Question

I have a an ear file to be deployed on weblogic 12c.

I have following project structure :
1) prop-application which is an .ear file
2) prop-service which is a .jar file
3) prop-framework which is a .jar file

All are maven project. 
 - prop-service contains prop-framework as one of its maven dependency. 
 - prop-application which is an ear contains prop-service

so we can say : prop-application.ear = prop-service.jar + prop-framework.jar
                prop-service.jar = more java codes + prop-framework.jar

Now there is a class in prop-framework as :

@Stateless(name = "ServiceCallerBean")
public class ServiceCallerBean implements ServiceCaller

@Local
public interface ServiceCaller

Requirement :
Now i want to lookup(call) this EJB from a from a class in *prop-service* i.e a local look. The point here is to note that prop-service.jar contains prop-framework.jar

Following is the jndi names generated by weblogic 12c server :
java:global/ProposalEngine/prop-service-0.0.1-SNAPSHOT/ServiceCallerBean.> 
java:module/ServiceCallerBean.> 
java:app/prop-service-0.0.1-SNAPSHOT/ServiceCallerBean.> 
java:global/ProposalEngine/prop-service-0.0.1-SNAPSHOT/ServiceCallerBean!com.db.serviceframework.ejb.ServiceCaller.> 
java:app/prop-service-0.0.1-SNAPSHOT/ServiceCallerBean!com.db.serviceframework.ejb.ServiceCaller.> 
java:module/ServiceCallerBean!com.db.serviceframework.ejb.ServiceCaller.> 

I can't use those jndi names which contains jar version(eg 0.0.1-SNAPSHOT) because jar version will keep on changing. But if i use any of the jndi names like java:module/ServiceCallerBean , then there lookup fails with javax.naming.NameNotFoundException: While trying to lookup error

I have tried even :
@EJB
ServiceCaller serviceCaller

在prop-service中的必需类中，但serviceCaller在这里是null。搜索了这个问题，发现我们只能在容器托管类中使用@EJB，而不是简单的java类。

我已经尝试了一切，但注意到似乎工作。所以PLZ帮我解决了这个问题。

This blog包含对JNDI地址来自何处的很好的解释。 prop-service-0.0.1-SNAPSHOT条目取自JAR或WAR的名称，因此您可以使用Maven JAR插件更改JAR的final name，您应该能够删除版本号{{3 }}
