Jacinto Verdaguer commented on ODFTOOLKIT-377:
----------------------------------------------
For files larger than 3 MB the method fails is:
private InputStream readAsInputStream(ZipInputStream inputStream) throws
IOException {
ByteArrayOutputStream outputStream = new ByteArrayOutputStream();
if (outputStream != null) {
byte[] buf = new byte[4096];
int r = 0;
while ((r = inputStream.read(buf, 0, 4096)) > -1) {
outputStream.write(buf, 0, r);
}
inputStream.close();
}
return new ByteArrayInputStream(outputStream.toByteArray());
}
Specifically the line: outputStream.write(buf, 0, r);
This method is in the class ZipHelper.java

> I'm modifying file metadata .ods, the application works correctly for files
> under 3 MB but in the case of files larger of 2,8 MB it creates a file 2 KB
> and get locked by the java process. No java error display.
> My code is as follows:
> doc = OdfDocument.loadDocument(new File("C:\tmp\ficheroIn.ods"));
> OdfFileDom metadom = doc.getMetaDom();
> Meta metadata = new Meta(metadom);
> metadata.setTitle(plantilla.getTitulo());
> metadata.setSubject(plantilla.getAsunto());
> metadata.setCreator(plantilla.getModificadoPor());
> metadata.setDescription(plantilla.getComentarios());
> doc.save("C:\tmp\ficheroOut.ods");
