hello,
I have a jsp with a form allowing to upload a file in pdf format; the file is
then stored in an Oracle database as a BLOB object. This part works fine : if I
retrieve the file directly from the database everything is ok.
But I have another jsp that allows to download the same file, and this doesn't
work properly. When I save the file and then open it, it appears as blank. The
size of the downloaded file is smaller than the original one (10.1 Ko instead
of 10.7 Ko).
I tried with another file, which size is 11.2 Ko, and when I download it, the
resulting file is 10.6 Ko.
Here is the function called to download the file :
public Resolution showContent() {
final byte[] is =
this.contractContentService.get(this.getIdContractContent()).getByteContent();
StreamingResolution res = new
StreamingResolution("application/pdf") {
@Override
protected void
stream(javax.servlet.http.HttpServletResponse response) throws Exception {
String value = new String(is);
response.getWriter().write(value);
}
}.setFilename("contract.pdf");
res.setCharacterEncoding(null);
return res;
}
contractContentService is a service that retrieves the BLOB object from the
database, and getByteContent() returns the content of the file as a byte array.
This function works perfectly if I retrieve a txt file from the database.
Anyone has an idea the problem might be for a pdf file?
Thanks
