我在websphere门户环境版本6.1中运行基于JSF的portlet时遇到异常。

我的portlet扩展了FacesGenericPortlet，并有一个简单的doView（）方法。
有没有人经历过这种例外？
是的，我在jsf-portlet.jar旁边使用了以下的jar（而不是jsf-portletbridge.jar）
提前致谢。
答案 0 :(得分：1)
我不确定您使用的是什么版本的RAD，但如果您使用的是7或更高版本，建议使用更新的jsf portlet桥接库。
根据http://www-01.ibm.com/support/docview.wss?uid=swg21307687（记录与portlet桥相关的不同问题）：
com.ibm.faces.webapp.FacesGenericPortlet类是用作RAD v6.0 JSF portlet的基类的portlet类。
在RAD v7.0中，portlet桥可以更好地处理浏览器后退按钮问题，并在不使用会话的情况下在操作之间传递信息以呈现阶段。因此，新的.jar文件jsf-portletbridge.jar将替换旧的RAD v6.0 portlet桥jsf-portlet.jar。
当使用新的.jar文件jsf-portletbridge.jar时，会出现此特殊问题，但未按照V6.0.x中的帮助条目更新面向portlet项目的运行时资源中所述更新portlet类的代码。 / p>
根据RAD7信息中心的说法，您需要删除列出的大多数JSF portlet jar和use the ones that ship with RAD7。我可能错了，但我相信jsf-portletbridge.jar也可以在门户网站安装的某个地方使用。
您是否可以使用RAD7或更高版本？
