The EJSApp Set of Plugins

EJSApp are a set of plugins for Moodle that let you:

  • To deploy applications written in Easy Java/Javascript Simulations (EjsS). Sisit the gitlab project of EjsS to get the latest version.
  • To control user access to the deployed EjsS applications and distinguish between virtual labs (or simulations) and remote labs based on Java and/or Javascript.
  • To personalize the simulations created with EjsS for each of your students.
  • To backup and restore thanks to Moodle course backups.
  • To use cloud storage for any data, image or state file created by the EjsS application.
  • To create sessions for synchronous collaborative working with the Java applets created with Easy Java/Javascript Simulations.
  • To manage and control the access to EjsS remote laboratories by means of a booking system that gets integrated into Moodle.

EJSApp Activity

The EJSApp activity plugin allows users to embedd Easy Java/Javascript Simulations (EJS) applications (such as simulations, virtual and remote laboratories) into a Moodle course. This plugin works with version 2.0 or higher of Moodle.

EJSApp plugin can be downloaded from Moodle Plugins Directory and from Github.

As with any customization, it is recommended that you have a good backup of your Moodle site before attempting to install contributed code. While those contributing code make every effort to provide the best code that they can, using contributed code nevertheless entails a certain degree of risk as contributed code is not as carefully reviewed and/or tested as the Moodle core code.

EJSApp is useful for adding simulations or remote laboratories into your Moodle courses, which is of especial interest for those of scientific or technical nature. More information about EjsS and EJSApp can be obtained at http://www.um.es/fem/EjsWiki/Main/UsingEJSWithMoodle.

Installation

If you download this plugin from github, you will need to change the folder's name to ejsapp. If you download it from Moodle.org, then you are fine.

This is a module plugin for Moodle so you should place the ejsapp folder in your /mod folder, inside your Moodle installation directory.

This module enhances its functionality when used along with the ejsappbooking module and/or the ejsapp_file_browser, the remlab_manager, the ejsapp_collab_session blocks and the osp repository plugin. You can find and download them at https://moodle.org/plugins/browse.php?list=set&id=27, in the plugins section in the Moodle.org webpage or at https://github.com/UNEDLabs.

  • Settings - During the previous step you will come across the setting configuration page for the EJSApp plugin. Default values might be valid for you. However, read the description of each parameter there and change any value you want. The README.txt file that comes along with the EJSApp plugin has even more information about these parameters.

Configuration

When installing ejsapp for the first time, you will need to set six variables:

  • certificate_path: This variable defines the absolute path to the trust certificate file, if you have one for signing your Java applets.
  • certificate_password: This variable must contain the password of the trust certificate.
  • "certificate_alias": This variable stores the alias given to your trust certificate.

If you are not sure what values you should be setting for these parameters, use the ones by default.

Languages

The EJSApp activity plugin is available in:

  • English (en_utf8)
  • Spanish (es_utf8)

If you would like to supply translations for other languages, please create an issue in the tracker and attach a zip file of the language files.

Related Plugins

The EJSApp activity plugin works autonomously and does not require any other plugin to be installed in your Moodle site. However, there are three more plugins (the EJSAppBooking activity plugin and the EJSAppFileBrowser and the EJSAppCollabSession block plugins) that add new features to the system and might enhance the use of your EjsS applications embedded into Moodle.

These additional plugins can also be downloaded from the EJSApp Set Webpage at Moodle Plugins Directory and from Github.
