Architecture
Some background information on the framework architecture
Framework Architecture
The JAddin architecture consists of two Java classes which are distributed with your application code.

JAddin.class
The JAddin class is loaded by the HCL Domino RunJava task as the main Java thread. It executes under the control of RunJava and shares the HCL Domino Java Virtual Machine (JVM) with RunJava.
Main functions of JAddin thread:
Initialize the JAddin framework
Dynamically loads and starts the user add-in as a subclass of JAddinThread
Monitors the Java heap space
Acts on special framework commands (see command
Help!
)Supports internal debugging thru
Debug!
commandBackcalls the user methods
addInXXX()
(see below)
JAddinThread.class
This abstract class must be implemented by the user add-in class. It runs as a separate thread to minimize any delays on the normal processing of the HCL Domino server.
Initialize the runtime environment
Calls the user class thru addinStart()
Includes several methods for accessing HCL Domino objects and the server environment
AddinName.class
The user code runs within a subclass of JAddinThread and handles all application-specific processing. The framework invokes several callback methods that can or must be implemented by the user class. When the user class completes execution, the framework performs the necessary cleanup and terminates the main JAddin thread.
