Java 部分项目未在Tomcat 6上运行

我有一个Tomcat6服务器，我正在开发一个与JavaEE5兼容的RESTWeb服务

该项目是在NetBeans 6.9.1上开发的。我成功地部署了项目，程序运行了，我在浏览器中收到了一个网页。现在，该计划的一部分工作。也就是说，我可以从web站点访问javabean，检索数据并将其显示在web页面上

但是我无法访问web服务。web服务是使用Java企业bean（EJB）实现的。服务器上是否缺少EJB或REST web服务的库

这是我在页面上看到的错误： HTTP状态404。说明：请求的资源不可用。有什么问题吗

这是我在NetBeans上得到的结果：

提供所提供的数据不能说明您的服务器上是否缺少库。只有你能证实这一点

从堆栈跟踪来看，似乎至少jersey存在于某个地方（可能在.war的WEB-INF/lib中，或者如果.war也像Tomcat的lib目录一样在完整的JavaEE上运行）

既然您声明现有代码使用EJB，那么您还应该在某个地方有一个EJB实现。Tomcat不支持EJB，因为它只是一个

Servlet容器

。OpenEJB将是一个可能的实现。检查这样的实现是否存在
