Camel SQL Component & dataSource property

Hi

Reading http://activemq.apache.org/camel/sql-component.html I cannot
understand where I have to set the dataSource. I got

SEVERE: Failed: org.apache.camel.ResolveEndpointFailedException: Failed to
resolve endpoint: sql:select username as userid from mdl_user due to:
java.lang.IllegalArgumentException: Property 'dataSource' is required
org.apache.camel.ResolveEndpointFailedException: Failed to resolve endpoint:
sql:select username as userid from mdl_user due to:
java.lang.IllegalArgumentException: Property 'dataSource' is required

with 

<route>
	<from uri="timer://pollTheDatabase?delay=10000" />
	<setProperty propertyName="dataSource">
		<constant>moodleDB</constant>
	</setProperty>
	<to uri="sql:select username as userid from mdl_user" />
</route>

and with

<route>
	<from uri="timer://pollTheDatabase?delay=10000" />
	<to uri="sql:select username as userid from
mdl_user?template.dataSource=moodleDB" />
</route>

where moodleDB is defined as

	<bean id="moodleDB"
		class="org.springframework.jdbc.datasource.DriverManagerDataSource">
		<property name="driverClassName" value="com.mysql.jdbc.Driver" />
		<property name="url" value="jdbc:mysql://localhost:3306/moodle" />
		<property name="username" value="moodle" />
		<property name="password" value="moodle" />
	</bean>


It would be nice to have an example for each camel component in "examples"
in the camel distribution...

Thanks in advance
Matteo

Hello!

I've just added the information to the wiki page. Hope it will help :)

RE: Camel SQL Component & dataSource property

Hi

Yes this one needs improved documentation. It is a good idea to check the unit test in Camel how we test the component itself.

You can configure the component in Spring XML as a standard Spring Bean where you can set the properties. I guess it has a flaw in the URI so you can set a ref to a datasource nice and easily from Spring DSL as well.

Something like this, its standard Spring stuff:

<bean id="sql" class="org.apache....SqlComponent"/>
   <property name="dataSource" ref="myDataSource"/>
</bean>
