************************************WARNING*************************************
To use JAX-WS 2.1 with JDK 6, newer versions of API jars need to be in bootclasspath
before rt.jar. To do this you can use Java endorsed mechanism to override what is in
Java platform. The easiest way to do so is to put JAX-WS 2.1 and JAXB 2.1 API jars to
C:\Program Files (x86)\Apache Software Foundation\Apache Tomcat 7.0.22\endorsed folder.
