我最近将JSF应用程序(使用primefaces)从glassfish 3.1迁移到了tomcat7服务器。以前通过actionlistener 属性work将enum值作为字符串传递给托管bean方法(不需要使用转换器将字符串转换为enum),但现在失败了 javax.el.MethodNotFoundException。
actionlistener
javax.el.MethodNotFoundException
JSF页面:
<h:form> <h:outputLabel value="Title"/><br/> <p:inputText value="#{lobController.current.title}"/> <p:commandButton action="#{lobController.create('CAR')}" value=”Post”/>
<h:form> <h:outputLabel value="Title"/><br/> <p:inputText value="#{lobController.current.title}"/> <p:commandButton action="#{lobController.create('CAR')}"
value=”Post”/>
bean豆法
public void create(Type type) { ... }
日志消息:

如果我按以下方式更改托管bean方法,则此方法开始工作:
public void create(String type) { Type type = Type.valueOf(type); ... }
在Tomcat 7.0.14上将Primefaces 3.1与JSF 2.1.6结合使用
这是Tomcat EL实现中的错误。我已经为您报告了此问题:问题52970。希望他们不会像我以前的报告那样挑剔。
在他们解决问题之前,最好的选择是将Glassfish 3的EL 2.2实现JAR文件复制到您的/WEB-INF/libWeb应用程序中,并通过以下命令输入Mojarra来使用它web.xml:
/WEB-INF/lib
web.xml
<context-param> <param-name>com.sun.faces.expressionFactory</param-name> <param-value>com.sun.el.ExpressionFactoryImpl</param-value> </context-param>
更新 :票证提到它已修复,它将在7.0.27及更高版本中。
