Thanks guys for your replies so far,
I did some logging about the IOException, and here's the message:
"[Microsoft][SQLServer 2000 Driver for JDBC]Object has been closed"
The IOException occurs when Serialize -method is trying to read the
inputstream is. Does this give you any ideas?
Why doesn't this happen with Cocoon 2.1.5???
public void serialize(Response response)
throws IOException, SQLException {
if (this.resource == null) {
throw new SQLException("The Blob is empty!");
}
InputStream is = new BufferedInputStream(this.resource);
long expires = parameters.getParameterAsInteger("expires", -1);
if (expires > 0) {
response.setDateHeader("Expires", System.currentTimeMillis() +
expires);
}
response.setHeader("Accept-Ranges", "bytes");
byte[] buffer = new byte[8192];
int length = -1;
while ((length = is.read(buffer)) > -1) {
^^^^^^^^^^^^^^^
out.write(buffer, 0, length);
}
is.close();
out.flush();
}
Should this be continued on dev-list only?

Thanks, I tested the sample, and it does work with HSQLDB. But when I
tested it against SQL Server with similar results I got before: Upload
works but reading the file with DatabaseReader returns 0 bytes. :(
So, my guess is, something has changed between 2.1.5 and 2.1.7 that makes
the JDBC driver for SQL Server incompatible with Cocoon. With the jar-files
from 2.1.5 (same setup otherwise) this works. What could this change be?
The method that throws this error "Assuming client reset stream" in
DatabaseReader.java is:
public void generate() throws ProcessingException, SAXException,
IOException {
try {
Response response = ObjectModelHelper.getResponse(objectModel);
this.serialize(response);
} catch (IOException ioe) {
getLogger().warn("Assuming client reset stream");
Try to log the IOException or do some remote debugging to find out the
reason.
