【问题描述】：

当我在 Jetty 服务器上运行我的 JSF 应用程序时，它运行良好。

但是当我把它移到 Weblogic 服务器时，它开始给我这个错误。

wsListing.xhtml 如下：

                                <f:setPropertyActionListener
                                    target="#{wsListingBean.webServiceId}" value="filterabc" />
                            </h:commandLink></td>
                    </tr>
                    <tr>
                        <td>Third Web Service</td>
                    </tr>
                    <tr>
                        <td>Fourth Web Service</td>
                    </tr>
                    <tr>
                        <td>Fifth Web Service</td>
                    </tr>
                </table>
            </h:form>
        </div>
        <ui:include src="footer.xhtml" />
    </h:body>
</f:view>
</html>

当我点击任何命令链接时，就会出现这个问题：

<h:commandLink value="First Web Service"
                                    action="#{wsListingBean.action}">
                                    <f:setPropertyActionListener
                                        target="#{wsListingBean.webServiceId}" value="abcService" />

有人知道这个视图状态是什么吗？

SAM——这有什么好运气吗？如果是这样，请使用分辨率更新此内容，以便其他人可以从答案中受益。谢谢。

【解决方案1】：

您是否将 web.xml 中的 PROJECT_STAGE 设置为 Development？如果是这样，您能否将其切换到生产环境并查看问题是否消失？我在 WebLogic 上收到了类似的错误消息（如果不一样的话），并相信该更改已修复它。

【解决方案2】：

我在 web.xml 中加入了以下几行来修复错误

    <context-param>
    <!--description>
        The location where state information is saved. Valid values
        are 'server' (typically saved in HttpSession) and 'client'
        (typically saved as a hidden field in the form. Default is
        server.
        </description-->
    <param-name>javax.faces.STATE_SAVING_METHOD</param-name>
    <param-value>server</param-value>
</context-param>
<context-param>
    <!--description>
        Number of Views to be stored in the session when Server-Side
        State Saving is being used. Default is 20.
        </description-->
    <param-name>
        org.apache.myfaces.NUMBER_OF_VIEWS_IN_SESSION
    </param-name>
    <param-value>20</param-value>
</context-param>
