/**
* This client connects to xmlBlaster and invokes all available methods, further we
* show how to do a full text message filtering by looking into the xml message content
* and filter with XPath.
* <p />
* We use java client helper classes to generate the raw xml strings, e.g.:
* <pre>
* PublishKey pk = new PublishKey(glob, "HelloWorldMime", "text/xml");
*
* generates:
*
* <key oid='HelloWorldMime' contentMime='text/xml'/>
* </pre>
*
* Invoke: java javaclients.HelloWorldMime

* Invoke: java javaclients.HelloWorldMime -session.name joe -passwd secret
