If your script need to reuse for multiple times in an app or can be used by others app in future development, please consider to make your Bean Shell script as a plugin instead of copy and paste it multiple times across your app. Bean Shell script is harder to maintain in this case. Imagine that you want to make a change, you will have to update all the places that are using the same script as well. Beside that, a normal plugin implementation will have better performance than a script running by a Bean Shell interpreter.

8. Reuse existing plugins in your code to make it cleaner and easy to maintain

If partial of your script can be done by existing plugins in Joget Workflow, you can reuse the plugin in stead of writting it again. 

To reuse a plugin, you can retrieve the plugin using PluginManager, then set it properties and execute it.

Example: 

1. Reuse Multi Row Binder plugin to load data
2. Reuse Email Tool to send email
