Camel-OSGI and namespaces

When Spring DSL is used to define camelContext, route, ... in an OSGI
bundle, the following namespaces and schema location must be used :

<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xmlns:camel="http://camel.apache.org/schema/osgi"
       xsi:schemaLocation="
       http://www.springframework.org/schema/beans
       http://www.springframework.org/schema/beans/spring-beans-2.5.xsd
       http://camel.apache.org/schema/osgi
       http://camel.apache.org/schema/osgi/camel-osgi.xsd
    ">

For info, the camel-osgi.xsd schema imports well camel-spring.xsd

<xs:schema elementFormDefault="qualified" version="1.0"
           targetNamespace="http://camel.apache.org/schema/osgi"
           xmlns:tns="http://camel.apache.org/schema/osgi"
           xmlns:camel="http://camel.apache.org/schema/spring"
           xmlns:xs="http://www.w3.org/2001/XMLSchema">

  <xs:import namespace="http://camel.apache.org/schema/spring"
             schemaLocation="http://camel.apache.org/schema/spring/camel-spring.xsd"
/>


What is going wrong is that when the camelContext is defined like this

	<!-- Camel context -->	
	<camel:camelContext id="common" trace="false">

		<jmxAgent id="agent" createConnector="false"/>

        </camel:camelContext>

the XML parser generates this error

Caused by: org.xml.sax.SAXParseException: cvc-complex-type.2.4.a:

"http://camel.apache.org/schema/spring":route}' is expected.

Thx.

It should be interesting to mention it in the wiki page :

Re: Camel-OSGI and namespaces

Posted by Willem Jiang <wi...@gmail.com>.

Hi Charles,

The right Camel context should be
         <!-- Camel context -->	
	<camel:camelContext id="common" trace="false">

		<camel:jmxAgent id="agent" createConnector="false"/>

         </camel:camelContext>

If you don't want to add the namespace prefix you need to define the 
default namespace at root element like this
         <!-- Camel context -->	
	<camelContext id="common" trace="false" 
xmlns="http://camel.apache.org/schema/spring">

		<jmxAgent id="agent" createConnector="false"/>

         </camelContext>
