EJBCLIENT000025：没有EJB接收器可用于处理？ [英] EJBCLIENT000025: No EJB receiver available for handling?

问题描述

但是我收到以下错误消息/例外：

  java.lang.IllegalStateException：EJBCLIENT000025：没有EJB接收器可用于处理[appName：xx-xx，moduleName： xx-xx-business-impl，distinctName：]组合用于调用上下文org.jboss.ejb.client.EJBClientInvocationContext@14bc02d

测试远程Bean TestService 及其实现是在一个EAR。

服务器类：

  @Remote 
 public interface TestService {
 
 public int getX（）; 
 
} 
 
 @Stateless 
 @Remote（TestService.class）
 public class TestServiceBean实现TestService {
 
 @Override 
 public int getX（）{
 // TODO自动生成的方法stub 
 return 1111; 
} 
} 
  

客户端代码：

  final Hashtable jndiProperties = new Hashtable（）; 
 jndiProperties.put（Context.URL_PKG_PREFIXES，org.jboss.ejb.client.naming）; 
 jndiProperties.put（Context.INITIAL_CONTEXT_FACTORY，org.jboss.naming.remote.client.InitialContextFactory）; 
 jndiProperties.put（Context.PROVIDER_URL，remote：// localhost：4447）; 
 
 String jndiName =ejb：orbis-dicom / orbis-dicom-business-impl // TestServiceBean！ 
 + TestService.class.getName（）; 
 logger.info（jndiName）; 
 
 final Context context = new InitialContext（jndiProperties）; 
 TestService service =（TestService）context.lookup（jndiName）; 
 
 logger.info（service.getX（））; 
  

jboss-ejb-client.properties：

解决方案

只要你想要，你需要保留引用的InitialContext（不能被垃圾回收） 查找远程EJB上的访问方法。

I am trying to connect to a remote EJB on my local JBoss 7.2 from an executable Java application (local not on JBoss).

But I get the following error/Exception :

java.lang.IllegalStateException: EJBCLIENT000025: No EJB receiver available for handling [appName:xx-xx, moduleName:xx-xx-business-impl, distinctName:] combination for invocation context org.jboss.ejb.client.EJBClientInvocationContext@14bc02d

    at com.sun.proxy.$Proxy0.getX(Unknown Source)
    at com...ris.client.PACSServiceTest.main(PACSServiceTest.java:71)

The test remote bean TestService and its implementation is in an EAR.

Server Classes:

@Remote
public interface TestService {

    public int getX();

}

@Stateless
@Remote(TestService.class)
public class TestServiceBean implements TestService{

    @Override
    public int getX() {
        // TODO Auto-generated method stub
        return 1111;
    }
}

Client code:

final Hashtable jndiProperties = new Hashtable();
jndiProperties.put(Context.URL_PKG_PREFIXES, "org.jboss.ejb.client.naming");
jndiProperties.put(Context.INITIAL_CONTEXT_FACTORY, "org.jboss.naming.remote.client.InitialContextFactory");
jndiProperties.put(Context.PROVIDER_URL,"remote://localhost:4447");

String jndiName = "ejb:orbis-dicom/orbis-dicom-business-impl//TestServiceBean!"
                  + TestService.class.getName();
logger.info(jndiName);

final Context context = new InitialContext(jndiProperties);
TestService service = (TestService) context.lookup(jndiName);

logger.info(service.getX());

jboss-ejb-client.properties:

Any ideas? Thanks in advance!

解决方案

You need to keep the InitialContext referenced (it must not be garbage collected) as long as you want to access methods on the "lookup'ed" Remote EJB.
