Apart from this code, is spring and axis2 running together in your web
service? I thought you said it was. I think I know what your are
asking for, but without knowing what "TavernaBaseProfile" is doing,
I'd be concerned that it creates two separate Spring worlds in your
app - you probably don't want that. Anyways, with that caveat, if you
just need "ApplicationContext" to pass into "TavernaBaseProfile" , I
would do the following:
Keep axis2 and spring as is, since its working. The idea behind the
axis2 ApplicationContextHolder is a known way to get an
ApplicationContext, and can be used outside axis2. So I think you
should create your own. Its easy, and it seems far less confusing, at
least to me, to use your own ApplicationContextHolder outside of axis2
when using SpringServletContextObjectSupplier. So you'd need this xml
in your Spring config:
<!-- Use this trick to get access to Spring beans in junit and other places
that are not spring aware
-->
<bean id="applicationContext"
class="mypackage.spring.ApplicationContextHolder" />
And this class in your app:
package mypackage.spring;
import org.springframework.beans.BeansException;
import org.springframework.context.ApplicationContext;
import org.springframework.context.ApplicationContextAware;
/** Implementation of a Spring interface who is configured in Spring's
* applicationContext.xml or some other Spring type of way. This class
* and the spring bean needed to wire it could be used as an alternative
* to getting the ApplicationContext from the ServletContext. It also can
* be used to get access to spring beans in places like junit that are not
* spring aware.
*/
public class ApplicationContextHolder implements ApplicationContextAware {
private static ApplicationContext appCtx;
public ApplicationContextHolder() {}
/** Spring supplied interface method for injecting app context. */
public void setApplicationContext(ApplicationContext applicationContext)
throws BeansException {
appCtx = applicationContext;
}
/** Access to spring wired beans. */
public static ApplicationContext getContext() {
return appCtx;
}
}
Then instead of:
ApplicationContext context = new
RavenAwareClassPathXmlApplicationContext("context.xml");
Do this:
ApplicationContext ctx = ApplicationContextHolder.getContext();
TavernaBaseProfile profile = new TavernaBaseProfile(context);
Good luck,
Robert
