Thanks. based on your note, I did some further research. I found that
EntityEnclosingMethod supports sending an InputStream. This appears to be
the only one that supports this.
The standard Multipart post accepts java.io.File objects. I'm a bit
confused though. I was interested in having progress on a file by file
basis. It seems like the FilePartSource could be potentially modified to
support this. I searched the commons-dev archives, but I couldn't find
any examples except:
public abstract class EntityEnclosingMethod extends GetMethod {
[...]
private List progressListeners = new ArrayList();
[...]
public void addProgressListener(ProgressListener listener) {
progressListeners.add(listener);
}
public List getProgressListeners() { return progressListeners; }
protected boolean writeRequestBody(
HttpState state, HttpConnection conn) {
//...
if (progressListeners.isEmpty()) {
InputStream instream = getRequestBody();
} else {
InputStream instream = new ProgressInputStream(
getRequestBody(),
getProgressListeners());
}
// ...
}
public class ProgressInputStream extends FilterInputStream {
// ...
public ProgressInputStream(InputStream is, List progressListeners) {
//...
}
// ...
private void bytesRead(int count) {
bytesRead+=count;
if (progressListeners==null || progressListeners.isEmpty()) return;
for (int i=0; i<progressListeners.size();i++) {
ProgressListener l = (ProgressListener)progressListeners.get(i);
if (bytesRead > l.getThreshold()) {
totalBytesRead += bytesRead;
bytesRead = 0;
l.progressAchieved(totalBytesRead);
}
}
}
}
Did I misunderstand your suggestion? I couldn't find anything related to
InputStreams in the MultipartPostMethod.
Thank you,
Brian
