I'm sure no have wrong in code i think may have relationship between jar file and HTML
For example when i run jar file and after use button reset sounds no stop but when i close EJS and close site your prof
Sounds stop so i think because jar file have like relationship between source code in EJS and jar sound that i save in _data
And jar file in your site because upload in site but about project code is all right no have any problem and run by EJS very well.
However is not problem i can post by language portages .
