Invalid ejb jar: it contains zero ejb.
I have 2 modules: ejb and war, and ear module, that contains them. Modules build successfully, but when I try to deploy ear to glassfish, I recieve this error:
glassfish3.1.2|javax.enterprise.system.tools.admin.org.glassfish.deployment.admin|_ThreadID=17;_ThreadName=Thread-2;|Exception while deploying the app [EarModule] : Invalid ejb jar [BackEnd-1.0-SNAPSHOT.jar]: it contains zero ejb.
Note:
1. A valid ejb jar requires at least one session, entity (1.x/2.x style), or message-driven bean.
2. EJB3+ entity beans (@Entity) are POJOs and please package them as library jar.
3. If the jar file contains valid EJBs which are annotated with EJB component level annotations (@Stateless, @Stateful, @MessageDriven, @Singleton), please check server.log to see whether the annotations were processed properly.|#]
I really don't know what to do, I've found a lot of questions like mine, but there was no solution.
Answer
I understood, what was wrong. The problem was in run configurations, I'm using Intellij Idea and in run configurations there was build and make before run of my ear module. I removed this and after maven install it deployed successfully.
