Web services

Different groups within an organization need to monitor different Key Performance Indicators (KPIs) - An operations team will be interested in the response times of business services and loads of each service, while members of a business unit will be interested in sales per day, sales trends by hour per day etc. The diverse requirements of each group would potentially result in countless hours spent on customizing a solution.

When you write a complex mashup with WSO2 Mashup Server which aggregate several external web services, you will definitely need to communicate with secured web services. It is very easy with WSO2 Mashup Server as it does this with service composition. In this article, we will discuss how WSO2 Mashup Server allows you to invoke services secured with advanced security scenarios.

OracleAQ provides database integrated messaging functionality. Its' underlying system works with oracle database. OracleJMS (OJMS) is the JMS interface to the Advanced Queuing (AQ) feature in the Oracle database. OJMS has JNDI support, which could be used to get 'ConnectionFactory' at run time and the connections returned from it will be able to transparently connect to the JMS server.

In this tutorial, we will look at the configurations for WSO2 ESB to work with OracleAQ as the messaging media.

In the modern enterprise, complex business requirements are increasingly satisfied by a combination of new and existing services. Getting the right bits of information at the right place, at the right time, in the right format, and with the right protocol can be a challenge. The WSO2 Enterprise Service Bus (ESB) provides a simple solution to this integration problem by providing a rich set of integration capabilities for robust, scalable and seamless integration of such services.

Moving a software architecture to service orientation provides clear benefits, including business agility, operational excellence, and the enablement of innovation. However, it brings challenges as well. In his keynote presentation at WSO2Con 2011, Mr. Malladi drew on his experiences at eBay, the world’s largest online marketplace, to outline recommendations for successful service orientation. Along the way, he dispelled some common myths. Here are highlights of the perspectives and best practices he shared.

Sastry is a technology evangelist with over 20 years of experience in architecting and building scalable distributed computing systems, in the areas of Application Servers, Java/J2EE/Web Services, SOA and Grid Computing. He is currently a Distinguished Architect at eBay, driving the SOA architecture and platform for the eBay ecommerce platform. Prior to joining eBay, Sastry was Co-Founder and CTO of OpenGridSolutions, Founding member and Architect at SpikeSource, and an Architect at Oracle. Sastry also worked at many other companies in the early stages of his career and holds a Masters degree from I.I.T, Kharagpur, India. Sastry has presented at many conferences including JavaOne, Oracle World, SOA world and IONA world to name a few. Sastry contributed to and represented in many standards at OMG, JCP, GGF and OASIS.

As the number of services and resources grow in an SOA deployment, the task of locating which service resides where is going to become tedious. Wrong or outdated endpoint configurations can lead to application faults, service outages and business revenue losses. WS-Discovery is a standard protocol for publishing and discovering service endpoints in a complex SOA. Using WS-Discovery, systems can automatically discover the services and endpoints they are interested in without any human intervention. In this article, Hiranya Jayathilaka provides a brief introduction to WS-Discovery and how this standard is supported by WSO2 Carbon based products such as WSO2 AS, WSO2 DSS, WSO2 GReg and WSO2 ESB.

This article describes a usecase which demonstrates how the WSO2 ESB can be used with BlackBerry client. You can also do many things inside this proxy service like calling actual Web services, mediate message, logging, message reformat etc.

This article is targeting enterprise architects who are building SOA-based solutions. It describes how generic patterns are mapped to WSO2 products for implementation.
