Vincent,
You could get the size programmatically with a java method such as below. I
commented out the urlConn.getContentLength() as, as you found out that returns
0., But the byte counter loop works:
public int getEADSize(String hostname,String pid) throws Exception {
String urlString = hostname + "/fedora/get/"+pid+"/EAD";
URL url = new URL(urlString);
URLConnection urlConn = url.openConnection();
//int len = urlConn.getContentLength();
InputStream is = urlConn.getInputStream();
int len = 0;
while (is.read()!=-1) {
len++;
}
return len;
}

Thanks for the Replies.
Rebecca, the getSize() returns '0' for Managed Datastreams like the ticket
says. We plan on upgrading but for now, we're locked in with version 3.2 for
at least 6 months.
Kyle, unfortunately the HTTP HEAD request does the same thing. It doesn't
return "Content-Length". When I print getHeaderFieldKey and getHeaderField,
this is what I get (DS1 is the managed datastream I want to grab the info for).

The only work around I can think of is to index the 'filesize' value during
Ingest. Which means we'll have to reindex every object.

The datastream information provided by API-M getDatastream should include the
size of the datastream.
However, there have been issues with datastream size in certain versions of
Fedora, and I think managed datastreams in 3.2 might be problematic. You can
probably confirm by checking on some of your content. The JIRA ticket I'm
thinking of indicates this was fixed in Fedora 3.4:
