This module has a classpath defined "applicationContext":http://redmine.z2-environment.net/projects/z2-samples/repository/z2-samples-spring-basic/revisions/master/entry/com.zfabrik.samples.spring-basic.services/java/src.impl/META-INF/applicationContext.xml and exposes an annotation defined bean "ComputationServiceImpl":http://redmine.z2-environment.net/projects/z2-samples/repository/z2-samples-spring-basic/revisions/master/entry/com.zfabrik.samples.spring-basic.services/java/src.impl/com/zfabrik/samples/impl/services/ComputationServiceImpl.java bean from it as a service to be consumed from another module: The *computations* bean.

This module has a Web application with an application context defined in WEB-INF/applicationContext. It uses Spring AspectJ based annotation driven configuration to inject dependencies into instances of "ControllerServlet":http://redmine.z2-environment.net/projects/z2-samples/repository/z2-samples-spring-basic/revisions/master/entry/com.zfabrik.samples.spring-basic.frontend/java/src.impl/com/zfabrik/samples/impl/frontend/ControllerServlet.java.
