Open Source Physics
This plugin lets you download any Easy Java (and Javascript) Simulations (EJS) application stored in the OSP-Compadre library (http://www.compadre.org/osp) directly from your Moodle. This digital library won the Science Prize for Online Resources in Education, given by the Science magazine, in 2011, and it offers more than 500 ready-to-use simulations about Physics and Mathematics.
When used in combination with the EJSApp plugin, you will be able not only to access, search and download these applications but also to add them automatically to your Moodle courses as activities.
Simulations can be downloaded either as Java applets or in Javascript format (which can be run in mobile devices).

I am having the below error , would you please advise
Exception - Argument 1 passed to file_get_all_files_in_draftarea() must be of the type integer, null given, called in [dirroot]/lib/form/filemanager.php on line 336
Thank you for your work.
Of the EJSApp dependency it is stated: "This plugin lets you add any Javascript or Java application created with Easy Java/Javascript Simulations (EjsS) to your Moodle course."
The "Java application" part worries me - I don't want java programs to run on Moodle. If I use this OSP plugin will EJSApp run Java or Javascript?
Best wishes
EJS Java applets support was dropped a while ago in EJSApp, actually. I just forgot to delete some references to it in the readme and a few more places, but they don't really work with EJSApp anymore.
Best.
