下午好，如果你能帮助我，我在设置jsf，primefaces和jpa（java.lang.NoClassDefFoundError：javax / persistence / Persistence）时遇到错误！遵循以下错误：

这意味着你的类路径中找不到javax.persistence.Persistence类，我猜你没有使用应用服务器，我认为你正在使用tomcat，所以你必须将你的应用程序所需的所有库放在您的服务器的lib，或者您可以将所有jar复制到appplication的WEB-INF / lib文件夹，因此您必须将jpa库hibernate-entitymanager-xxxx.jar和其他文件复制到WEB-INF / lib文件夹< / p>

同一个朋友，它有效！我将pom.xml中的所有依赖项放在tomcat中，然后就可以了！谢谢！
