我们正在运行JBoss 7.1.1 Final。我们运行Jgroup通道并通过它发送消息。在org.jgroups.Message中，我们设置了自定义对象，这些对象存在于我们耳中的lib中的jar中。 我们的耳朵依赖于名为pam的模块“Dependencies：pam”和pam模块添加jgroups的依赖
现在，当我们尝试发送和接收消息时，我们会遇到异常

目前为了解决这个问题，我们在我们耳中的lib中添加了jgroup jar。 有没有其他方法可以解决这种类型的序列化问题？
答案 0 :(得分：0)
org / jgroups / main模块的module.xml文件缺少依赖项，在本例中是包含GlobalDBNotification类的模块或.jar文件。添加缺少的依赖项，错误就会消失。
