There are two separate things.
1) Spring provides two subclasses of AbstractXmlApplicationContext [1] to
handle the file-based locations and classpath-based locations.
2) Tuscany implementation.spring uses locations either as absolute URLs or
relative to contributions
IMO, we should subclass AbstractXmlApplicationContext and provide a
ResourcePatternResolver [2] to create UrlResource [3] to support our
location schemes.

Subject: [DISCUSS] Supporting files outside the contribution for
implementation.spring
Implementation Spring supports handling of multiple application contexts
using ClassPathXmlApplicationContext
and FileSystemXmlApplicationContext.
ClassPathXmlApplicationContext looks good as it accepts the path to files
relative to the contribution, but there
seems to be an issue while dealing with FileSystemXmlApplicationContext, as
the relative path to the contribution is not
accepted by spring (as per design), instead it expects a path relative to
the current VM working directory.
To be specific, the path expected by spring runtime is shown below....
<bean id="beanRefFactory"
class="org.springframework.context.support.FileSystemXmlApplicationContext">
<constructor-arg>
<list>
<value>/src/main/resources/beanRef-SpringHelloWorld-context.xml</value>
<value>/src/main/resources/bean-frontend-springimpl-context.xml</value>
</list>
</constructor-arg>
</bean>
In such cases, Tuscany classloaders are unable to see the files are they are
out of the contribution and also
possibly out of the classloaders visibility.
Should we support any files outside the contribution OR can Tuscany support
such usecases?
