"How do I install Extensions for RapidMiner Server"

To install an Extension, follow these steps:

  1. Identify the Extension folder of RapidMiner Server. If you are unsure, log into the Web interface and go to System settings. Locate the property com.rapidanalytics.plugindir. If it is not there, add it and assign an arbitrary folder on the server. Normally this should be the plugins folder inside your RapidMiner Server installation directory.

  2. Obtain the Extension. Extensions can be downloaded from the Marketplace or any other source and have the file extension .jar. Make sure to use the same version as your RapidMiner Studio installation. You can also copy the extensions out of your RapidMiner Studio installation. When installed locally for the current user (which is the default), extensions are located in the folder .RapidMiner/managed of your user's home folder.

  3. Copy the Extension to the specified folder.

  4. Restart RapidMiner Server.

  5. Verify that the Extension was loaded correctly by going to Operators & Extensions in the RapidMiner Server Web interface.

    I have my rapidminer_server folder in windows machine on path "D:\Rapidminner_server" and created a folder plugins ("D:\Rapidminner_server\plugins") to store extensions. In Rapidminer server "com.rapidanalytics.plugindir" is empty so i set path as above but it is still not loading extension to the server. 

    Any help will be appriciated :)

    I have the same problem , but more weird .

    When i went to server settings there was a path for com.rapidanalytics.plugindir but when i search it show me a 'There is no such path ' message . I search a little bit and i find that the plugins folder was into a folder like this 'deployment5453132' and inside him there was a javascript file :'jquery.desaturate' . So i paste the extension jar file into these file and i re-start the server . What i found out is that the folder that i paste the extension was deleted and the folder ''deployment5453132'  was replaced with another 'deployment444445' -noticed that the numbers have changed -and into the plugin folder there was only the javascript file .

    Where should i paste these extensions to work the installation ?
