Question

对于一个webapp项目，我使用Eclipse + Jax-RS Jersey 2.5 + JPA 2.0，在Eclipse上从Glassfish服务器上部署应用程序后，我遇到了一些奇怪的问题。

事实上，如果我点击“Run on server”，一切正常，让部署结束，然后重新启动Glassfish服务器;顺便说一句，它在开发时效果不是很好，因为它会浪费很多时间......

如果我只是点击“Run on server”，那么我的EJB都没有注入，导致NullPointerException阻止我做任何事情。

我使用Maven进行依赖管理，它可以来自它吗？我应该使用“运行在服务器上”之外的其他方式在代码更改后重新部署我的应用程序吗？

由于

编辑：这是该项目的架构：

src/
    main/
        java/
            /* Application packages */
        resources/
            META-INF/
                persistence.xml
        webapp/
            WEB(INF/
                beans.xml
            /* App templates */
pom.xml

编辑2：

即使使用此脚本也不起作用：

/opt/apache-maven-3.1.1/bin/mvn clean package
/opt/glassfish4/glassfish/bin/asadmin --host localhost --port 4848 --user admin --passwordfile /opt/glassfish4/glassfish/domains/domain1/config/admin-keyfile --interactive=false --echo=true --terse=false undeploy --keepreposdir=true --isredeploy=false --cascade=false --_ignorecascade=false --_classicstyle=false configurator
/opt/glassfish4/glassfish/bin/asadmin --host localhost --port 4848 --user admin --passwordfile /opt/glassfish4/glassfish/domains/domain1/config/admin-keyfile --interactive=false --echo=true --terse=false deploy --name configurator --force=false --precompilejsp=false --verify=false --generatermistubs=false --availabilityenabled=false --asyncreplication=true --keepreposdir=true --keepfailedstubs=false --isredeploy=false --logreportederrors=true --_classicstyle=false --upload=false /home/jeremy/workspace-configurator-v2/trunk/configurator/target/configurator.war

EJB注入了EJB注释，并指定了LOOKUP名称：

@EJB( name=CustomApplicationService.LOOKUP_NAME )
private CustomApplicationService customApplicationService;

班级：

@Stateless
public class CustomApplicationService {

public final static String LOOKUP_NAME = "java:global/configurator/CustomApplicationService";

    @PersistenceContext( name=UtilConsts.DATABASE_POOL )
    private EntityManager em;
       /**** */
}

最后，我的pom.xml：
