java.io.EOFException: Unexpected end of ZLIB input stream using Apache POI

Андрей Суручану :

I try to create Excel Pivot Table using Apache POI.
At the moment, when I try to write data in a workbook workbook.write(fileOut); I get exception

org.apache.poi.ooxml.POIXMLException: java.io.EOFException: Unexpected end of ZLIB input stream

There is the code of the class:

public class PivotTable {



public static void createPivotTable(String pathToWorkbook, String sheetName) throws IOException {

    Workbook workbook = new XSSFWorkbook(pathToWorkbook);

    XSSFSheet sheet = (XSSFSheet) workbook.getSheet(sheetName);

    int firstRowInd = sheet.getFirstRowNum();
    int lastRowInd = sheet.getLastRowNum();
    int firstCellInd = sheet.getRow(0).getFirstCellNum();
    int lastCellInd = sheet.getRow(0).getLastCellNum() - 1;

    //Specifying top left ant the bottom right of the table data
    CellReference topLeft = new CellReference(firstRowInd, firstCellInd);
    CellReference botRight = new CellReference(lastRowInd, lastCellInd);

    //The area of data in table
    AreaReference aref = new AreaReference(topLeft, botRight, SpreadsheetVersion.EXCEL2007);

    //Position of the pivot table
    CellReference pos = new CellReference(firstRowInd + 4, lastCellInd + 1);

    //Creating the pivot table
    XSSFPivotTable pivotTable = sheet.createPivotTable(aref, pos);


    pivotTable.addRowLabel(0);
    pivotTable.addRowLabel(2);
    pivotTable.addColLabel(3);

    FileOutputStream fileOut = new FileOutputStream(pathToWorkbook);
    workbook.write(fileOut);
    fileOut.close();


}

And there is the StackTrace of Exception:

Pretty sure the problem is you overwriting the file. Try to save to a different path. If you still want to overwrite the file, save to something else, delete the original, then rename the file you wrote into place:

try (FileOutputStream fileOut = new FileOutputStream(pathToWorkbook + ".new")) {
    workbook.write(fileOut);
}
Files.delete(Paths.get(pathToWorkbook));
Files.move(Paths.get(pathToWorkbook + ".new"), Paths.get(pathToWorkbook));
