My project needs to provide read and write access to data using web services (SOAP/JSON etc), but we also need the ability to serve real-time notifications of data changes to external users through websockets. Does WSO2's ESB support this capability?
AFAIK, currently no support for websockets..but, you could write data to websockets using classmediators

My problem now resides more on understand my configuration than what i have done with the data.
Kind Regards.
See Wire-Tap pattern and Logging Channel Adapter.
The first one will let to to track a message journey through you flow and the second one will let you to configure whatever you want to log with its logExpression option.

Is it a good idea to use a message queue as websocket server in production (instead of Java EE #ServerEndpoint)?
It would establish a loose coupling towards the JS client and perhaps reduce the load from the application, but are there major disadvantages? Should one really expose a MQ over the web?
One can send messages to websocket clients from within a java web application without the help of a message queue. And this is a good enough solution as long as you do not need the additional features that message queues have to offer (QoS 1/2, Retained messages, Last Will and Testament, ... for some more benefits of using a mq see for example: http://www.hivemq.com/mqtt-over-websockets-with-hivemq/)

I would like to use "Spring Session" in my current project, but it seems that currently only Redis is a supported backend database. The official documentation is not talking about any other support yet.
Are there alternative implementations for other databases? For example, what about Memcached or Couchbase Support, which are fast Key-/Value Stores as well?
AFAIK only redis and hazelcast is supported but maybe you can find some 3rd party. Or you might want to implement it by yourself (and make it open source). It does not seems to be that complicated - see
https://github.com/spring-projects/spring-session/blob/1.0.1.RELEASE/samples/hazelcast/src/main/java/sample/Initializer.java
It looks like you just need to implement your SessionRepository and use proper HTTP filter.

I want to write a program that displays the monitoring data that you see on the Azure management portal.
The program should monitor Website and not storage or web/worker role
can Windows Azure API provide access to all the data that is exposed on the portal??
Please suggest how can I get started with this. Should I consider converting website to worker role?
Forgive me for the lame question as I am very new to Azure and Cloud
I don't believe the Windows Azure Website monitoring data is publically exposed at this time. Maybe once the service GA's?
If you want detailed metrics (performance counters), then you'll need to use a web/worker role.
