SpringMVC V4 + Karaf

[Tim Jones <ti...@mccarthy.co.nz>]

Hi,

I am looking for a solution for integrating a war based upon SpringMVC V4+
with Karaf/Jetty. Currently we have a working web app based upon
SpringMVC/Security/Mobile V3 that uses SpringDM running on Karaf 2.3.2. We
would like to continue with Spring but upgrade to version 4.

I was wondering if perhaps Achim with your pax-web experience or others had
any thoughts on the following approach. By instructing the
maven-bundle-plugin to use <Spring-Context> instead of <Bundle-Blueprint>
then the blueprint-spring-extender
(https://github.com/apache/aries/tree/trunk/blueprint/blueprint-spring-extender,
thanks Guillaume) would be used to process the Spring namespaced config file
e.g

<plugin>
   <groupId>org.apache.felix</groupId>
    <artifactId>maven-bundle-plugin</artifactId>
    <configuration>
       <instructions>
          <Spring-Context>WEB-INF/track-trace-servlet.xml</Spring-Context>   

This much I have done and I can log the Spring beans in the application
context and the osgi services to the Karaf console.

However the Spring DispatcherServlet still needs to be registered and I
thought that this could perhaps be achieved by programmatically implementing
Springs WebApplicationInitializer
(http://docs.spring.io/spring/docs/current/javadoc-api/org/springframework/web/WebApplicationInitializer.html).
Assuming that the servlet container was able to find the class implementing
the WebApplicationInitializer would this be sufficient? If so, any pointers
on how to coax the servlet container to scan and find the customised
WebApplicationInitializer? 

Thanks,

Tim

Hi Tim,

Did you had any success following this approach?

Hi Tim,

sounds like a good approach. The custom WebApplicationInitializer should be
instantiated by the War Extender as it's a
regular ServletContainerInitializer.
An OutOfTheBox solution for this isn't available yet, but maybe it can be
generalized and either be provided by Karaf/Aries or Pax-Web :D

regards, Achim
