Using Spring WebApplicationInitializer in karaf
I am trying the following code (replaces web.xml) in embedded Jetty 9.0.6 and
onStartup method is being invoked and the Spring context xml is being
loaded/parsed.
When I deploy in karaf 3.0.0 onStartup is not invoked. Any idea why? There
are no exceptions in the karaf log.
public class MyWebAppInitializer implements WebApplicationInitializer {
@Override
public void onStartup(ServletContext container) {
System.out.println("*************************** in onStartup()
*****************************");
XmlWebApplicationContext appContext = new XmlWebApplicationContext();
appContext.setConfigLocation("/WEB-INF/classes/workflow-ws-context.xml");
ServletRegistration.Dynamic dispatcher =
container.addServlet("dispatcher", new DispatcherServlet(appContext));
dispatcher.setLoadOnStartup(1);
dispatcher.addMapping("/");
}
}
"Implementations of this SPI will be detected automatically by
SpringServletContainerInitializer, which itself is bootstrapped
automatically by any Servlet 3.0 container. This class will be loaded and
instantiated and have its onStartup method invoked by any Servlet
3.0-compliant container during container startup assuming that the
spring-web module JAR is present on the classpath."

Just don't do it that way!
I think I've already given plenty of examples on how a web application is
supposed to look a like.
And this is definitely not the way I told you before.
So for one last time, get rid of those spring jars inside your web
application, deploy all spring bundles with the according feature that is
available with karaf.
Embedding jars in your bundle (yes, your war is just another bundle) should
be your last possibility and only if it is a really internal thing. Spring
definitely isn't an internal thing.
Make sure your Manifest does have the required Imports, if you fail in
generating all required Imports it is usually a good practice during
development to start with an dynamic-import. After that take a look of the
actual required imports, a bundle:header will help you with that, and get
back to your manifest where you just import the needed packages that you
just learned about.
And again, take a good look at the Spring-OSGi sample provided by Pax Web.
YOU WILL NEED Spring-DM to have Spring working.
Maybe it'll work if you switch from Aries-Blueprint to Gemini-Blueprint,
too. That I never tried before.
