As there is no sound in this video, we will talk about it in the next lesson, "Struts2 database Access".

Note: Sorry, I do not know why in this recording process is not sound, I am sorry, this section is focused on a null pointer exception, because the FileUpload this interceptor to be placed before the other interceptors do not have problems, the material to the code is problematic.

Error:

<interceptor-ref name= "Basicstack" >       <interceptor-ref name= "FileUpload" >           <param name= " Allowedtypes ">image/jpeg,image/gif</param>       </interceptor-ref>

That's right:

       <interceptor-ref name= "FileUpload" >           <param name= "Allowedtypes" >image/jpeg,image/gif</param >       </interceptor-ref><interceptor-ref name= "Basicstack" >
