The free and open-source JAddin framework acts as a thin and easy to use layer between the HCL Domino RunJava task and your Java application code. It helps you to create Java server tasks by freeing you to learn all the HCL Domino add-in specifics, such as message queue handling, thread creation, communication with the console, resource cleanup, etc. It is written entirely in Java to support all HCL Domino versions and platforms (HCL Domino 9.0.1 FP8 and above).
Code Example
public class HelloWorld extends JAddinThread {
// Declarations
boolean threadRunning = true;
// This is the main entry point. When this method returns, the add-in terminates.
public void addinStart() {
logMessage("Started with parameters " + getAddinParameters());
try {
logMessage("Running on " + dbGetSession().getNotesVersion());
} catch (Exception e) {
logMessage("Unable to get Domino version: " + e.getMessage());
}
// Main add-in loop
while (threadRunning) {
logMessage("User code is executing...");
waitMilliSeconds(5000L);
}
logMessage("Terminated");
}
// This method is called by the JAddin framework when the command 'Quit' or 'Exit' is entered or during
// Domino server shutdown. Here you must signal the addinStart() method to terminate itself and to perform any cleanup.
public void addinStop() {
logMessage("Termination in progress");
// Signal addinStart method to terminate thread
threadRunning = false;
}
// This method is called by the JAddin framework for any console command entered.
@Override
public void addinCommand(String command) {
logMessage("You have entered the command " + command);
}
}
