引起的：javax.naming.NameNotFoundException - Name [Class / object]在此上下文中未绑定 [英] Caused by: javax.naming.NameNotFoundException - Name [Class/object] is not bound in this Context

问题描述

我正在开发一个使用JSF / Tomcat 7 / Maven的动态Web项目/ Java 7

每当我在服务器上运行项目，我得到这个：

  javax.naming.NameNotFoundException：Name [.... ProjectManagement / service]在此上下文中未绑定。无法找到[de.hhn.team3.artzpraxismanagement.ProjectManagement]。

这里是我的Class ProjectManagement

 包... artzpraxismanagement; 
 
 @Named 
 @ManagedBean 
 @SessionScoped 
 public class ProjectManagement实现Serializable {
 private static final long serialVersionUID = 1L; 
 @EJB私人服务服务; 
  

和我的服务类

  @ManagedBean 
  

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

< blockquote>

我已经尝试过不同的解决方案，比如在WebContent / lib中删除Tomcat Jars，但没有帮助。

我猜我的 ProjectManagement 类不在context.xml中。

我该怎么做？ >

解决方案

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，则必须将应用程序部署在真正的Java EE应用程序服务器上，例如 JBoss 7 ， GlassFish 3 或 TomEE （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，但必须支付才能获取/使用它们）。如果您继续在Tomcat中部署，您将永远不会成功。

如果您仍然只想使用Tomcat，则可以将所有这些 @ EJB 和其他Java EE注释（例如CDI注释，如 @Named ）。

顺便说一句，请遵循一个关于JSF或CDI的精通教程。您不能同时以$ @Named 和 @ManagedBean 的形式装饰。

have a problem that am dealing with since 6 hours but don't get to solve it.

Am developping a Dynamic web project using JSF/Tomcat 7/ Maven/Java 7

Everytime I run the project on the server I get this:

here is my Class ProjectManagement

 package ...artzpraxismanagement;

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

and my Service Class

@ManagedBean

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

I have tried different solution like delete Tomcat Jars in WebContent/lib but it doesn't help.

I guess my ProjectManagement class is not bounded in the context.xml.

How can I do that please?

解决方案

EJBs and CDI don't work in Tomcat by default since Tomcat is just a Servlet Container. If you want to use them you must deploy your application on a real Java EE application server like JBoss 7, GlassFish 3 or TomEE (note that these are free, there are others like IBM WebSphere and Oracle WebLogic that are Java EE 6 application servers but you must pay in order to acquire/use them). If you keep deploying this in Tomcat, you will never succeed.

If you still want to use Tomcat only, then get rid of all those @EJB and other Java EE annotations (e.g. CDI annotations like @Named).

By the way, please follow a good sane tutorial on JSF or CDI. You can't have a bean decorated as @Named and @ManagedBean at the same time.
