Question

美好的一天。

我在Linux Centos上有一个VPS包含Tomcat 7.0.0和JDK 1.6.0.21-b06。我已经安装了我的JSF 2.2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，会发生上述错误：

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

javax.faces.el.MethodNotFoundException: javax.el.MethodNotFoundException: /homepage.xhtml @181,72 action="#{areapubblicaBean.GotoAiuto('homepage')}": Method not found: areariserv.AreapubblicaBean@161ebfb.GotoAiuto()
    javax.faces.component.MethodBindingMethodExpressionAdapter.invoke(MethodBindingMethodExpressionAdapter.java:91)
    com.sun.faces.application.ActionListenerImpl.processAction(ActionListenerImpl.java:102)
    javax.faces.component.UICommand.broadcast(UICommand.java:315)
    javax.faces.component.UIViewRoot.broadcastEvents(UIViewRoot.java:790)
    javax.faces.component.UIViewRoot.processApplication(UIViewRoot.java:1282)
    com.sun.faces.lifecycle.InvokeApplicationPhase.execute(InvokeApplicationPhase.java:81)
    com.sun.faces.lifecycle.Phase.doPhase(Phase.java:101)
    com.sun.faces.lifecycle.LifecycleImpl.execute(LifecycleImpl.java:198)
    javax.faces.webapp.FacesServlet.service(FacesServlet.java:646)

根本原因

javax.el.MethodNotFoundException: /homepage.xhtml @181,72 action="#{areapubblicaBean.GotoAiuto('homepage')}": Method not found: areariserv.AreapubblicaBean@161ebfb.GotoAiuto()
    com.sun.faces.facelets.el.TagMethodExpression.invoke(TagMethodExpression.java:109)

    com.sun.faces.lifecycle.LifecycleImpl.execute(LifecycleImpl.java:198)
    javax.faces.webapp.FacesServlet.service(FacesServlet.java:646)

当我使用Tomcat 7.0.54和JDK 1.7.0_25在我的PC环境中开发应用程序时，都运行正常。

为什么会这样？

祝福和好工作。

Answer 1

将您的方法名称从GotoAiuto更改为doAction（passedString）

public void doAction(String param){
System.out.println(param);
}

并测试。

Answer 2

我尝试过同样的结果。当我点击buttom时出现错误。

它可能依赖于Java版本（vps中为6，我的电脑中为7）？

最好的问候。
