Plugins everywhere! Joget Workflow v3 provides an improved plugin architecture that supports both normal Java and dynamic OSGI plugins.

...
Due to the major changes in the app structure in v3 compared to v2, it will be highly unlikely that v2 plugins will be directly compatible in v3.
So existing plugins written for v2 will need to be rebuilt using the v3 structure and Java API.
Development Approach
The method of developing a v3 Joget plugin remains the same as described in Extending Functionality - Developing Plugins. However, there is an additional feature in that you now have an the option of using an additional feature: standard Java classes which . Standard Java classes are read directly from the classpath.
The following table highlights the different approaches:
Dynamic OSGI Plugin | Standard Java Plugin |
|---|---|
Build as an OSGI JAR bundle | Build as a standard Java JAR |
Deploy JAR using the Manage Plugins in the Web Console | Make JAR available in the Java classpath (e.g., place it under WEB-INF/lib) |
Supports dynamic loading/unloading/reloading without restarting | Requires restarting the JVM for deployment or changes |
Runs in isolated mode, thus prevents , preventing library version conflict with base libraries or other plugins | May cause library version conflicts with base libraries or other plugins |
More difficult to develop and test due to OSGI configuration and isolation | Easier to develop and test using normal Java classes and libraries |
