当我尝试部署到新创建的managedServer（它应用了JRF）时，遇到了一个异常。当应用程序想要使用org/apache/myfaces/trinidad/model/ChildPropertyTreeModel类时，出现以下异常。它曾经在WC_Spaces上正常运行。即使我将trinidad-api、trinidad-api-impl.jar库复制到domainhome/lib文件夹中，也没有任何变化。
原因可能是什么？

我有一个自定义类扩展了ChildPropertyTreeModel并实现了Serializable。我已经用SerializedTreeModel进行了序列化。而这个类是在另一个项目（结构）中的另一个单词war部署包的web-inf/lib已经包含了这个类。在我用refered项目将SerializedTreeModel类位置替换到同一个包中后，最终解决了问题。老实说，我无法理解这种魔力。
public class SerializedTreeModel extends ChildPropertyTreeModel implements Serializable
{
public SerializedTreeModel(Object dataList, String dataChild)
{
super(dataList, dataChild);
}
}
