JMS Server - Web Server

Question

Hi folks,
I want to use JMS in my CEP application. And I do not know where should i start. Documentation I think is not enough. What is your suggestion?
Should I install an extra web server to handle JMS queue or can Oracle CEP server handle it?
In addition, if some application use my web service written in java, will I have to installed an web server?
I am using Oracle 11.1.1.3.
Thanks.

Hi alexalves,
I downloaded application you mentioned. When i deploying, it successfully deployed but could not start. It says instance-propery tag must have value or ref attribute. I checked assembly file but i could not find any miss point. Error :
