我在尝试注入与我的 JVM 完全分离的 Web 服务时遇到异常。

我的环境是 TomEE v1.0.0,它是一个 JEE6 webprofile 容器。

ThemeQueryService 是一个带有 JAXWS 注释的接口。

@SessionScoped 
@Named("managedBeanMB") 
public class ManagedBeanMB implements Serializable { 
        private static final long serialVersionUID = 1L; 

        @WebServiceRef(
            wsdlLocation = "http://localhost:8777/services/queryService?wsdl") 
        private QueryService queryService; 
.... 
} 

后来,在尝试使用注入服务时,我得到了一个 NPE:

Caused by: java.lang.NullPointerException 
        at org.apache.openejb.core.ivm.naming.JaxWsServiceReference.getObject(JaxWsServiceReference.java:73)

        at org.apache.webbeans.component.AbstractOwbBean.create(AbstractOwbBean.java:182)

我觉得我不理解 WebServiceRef... 它仅用于 JNDI 传输吗?

您必须使用 TomEE+,而不是 TomEE(webprofile)。
