public String doLongJobPolling(String jobName) throws Exception {
LOGGER.debug("Executing.");
SoaCookbookService svc = new SoaCookbookService();
SoaCookbook port = svc.getSoaCookbookPort();
Response<DoLongJobResponse> response =
port.doLongJobAsync(jobName);
LOGGER.debug("Invoked service.");
while(!response.isDone()){
LOGGER.debug("Waiting...");
Thread.sleep(1000); //do something
}
DoLongJobResponse res = response.get();
String status = res.getJobDone();
LOGGER.debug("Status: " + status);
return status;
}
}
Once the
isDone
method returns true, the response object is available.
Running this client from a unit test using a fabricated job name of “My Batch” has this output:
Executing.
Invoked service.
