NoSuchMethodError when calling from a Schedulable
Hello,
I've made a ScheduleService that implements Schedulable and to start with I want it to be my cron-substitute. The function I call is:
public String importCSV(int limit) {
importCSV i = new importCSV();
i.importFromDB(limit);
return "OK";
}
where importCSV is found through
import saers.util.*;
importCSV.importFromDB() is defined as:
public void importFromDB(int limit)
I've set up an mbean for SchedulerService and one based on org.jboss.varia.scheduler.Scheduler. When it is called I get the exception listed under in the logs. The main problem seems to be:
Caused by: java.lang.NoSuchMethodError: saers.util.importCSV.importFromDB(I)V
but as I mentioned, it is already defined:
public void importFromDB(int limit)
so that seems correct, it takes an integer and returns void. Why am I getting a NoSuchMethodError??
Here is the complete log:
