I am writing some code to import Excel files to database. The files could be big (thousands of rows), so I am using the Event API. POI version is 3.9
I am opening the file like this: FileInputStream fin = new FileInputStream(file);
//create record listener
HSSFRecordListener mainListener = new HSSFRecordListener("aaa.xls");
// create a new org.apache.poi.poifs.filesystem.Filesystem
POIFSFileSystem poifs = new POIFSFileSystem(fin);
// get the Workbook (excel part) stream in a InputStream
din = poifs.createDocumentInputStream("Workbook");
Some files are cousing the last line to throw FileNotFoundException.
Indeed, if I open those files with 7zip, there is no Workbook
entry, but there is Book
instead.
I have tried to work around this by opening the Book
entry if Workbook
is not found.
try {
din = poifs.createDocumentInputStream("Workbook");
} catch (FileNotFoundException e) {
try {
din = poifs.createDocumentInputStream("Book");
} catch (FileNotFoundException e1) {
FileNotFoundException e2 = new FileNotFoundException("Neither Workbook nor Book found in file!");
e2.initCause(e1);
throw e2;
}
}
This results in another exception:

Google have some info about fixed bugs in POI 3.2 and 3.7 which have something to do with exception Not enough data (0) to read requested (2) bytes
, but it seems that it was something else.
The same files can be opened successfully in Excel 2007. When I save them manually with Save As=>Excel 97/2003
, 7zip shows that the Book
entry have been replaced with Workbook
and I can successfully import them with Apache POI.
Did anyone found this issue? How to workaround it?
EDIT
The problem is when I try to open files saved in Microsoft Excel 5.0/95 file format.
To reproduce this issue create new spreadsheet, enter any data, and save as => Microsoft Excel 5.0/95 Workbook (*.xls).
Is there any way to read this format with apache POI or do I have to force my users to upgrade their workbooks before uploading?
Not enough data (0) to read requested (2) bytes
error seems to indicate it's an old or non-standard file... – GagravarrMicrosoft Excel 5.0/95
