javax.naming.NameNotFoundException: bookingDatabase not bound

 在执行
InitialContext ctx1 = new InitialContext();
            emf = (EntityManagerFactory) ctx1.lookup("java:/bookingDatabase");
操作时出现以上错误。

参照
http://docs.jboss.com/seam/2.0.0.B1/reference/en/html/persistence.html#d0e5490
的解释，进行以下操作：

1、修改
components.xml
增加
    <core:managed-persistence-context
          name="bookingDatabase"
          auto-create="true"
          persistence-unit-jndi-name="java:/bookingDatabase"/>
         

2、修改
persistence.xml
增加

         <!-- by cbq -->    
         <property name="jboss.entity.manager.factory.jndi.name"
                   value="java:/bookingDatabase"/>
