Re: Blueprint XML for Camel JDBC component

Hi,

Ensure you already install camel-jdbc feature.
Btw, please don't cross-post same question multiple times, I just saw your same question in another thread.

Hello,
Please can someone help me with sample blueprint for Camel JDBC component, 
when I tried the below one, I am getting *NoSuchComponentException*

org.apache.camel.RuntimeCamelException:
org.osgi.service.blueprint.container.NoSuchComponentException: No component 
with id 'jdbc://dataSource' could be found

Please find the blueprint that I have used and advice where I am going
wrong.
