After the createStreamRequest object is configured, create a stream by calling the createStream method on the client.

After calling createStream, wait for the stream to reach the ACTIVE state before performing any operations on the stream. To check the state of the stream, call the describeStream method.

client.createStream( createStreamRequest );
DescribeStreamRequest describeStreamRequest = new DescribeStreamRequest();
describeStreamRequest.setStreamName( myStreamName );

long startTime = System.currentTimeMillis();
long endTime = startTime + ( 10 * 60 * 1000 );
while ( System.currentTimeMillis() < endTime ) {
  try {
    Thread.sleep(20 * 1000);
  } 
  catch ( Exception e ) {}
  
  try {
    DescribeStreamResult describeStreamResponse = client.describeStream( describeStreamRequest );
    String streamStatus = describeStreamResponse.getStreamDescription().getStreamStatus();
    if ( streamStatus.equals( "ACTIVE" ) ) {
      break;
    }
    //
    // sleep for one second
    //
    try {
      Thread.sleep( 1000 );
    }
    catch ( Exception e ) {}
  }
  catch ( ResourceNotFoundException e ) {}
}
if ( System.currentTimeMillis() >= endTime ) {
  throw new RuntimeException( "Stream " + myStreamName + " never went active" );
}
