I suppose you have used this combination in production environment and got some numbers (response times and resource usage, cpu and memory) to share. After my last post we are using BlazeDS for a chat application and I am yet to become comfortable to recommend it to the world. So if you do have numbers please share them. The numbers I am working with in production are: 32 MB tomcat process, 20ms avg server response time and <10% CPU usage on a standard Amazon EC2 instance. This supports about 600 users on 2 applications (in the same tomcat) - roughly 60 of them are online at any time. @Steven Libonati

This is an amazingly powerful combination. What you get is a portable .war or .ear that is deployable in any JEE server. @Sunil Guttula

There are not too many good options for connecting Flex with a backend java server. The open source options available in May 2007 (GraniteDS) did not really work well, lot of configuration and no support for custom classloaders on server side. BlazeDS from Adobe and Hessian (from Caucho) are 2 more options now and graniteds may have matured more. Hessian is a clean one, not know too much about BlazedS. We have developed a bridge from Flex to Java (needs Servlet container) using xml as the data format and is working quite well. We are using Flex to build an enterprise product and it has worked well.

I understand that FDS is one of Adobe's few opportunities to make $$ from Flex, but IMO the fees for it are very very high. The 30-minute test drive, for example, is the type of sample I'd like to see but provided without a requirement on FDS. Its a little disigenuous to advertise Flex as becoming open and not requiring FDS to build many types of enterprise applications, but then to not provide a decent samples or guidance on how to do this. Or have I been Googling in the wrong places ;). Given the huge amount of collateral that James, Bruce, Christophe, and other Flex experts have provided it would be nice to see something of substance describing the non-FDS scenario. Any good pointers for to samples or tutorials for this?

Data Services.. what do you suggest james.. looking forward your suggestion Thanks, rathu Hi James,

Not being familiar with Picnik, I went to the linked Showcase page to find it. After a pretty long load time, I was presented with a pretty list of apps in a statically sized box that could not be scrolled with my mouse's scrollwheel. I could not search for Picnik using my browser's search functionality and the app provided none. I gave up looking for Picnik and thought I would try another app, which I attempted to open in a new tab by middle-clicking or right-clicking to bring up the familiar browser menu. No such luck. Flash is a frustrating technology. I got stuck at the pros. Not being familiar with Picnik, I went to the linked Showcase page to find it.

I needed something to get started on quickly, understand and evaluate and determine if I could really use it with my limited skill sets (first foray into the flex world). It is safe to say that I did not find the tools available to me that would allow me to play with the technology a first step to getting started. Without the tools the technology is for technology developers not for the technology users. Suffice to say I have since not visited Flex/Flash land, I guess it might be worth looking at once more.
