Some Issues in POI-HSSF -[ Java API To Access Microsoft Excel Format Files ]

hi Experts,
Has Anybody used HSSF of the POI Project's [Provided by apache.org] , I got the binaries from the site

http://jakarta.apache.org/poi/hssf/

HSSF is the POI Project's pure Java implementation of the Excel '97(-2002) file format. HSSF provides a way to read spreadsheets create, modify, read and write XLS spreadsheets.

With that i am able to create Simple Excel Files thru Java. But i dont know how to set the Sheet Properties.
That is the Excel that i am creating is unformatted. I deally i need to set these properties in my excel Files

1) Wrap Text to Cell Width
2) Set the COlumn Widths.. .. If anyone has previously solved the same problems can y ou please update me on the same..

Thanx
NewBieWebProgrammer..

Column widths are set for all columns (of course) and the text wrap is set in the style that is applied to cells. A note of caution on using the styles, I found it to best to create some global styles for reuse since the more styles you create the larger the file will be, so reuse your styles.

HSSFSheet sheet1 = wb.createSheet("Test Results");
                  sheet1.setColumnWidth((short)0, (short)2300);
                  sheet1.setColumnWidth((short)1, (short)50);
                  sheet1.setColumnWidth((short)2, (short)9500);
                  sheet1.setColumnWidth((short)3, (short)100);
                  sheet1.setColumnWidth((short)4, (short)2300);

HSSFPrintSetup printSet = sheet1.getPrintSetup();
                  printSet.setPaperSize(HSSFPrintSetup.A4_PAPERSIZE);
                  printSet.setLandscape(true);
                  printSet.setFitWidth((short)1);
                  printSet.setFitHeight((short)0);
                  sheet1.setFitToPage(true);
                  sheet1.setHorizontallyCenter(true);
                  HSSFHeader header = sheet1.getHeader();
                  header.setLeft(HSSFHeader.file()+" Automated Test Summary");
                  header.setRight(HSSFHeader.date()+" "+HSSFHeader.time());
                  HSSFFooter footer = sheet1.getFooter();
                  footer.setRight( "Page " + HSSFFooter.page() + " of " + HSSFFooter.numPages() );
                  wb.setRepeatingRowsAndColumns(0, 0,9,0,1);
                  sheet1.setDisplayGridlines(false);
                  HSSFRow bTitle = sheet1.createRow((short)0);
                  HSSFCell cTcell = bTitle.createCell((short)0);
                  cTcell.setCellValue("Automated Test Summary");
                  HSSFCellStyle st1 = WorkbookStyles.createStyle(wb, Status.NORMAL);
                  st1.setBorderBottom(HSSFCellStyle.BORDER_NONE);
                  st1.setBorderLeft(HSSFCellStyle.BORDER_NONE);
                  st1.setBorderRight(HSSFCellStyle.BORDER_NONE);
                  st1.setBorderTop(HSSFCellStyle.BORDER_NONE);
                  st1.setAlignment(HSSFCellStyle.ALIGN_CENTER);
                  st1.setFillForegroundColor(HSSFColor.LIGHT_YELLOW.index);
                  st1.setFillBackgroundColor(HSSFColor.LIGHT_YELLOW.index);
st1.setWrapText(true);

cTcell.setCellStyle(st1);

I would say to go through the documentation and examples. It is a bit different than javadocs but it does show how.

hi Experts,
i used the setColumnWidth::HSSFSheet function to set the column Widths.. But
If i do so i am not able to write into those cells using row.createCell() Function.. But if i dont set the column widths i am able to write.. {by the Term "i am not able to write.." i mean = The text that i write does not appear in the Excel file..} Here is my complete SOuce code..

public void excelTester() {

String[][] Data={{"Row1: Column 1","Row 1: Column 2 "},{"Row2 : Column1","Row 2: COlumn 2"}};

int rowOffset=3; // leave the first first 3 rows blank and start from the 4th one..
int columnOffset=1; // leave the first column blank and start from the next one..
int i=0,j=0;

HSSFWorkbook wb = new HSSFWorkbook();
HSSFSheet sheet = wb.createSheet("new sheet");
sheet.setColumnWidth((short)1,(short)20); // Setting the width for column 1 as 20 as it going to hold a big string

for(i=0;i<=Data.length-1;i++){

     // Create a Row Here.
     HSSFRow row = sheet.createRow(rowOffset++);

      for(j=0;j<=Data[i].length-1;j++){
       row.createCell((short)(columnOffset+j)).setCellValue(Data[i][j]);


}


}

// Write the output to a file
FileOutputStream fileOut = new FileOutputStream("workbook.xls");
wb.write(fileOut);
fileOut.close();

}

FOr the above program when i run and open workbook.xls i get only the items in COLUMN displayed that is

<blank> Row 1: Column 2
<blank> Row 2: Column 2

The column 1 items are missing.. HOw do i overcome this problem..

NewBieProgrammer..

HSSFSheet sheet1 = wb.createSheet("Test Results");
sheet1.setColumnWidth((short)0, (short)2300);

              row.createCell((short)(columnOffset+j)).setCellValue(Data[i][j]);
