I have some troubles to export my report as XLS . The export as PDF works well. So I tried to update to the latest JasperReports and Apache POI version: JasperReports: 5.5.0 POI: 3.7 iText: 2.1.7 But I receive always following exception: java.lang.NoSuchMethodError: org.apache.poi.hssf.usermodel.HSSFWorkbook.createDataFormat()Lorg/apache/poi/hssf/usermodel/HSSFDataFormat; net.sf.jasperreports.engine.export.JRXlsExporter.openWorkbook(JRXlsExporter.java:284) net.sf.jasperreports.engine.export.JRXlsAbstractExporter.exportReportToStream(JRXlsAbstractExporter.java:927) net.sf.jasperreports.engine

I am new to apache poi, I wanted to split a excel file into multiple files based on row count. E.g data.xlsx has 15k rows, new files should be like data_1.xlsx with 5k rows,data_2.xlsx should be 5-10k and data_3.xlsx should be 10-15k. I've got you. package com.industries.seanimus; import java.io.File; import java.io.FileOutputStream; import java.io.IOException; import java.util.ArrayList; import java.util.List; import org.apache.poi.EncryptedDocumentException; import org.apache.poi.openxml4j.exceptions.InvalidFormatException; import org.apache.poi.openxml4j.opc.OPCPackage; import org.apache

I am reading a text file separated with some delimiters. Example of my text file content Avc def efg jksjd 1 2 3 5 3 4 6 0 line by line and holding it in memory using hashmap having line numbers as key of integer type and each line of text file as List object Consider, my map would store information like this Integer List 1 [Avc def efg jksjd] I am using Apache POI to write into excel. When writing into excel using Apache POI, I am following this approach, here is my code snippet HSSFWorkbook workbook = new HSSFWorkbook(); HSSFSheet sheet = workbook.createSheet("Sample sheet"); Map<Integer,

I have been searching for a while, and haven't been able to find a solution as yet. This question has been asked before on here but the OP didn't get a response and I didn't want to resurrect an old thread so decided on asking a new question. The OP thread is here . The problem I'm having is that I've got a spreadsheet which is created with data obtained from a database, however sometimes the data within cells can be quite lengthy, so wanted POI to autosize to save the user having to do it, but because I'm setting autofilter before calling autosize, it's not quite working. I'm using Apache POI

I have a need to replicate a framework I built ij Java using the Apache POI api to read data from MS Excel. I have no idea what to use that is an equivalent of apache POI library. Any ideas please anyone? It depends on what you want to do. One option is NPOI , which is a .Net port of Apache POI to .Net Another option is to use IKVM , and then Apache POI itself directly from within .Net. shadeglare You could use Open XML SDK for manipulating MS Office document formats since Office 2007. 来源： https://stackoverflow.com/questions/12300915/what-is-the-c-sharp-equivalent-of-apache-poi-api

I have merged two excel files using the code specied here http://www.coderanch.com/t/614715/Web-Services/java/merge-excel-files this the block applying the styles for my merging cells if (styleMap != null) { if (oldCell.getSheet().getWorkbook() == newCell.getSheet().getWorkbook()) { newCell.setCellStyle(oldCell.getCellStyle()); } else { int stHashCode = oldCell.getCellStyle().hashCode(); XSSFCellStyle newCellStyle = styleMap.get(stHashCode); if (newCellStyle == null) { newCellStyle = newCell.getSheet().getWorkbook().createCellStyle(); newCellStyle.cloneStyleFrom(oldCell.getCellStyle());

I am trying to create cells comments using apache poi. I am able to create the comments, but by default they are always displayed in excel. I have to manual right click on the cell and un-tick show comments to make them invisible(now they appear only when I hover on the cell). Is it possible to make cell comments invisible by default(so that they don't appear in the excel until user hover over the cell.) Here is the code I used : Drawing drawing = cell.getSheet().createDrawingPatriarch(); CreationHelper factory = cell.getSheet().getWorkbook().getCreationHelper(); ClientAnchor anchor = factory

Creating a table in poi was quite easy but it has very limited tutorials and I cannot find one that can create a simple merged cell in a table in generating a docx file. If you have created table, row inside a table and cell inside a row, you can add gridSpan to cell properties: if (cell.getCTTc().getTcPr() == null) cell.getCTTc().addNewTcPr(); if (cell.getCTTc().getTcPr().getGridSpan() == null) cell.getCTTc().getTcPr().addNewGridSpan(); cell.getCTTc().getTcPr().getGridSpan().setVal(2); Note: cell is org.apache.poi.xwpf.usermodel.XWPFTableCell.
