apache-poi

Hoping someone might have some experience with this. I'm using Apache POI 3.8b4 to output a table in Word 2007 format. When I do something similar to the following: XWPFTableRow row = table.getRow(0); String text = "A\nB\nC\nD"; row.getCell(i).setText(text); all of my line breaks are ignored in the output in the table cell looks like A B C D Does anyone have any idea how to get it to properly display as A B C D Edit: The solution was the following: XWPFParagraph para = row.getCell(i).getParagraphs().get(0); for(String text : myStrings){ XWPFRun run = para.createRun(); run.setText(text.trim());

I want to export data to excel using Apache poi . Now the problem that I am facing is that I am unable to merge rows and align them in the center. Code for export data is: List<LinkedHashMap<String,Object>> lstReportHeader = null; HSSFWorkbook wb = new HSSFWorkbook(); HSSFSheet sheet = wb.createSheet(); //Set Header Font HSSFFont headerFont = wb.createFont(); headerFont.setBoldweight(headerFont.BOLDWEIGHT_BOLD); headerFont.setFontHeightInPoints((short) 12); //Set Header Style CellStyle headerStyle = wb.createCellStyle(); headerStyle.setFillBackgroundColor(IndexedColors.BLACK.getIndex());

I need to display a value in an excel cell formatted like a percentage, e.g. like 12.3% . By default the value is displayed as Text, but I need to display it as a number. What is the appropriate method to achieve this? You need to: Set your data as number (floating-point), not as text. Specify cell format as percentage. Something like: cell.setCellValue(0.123); // set value as number CellStyle style = workbook.createCellStyle(); style.setDataFormat(workbook.createDataFormat().getFormat("0.000%")); cell.setCellStyle(style); Take a look at user defined formats section of POI quick guide for more

I wrote code which should create an Excel file (xlsx or xls) and set a custom background color to cell. When creating the xls file the background color works fine, but in case of xlsx the background color is not set to the right color. What is wrong in my code? public class PoiWriteExcelFile { static Workbook workbook; static Sheet worksheet; public static void main(String[] args) { try { String type = "xlsx"; //xls FileOutputStream fileOut = new FileOutputStream("D:\\poi-test." + type); switch (type) { case "xls": workbook = new HSSFWorkbook(); break; case "xlsx": workbook = new XSSFWorkbook(

I have been trying to add a picture to a new docx file using Java POI to the header. 1) I have added a header, and added a text to it (using XWPFHeaderFooterPolicy). 2) I have create an image (using CustomXWPFDocument). 3) But I could not insert the image inside the header area. I have tried to do so through adding the picture into the same paragraph of the header, but it did not work. Here is the function that should add the picture to the header. It takes a CustomXWPFDocument object that has been already created: private void addLogo(CustomXWPFDocument doc) throws InvalidFormatException,

I find this website ( http://poi4xpages.openntf.org/ ) for install POI 4 in domino designer.

Someone told me that Tika's XWPFWordExtractorDecorator class is used to convert docx into html. But I am not sure how to use this class to get the HTML from docx. Any other library for doing the same job is also appreciated/ You shouldn't use it directly Instead, call Tika in the usual way, and it'll call the appropriate code for you If you want XHTML from parsing a file, the code looks something like // Either of these will work, the latter is recommended //InputStream input = new FileInputStream("test.docx"); InputStream input = TikaInputStream.get(new File("test.docx")); // AutoDetect is
