我从 eclipse 的外部 tomcat 6 运行我的JSF 2应用程序 一切都很好 但是当我尝试使用 maven tomcat插件

mvn tomcat:run

我在其中一个页面上遇到以下异常:

任何想法为什么?

2 个答案:

答案 0 :(得分:8)

  

java.lang.NoSuchMethodError:javax.el.E​​LResolver.invoke(Ljavax / el / ELContext; Ljava / lang / Object; Ljava / lang / Object; [Ljava / lang / Class; [Ljava / lang / Object;) Ljava /郎/对象;

该方法是在EL 2.2中引入的。此异常表明您的webapp /WEB-INF/lib受到旧版EL库的污染。 Tomcat 7.0本身已经附带了EL 2.2,但/WEB-INF/lib中的任何特定于容器的库都将在类加载中获得优先权。也许您已在pom.xml中声明了未提供的EL 2.1依赖项,而不是提供的EL 2.2依赖项。

答案 1 :(得分:1)

如果您一起使用Tomcat6和Maven,请从bin文件夹中删除el-api.jar,因为maven已将其添加到您的项目中。在pom.xml中,请务必添加与el-api库相关的版本标记。我尝试了这个解决方案,现在正在运行!

        <groupId>javax.el</groupId>
        <artifactId>el-api</artifactId>
        <version>2.2</version>
