I need to create multiple excel sheet in Java using jExcel API if one sheet is full (65536 rows). Suppose if one sheet got full then in the next sheet it should start writing automatically from where it left off in the first sheet. I am just stuck on putting the logic to create it dynamically whenever one sheet is full. Below is the code that I have done so far.
public void write() throws IOException, WriteException {
File file = new File(inputFile);
WorkbookSettings wbSettings = new WorkbookSettings();
wbSettings.setLocale(new Locale("en", "EN"));
WritableWorkbook workbook = Workbook.createWorkbook(file, wbSettings);
writingToExcel(workbook);
}
//Logic to create sheet dyanmically if one is full should be done here I guess?
private void writingToExcel(WritableWorkbook workbook) {
workbook.createSheet("Report", 0);
WritableSheet excelSheet = workbook.getSheet(0);
try {
createLabel(excelSheet);
createContent(excelSheet);
} catch (WriteException e) {
e.printStackTrace();
} finally {
try {
workbook.write();
workbook.close();
} catch (IOException e) {
e.printStackTrace();
} catch (WriteException e) {
e.printStackTrace();
}
}
}
private void createLabel(WritableSheet sheet) throws WriteException {
WritableFont times10pt = new WritableFont(WritableFont.TIMES, 10);
times = new WritableCellFormat(times10pt);
times.setWrap(true);
WritableFont times10ptBoldUnderline = new WritableFont(WritableFont.TIMES, 10, WritableFont.BOLD, false,UnderlineStyle.SINGLE);
timesBoldUnderline = new WritableCellFormat(times10ptBoldUnderline);
timesBoldUnderline.setWrap(true);
CellView cv = new CellView();
cv.setFormat(times);
cv.setFormat(timesBoldUnderline);
cv.setAutosize(true);
// Write a few headers
addCaption(sheet, 0, 0, "Header 1");
addCaption(sheet, 1, 0, "This is another header");
}
private void createContent(WritableSheet sheet) throws WriteException,
RowsExceededException {
for (int i = 1; i < 70000; i++) {
addNumber(sheet, 0, i, i + 10);
addNumber(sheet, 1, i, i * i);
}
}
private void addCaption(WritableSheet sheet, int column, int row, String s)
throws RowsExceededException, WriteException {
Label label;
label = new Label(column, row, s, timesBoldUnderline);
sheet.addCell(label);
}
private void addNumber(WritableSheet sheet, int column, int row,
Integer integer) throws WriteException, RowsExceededException {
Number number;
number = new Number(column, row, integer, times);
sheet.addCell(number);
}
I am not sure how to add that logic here in my code.
Any suggestions will be of great help?
Or in any case, can anyone provide me a simple example in which if one sheet is full, it should start writing automatically into different sheet (Second sheet)?
I made changes to the following 2 methods:-
private void writingToExcel(WritableWorkbook workbook) {
try {
// don't create a sheet now, instead, pass it in the workbook
createContent(workbook);
}
catch (WriteException e) {
e.printStackTrace();
}
finally {
try {
workbook.write();
workbook.close();
}
catch (IOException e) {
e.printStackTrace();
}
catch (WriteException e) {
e.printStackTrace();
}
}
}
// instead of taking a sheet, take a workbook because we cannot ensure if the sheet can fit all the content at this point
private void createContent(WritableWorkbook workbook) throws WriteException {
int excelSheetIndex = 0;
int rowIndex = 0;
WritableSheet excelSheet = null;
for (int i = 1; i < 70000; i++) {
// if the sheet has hit the cap, then create a new sheet, new label row and reset the row count
if (excelSheet == null || excelSheet.getRows() == 65536) {
excelSheet = workbook.createSheet("Report " + excelSheetIndex, excelSheetIndex++);
createLabel(excelSheet);
rowIndex = 0;
}
// instead of using i for row, use rowIndex
addNumber(excelSheet, 0, rowIndex, i + 10);
addNumber(excelSheet, 1, rowIndex, i * i);
// increment the sheet row
rowIndex++;
}

I need to check if the worksheet exists.
If it exists, you must type in the next existing row and do not create a new worksheet.
You are currently deleting the current spreadsheet and I always get only 1 line written in the spreadsheet.
How do I solve this?

I'm here to ask for help in my java project in Netbeans.
I'm using Apache POI to import/export excel data. To make you understand what is the problem in my application, I'm showing you a print of the debug.
In the print, you can see 2 sheets. The first header "aiai" and the data from that sheet.
My problem is: How do i insert the data from "aiai2" which is the second sheet from my excel file, in its proper place, below the header "aiai2"
On other words, I want to separate the sheets vertically.
Below, I will show my code:
Workbook wb;
public String Importar(File archivo, JTable tablaD) {
String answer = "Unable to import";
DefaultTableModel modeloT = new DefaultTableModel();
tablaD.setModel(modeloT);
tablaD.getModel();
tablaD.setAutoResizeMode(JTable.AUTO_RESIZE_OFF);
try {
wb = WorkbookFactory.create(new FileInputStream(archivo));
int nsheets = wb.getNumberOfSheets();
for (int i = 0; i < nsheets; i++) {
Sheet sheet = wb.getSheetAt(i);
Iterator filaIterator = sheet.rowIterator();
int rownum = -1;
while (filaIterator.hasNext()) {
rownum++;
Row fila = (Row) filaIterator.next();
/*if (i > 0) {//se o nr da ficha atual for maior que 0, começa a escrever as linhas apartir da row 0 da tabela
modeloT.moveRow(modeloT.getRowCount() -1, modeloT.getRowCount() - 1, 0);
}*/
Iterator columnaIterator = fila.cellIterator();
Object[] listaColumna = new Object[1000];
int columnnum = -1;
while (columnaIterator.hasNext()) {
columnnum++;
Cell celda = (Cell) columnaIterator.next();
if (rownum == 0) {
modeloT.addColumn(celda.getStringCellValue());
} else {
if (celda != null) {
switch (celda.getCellType()) {
case Cell.CELL_TYPE_NUMERIC:
listaColumna[columnnum] = (int) Math.round(celda.getNumericCellValue());
break;
case Cell.CELL_TYPE_STRING:
listaColumna[columnnum] = celda.getStringCellValue();
break;
case Cell.CELL_TYPE_BOOLEAN:
listaColumna[columnnum] = celda.getBooleanCellValue();
break;
default:
listaColumna[columnnum] = celda.getDateCellValue();
break;
}//end switch case
System.out.println("Column:" + columnnum + " Row:" + rownum + " value:" + celda + ".");
}
}
}//end while column Iterator
if (rownum != 0) {
modeloT.addRow(listaColumna);
}
}//end while row iterator
}//end for
answer = "Imported with success";
} catch (IOException | InvalidFormatException | EncryptedDocumentException e) {
System.err.println(e.getMessage());
}
return answer;
}
public String Exportar(File archivo, JTable tablaD) {
String answer = "Unable to export";
int numFila = tablaD.getRowCount(), numColumna = tablaD.getColumnCount();
if (archivo.getName().endsWith("xls")) {

} else {

}
Sheet hoja = wb.createSheet("Default");
try {
for (int i = -1; i < numFila; i++) {
Row fila = hoja.createRow(i + 1);
for (int j = 0; j < numColumna; j++) {
Cell celda = fila.createCell(j);
if (i == -1) {
celda.setCellValue(String.valueOf(tablaD.getColumnName(j)));
} else {
celda.setCellValue(String.valueOf(tablaD.getValueAt(i, j)));
}
wb.write(new FileOutputStream(archivo));
}
}
answer = "Exported with success";
} catch (Exception e) {
System.err.println(e.getMessage());
}
return answer;
}
As I understand your question, I assume you want to create a separate table for each sheet, one below other. In that case you need to create a new table everytime you read a new sheet. If you use only one table, you will get only one header.
Try this :
Create a new method Importar that takes a new table and a Sheet parameter
public String Importar(JTable tablaD, Sheet sheet) {
String answer = "Unable to import";
DefaultTableModel modeloT = new DefaultTableModel();
tablaD.setModel(modeloT);
tablaD.getModel();
tablaD.setAutoResizeMode(JTable.AUTO_RESIZE_OFF);
try {
Iterator filaIterator = sheet.rowIterator();
int rownum = -1;
....
....
So the calling method would be :
try {
Workbook wb = WorkbookFactory.create(new FileInputStream(archivo));
int nsheets = wb.getNumberOfSheets();
for (int i = 0; i < nsheets; i++) {
//You have to make sure your JTable gets rendered.
JTable tablaD = new JTable();
Importar( tablaD, wb.getSheetAt(i) );
}
} catch ( Exception e ) {
e.printStackTrace();
}
Important point is that your new table needs to get rendered or added to frame each time before you call Importar
What I am trying to do is onTestFailure (TestNG) I am trying to write a pass/fail to a specified column. In the below code, I just wanted to do a little test to write Fail to a specified cell. But what's happening is, instead of writing a pass/fail to the specified cell, it literally overwrites the entire file and erases all of my data and I am puzzled as to why that's happening. I have looked on here and googled but cannot find the answer. Below is the following code:
#Override
public synchronized void onTestFailure(ITestResult tr){
try {
Workbook workbook = Workbook.getWorkbook(new File(testData), workbookSettings);
WritableWorkbook wb = Workbook.createWorkbook(new File(testData), workbook);
WritableSheet ws = wb.getSheet("OrderEditQA3");
Label label = new Label(5,2, "Fail");
ws.addCell(label);
wb.write();
} catch (IOException e) {
e.printStackTrace();
} catch (BiffException b){
System.out.print("Error!");
} catch (WriteException we){
System.out.print("");
}
}
Any help would be greatly appreciated.
UPDATED...

I need help extracting all the file names within a folder in Business Objects. With the code I have now I can get the name of a single file within a folder. I want to get all the file names in that folder. The variable temp is where I enter the name of the file that I want. The variable doc is where the file name is retrieved, and the variable reportname is where I store doc to write to an external spreadsheet.

If Temp is going to hold the name of a unique folder, then you can use this code. Replace the String query = line with:
IInfoObjects oParents = infoStore.query("select si_id from ci_infoobjects where si_kind = 'folder' and si_name = '" + temp + "'");
if(oParents.size()==0)
return; // folder name not found
IInfoObject oParent = (IInfoObject)oParents.get(0);
String query = "select SI_NAME, SI_ID from CI_INFOOBJECTS "
+ "where SI_KIND = 'Webi' and si_parentid = " + oParent.getID();
I don't see in the code where you're populating the temp, username, or password variables, but I assume you just left that out of the listing intentionally. Obviously they will need to be defined.
Couple of other things I noticed in your code:
You are purging the query in each report, but not saving the report afterwards.
You are storing the report's SQL in an instance variable named query, but you also have a local variable named query in the variable constructor. This could very likely cause a conflict if you need the SQL value for something.
You have an "empty catch" for SDKException. SDKExceptions can happen for all kinds of reasons, and as it is you will not know why the program failed. You should at least be printing out the exception, or just let it bubble up.
I need to add a new sheet with different methods and headers within the same workbook. I'm able to add the new sheet but how do add the separate methods and headers for the second sheet? Right now both sheets are duplicate copies. Basically How would I add different data to both sheets. Any help would be appreciated and I always accept the answers and also up vote.
