[ANN] Announcing the Dynamic Mashup Server

ALT Mobile DEV
To commemorate Grizzly's open source birthday, I just announced the <alt> Dynamic Mashup Server on the company blog. Truth be told, we launched the blog just for Grizzly :-)

Dynamic Mashup Server Debuts
Tuesday, February 5, 2008

We are pleased to announce the <alt> Dynamic Mashup Server. Built to support internet scale amalgamation of web content, the Dynamic Mashup Server is the industry’s first Comet enabled mash-up server. 

Implementing all of the major AJAX and Comet technologies such as XHR multipart, forever frame, XHR streaming, and forever script;  the Dynamic Mashup Server supports HTTP Streaming to desktop browsers as well as Safari on iPhone. Single-site browsers (SSB) such as Mozilla's Prism  and widget platforms such as Opera Widgets, Microsoft Vista Sidebar Gadgets, and Mac OS X Dashboard are also supported clients.

Comet services are provided through a custom version of Sun's Grizzly web server technology.


Other cool features of the Dynamic Mashup Server include RSS mash-up feed generation and text-to-speech output to support visually impaired user access.

Implemented to run on 64-bit Java Virtual Machines, the Dynamic Mashup Server integrates into our virtual Web 2.0 containers which provide isolated access and execution of remote web content ensuring that mash-up clients are protected from potentially harmful HTML and JavaScript. Mash-up isolation is also necessary to avoid XSS attacks.

The perfect companion to our Web 2.0 developer tools, the Dynamic Mashup Server supports mash-up RDF meta models which provide a realistic implementation of the semantic web.

The <alt> Dynamic Mashup Server will be available in Q2 of this year.

Re: [ANN] Announcing the Dynamic Mashup Server

ALT Mobile DEV
thanks for saying so :-)


we've been working hard for more than 5 years on our mash-up technologies. In fact, the Swing team did a little blurb on our visual mash-up developer tools used to extract/convert HTML to WML-- the old wireless markup.  Here's a screen shot from 2003 (from Swing Sightings #15) of our Mashup developer tool extracting an HTML TABLE element of WiFi hotspots and then transcoding it to a WML table:



Of course, in 2003 nobody called it mash-up or Web 2.0. In fact, in most of our documentation we still use the engineering term "transcoding".

In reply to this post by ALT Mobile DEV

Well done, that sounds like a great project.

 

But I am curious...  have you experienced any problems with the Mashup Server and anti-virus or firewall software?  I have found that Comet data seems to be blocked by some such programs.  Specifically, Kaspersky Internet Security 7.0 running on Vista x64 suspects that Comet traffic is not legitimate HTTP data and blocks it in its default configuration.  Some tweaking can get around this but it concerns me that Comet-enabled web sites may not load when this software is installed and this would greatly discourage users who are unlikely to be patient enough to fiddle with the settings to get things to work.

 

I have tested my use of Comet on Windows Server 2003 and XP as well with other AV and firewall software and no such problems emerged.  So far, the problem only happens with Vista and Kaspersky but there’s no reason to think that other systems that offer advanced protection would necessarily be immune from it as well.

 

So I would be very interested to hear you feedback on this.

 

Thanks,

 

John

Re: [ANN] Announcing the Dynamic Mashup Server

ALT Mobile DEV
Hi John,

thanks for the encouragement :-)

No, not yet... but I don't test against 3rd party AV. I have done some  
long running tests which include disconnecting both the client and  
server and then restoring the connections and that works depending on  
the type of Comet connection. I've done lots and lots of iPhone Comet  
testing against our Dynamic Mashup Server with fabulous results.

So 64-bit Vista has taken a back seat to the iPhone. We support Vista  
Sidebar Gadget development in our Web 2.0 developer tools so it's just  
a matter of time for me to try out that configuration.


The Dynamic Mashup Server embeds Grizzly with Grizzlets so I have a  
bit better control over the environment than just using the GlassFish  
install or Grizzly with Jetty, etc. I did experience the "Comet data  
into the bit bucket" issue when I was using various threads to start  
embedded Grizzly. Since I think you are using Servlets, are you sure  
that you are abiding with the threading rules for Servlet containers?

That's what I thought might be your problem but I wanted to ask  
Jeanfrancois first... but since you asked...

If I remember the Servlet spec, you can spawn threads at your leisure  
but can only post to the Response output stream from its thread and  
not yours. Perhaps your thread is getting GCed?


The other possible issue which also may be categorized as the "Comet  
data into the bit bucket" issue is that the browser might be  
internally stopping the connection without warning. I think that this  
happens when you send more than 8 MB of data over the life of the  
Comet connection-- depending on the type of Comet connection.

This is empirical and not based on vendor information. In fact the  
only HTTP size limits that I've seen come from Apple regarding the  
iPhone and IIRC that's 10 MB per HTTP connection... but does a Comet  
connection which progressively sends its data without disconnect/
reconnect and runs the JavaScript engine, etc. different from a 10 MG  
image download? I haven't tested this to see. Opera engineers have  
discussed connection timeouts wrt Opera Widgets... but I don't know  
about IE and FireFox definitely. Don't forget that Vista allows the  
connection to be made and then prompts you for permission after the  
first HTTP send/receive transaction. That's what I've noticed.

So which browser are you using on Vista? and what's the Comet type?  
JavaScript code?



For the Dynamic Mashup Server, I've implemented the following Comet  
types:

1. XHR multipart (for FireFox)
2. Forever frame
3. XHR streaming (for FireFox and uses XHR readyState 3 instead of the  
typical XHR readyState 4)
4. Forever script

So with that said I would try to get everything working on Vista with  
FireFox and FireBug first and then try IE with their developer tools  
also installed.


I'm hopping to have a demo Comet site for the Dynamic Mashup Server  
ready next week so that might be an alternative also to determine the  
actual source of the problem: client, server, or... South Park  
underwear gnomes :-)))


so perhaps server thread, client timeout, HTTP size, or AV might be  
the issue.


best of luck.

RE: [ANN] Announcing the Dynamic Mashup Server

John C. Turnbull
Hi Zaid,

Thank you for taking to the time to reply to my request.

I think I may have confused everyone with my problems with Comet.  I
actually have 2 outstanding problems that may or may not be related.  One is
the problem with firewalls and AV and the other is the problem with dropouts
after an hour or so of idle time.

The problem with dropouts (or "Comet data into the bit bucket") is less
concerning to me than the other and I have put further investigation of it
in abeyance for now as I rewrite the servlets concerned for other reasons.
The problem with AV/firewalls is my top priority.

Further comments inline.

> thanks for the encouragement :-)

[JCT] You deserve it!

[JCT] Yes, I believe I am doing things correctly thread-wise but I will have
another look at things to be sure.  Thanks for the tip.

[JCT] You may be onto something here.  But why would the thread get GCed if
it's still alive?

[JCT] I don't think this is the reason as the dropouts are occurring even
when almost no data has been transmitted.  It definitely seems to be only
related to time.

[JCT] For browsers, I have tried both IE 7 and Firefox 2.

The actual Comet type is interesting.  We are completely unsure what to set
as the content type in the servlet response because what we are transmitting
is actually serialized Java objects.  Which content type would correspond
with that?

You may well have helped diagnose the dropouts problem and the AV/firewall
issue may be related to the content type not being set correctly leading to
the AV software thinking that the data may be a virus or other threat.

I will keep you posted on what I discover in the course of further
investigation and thanks for your input.

Cheers,

John
