#StackBounty: #java #apache-poi #xssf #sxssf SXSSF vs XSSF workbook createSheet() fails on linux environments

Bounty: 50

Was trying to implement an excel export feature on an app using apache POI 3.17.

All was working fine on my local tomcat server and on a windows dev environment. However, the SXSSFWorkbook workbook.createSheet() method fails on a linux tomcat server without throwing any kind of meaningful error (it’s just hanging).

Strangely, the same method on the XSSFWorkbook createSheet class works fine. Below are the snippets of code. Has anyone experienced a similar issue before?

    final SXSSFWorkbook workbook = new SXSSFWorkbook();
    SXSSFSheet sheet = workbook.createSheet("Sheet 1"); //this method fails

    final XSSFWorkbook workbook = new XSSFWorkbook();
    Sheet sheet = workbook.createSheet("Sheet 1"); // this works fine


I created a custom TempFileCreationStrategy to ensure tomcat is writing the file to a directory it has full access to. I can see the file has been created but it’s hanging as it tries to write any data to the file.

I cannot figure this one out.


I’ve enabled POI logging but it I’m still not getting anything meaningful that I can investigate. On my local server POI logging spits out the following as it begins to write the file:

[20:13:05,005]DEBUG (?:?) - Save core properties part
[20:13:05,005]DEBUG (?:?) - Save package relationships
[20:13:05,005]DEBUG (?:?) - Save content types part
[20:13:05,005]DEBUG (?:?) - Save part 'docProps/app.xml'
[20:13:05,005]DEBUG (?:?) - Save part 'docProps/core.xml'
[20:13:05,005]DEBUG (?:?) - Save part 'xl/sharedStrings.xml'
[20:13:05,005]DEBUG (?:?) - Save part 'xl/styles.xml'
[20:13:05,005]DEBUG (?:?) - Save part 'xl/workbook.xml'
[20:13:05,005]DEBUG (?:?) - Save part 'xl/worksheets/sheet1.xml'

On the Linux box, it’s not even getting as far as the first log output. Need to find a way to get more detail about the failure!


Is it possible to get more detailed logging beyond the default logging I have enabled below?

System.setProperty("org.apache.poi.util.POILogger", "org.apache.poi.util.SystemOutLogger" );

String tmpDir = System.getProperty("java.io.tmpdir")+File.separator+"excelfiles";
ExcelFileCreationStrategy tfcs = new ExcelFileCreationStrategy();

try {
} catch (IOException e) {


final SXSSFWorkbook workbook = new SXSSFWorkbook();

LOG.debug("creating work sheet - next line fails");
Sheet sheet = workbook.createSheet(); //hangs here
LOG.debug("It's worked!!!!");
