The WSO2 WSAS clustering implementation supports state replication across a cluster of nodes. The objects that have to be replicated should be serializable, and should be placed in the Axis2 context hierarchy. However, there are situations in which we should refrain from replicating some objects. This tutorial by Afkham Azeez takes a look at how this can be done at system level, and at the level of different Axis2 contexts.

WSO2 Web Services Application Server (WSAS) allows Web services developers to easily expose, configure and manage any type of Java application as a Web service and Web services related artifact. WSO2 WSAS now comes with the Eclipse WTP Integration which enables the Web service developer to easily work within their favorite IDE on all their Web services requirements covering the full cycle of development, deployment, testing and debugging.

The Web Services Metadata Exchange specification describes a standard way to encapsulate services metadata and a protocol to retrieve it. It allows the client to interact with the service automatically, fetch all relevant metadata and aids the client in self-configuring.

Kyle Gabhart in his article on O'Reilly XML.com introduces WSO2 Data Services, a new feature available in WSO2's WSAS 2.0 platform,  (the latest release being version 2.1). He will begin by introducing Data Services, examining their architecture and utilization, and then exploring pros and cons of this convenient feature.
