Well there is an easier way that I use in cases that no standards need
to be followed. What I do is take a normal service and simply execute
the business code via a thread, and return immediately. A brief
example where execute() will not block, ie will return immediately and
leave the code executing in the background:
private static final ThreadFactory factory = new
MyThreadFactory(new MyExceptionHandler());
private static final ExecutorService executorService =
Executors.newFixedThreadPool(10, factory);
MyBusinessClass myBusinessClass;
public OMElement doAsyncJob(OMElement element) throws XMLStreamException {
...
execute();
...
}
public void execute(final Long deptID, final String message, final
Boolean forceRunExecute, final String uuid) throws Exception {
// execute asynchronously and return immediately
executorService.execute(new Runnable() {
public void run() {
try {
myBusinessClass.runJob();
} catch (Exception ex) {
logger.error(ex.getMessage(), ex);
}
}
});
}
