2. Cause of error

<action name= "Download" class= "com.you.mail.action.DownloadAction" ><result name= "Success" type= "Stream" ><param name= "ContentType" >application/vnd.ms-powerpoint</param><param name= " Contentdisposition ">filename=" ceshi.ppt "</param><param name=" InputName ">downloadFile</param ></result></action>

3, the solution of the method

In the download action, the configuration parameters are not downloadfile, resulting in an error; View action, parameter named filename, change downloadfile to filename

Can not find a java.io.InputStream with the name [DownloadFile] in the invocation stack.
