我在嘗試注入與我的JVM完全分離的Web服務時收到異常。依賴注入@WebServiceRef我做錯了。但是如何？
我的環境是TomEE v1.0.0，它是一個JEE6 webprofile容器。
ThemeQueryService是一個JAXWS註釋接口。
@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;
....
}
後來，我在嘗試使用注射服務時的NPE：
Caused by: java.lang.NullPointerException

給我的感覺，我不明白WebServiceRef ......難道只能用於JNDI運輸？
