Knowledge Base

WSO2 Web Services Application Server is an open source service-based application server fully built on Apache Axis2 framework. It supports various Web services standards and protocols.

The information model within Axis2 contains a hierarchy of contexts. These contexts contain information about various levels within Axis2. Sometimes it is important to know when these contexts are created and removed. In this knowledge base item, we will discuss how we can get notified when new context is created and deleted.

If you try to look at the internals of Axis2 a little bit beyond the generated stubs, you will see the ServiceClient class. Let us look at what it means.

The Axis2/C architecture consists of flows, phases, modules and handlers.

WSO2 ESB can be deployed on differet application servers such as IBM WebSphere, BEA WebLogic Server, JBoss and Apache Tomcat. I will be describing how one can easily deploy WSO2 ESB on Apache Tomcat.

How to Serialize ADB Code Generated Objects

At times one needs to see the XML serialization of objects generated for various reasons. This knowledge base explains a simple method to serialize objects generated using the Axis2 Data Binding (ADB) frameowrk.

We generated code using wsdl2java tool, so that we can see the Web service methods as methods of a Java object. Once generated, we will be using these objects to send and receive parameters to/from the Web service that we are invoking. Take the following method as an example:
