通过 JNDI 查找 Websphere ConnectionFactory 时出现 ClassCastException
ClassCastException while looking up Websphere ConnectionFactory via JNDI
我收到以下 class-cast 异常。
这可能是因为我的应用程序正在使用 JMS 2.0 API 而 Websphere 8.5.x 是 returning JMS v1.x 兼容对象
是Websphere 8.5.x限制吗？我可以在 Websphere and/or 应用程序上更改什么，以便它既 return / 使用 javax.jms.ConnectionFactory 对象？
Caused by: java.lang.ClassCastException: com.ibm.ejs.jms.JMSConnectionFactoryHandle incompatible with javax.jms.ConnectionFactory
at com.mypackage.myclass.MyConfig.getConnectionFactory(MyConfig.java:152)
Websphere 建议使用 javax.jms.ConnectionFactory 对象，我已经在使用它但仍然出现上述异常。
