使用本地EJB,在同一个容器中但不同耳朵

我试图在同一个Glassfish中使用本地EJB,但使用不同的耳朵。 但Glassfish无法找到本地EJB或无法使用

我读到: 根据JavaEE教程,@Local bean的客户端“必须与它访问的企业bean在同一个JVM中运行。”

在第一个耳朵里 ,我有一个罐子里的本地接口

@Local
public interface MyLocalBean {
  int getNumber(int num3);
} 

在另一个jar中,我有这个实现

@Stateless
@LocalBean
public class MyLocalBeanImpl implements MyLocalBean,Serializable{
     public MyLocalBeanImpl() {}
     public int getNumber(int num3){......

在第二只耳朵里 ,在同一个Glassfish里

我有一个jar里面的本地接口

@Local
public interface MyLocalBean {
int getNumber(int num3);
 } 

在另一个罐子里,我有消费者

@Stateless
@LocalBean
public class BeanConsumer{
@EJB(name="MyLocalBeanImpl")
private MyLocalBean beanlocal;

与@EJB和(name =“MyLocalBeanImpl”)参数的错误是:

Cannot resolve reference Local ejb-ref name=MyLocalBeanImpl,Local 3.x 
interface =my.package.MyLocalBean,ejb-link=null,lookup=,
mappedName=,jndi-name=,refType=Session|#]

与@EJB和(name =“my.package.MyLocalBeanImpl”)参数的错误是:

Cannot resolve reference Local ejb-ref name=my.package.MyLocalBeanImpl,
Local 3.x interface =my.package.MyLocalBean,ejb-link=null,
lookup=,mappedName=,jndi-name=,refType=Session|#]***

我也尝试过使用mappedName

    @Stateless(name="MyLocalBeanImpl",mappedName ="MyLocalBeanImpl")
    public class MyLocalBeanImpl implements MyLocalBean{

@EJB(name="MyLocalBeanImpl",mappedName ="MyLocalBeanImpl")
private MyLocalBean beanlocal;

但错误仍然存​​在

 Cannot resolve reference Local ejb-ref name=MyLocalBeanImpl,
 Local 3.x interface =my.package.MyLocalBean,ejb-link=null,
 lookup=,mappedName=MyLocalBeanImpl,jndi-name=,refType=Session

GlassFish与JNDI一起工作

 java:global[/<app-name>]/<module-name>/<bean-name>

我将注释@LocalBean添加到Bean MyLocalBeanImpl

@Stateless
@LocalBean
public class MyLocalBeanImpl implements MyLocalBean{
     public MyLocalBeanImpl() {}
     public int getNumber(int num3){......

当我部署Glassfish时,说jndi是两个

  Portable JNDI names for EJB OtroBean
  java:global/myfirstear/myejbs/MyLocalBeanImpl!my.package.MyLocalBeanImpl  
  and
  java:global/myfirstear/myejbs/MyLocalBeanImpl!my.package.MyLocalBean

我正在尝试

 @EJB(lookup="java:global/myfirstear/myejbs/MyLocalBeanImpl!my.package.MyLocalBeanImpl")

Glassfish似乎发现了Local Bean,但是... Glassfish在铸造类似这样的东西时遇到了问题

 javax.naming.NamingException
 javax.ejb.EJBException: javax.ejb.CreateException: Could not create stateless EJB
 at     
 com.sun.ejb.containers.StatelessSessionContainer
 ._getContext(StatelessSessionContainer.java:454)
 .....
 Caused by: javax.ejb.EJBException: 
 javax.ejb.CreateException: Could not create stateless EJB
 ....
 Caused by: com.sun.enterprise.container.common.spi.util.InjectionException:

 lookup=java:global/myfirstear/myejbs/MyLocalBeanImpl!my.package.MyLocalBeanImpl,
 mappedName=,jndi-name=,refType=Session into class my.package.BeanConsumer: 
 Can not set my.package.MyLocalBean field my.package.BeanConsumer.beanlocal 
 to   my.package.beans.__EJB31_Generated__MyLocalBeanImpl__Intf____Bean__

并尝试着

 @EJB(lookup="java:global/myfirstear/myejbs/MyLocalBeanImpl")

我得到:

throws javax.naming.NamingException
 javax.ejb.EJBException: javax.ejb.EJBException: javax.ejb.CreateException: Could not create stateless EJB

 Caused by: com.sun.enterprise.container.common.spi.util.InjectionException:

 into class  my.package.BeanConsumer:

 java.naming.factory.url.pkgs=
 com.sun.enterprise.naming}

可以将本地EJB注入到同一个JVM中的另一个EJB中,但不同的耳朵。

问题是你不能再依赖于bean的名字,因为你需要告诉consumer bean完整的JNDI名称。 您可以在部署期间在服务器日志中找到该名称; 当bean绑定到JNDI目录时,服务器在日志中显示它。
