java.lang.Object javaclients.HelloWorldMime
public class HelloWorldMime
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.
We use java client helper classes to generate the raw xml strings, e.g.:
PublishKey pk = new PublishKey(glob, "HelloWorldMime", "text/xml"); generates: <key oid='HelloWorldMime' contentMime='text/xml'/>Invoke: java javaclients.HelloWorldMime
Invoke: java javaclients.HelloWorldMime -session.name joe -passwd secret

I_Callback
So you should implement in your client code the I_Callback interface - suppling the update() method where you can do with the message whatever you want.
The raw protocol driver specific update() method (e.g. CORBA-BlasterCallback.update()) is unpacked and for each arrived message this update is called.
update
in interface I_Callback
cbSessionId
- The session ID specified by the client which registered the callback.
You can specify a cbSessionId during connection (with ConnectQos)
and this is bounced back here so you can authenticate the message.updateKey
- The arrived key containing the topic namecontent
- The arrived message content. This is your payload.I_XmlBlasterAccess
