What is the correct camel's schemaLocation?
Hi,
I'm bit confused regarding the schemaLocation both by camel as well as
spring.
Reading at [1] it says:
/
You need to add Camel to the schemaLocation declaration
http://camel.apache.org/schema/spring
http://camel.apache.org/schema/spring/camel-spring.xsd
/
But as an example if I'm riding on camel 2.8.0 shouldn't I correctly use the
following schemaLocation declaration instead:
/http://camel.apache.org/schema/spring
http://camel.apache.org/schema/spring/camel-spring-2.8.0.xsd
/
As for example the complex type "keyManagersParametersFactoryBean" is first
introduced by camel 2.8.0 (see [2]), and if I would make a usage of it in my
spring-xml-configuration, how should that type be resolved / checked at
runtime through the xml validating parser (via spring ApplicationContext
initialization)?
On the other hand spring documentation itself at [3] says that
/The 'xsi:schemaLocation' fragment is not actually required...
/
So my question is how the schemaLocation magic really works at runtime in
general, for example as the SAX-Validating-Parser goes over it while the
spring initialization happens through the ClassPathXmlApplicationContext
initialization / instantiation?

Just for the case other camel user's are interested as well, following the
explanation of that "schemaLocation-magic":
http://static.springsource.org/spring/docs/3.0.x/spring-framework-reference/html/extensible-xml.html#extensible-xml-registration-spring-schemas
Thanks Freeman for making this clear to me

Hi again Freeman,
My last question by my previous post was simply stupid, please ignore it.
The mapping happens always through META-INF/spring.schemas both by spring as
well as camel itself.
Thanks for your clarification

Hi Freeman,
thanks for your reply, now I see, indeed the camel-spring.xsd &
camel-spring-v2.8.xsd are both there:
http://repo1.maven.org/maven2/org/apache/camel/camel-spring/2.8.0/camel-spring-2.8.0.jar
looking at spring itself, it seems it is done in a similar fashion:
http://repo1.maven.org/maven2/org/springframework/spring-beans/3.0.5.RELEASE/spring-beans-3.0.5.RELEASE.jar
that's the file META-INF/spring.schemas which maps each given namespace to
the corresponding xsd file inside jar itself, like the following entry
inside META-INF/spring.schemas:
http\://www.springframework.org/schema/beans/spring-beans.xsd=org/springframework/beans/factory/xml/spring-beans-3.0.xsd
just as the last question, as I'm curious and in the case you know it
already, do you know where exactly in camel-spring's code that "mapping
magic" happens?
Regards, Babak

Hi,
The magic is the spring.schemas inside camel-spring.jar, it always map
the namespace to the local camel-spring.xsd inside camel-spring.jar,
so that both http://camel.apache.org/schema/spring/camel-spring.xsd
and http://camel.apache.org/schema/spring/camel-spring-2.8.0.xsd works
here, but use http://camel.apache.org/schema/spring/camel-spring.xsd
is better as you needn't change your router configuration file when
camel version changes.
