structures:

• Standard Java Plugin
• Build as a standard Java JAR
• Plugin classes should place in a package name start 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 thus prevents library version conflict with base libraries or other plugins
• More difficult to develop and test due to OSGi configuration and isolation
