  - generateConversationId
```
String generateConversationId()
```
    Generate a new conversation Id which is unique for a certain session. We need to do this via a pluggable Service as it makes a huge difference whether the id has to be unique on a single JVM or on multiple of them. If we have a ServletSession then we only have to be unique per Session and thus can make the handling much easier.
