WSO2 Jaffna: Extending Platforms meetup - 01

How does the WSO2 platform work, and how can you contribute while studying? If you're a student at the University of Jaffna, join us as we discuss extensions and how to begin your journey of open source contribution.

This is the summery of meetup if some one miss the meetup please find the slides here.

Federated Authenticator in WSO2 Identity Server 5.1.0

An authenticator allows you to authenticate the user using third party authentication systems such as LinkedIn, Clef and Foursquare. You can configure the authenticators for your identity provider to reach out to third party authentication systems to authenticate a user who logs in to your application. For example, if you configure LinkedIn authenticator as your authenticator in WSO2 Identity Server, you can authenticate a user of your application using LinkedIn authentication. You can also do the authentication with multiple third party authentication systems with a single authentication request called multifactor authentication .

Pass Dynamic Values through Class Mediator in ESB Connector methods

In this post, let's discuss how we can pass a dynamic number of arguments  to connector methods, Normally we work with pre-defined parameters in connector  but here let's see how we can pass dynamic parameters with dynamic value and name and how we can use inside the connector method.

There are two types of actions we can do to get dynamic parameters. First one is set some key values and get the values start with that key value another method is through some pre-defined keywords.

Git for Team Projects

In this post, I'm gonna explain how to use Git for our personal projects and contribute to others projects most importantly team works.  We assume that every reader knows about Git before this post. Git is a free and open source distributed version control system designed to handle everything from small to very large projects with speed and efficiency.  Git is easy to learn and has a tiny footprint with lightning fast performance. It outclasses SCM tools like Subversion, CVS, Perforce, and ClearCase with features like cheap local branching, convenient staging areas, and multiple workflows.

WSO2 Identity Server Dropbox Authenticator

Each authenticator provides you a way to authenticate the user using specific external authentication system. For example if you want to authenticate a user who logs into your application using Dropbox authenticator, you need to configure the Dropbox authenticator for your identity provider .The Dropbox authenticator allows you to authenticate user using Dropbox through WSO2 IS. 

Creating WSO2 IS Custom Federated Authenticator

WSO2 IS custom authenticators provides you a way to authenticate the user using specific external authentication system. through the authenticators we can secure our systems. Before start development Research the APIs provided by the service for which you want to create an authenticator.

Run Integration Test with WSO2 ESB EJB2 Connector and Jboss 5.1

As we discussed earlier EJB2 connector is a tool to make calls between remote EJB2.X objects and wso2 ESB. there are two type of calls we can call.Stateless and stateful where stateless is a one time call and stateful maintain a state between remote object and client. Integration Test for EJB2.X connector written based on Jboss 5.1 server so there are some pre configuration we need to  set before we run the integration test.

in this blog lets see how to configure ESB before run the test and what are the libraries we need to add to ESB and Test Client. Integration test is very important to check the stability of connector(to validate the methods).

WSO2 ESB EJB 2.x Connector

Enterprise JavaBeans is an architecture for transactional, component-based distributed computing. The specification for EJBs lays out not just the format of a bean itself, but also a set of services that must be provided by the container in which the bean runs. This makes EJBs a powerful development methodology for distributed application development. Neither the bean developer nor the client application programmer needs to be concerned with service details such as transaction support, security, remote object access, and many other complicated and error-prone issues. These are provided transparently for the developers by the EJB server and container.

Writing WSO2 ESB Connector Integration Test

We assume that readers have basic knowledge about TestNG and Connector. If not please get the knowledge about connector development from here before read this post. In this post we are analyzing how we can implement a connector integration test. Integration test is very important to evaluate the effectiveness of the connector functions. This post will focus on integration test based on Hello World Sample. 

Getting Started with Simple wso2 ESB EJB Mediator Sample

The EJB mediator calls an external Enterprise JavaBean(EJB) and stores the result in the message payload or in a message context property. Currently, this mediator supports EJB3 Stateless Session Beans and Stateful Session Beans.

Getting Started with Simple Remote EJB 3.X Server Sample

This sample will give you a simple working experience with EJB client server . here I’m using netbeans as IDE and JBoss 5.1 as my EJB Container. and I created seperate client for Stateful an Stateless EJB sessions  in order to make easy the development .We'll create a ejb module project named EJBTestServer.

Getting Started with Simple RMI services

Writing your own RMI services can be a little difficult at first, so we'll start off with an example which isn't too ambitious.In this example, we have followed all the 6 steps to create and run the rmi application. The client application need only two files, remote interface and client application. In the rmi application, both client and server interacts with the remote interface. The client application invokes methods on the

JAVA Remote Method Invocation (RMI)

Remote method invocation allows applications to call object methods located remotely, sharing resources and processing load across systems. Unlike other systems for remote execution which require that only simple data types or defined structures be passed to and from methods, RMI allows any Java object type to be used - even if the client or server has never encountered it before. RMI allows both client and server to dynamically load new object types as required.

Study About Enterprise Java Beans (EJB) Introduction

Enterprise Java Beans (EJB) is a development architecture for building highly scalable and robust enterprise level applications to be deployed on J2EE compliant Application Server such as JBOSS, Web Logic etc.

A recent study by Java developer Raghu Kodali has shown that porting Sun's Java EE tutorial application RosterApp from EJB 2.1 to EJB 3.0 resulted in
