Tomcat 我无法在JSF2.2上传递方法的参数

你好

在Linux Centos上，我有一个包含Tomcat 7.0.0和JDK 1.6.0.21-b06的VPS。 我已经安装了JSF2.2应用程序（Mojarra 2.2.7和Primefaces 5.0）。 当我调用具有参数的ManagedBean方法时，会出现上述错误：

javax.servlet.ServletException: javax.el.MethodNotFoundException: /homepage.xhtml @181,72 action="#{areapubblicaBean.GotoAiuto('homepage')}": Method not found: areariserv.AreapubblicaBean@161ebfb.GotoAiuto()
    javax.faces.webapp.FacesServlet.service(FacesServlet.java:659)

根本原因

当我在我的PC环境中使用Tomcat 7.0.54和JDK 1.7.0_25开发应用程序时，它们都运行正常

为什么会发生这种情况

致以最良好的问候和良好的工作

Stefano Erani

将方法名称从GotoAiuto更改为doAction（passedString）

---

和测试。

我试过，结果也一样。 当我点击按钮时出现错误

它可能取决于Java版本（vps中6个，我的电脑中7个）

致以最良好的祝愿
