WebSphere Command Pattern

[Nagendra Prasad]

Hello Ranchers,
I have embarked on this journey to trace the current state of what used to be called the 'WebSphere Command Pattern'. This was once upon a time a well documented feature from one of the better redbooks from IBM. (sg245754 Design and Implement Servlets, JSPs, and EJBs for WebSphere).
For quite a while, all references to this have vanished every where!!! The IBM site does not have any more information on this. Their new patterns site is a bit confusing to say the least.
Was something intrinsically wrong with their implementation of this pattern? Is is not suggested for use any more?
Are there people out there who have used this in their projects? Did they face roadblocks which meant they used an alternate approach?
And, are they alternate approaches to this pattern that people can share with me please?
I am looking for some good discussion. There are aspects which probably need to be talked abt and only then might we get all issues out in the open
Hoping to hear from u all
Nagendra Prasad.

've got a copy of that redbook; if you send me an email address, i'll send you a url to it.

Sorry.. I meant references in general to the usage of the command pattern, not the book itself.
Nobody seems to be using the WebSphere Command Pattern anymore.. there is not a trace of it in any of the disc. forums.. and certainly not with any of the struts with WSAD thing, though we feel it kind of fits very well into the struts framework.
So, the actual question is "What exactly is happening with the WebSphere Command Pattern"
Any thoughts/comments....
Thanks a ton.

Are you refferring to the WebSphere Control Program? It's more commonly refered to as WSCP and we use it heavily.
If so this link is what you're looking for

Coreolyn,
No.. wscp is more of a command utility for websphere. It is more of a administrative tool.
Command Pattern on the other hand is a design pattern that was being suggested by IBM. It was a way of decoupling the presentation and logic layers in an application through the use of 'commands'.
Best Regards,

Hi Naga
We have used the command pattern architecture for one of our product.The performance of the product is very good. We went using VO's,DAO's,Commands and Controller servlet for that.The only disadvantage is The product will become sensitive in the sense if any install on webpshere happens there is a chance of images not getting displayed in the browser etc., then explicitly the services in the xmi file should be enabled.
In general Command pattern architecture is good
Thanks

The WebSphere command framework has moved into the WebSphere base classes in WAS 5.0. In fact, it's now part of the WebSphere dynamic caching feature. See this this article for more information on using it.
