Question

我在尝试注入一个完全独立于我的JVM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JAXWS带注释的接口。

@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; 
.... 
}

稍后，我在尝试使用注入的服务时获得了NPE：

Caused by: java.lang.NullPointerException

我感觉我不理解WebServiceRef ...它仅用于JNDI传输吗？

您必须使用TomEE +，而不是TomEE（webprofile）。

见这里：http://openejb.979440.n4.nabble.com/JEE-Dependency-Injection-failure-on-WebServiceRef-results-in-bizzare-NullPointerException-td4656360.html#a4656377

使用@WebServiceRef进行依赖注入我做错了。但是怎么样？
