}在网上搜索了一段时间后，我发现了以下提供线索的文章： 我还偶然发现： 似乎发生的事情是在EJB-Jar.xml中，我将EJB声明为无状态会话bean，并且通过不在java类中注释它们，CDI/Weld将它们默认为@Dependent，例如，在JBoss文章
中，没有明确定义作用域的CDIBean默认为@Dependent scope。 package net.mycompany.my.service;
import javax.ejb.Stateless;
import javax.ws.rs.ApplicationPath;
import javax.ws.rs.core.Application;
import java.util.HashSet;
import java.util.Set;
@Stateless
@ApplicationPath(value="/C1AuthService")
public class MyIPAuthJaxRsServiceApplication extends Application {
private Set singletons = new HashSet();
public MyIPAuthJaxRsServiceApplication() {
singletons.add(new MyIPAuthJaxRsService());
}
}@Statelessimport javax.ejb.Stateless
编辑-正如@SteveC所指出的，我已经删除了覆盖，但当我试图按照他的建议从MyIPAuthJaxRsServiceApplication中删除@Stateless时，我再次得到了MyIPAuthJaxRsServiceApplication的异常。同样值得注意的是，这个例子甚至不起作用，因此在EJB-Jar.xml中有EJB，甚至不需要注释，我试图在EAR中使用一个EJB项目和Jar，用JAX-RS注释EJB，但显然它不受支持，因为我在这里与JBoss的同事一起工作
看起来您必须为JAX-RS提供一个servlet容器，而EJB可以提供web服务注释这一事实并不意味着它们使用的是servlet容器——哦，我试过了！。也，这个问答更多的是为了修复没有明确定义作用域的CDIBean，默认情况下它是@Dependent scope。myipauthjaxrssserviceapplication@Stateless@Dependent is allowed
