Question

我正在尝试使用primefaces4和大气2.0.1在Glassfish4中配置primepush。我的web.xml为：

Web.xml中：

POM.xml

        </dependency>
    </dependencies>

我尝试过论坛代码： primefaces forum 并改变气氛 - 运行时间。我错过了什么吗？

我有以下错误：

严重：加载应用时出现异常： java.lang.IllegalStateException：ContainerBase.addChild：start： org.apache.catalina.LifecycleException： org.apache.catalina.LifecycleException： java.lang.ClassNotFoundException：org.atmosphere.cpr.AtmosphereServlet

Answer 1

您已按照提供的方式定义了依赖关系。

<dependency>
    <groupId>org.atmosphere</groupId>
    <artifactId>atmosphere-runtime</artifactId>
    <version>2.0.1</version>
    <scope>provided</scope>
</dependency>

这意味着您只需要在编译期间使用依赖项，而其他东西在运行时提供jar。见Maven's Scope Documentation

您可能希望使用运行时，因为通常只在运行时需要大气运行时工件：

<scope>runtime</scope>

如果在编译期间需要编译，则编译：

<scope>compile</scope>

使用PF4，GF4和Atmosphere-2.0.1配置primepush
