webwork 的上传文件功能

jsp页面代码：

<form action="/ww/upload.action" name="myform2" enctype="multipart/form-data" method="POST">
       <div align="center" >
	   <br>
	   <br>
	   <br>
	   <br>
	   <br>
       <div  class="upload" style="text-align:left;" style="width:260px" >
       <input type="text" name="title"/>文章标题<br>
       <input type="text" name="titleFile">文件名称<br>
       <INPUT type="file" name="file" ><br>
       
       </div>
	   <br>
	   <br>
	   <a href="#" onClick="tijiao();">上传</a>
       </div>
       </form>

xwork.xml配置：

<action name = "upload" class = "com.iyouhe.test.UploadAction" > 
        <interceptor-ref name="fileUploadStack"></interceptor-ref>
        
            <result name = "success" type = "dispatcher" >index.jsp</result > 

              <interceptor-ref name = "params" /> 
             
      </action > 

action处理：
