What to do with PermGen space when login WSO2EI 6.1.0

After the successful start of the WSO2 Enterprise Integrator (EI) 6.1.0 I tried to log in the management console and encountered an error java.lang.OutOfMemoryError: PermGen space. Please follow the steps to solve the issue.

WSO2 ESB 4.8.1 support for FileConnector V2

WSO2 ESB File connector version2 introduces the atomic operation related to the file system and allows you to easily manipulate files based on your requirement. The file streaming functionality using Apache Commons I/O lets you copy large files and will reduce the file transfer time between the two file systems resulting in a significant improvement in performance that can be utilised in file operations.

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.

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.

WSO2 ESB Mediator

Mediators provide an easy way of extending the ESB functionalities. WSO2 ESB is based on the WSO2 Carbon platform, which uses OSGI as the underlying technology. It implies everything that runs inside the WSO2 ESB to be OSGI bundles.

WSO2 ESB Feed Inbound Endpoint

Atom 1.0

Atom is the name of an XML-based Web content and metadata syndication format, and an application-level protocol for publishing and editing Web resources belonging to periodically updated websites. All Atom feeds must be well-formed XML documents, and are identified with the application/atom+xml media type.

Getting Started with Simple WSO2 ESB Custom Inbound Endpoint

WSO2 ESB supports several inbound endpoints, but there can be scenarios that require functionality not provided by the existing inbound endpoints. For example, you might need an inbound endpoint to connect to a certain back-end server or vendor specific protocol.

WSO2 ESB Inbound Endpoint

Inbound Endpoint is an endpoint which resides in server side of the ESB. Those are introduced to achieve  some of the main features like multi tenancy support for some protocols like JMS, by passing axis2 layer in  Inbound side,deploying and undeploying inbound endpoints without server restarting. 

 Basically there are two  behaviours introduced. Selection of the behaviour is done according to protocol.

• Polling behaviour
• Listening behaviour    
  

Getting Started with Simple WSO2 ESB Connectors

A WSO2 connector allows you to interact with a third-party product's functionality and data from your ESB message flow, enabling you to connect to and interact with the APIs of services such as Twitter, Salesforce, and JIRA. This means that if you have enabled the Twitter and Google Spreadsheet connectors in your ESB instance,

What is WSO2 Enterprise Service Bus (ESB)

An enterprise service bus (ESB) is a software architecture construct that enables communication among various applications. Instead of having to make each of your applications communicate directly with each other in all their various formats, each application simply communicates with the ESB, which handles transforming and routing the messages to their appropriate destinations.

First Experience in WSO2

WSO2 its an leading open source Srilankan Base Company providing high quality products as open source. so as a new employee i want to say about the working environment of wso2 palm grove office its in kollupitty, srilanka. working in wso2 is an my dream from when i heart about wso2 because of they own passion. 5th of may 2015 i joined as Associate Software Engineer in wso2 from the point I’m starting to write this blog about my experience in wso2 . not only about technical stuff there are more to tell about wso2 experience.
