# Java EE 6 / EJB 3.1 / JSF 2.0 WAR Modularization With Maven - Concrete Sample

The backing bean HelloView:@ManagedBean@RequestScopedpublic class HelloView {    @EJB HelloService helloService;    public String getHelloMessage(){        return helloService.hello();    }} is packaged directly in the classes folder inside the Java EE 6 WAR. The boundary HelloService:@Statelesspublic class HelloService {    @EJB CurrentTimeService currentTimeService;    public String hello(){        return "Hello: " + currentTimeService.getCurrentDate();    }} Is located in the JAR-module with the following maven metadata:[...]   <groupId>com.abien.patterns.business</groupId>  <artifactId>ModularWarWithEJBsBoundary</artifactId>  <packaging>jar</packaging>  <version>1.0-SNAPSHOT</version>  <name>ModularWarWithEJBsBoundary</name>[...]  It references the CurrentTimeService control, @Statelesspublic class CurrentTimeService {    public Date getCurrentDate(){        return new Date();    }} which gets automatically injected. The CurrentTimeService resides in another module. The compile-scoped dependency is specified in the pom.xml:    <dependency>        <groupId>com.abien.patterns.business</groupId>        <artifactId>ModularWarWithEJBsControl</artifactId>        <version>1.0-SNAPSHOT</version>        <scope>compile</scope>    </dependency>All EJBs are located in standard JARs. There is no need for special treatment / artifacts.In the pom.xml of the WAR-project only the dependency to the boundary has to be specified. The transitive dependency to the control is automatically inherited:<groupId>com.abien.patterns.business</groupId>   <artifactId>ModularWarWithEJBs</artifactId>   <packaging>war</packaging>   <version>1.0-SNAPSHOT</version>   <name>ModularWarWithEJBs Java EE 6 Webapp</name>   <url>http://maven.apache.org</url>   <dependencies>      <dependency>         <groupId>com.abien.patterns.business</groupId>         <artifactId>ModularWarWithEJBsBoundary</artifactId>         <version>1.0-SNAPSHOT</version>         <scope>compile</scope>      </dependency>   </dependencies>[...] You will find both JAR-modules in the WEB-INF/lib/ folder:ModularWarWithEJBs/+--WEB-INF/+----lib/+------ModularWarWithEJBsBoundary-1.0-SNAPSHOT.jar +------ModularWarWithEJBsControl-1.0-SNAPSHOT.jar  Java EE 6 WAR is the "new" EAR - it allows easy packaging and pragmatic modularization of EJB-modules and web applications. Together with Maven it's the perfectly synergy.The working maven projects (ModularWarWithEJBs Java EE 6 Webapp) were pushed in into: http://kenai.com/projects/javaee-patterns/.
