Exec Maven Plugin

This plugin is very useful while executing system and java programs.It provides two goals as;

exec:exec execute programs and Java programs in a separate process.

exec:java execute Java programs in the same VM.

The benefit of this plugin is we can execute the program without any IDE and using this maven plugin.

I will explain how to use exec:java goal in a simple helloWorld program.

First create a new maven project.Here I used IntelliJIDEA.
Then add a java class to it with having the main method.For the moment just add a System.out in that method.

Then add the following configurations to it's pom.xml file.

Next build the project using 'mvn install' .
Finally invoke 'mvn exec:java -o'.
Then the program will execute and the terminal result will displays as follows.

Convert an InputStream to XML

For that we can use DocumentBuilder class in java. By using the method parse(InputStream) ; A new DOM Document object will return. InputStream input; DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance(); DocumentBuilder parser = factory.newDocumentBuilder(); Document dc= parser.parse(input); In the above code segment,by using the created Document object,the corresponding XML file for the inputStream can be accessed.

Concat two xml values with XSLT

The use-case described in this blog-post,is there's an WSO2 ESB node setup to proxy an incoming message to a particular back-end endpoint. Before delivering the message to the back-end endpoint,from the ESB node itself,this incoming message need to processed and change its inside xml payload format. For eg: Below is the incoming message <?xml version="1.0" encoding="UTF-8"?> <CinemaHall name="liberty"> <OwnerData> <Name>John Smith</Name> <openedDate>12/12/80</openedDate> <quality>good</quality> </OwnerData> <CinemaHallData> <rows>100</rows> <seats> <seat>50</seat> <seat>60</seat> </seats> </CinemaHallData> </CinemaHall> This message need to be changed as below; <?xml version="1.0" encoding="UTF-8"?> <CinemaHall name="liberty"...

Passing end-user details from client to real backend endpoint via JWT token

In real-world business system,WSO2 API Manager useful on exposing company APIs, in a secured and controlled manner with the features provided by APIManager as; OAuth support [To secure API invocations] Throttling support [To control API invocations] Monitoring support [To track API usage] More technically what happening is when a user sends a particular API request,it will goes to WSO2 APIManager node and from there,the request will route to the real implemented back-end endpoint of the particular API and get back the response and returned it to the API invoked user. There can be a use-case,that this back-end endpoint may expect the details of API invoked user as to pass those details to some internal company usage as; Additional authentication/authorization Track usage data from an internal system. So how to support above requirement from WSO2 AM. There comes the use of JSON Web Token[JWT] implementation done inside WSO2 AM. JWT is a means of representing claims to...
