Not able to read data from XLS

I just tried to read a data from xls
@Test(dataProvider = "getData")
public void Inplay(String event, String market, String button) {



}

@DataProvider
public Object[][] getData(){
Xls_Reader xls = new Xls_Reader("C:\\Users\\rohann\\Desktop\\Bets.xlsx");

int rows = xls.getRowCount("bet")-1;
int cols = xls.getColumnCount("bet");

Object data[][] = new Object[rows-1][cols];

for(int rNum=1; rNum<=rows; rNum++){
for(int cNum =0; cNum<cols; cNum++){
data[rNum-2][cNum]= xls.getCellData("Bets", cNum, rNum);
}

}
return data;

}

}


Getting below message without any error. Kindly look into this and please let me know
