This plugin is required by the EJSApp Booking System module (, which allows booking time slots in order to work with the remote labs.

The Java applets or the Javascript applications should have been created with version 5.1 (build 20150613 or later) of EjsS to work properly.

    Thanks Luis for sharing the block with the community. I am afraid I cannot approve it now due to serious issues detected in the code. Please see you issues tracker for details. All the issues #1 (direct access to the superglobal $_SESSION), #2 (tables names and installation) and #3 (lack of access permission control) block the approval now so I am marking this plugin as requiring more work. Thanks for your understanding and the patience with the review and approval process.

    Thanks Luis for providing the fixed version quickly.

    I am a bit worried about the dependency on the EJSApp activity module. This block declares minimal required version of mod_ejsapp as 2016080400. However, that version is only available at github and was not officially released here in the plugins directory. As a consequence, the in-built plugin installer in moodle can't fulfil the dependency and it fails to install this block. As you are one of the maintainers of EJSApp module, you probably want to release that new version first.

    While looking at the code again, I noticed missing CSRF protection in your action links. I reported this security issue into your tracker.

    I'll be happy to approve this block once these issues are fixed.

    p.s. It is discouraged to make other already approved plugins depending on a plugin not yet available in the plugins directory as you did with the EJSApp Booking System. You can put users of your plugin into troubles when they are upgrading their sites. Thanks for understanding.

    Dear David,

    Thank you so much for your comments and help for improving the plugin. And thank you for creating/updating the wiki page with the information about CSRF protection (I noticed it was last edited on August 18th). It was very, very helpful!

    You are right about the dependency of the EJSApp activity module. I just uploaded a newer version (the one required now by the Remlab Manager block). I have also uploaded a new version of the Remlab Manager plugin with the changes that solve the two issues you noticed.

    Again, thanks a lot for everything. I think you are doing an outstanding job with Moodle's plugins section and for the plugins community.
