Hi Brian,
The parser should process the the content of base64 tag in small
chunks. For some reasons it tries to read much more than that in your
setup.
I'll look into it.

Hi Florian,
Here is the exception stack. It looks like it's using the Woodstox
parser (I assume that's what com.ctc.wstx is). The exception is
happening when AtomEntryParser is calling readBase64, so I think it
doesn't like the amount of the base64 encoded content stream. The
rest of the XML, excluding the content stream, is very small.
We don't have control over the Client so our options are limited.

One additional remark:
To avoid the Base64 encoding create an empty document and then set
the content. It's much more efficient when you have to handle
documents of that size.
Or use the Browser binding.

Hi Florian,
The Client is sending the content stream embedded in the
cmisra:content element, so the resulting XML is huge.
<?xml version="1.0" encoding="UTF-8" ?> <entry
xmlns="http://www.w3.org/2005/Atom";
xmlns:app="http://www.w3.org/2007/app";
xmlns:cmisra="http://docs.oasis-open.org/ns/cmis/restatom/200908/";>
<cmisra:content>
<cmisra:mediatype>video/quicktime</cmisra:mediatype>
<cmisra:base64>[base64 encoding of
file]</cmisra:base64></cmisra:content>
<cmisra:object
xmlns:cmis="http://docs.oasis-open.org/ns/cmis/core/200908/";>

Hi Brian,
The CappedInputStream does not limit the content stream, but the
"envelope" around it. In case of the AtomPub binding it is limiting
the size of the XML, but doesn't count the embedded document content.
Could you check how the request is created and if it contains a big
XML portion?
- Florian
Hi,
I've run into a limitation in my CMIS Provider which uses OpenCMIS
0.10.0. When a Client sends a create request to my CMIS Provider and
the accompanying content stream is large, say 1.4 GB,
CappedInputStream raises an exception
CmisInvalidArgumentException("Limit exceeded!").
AtomEntryParser.java creates the CappedInputStream object, passing in
a constant MAX_STREAM_LENGTH which is set to 10 * 1024 * 1024.
public class CappedInputStream extends InputStream {
...
private void checkLength() throws IOException {
if (counter > max) {
throw new CmisInvalidArgumentException("Limit
exceeded!");
}
}
...
}
public class AtomEntryParser {
...
private static final long MAX_STREAM_LENGTH = 10 * 1024 * 1024;
...
public void parse(InputStream stream) throws
XMLStreamException, IOException {
...
cappedStream = new CappedInputStream(stream,
MAX_STREAM_LENGTH);
...
}
}
What can I do to prevent this exception from occurring? I tried
doubling the value, but the exception still occurs.
