
{
super.init(config);
}

//Process the HTTP Get request
public void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException
{
if(!ManageMember.AllMember.canRight(request,203,response)){
response.sendRedirect("/admin/error.jsp");
return;
}
response.setContentType("text/html");
EncodedOutputStream out = new EncodedOutputStream(response.getOutputStream());
PageFrame.printHead(out,"填加地区","admin");
out.writeln("<script>");
out.writeln("function check(){");
out.writeln("if(document.form1.newname.value==''){");
out.writeln("alert('名称不能为空！');");
out.writeln("document.form1.newname.focus();");
out.writeln("return false;");
out.writeln("};");
out.writeln("return true;");
out.writeln("}</script>");
out.writeln("<form name='form1' method='post' action='/servlet/BaseData.AddArea' onsubmit=\"return check()\">");
out.writeln(" <br><br><table width='40%' border='1' align=center>");
out.writeln(" <tr>");
out.writeln(" <td width='32%' height=40 align=right>名 称：</td>");
out.writeln(" <td width='68%'>");
out.writeln(" <input type='text' name='newname'>");
out.writeln(" <input type='hidden' name='id' value='"+request.getParameter("id")+"'>");
out.writeln(" <input type='hidden' name='level' value='"+request.getParameter("level")+"'>");
out.writeln(" </td>");
out.writeln(" </tr>");
out.writeln(" <tr>");
out.writeln(" <td colspan='2' align=center height=50>");
out.writeln(" <input type='submit' name='Submit' value='添　加'>");
out.writeln(" </td>");
out.writeln(" </tr>");
out.writeln(" </table> <br><br>");
out.writeln("</form>");
PageFrame.printTail(out,"admin");
out.close ();
}

//Process the HTTP Post request
public void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException
{
if(!ManageMember.AllMember.canRight(request,203,response)){
response.sendRedirect("/admin/error.jsp");
return;
}
int id=0;
String newname="";
int level=0;
if(request.getParameter("id")!=null)
id=GlbFunction.getParameterInt(request,"id");
if(request.getParameter("newname")!=null)
newname=GlbFunction.getParameter(request,"newname");
if(request.getParameter("level")!=null)
level=GlbFunction.getParameterInt(request,"level");
try{
String sql="insert st_Area(sAreaName,ilevel,iparent) values('"+newname+"',"+level+","+id+")";
ConnPool pool=ConnPool.getInstance ();
Connection conn=pool.getConnection ();
Statement stm=conn.createStatement();
stm.executeUpdate(sql);
stm.close();
pool.Release (conn);
BDCommon.CreateArea1();
response.sendRedirect("/servlet/BaseData.ManageArea?id="+id);
}catch(Exception e){
ConnPool.log(e.getMessage ()+"addArea");
}
}

//Get Servlet information
public String getServletInfo()
{
return "BaseDate.ModifyContent Information";
}
}
但在编译时出现
"AddArea.java": Error #: 704 : cannot access directory javax\servlet at line 2, column 1
"AddArea.java": Error #: 704 : cannot access directory javax\servlet\http at line 3, column 1
问题，javax.servlet.*不是jbulider自带的类库吗？怎么找不见？急！！！
紧急求助！！！再线等待！！！

找不到就设置一下ClassPath嘛。

自带的也要在工程中加入啊

工程属性中加上它

classpath 中增加 servlet.jar 的引用!
