From this post I will going to briefly introduce about one of the new features provided by WSO2 ESB . Earlier WSO2 ESB supported static registry keys where users can select a key for the mediator as a static value. But from ESB 4.0.0 users can use dynamic registry keys where users can define XPath expression to evaluate the registry key in run time. For an example let's consider XSLT mediator. With earlier static registry key based method user have to define only single XSLT file for transformation. With the use of dynamic registry key, user will be able to use XPath expressions to dynamically generate the registry key, based on the message context. So with that user can have multiple XSLT files and based on the evaluated key mediator will be able to select the required XSLT file in run time. Following is a sample usage of static and dynamic registry keys and user can use both of them according to situation.   Static Registry Key – define the exact path to find the xslt fil...

Recently my self and few of my friends traveled to the ancient city of Trncomalee which is situated in eastern province and lies on the east cost of the little island. In ancient times it was identified as Gokanna and it was one of the major see ports in the international trading history of Sri Lanka. The city is home to the famous ancient Koneswaram Temple and it is said that this is the capital city of king Ravana . This was my first travel to this ancient city and I would say that, it is one of the best places to visit in Sri Lanka. There are lot of places to visit there including Konesvaram Temple, Dutch Fort, Nilaveli Beach, Marble Beach and Pigeon Island .

In this post I am explaining how to Create a Simple Axis Service(.aar file) and Deploy it in WSO2 Application Server using a simple sample. And also at the end I am describing how to do the same thing with creation of a Jar Service. Lets assume "sample-home" as our parent directory and inside that we can create following folder structure. With this folder structure we can include our external libraries (jar files) inside lib folder and  the "services.xml" file inside "META-INF" folder. Following is the sample services.xml definition which I used with this sample creation. < service name = "HelloService" > < Description > This is a sample service to explain simple aar service </ Description > < messageReceivers > < messageReceiver mep = "http://www.w3.org/2006/01/wsdl/in-out" class = "org.apache.axis2.rpc.receivers.RPCMessageReceiver" /> </ messageReceivers > < parame...
