Multiple file upload using execandwait interceptor in struts2

Question

I'm trying to upload multiple files using the ExecuteAndWait Interceptor. I've done the file uploading part that works fine, but when I use execAndwait, I got the following error

java.io.FileNotFoundException: C:\Users\hp\AppData\Roaming\NetBeans\8.0.2\config\GF_4.1\domain1\generated\jsp\FileUpload\upload_454f573a_3a8d_4e15_ba96_aa9cb6f4486f_00000002.tmp (The system cannot find the file specified)

struts.xml

Note: I've found that my code is accepting only one file upload either file or image.

Your image upload code is totally avoiding the Struts2 conventions. In Struts2 it is a lot **easier** to upload multiple files. [Refer to this answer for a complete example](http://stackoverflow.com/a/17212916/1654265). When you've made it working in the right way, try adding the execAndWait. — Andrea Ligios, Nov 04 '15 at 09:19
@Andrea- i already mention that i dont have any issue in uploading multiple file except implementing execandwait — sufiyan ali, Nov 04 '15 at 10:56
You mentioned it, but I'm telling you that you are doing it in a very weird, wrong and unproductive way. If you don't change it now, you will use this way for your next projects too, and coworkers looking your code won't be able to work on it immediately, nor efficiently. Just use it *right*, no matter if it *works*. Follow best practices (or well, at least... practices) :| — Andrea Ligios, Nov 04 '15 at 10:57
