java.lang.NoSuchMethodError while running the program

I have read this thread and as it says I must have public static void main(java.lang.String[] args) my main function is like this:

public static void main(String[] args) throws FileNotFoundException, IOException, TrieException, TSException  {
        CSVReader reader=new CSVReader(new FileReader(".//Data//test1.csv"));
        String[] nextline;
        int linenumber=0;
        double[] numbers=new double[10]; 
        double[] times=new double[10];
        for(int i=0;i<=7;i++)
        {
            nextline = reader.readNext();
            numbers[i]= Double.parseDouble(nextline[0]); 
            times[i]=i;      
        }
        DiscordsAndMotifs dr= edu.hawaii.jmotif.sax.SAXFactory.series2DiscordsAndMotifs(numbers, 4, 2, 2, 2,null);// If I comment this line of code, my programm works without any error

    }

If I run my program, I get this error:

Exception in thread "main" java.lang.NoSuchMethodError: org.hackystat.utilities.logger.HackystatLogger.getLogger(Ljava/lang/String;Ljava/lang/String;) Ljava/util/logging/Logger;
  at edu.hawaii.jmotif.sax.SAXFactory.<clinit>(SAXFactory.java:51)
  at motif.discovery.MotifDiscovery.main(MotifDiscovery.java:35)`

I have required library in my project. What is the cause of this error? could you please help me to solve this problem?
