问题 I'm trying to use either Apache POI and PDFBox by themselves, or within the context of Apache Tika, to extract and process plain text from MASSIVE Microsoft Office and PDF files (i.e. hundreds of megs in some cases). Also, my application is multi-threaded, so I will be parsing many of these large files concurrently. At that scale, I MUST work with the files in a streaming manner. It's not an option to hold an entire file in main memory at any step along the way. I have seen many source code

问题 This is a follow up question here . I just found this caption in Apache POI website. POI 3.5 and later requires the JDK version 1.5 or later. Versions prior to 3.5 require JDK 1.4+ Clearly, that's the reason I can't build my Java program. I would just like to know if there are any workarounds where I can successfully build my project in Ant using my current settings. Settings Apache POI - 3.9 JDK - 1.4.2 (4.0) Any advice, tips, or hacks are welcome. Thanks in advance! 回答1: Java 1.4 is pretty

问题 I am using Apache POI XSSF to read and write Excel Sheets. I know that I can set the active cell on a worksheet by using Sheet.setActiveCell(CellAddress address) . However, I'd like to set it to a Range containing more than one cell on the sheet, as illustrated by the picture below: When I save a sheet with multiple cells selected using Excel those are selected upon opening the saved file. Is there a way to do this with POI XSSF? 回答1: you can use following line to achieve a ranke as active

问题 I don't have permission to save files to the filesystem. All the examples I could find online are using filesystem.

问题 I'm trying to read and Xslx file using JAVA POI, edit it and save it. But when i change any cell value on row#0 (Header) the output file gets corrupted. Excel can recover the file by repairing, Table from /xl/tables/table.xm . FileInputStream file = new FileInputStream("inventorywithbin431.xlsx"); XSSFWorkbook workbook = (XSSFWorkbook) WorkbookFactory.create(file); XSSFSheet rawdata = workbook.getSheetAt(0); String[] headers = new String[] { "ItemCodeNoFRU","Company","ItemCode","ItemName",

问题 I want to read a XLSX file, so I am using org.apache.poi:poi-ooxml:3.7 Now I have done everything, no errors so far, but when I am running the application, Android Studio is giving me a weird error Error:Execution failed for task ':app:transformClassesWithDexForDebug'. com.android.build.api.transform.TransformException: com.android.ide.common.process.ProcessException: org.gradle.process.internal.ExecException: Process 'command 'C:\Program Files\Java\jdk1.7.0\bin\java.exe'' finished with non

问题 First up I am asking this question from home =- away from all the source; I will attempt to update tomorrow. Essentially I am instantiating NPOIFSFileSystem like so: NPOIFSFileSystem fs = new NPOIFSFileSystem(new File(this.getLocalFile())); The getLocalFile() method returns a String to a file path - I know the file exists in that location. However, the instatiation is returning an error: ArrayIndexOutOfBounds Does anyone have any ideas on this at all? The file in question is an XLS file, it

问题 I am Using poi version : 3.14 I access an Excel ( .xlsx ) file this.workbook = WorkbookFactory.create(new FileInputStream(f.getPath())); this.workbook.setMissingCellPolicy(Row.CREATE_NULL_AS_BLANK); this.sheet = workbook.getSheetAt(0); Here is a custom format found in .xlsx file applied to a cell. I want to display the cell value in my code. As you can see the cell value visible in file is "031642153283700100". Also when i clic on this particular cell, value is changing to "42153283700100"

问题 The situation is as follows; I have a simple program which uses the Apache Poi Library to add one row of data at the end of the an exisiting xlsx file. See below File file = new File(input); XSSFWorkbook workbook = new XSSFWorkbook(file); XSSFSheet sheet = workbook.getSheetAt(0); XSSFRow row = sheet.createRow(sheet.getLastRowNum() + 1); After this I will iterate over the row and set the CellValues. But the problem is that on the second line of the code, as shown above, I get an out of memory
