UpdateResult_DataSet is giving error while running

when I run the below code in eclipse:
package test;

import com.qtpselenium.util.Xls_Reader;

public class UpdateResult_DataSet {

public static void main(String[] args) {

Xls_Reader x = new Xls_Reader(System.getProperty("user.dir")+"\\src\\com\\qtpselenium\\xls\\B suite.xlsx");
reportDataSetResult(x,"TestCase_B1",3,"Pass");


}

// update results for a particular data set
public static void reportDataSetResult(Xls_Reader xls, String testCaseName, int rowNum,String result){
xls.setCellData("testCaseName", "Results", rowNum, result);
}
}
I get this error :
