有一个问题,从6个小时开始处理,但没有解决它。

使用JSF / Tomcat 7 / Maven / Java 7开发动态Web项目

每次我在服务器上运行项目时都会得到这个:

这是我的课程项目管理

 package ...artzpraxismanagement;

 @Named 
@ManagedBean 
@SessionScoped 
public class ProjectManagement implements Serializable {        
private static final long serialVersionUID = 1L;     
 @EJB   private Services service;

和我的服务类

@ManagedBean
@SessionScoped
@Local
public class Services implements Serializable {...}

我尝试过不同的解决方案,例如在WebContent / lib中删除Tomcat Jars,但它没有帮助。

我想我的ProjectManagement类不在context.xml中。

我该怎么办呢?

默认情况下,EJB和CDI在Tomcat中不起作用,因为Tomcat只是一个Servlet容器。如果要使用它们,则必须在真实的​​Java EE应用程序服务器上部署应用程序,如JBoss 7GlassFish 3TomEE(请注意,这些是免费的,还有其他类似IBM WebSphere和Oracle WebLogic是Java EE 6应用程序服务器,但您必须付费才能获取/使用它们。如果你继续在Tomcat中部署它,你就永远不会成功。

如果您仍然只想使用Tomcat,那么请删除所有@EJB和其他Java EE注释(例如@Named等CDI注释。

顺便说一句,请遵循JSF或CDI上的理智教程。你不能同时将@Named@ManagedBean装饰成豆。
