Take a look at conf/jndi.xml in your ServiceMix distribution.
You will find examples of configuring stuff in JNDI.

Hi gnodet,
I read the blog, can you please elobarate where and how to configure the
Data base url,username, password inside the servicemix?
You have given the jndiName as follows
<property name="jndiName" value="java:myDataBase" />
but where is the myDataBase configured?
One more general question, Is it the right way of putting business
logic inside ESB?
