Rampart is the Apache Axis2 module that implements the WS-Security features. To add such features to your Web service, Axis2 provides two different configuration mechanisms. One depends on WS-SecurityPolicy and is the approach that is preferred. The other approach is known as the “parameter based configuration”.

Many XML validators exist. Here's how you may implement an XML validator in Java. At times you may need to take a programmatic approach like this.

Environment: JDK 1.6, JBoss 5.1, Eclipse 3.5 (Galileo)

I came across the following JBoss error when a JAX-WS Web service was accessed:

11:15:18,008 ERROR [SOAPFaultHelperJAXWS] SOAP request exception
java.lang.UnsupportedOperationException: setProperty must be overridden by all subclasses of SOAPMessage

I could see possibly a bug related with coding in war distribution. And in both distributions, I could see improper axis2.xml files and several mistakes in packaging jars. Here's how you go about enabling clustering support:
