I’ve run into an issue downloading content using the OpenCMIS 0.4.0
build running under WL 10.3.5. Our code works ok under Tomcat v7 and
also when unit tested in Eclipse Helios. But under WL 10.3.5, the
OpenCMIS code path that gets invoked for downloading content (through
CmisObject.getContentStream()) eventually makes an HTTP POST request
using the HttpUtils.invoke() method. In that class in the 0.4.0 code
base, there’s a line of code (line 167) that looks like this:
OutputStream out = new BufferedOutputStream(conn.getOutputStream(),
BUFFER_SIZE);
In the 0.4.0 code base, the value for BUFFER_SIZE is set to this:
private static final int BUFFER_SIZE = 2 * 1024 * 1024;
The code then sets HTTP 1.1 chunking with this fragment of code:
// send data
if (writer != null) {
conn.setChunkedStreamingMode(BUFFER_SIZE);
OutputStream out = new BufferedOutputStream(conn.getOutputStream(),
BUFFER_SIZE);
writer.write(out);
out.flush();
}
Under WL 10.3, trying to do a POST with this big a buffer causes the
write to fail with an error message that the buffer size must be < 64kb
in size. This code worked ok under WL 9 but doesn’t work under 10.3.5.
Apparently there’s some new throttling policy on max buffer size that is
given to applications. We changed the definition of BUFFER_SIZE to be a
bit less than 64k and this solved the issue.
Seems like this change should be put back into the mainstream code base?
If this seems right, I’ll post a bug on this and you guys can fix it in
0.5.0.
thx,
