Figure 1: Joget Plugin Architecture

Standard Java Plugin

• Build as a standard Java JAR
• Plugin classes should be placed in a package name starting with “org.joget”.
• Make JAR available in the Java classpath (e.g., place it under WEB-INF/lib).
• Requires restarting the JVM for deployment or changes
• May cause library version conflicts with base libraries or other plugins
• Easier to develop and test using normal Java classes and libraries

Dynamic OSGi Plugin

• Build as an OSGi (Open Services Gateway initiative framework) JAR bundle
• Deploy JAR using the Manage Plugins in the Web Console.
• Supports dynamic loading/unloading/reloading without restarting
• Runs in isolated mode, preventing library version conflict with base libraries or other plugins
• More difficult to develop and test due to OSGi configuration and isolation
• Technology powering this structure: Apache Felix
