@Robert Fisher: Would be great if you can go through the source and let me know where you think the implementation is not optimal.

Comment on “Perfbench” update: Tapestry 5 and Grails by Robert Fischer

I’m deeply suspicious of the Grails implementation, since the post login with 20 users apparently took 2.5 seconds. There’s some kind of locking (possibly at the DB?) which is slowing things down artificially. The fact that the “post confirm booking page” is so much faster is really telling.

If you ignore the post login, then the statement “Grails still has some way to go in terms of performance.” is false to fact. It’s right in line with Seam on all the counts.

It is granted that Tapestry and Wicket are faster—neither are as full-featured as Grails (as the comments above note), so I’d expect them to be faster.

Comment on Announcing Flazr – download RTMP (Flash video) streams by Greg

Hello,

I’m using a modified version of the “videolectures.groovy” script to download a file from a rtmp streaming server. Unfortunately, I hit the following exception:

22:45:47,338 [AnonymousIoService-12] INFO [RtmpDecoder] – onStatus code: NetStream.Play.Start
22:45:47,393 [AnonymousIoService-13] INFO [RtmpDecoder] – server notify: [[STRING(0x02) |RtmpSampleAccess], [BOOLEAN(0x01) false]]
22:45:47,393 [AnonymousIoService-13] INFO [RtmpDecoder] – server notify: [[STRING(0x02) onStatus], [OBJECT(0x03) [[STRING(0x02) code: NetStream.Data.Start]]]]
22:45:47,404 [AnonymousIoService-13] ERROR [RtmpClient] – exceptionCaught:
org.apache.mina.filter.codec.ProtocolDecoderException: java.nio.BufferUnderflowException

with a big hexdump following the exception.

flazr is able to connect to the server and seems to start downloading the file. The audio (I’m trying to download an audio-only file) format seems not to be recognized by the RTMP decoder.

Thanks for your help and the great software!

Comment on Wicket and GWT compared with code by Raziel

Given than the evaluation was done a year ago, but there are still recent comments, it’s be interesting to redo the comparison in the latest versions (hint).

Comment on Why you should use the Maven Ant Tasks instead of Maven or Ivy by sj2004

You can use maven assembly only for simple stuff. Anything complicated you have to reply on ant task or write your own mojo.

Thanks for your reply, sir.
I tried flazr-0.6.jar, it doesnt work either.
I have used Wireshark to catch every packet (you can see that in my previous post)and analyze it.I think i am almost there, but some parameters are wrong. I will pay you 10 dollars(via paypal) if you can help me solve this problem.
I have also used RTMPDUMP, it wont work either.
Here is the log produced by RTMPDUMP.1.6:

[edit moved large content to here]

I can connect successfully by using both Flazr and RTMPDUMP, but neither will download successfully.No idea why this happened.

And, this video uses SWF verification, which means the swfurl parameter must be “http://www.nbc.com/assets/video/3-0/swf/videoplayer_extension.swf”.

You can see my Email address.If you can help me or have any suggestions, Please contact me or just reply here.I will pay you 10 dollars for your help.Thanks a lot.

Best Regards, Kankaqi

I hope that one of the fixes took care of this, not sure. Can you download the file from here:

http://flazr.com/files/

And replace the existing JAR file you use, (either rename this file or edit the flazr.bat), let me know how it goes. If this doesn’t fix it, you may have to wait a while, really busy, you could try hack the source of course…

Hi,Sir
I need some help on Flazr.
When I am watching the videos on NBC.com,(http://www.nbc.com/saturday-night-live/video/episodes/?vid=1163334#vid=1163334).I use Replay Media Catcher and Wireshark to catch these packets:
