Enterprise Integration for Beginners

This blog post is a continuation to my previous blog post where I have described the concepts of WSO2 ESB transports mechanism. Since we have covered the basics, let's start writing some real code. I will be using the ISO8583 standard as my subject to this custom implementation. I will be grabbing some content from this blog post for my reference to ISO8583 java implementation (Business logic). Thanks Manoj Fernando for writing such an informative post. http://manoj-fernando.blogspot.com/2013/08/iso8583-with-wso2-esb.html Idea of the custom transport implementation is to provide a mechanism to write your business logic which can plug in to the WSO2 ESB runtime. I am not going to tell more about ISO8583 or it's internal implementations. I will be using already implemented java library jPos for this purpose.  It has the functionality to cover the basic use cases of ISO8583 implementations. Sample use case Let’s take the scenario of a certain financial application needi...

WSO2 ESB is considered as one of the best and highest performing open source integration solutions available in the market. One of the astonishing features of the WSO2 ESB is the extensibility of the solution to meet your custom requirements. This means a LOT, if you have dealt with proprietary solutions provided big players (you name it). With this blog post, I will be discussing about one of the not so frequently used but THE BEST extension point in WSO2 ESB which is implementing a custom transport. Given that WSO2 ESB is an extensible solution, that does not mean that it is lacking OOTB features. In fact it provides the most complete feature set provided by any open source integration solution in the market. But as you know, it is not a silver bullet (In fact we can't make silver bullets). Therefore, you may encounter some scenarios where you need to write a custom transport implementation to connect with one of your systems. I will be taking ISO8583 messaging standard to...
