求助，servlet怎么不能获得从jsp传来的数据啊！！
在jsp中的代码：
<form   action= "../uploadImg "   method= "post "   enctype= "multipart/form-data "   name= "form1 ">
<table>
<tr>
<td   align= "left "> Name: </td>
<td   align= "left "> <input   type= "text "   name= "picName "> </td>
</tr>
<tr>
<td   align= "left "> Path: </td>
<td   align= "left "> <input   type= "file "   name= "picPath "> </td>
</tr>
<tr>
<td   align= "left "> Describe: </td>
<td   align= "left "> <textarea   rows= "5 "   cols= "30 "   name= "picDescribe "   > </textarea> </td>
</tr>
<tr>
<td   align= "center "> </td>
<td   align= "center ">
<input   type= "submit "   name= "bSubmit "   id= "bSubmit ">
<input   type= "reset "   name= "bReset "   id= "bReset ">
</td>
</tr>
</table>
</form>
在servlet中的代码：
protected   void   doPost(HttpServletRequest   req,   HttpServletResponse   res)   throws   ServletException,   IOException   {
//   TODO   Auto-generated   method   stub
String   picName = req.getParameter( "picName ");
System.out.println(picName);
String   picPath = req.getParameter( "picPath ");
System.out.println(picPath);
String   picDescribe = req.getParameter( "picDescribe ");

}    
结果打印出来的值都是null
为什么啊～～～，改了好长时间都没成功！！

------解决方案--------------------
lz的混合表单上传在Servlet中这样取值当然为空了。
------解决方案--------------------
web.xml配置好了没
------解决方案--------------------
把enctype= "multipart/form-data "删除！
如果要上传文件不能从request中获得值，
如果用SmartUpload组件上传，则取值方法为“SmartUpload.getRequest().getParameter( "aa ");”
