Hi Jose,
you've noticed before that OPCPackage has a problem with the jasper output, so
don't use it for now.
When you write "POIFSFileSystem fs = new POIFSFileSystem(inputStream);" what is
inputStream refering to?
Just try it without the inputStream:
JRXlsAbstractExporter exporter = new JRXlsxExporter();
ByteArrayOutputStream outputStream = new ByteArrayOutputStream();
...
exporter.setParameter(JRXlsExporterParameter.OUTPUT_STREAM, outputStream);
....
exporter.exportReport();
POIFSFileSystem fs = new POIFSFileSystem();
EncryptionInfo info = new EncryptionInfo(fs, EncryptionMode.agile);
Encryptor enc = info.getEncryptor();
enc.confirmPassword("testPass");
OutputStream os = enc.getDataStream(fs);
outputStream.writeTo(os);
FileOutputStream encryptedXlsx = new FileOutputStream("test.xlsx");
fs.writeFilesystem(encryptedXlsx);
encryptedXlsx.close();
If this also doesn't work, please send me the unencrypted xlsx to my private
email address and I'll have a look, what's wrong with it.
Best wishes,
Andi
