Hello everybody. I installed Moodle 2.8 on Xampp 5.6.8 on a PC running Windows 7 SP1 x64. I installed the plugin ejsapp version 2015061300 and enable tests course in moodle. When i load Java simulations (* .jar) to the platform, they run perfectly in the browser (Firefox 42) using localhost. However, when i load a simulation created with JavaScript (*.ejss), it does not display correctly, specifically, nothing is displayed except for the Moodle interface next to the button "Update EJSApp". In addition, i tested the plataform in the last version of Lampp on Linux Mint 15 and also in Wamp on Windows 7 SP1 x64 and the same problem appears.  Curiously, using the last version of the plugin EJSApp, doesn't let me upload any simulation because an error writing the database.  Please help.

 Regards.
