I think what Raymond is trying to say is that, if we use 2), then existent SCA mechanisms could easily accomplish what you want, you could use resource import/export in sca-contribution.xml file to easily allow you to import spring contexts from other contributions. If you are looking to support this in 2.x, then we might need to check if contribution-resource is already ported to that code stream. > Thanks, > Raymond > > From: Ramkumar R > Sent: Thursday, June 18, 2009 3:40 AM > To: [email protected] > 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? > > -- > Thanks & Regards, > Ramkumar Ramalingam > -- Luciano Resende Apache Tuscany, Apache PhotArk http://people.apache.org/~lresende http://lresende.blogspot.com/
