从Weblogic迁移到tomcat问题

Question

我正在将应用程序从WebLogic迁移到Tomcat。

我知道Tomcat无法处理EJB代码，而这些代码是在WebLogic上部署项目时添加到项目中的。

因此，最终可以使用TomEE（1.7.2）服务器来帮助处理EJB代码。

但在TomEE Server错误下运行该项目同样出现，

java.lang.ClassCastException: org.apache.tomee.jdbc.TomEEDataSourceCreator$TomEEDataSource cannot be cast to org.omg.CORBA.Object

我的TomEE Server的Server.xml包含以下代码，

<Resource name="abc/myjndiName" auth="Container"
    type="javax.sql.DataSource" 
    driverClassName="oracle.jdbc.OracleDriver"
    factory="org.apache.openejb.core.LocalInitialContextFactory"
    url="jdbc:oracle:thin:@(DESCRIPTION =(ADDRESS_LIST 
    =(ADDRESS = (PROTOCOL = TCP)(HOST = hostname.com)(PORT = 1111))
     (ADDRESS = (PROTOCOL = TCP)(HOST = hostname.com)(PORT = 1111))
     (LOAD_BALANCE = yes))(CONNECT_DATA =(SERVICE_NAME = hostname.com)))"
      user="XXX" password="XXX"
      maxActive="20" maxIdle="10" maxWait="10000" />

任何人都可以解决它吗？出了什么问题？ 那将是一种欣赏。

感谢。

错误的全栈跟踪看起来同样如此，
