Question

간단한 WebSevice

@WebService 
@Stateless 
public class HistoryFormatterWebService implements IHistoryFormatterWebService 
{ 
    @EJB 
    private IHistoryFormatter historyFormatter; 

    public byte[] formatHistory(final byte[] data) 
    { 
     System.err.println("hello from service"); 

     return null; 
    } 
} 

IHistoryFormatter

@Local 
public interface IHistoryFormatter 
{ 
// .. 
} 

IHistoryFormatter는 다른 프로젝트 (쿼리 ear.ear)에서 콩하지만 그는 또한 JBoss에서 배포됩니다.
내 웹 서비스가 jBoss에 정상적으로 배포됩니다. 그리고 JBoss는 내가 할

11:17:09,506 INFO [JmxKernelAbstraction] installing MBean: jboss.j2ee:ear=wsformatter-ear-1.0-SNAPSHOT.ear,jar=wsformatter-ejb-1.0-SNAPSHOT.jar,name=HistoryFormatterWebService,service=EJB3 with dependencies:

11:17:09,568 INFO [EJBContainer] STARTED EJB: com.wsformatter.HistoryFormatterWebService ejbName: HistoryFormatterWebService 

을 썼다 그러나 나는 그것에 요청을 보낼 때 (SoapUI를 사용하여) 예외

누군가가 나를 도울 수 있습니까?

Answer 1

그냥 추측은 :

java.lang.RuntimeException: Non matching type for inject of field: 
[...] com.softcomputer.softlab.lquery.service.IHistoryFormatter [...] for type: 
[...] of [...] com.softcomputer.softlab.lquery.service.IHistoryFormatter[...] 

이 두 클래스 로더에 의해로드 이 클래스 IHistoryFormatter 있다는 것을 나에게 소리. 클래스가 같은 이름을 가지고 있더라도 다른 클래스 로더에 의해로드 된 클래스는 서로 다른 것으로 간주됩니다.

인터페이스 클래스의 패키징을 확인하십시오. 이상적으로는 JBoss에서 정확히 한 곳에서 사용할 수 있어야합니다.
