copied!<p>To check progress using HttpClient, wrap the MultipartRequestEntity around one that counts the bytes being sent. Wrapper is below:</p> <pre><code>import java.io.FilterOutputStream; import java.io.IOException; import java.io.OutputStream; import org.apache.commons.httpclient.methods.RequestEntity; public class CountingMultipartRequestEntity implements RequestEntity { private final RequestEntity delegate; private final ProgressListener listener; public CountingMultipartRequestEntity(final RequestEntity entity, final ProgressListener listener) { super(); this.delegate = entity; this.listener = listener; } public long getContentLength() { return this.delegate.getContentLength(); } public String getContentType() { return this.delegate.getContentType(); } public boolean isRepeatable() { return this.delegate.isRepeatable(); } public void writeRequest(final OutputStream out) throws IOException { this.delegate.writeRequest(new CountingOutputStream(out, this.listener)); } public static interface ProgressListener { void transferred(long num); } public static class CountingOutputStream extends FilterOutputStream { private final ProgressListener listener; private long transferred; public CountingOutputStream(final OutputStream out, final ProgressListener listener) { super(out); this.listener = listener; this.transferred = 0; } public void write(byte[] b, int off, int len) throws IOException { out.write(b, off, len); this.transferred += len; this.listener.transferred(this.transferred); } public void write(int b) throws IOException { out.write(b); this.transferred++; this.listener.transferred(this.transferred); } } } </code></pre> <p>Then implements a ProgressListener which updates a progress bar.<br> Remember that the progress bar update must not run on the Event Dispatch Thread.</p>
