场景:1)创建maven ear项目,在里面创建war项目2)将beans.xml添加到war项目的WEB-INF/ 3)创建简单的@Steateless bean
项目 - http://drp.ly/1j5C3t
ejb 豆:
@Stateless
@LocalBean
public class TestEjb {
@Inject
Logger log;
public TestEjb() {
}
@Schedule(hour = "*", minute = "*", second = "*/15")
public void print1Partner() {
log.info("Yrjaaaa");
System.out.println("This is test");
}
}

目标:我想在包含其他战争和 ejb 项目的耳朵档案内的 web 项目中使用 ejb 焊接(CDI),但我不希望分离我的 web 项目(战争 + ejb)
工具和环境:maven & ejb 3.1 &weld & glassfish 3.0.1
Q1:这可能是某种特定的玻璃鱼虫吗?Q2:什么可能是问题的原因?Q3:这种情况有什么设计吗?
谢谢你。
