I am using Jakarta POI to write to excel using servlets. I am using a formula to calculate the sum: cell1.setCellFormula("SUM(A1:A2)"). But I am getting this error: Method setCellFormula(String) not found. I am also importing this package: org.apache.poi.hssf.usermodel.HSSFCell. Could you please tell me where I might be going wrong.
