我在从MQ消费时反序列化消息时遇到问题。该应用程序部署在weblogic上，并通过weblogic外部服务器配置连接到MQ。消息的内容是一个Spring集成框架类（ChunkRequest），我确保所有相关的库都在接收方的weblogic类路径中。在接收方，我得到一个ClassNotFoundException。
为了更加确定，我已将相关库添加到weblogic库和应用程序中，没有太多运气。所需的类也会添加到<prefer-application-packages>中的weblogic-application.xml。任何指针都将非常感激。
感谢

答案 0 :(得分：0)
嗯，听起来你没有在CLASSPATH中包含所有必需的MQ JAR文件。
对于使用MQ 7.5.0。*的应用程序，列表为：
对于使用MQ 8.0.0。*的应用程序，列表是（推荐方法）：
或者对于旧学校的MQers，使用MQ 8.0.0。*的应用程序，列表是：
