Flex calls to Web services through Apache Axis2 engine.

There are quiet a few ways to create and deploy your Web services,the one best way to do this is by using Apache Axis2.Its easy,simple,efficient,flexible… [feature list can be found on their official website] and cost free. 

What is Apache Axis2?

In very simple terms “It is an implementation of SOAP[Simple Object Access Protocol]“.

[For more info...]

There are two implementations of the Apache Axis2 Web services engine – Apache Axis2/Java and Apache Axis2/C.

The below figure shows the flow for Apache Axis2/Java, which i have been working on now.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

It is very brief and the actuall internal flow and Architecture of the Apache Axis2 can be found on their website.

Flex framework uses WebService Class to access SOAP-based Web services on remote servers which define their interfaces in a WSDL document.As Apache Axis2 is an implementation of SOAP, acts as an intermediate layer or engine between service requester [Flex using WebService Class] and service provider.

Web services have been criticised for their complex Web structures for deployment and performance.But as these frameworks for Web services emerge with simplicity, they are no longer a concern.Soon i will come up with a post on creating and deploying Web services Using Apache Axis2/Java.

Enjoy the post.

birdeye ???

Adobe Charts for Flex has a good set of Components from which we can make attractive pictorial representations of Data.
But let me tell they dont satify the very good needs of the funtional requirements like we have.Like if i want to draw a Graph in Flex using the Adobe Charts for Flex then i would end up like “can i do that ??”,since i dont have much time on R&D i googled and found one interesting kit called birdeye.

What is birdeye?
open source information visualization and visual analytics library for Adobe Flex.

They have few cool kits.I used one of the kit[Relational Analysis] and made a Graph according to the need in to my live project.Thanks to the team behind birdeye.

Run Demo

Its the Binomial Tree Distribution which represents the Option Pricing[Finance concept].
