public abstract class AbstractQi4jServletBootstrap extends Object implements javax.servlet.ServletContextListener, ApplicationAssembler
Application is set as a ServletContext attribute named using a constant.
In your servlets, filters, whatever has access to the ServletContext use the following code to get a
handle on the Application:
org.qi4j.api.structure.Application application; application = ( Application ) servletContext.getAttribute( Qi4jServletSupport.APP_IN_CTX ); // Or, shorter: application = Qi4jServletSupport.application( servletContext );Rembember that the servlet specification states: In cases where the container is distributed over many virtual machines, a Web application will have an instance of the ServletContext for each JVM. Context attributes are local to the JVM in which they were created. This prevents ServletContext attributes from being a shared memory store in a distributed container. When information needs to be shared between servlets running in a distributed environment, the information should be placed into a session, stored in a database, or set in an Enterprise JavaBeans component.
