Can not modify a blank spreadsheet
Summary: Can not modify a blank spreadsheet
Product: POI
Version: 2.0-dev
Platform: All
OS/Version: All
Status: NEW
Severity: Blocker
Priority: Other
Component: HSSF
AssignedTo: poi-dev@jakarta.apache.org
ReportedBy: tschafer@hotmail.com
I have tried:
jakarta-poi-1.8.0-dev-20020919.jar
jakarta-poi-1.10.0-dev-20030222.jar
poi-2.0-pre1-20030517.jar
In each case using POI to modify a blank (open Excel press save) spreadsheet
created using each of:
Excel 2000 (9.0.2720)
Excel 2002 (10.2614.2625)
resulted in a blank spreadsheet
Using other input spreadsheets of varying complexity would result in a corrupt
output spreadsheet
But generally the result spreadsheet appeared as if it had not been modified
This problem does not occur using jakarta-poi-1.5.1-final-20020615.jar
Code sample:
import java.io.FileInputStream;
import java.io.FileOutputStream;
import org.apache.poi.poifs.filesystem.POIFSFileSystem;
import org.apache.poi.hssf.usermodel.HSSFWorkbook;
import org.apache.poi.hssf.usermodel.HSSFSheet;
import org.apache.poi.hssf.usermodel.HSSFRow;
import org.apache.poi.hssf.usermodel.HSSFCell;
public class testPOI {
public static void main(String[] args) throws java.io.IOException,
java.io.FileNotFoundException {
// section 1
POIFSFileSystem fs = new POIFSFileSystem(new FileInputStream("blank.xls"));
HSSFWorkbook wb = new HSSFWorkbook(fs);
HSSFSheet sheet = wb.getSheetAt(0);
// section 2
//HSSFWorkbook wb = new HSSFWorkbook();
//HSSFSheet sheet = wb.createSheet("new sheet");
HSSFRow row = sheet.getRow(2);
if(row == null)
row = sheet.createRow((short)2);
HSSFCell cell = row.getCell((short)3);
if(cell == null)
cell = row.createCell((short)3);
cell.setCellType(HSSFCell.CELL_TYPE_STRING);
cell.setCellValue("a test");
FileOutputStream fileOut = new FileOutputStream("output.xls");
wb.write(fileOut);
fileOut.close();
}
}
