我目前在使用带有portlet插件的struts2在集群环境中实现jsr 168 portlet时遇到问题。每当我使用模型驱动的界面并提交表单时，我都会收到以下堆栈跟踪：

用于复制问题的示例程序git：//github.com/ctwomey1/Struts2PortletExample.git
我在运行pluto 1.1.7的tomcat 6.0.33中复制了这个问题。我在struts 2.1.3.2和2.3.3
上尝试了这个如果有人看到我做错了什么我会喜欢建议：）
更新：我已将此记录为struts2 portlet插件的问题。我正在定期研究解决方案
答案 0 :(得分：0)
不幸的是，这看起来像Struts 2中的已知错误。要重现该错误，您需要一个Struts操作，并将List作为参数，然后在尝试序列化此列表时收到此堆栈跟踪（因为它不是序列化）。完整的错误报告可以在这里找到：
