I'll watch out for 2 things:
- The byte array is available when the response.write() occurs (transactions
and DB access)
- The resolution subclass is unnecessary in this case
Better replace that code with this one:
public Resolution showContent() {
final byte[] is =
this.contractContentService.get(this.getIdContractContent()).getByteContent(
);
StreamingResolution res = new StreamingResolution("application/pdf", new
ByteArrayInputStream(is)).setFilename("contract.pdf");
return res;
}
Hope it helps!

Asunto: [Stripes-users] problem downloadin a pdf file using Stripes
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
