/**
* Services soap requests to JAX-WS Spring beans found in system/pentahoServices.spring.xml
*
* This class is a workaround since we cannot figure out how to lazily init the ws- and wss- namespaced beans.
* Possibly related bug: https://issues.apache.org/jira/browse/XBEAN-97 (The ws and wss use XBean.)
*
* If the beans could be lazily initialized, then we could replace this servlet with
* <a href="https://jax-ws-commons.dev.java.net/spring/">com.sun.xml.ws.transport.http.servlet.WSSpringServlet</a>.
