Question

我正在尝试在Jboss EAP6下查找EJB 3。我有一个名为 service-All 的maven EJB项目，其中我有两个包（接口和 Impl ），我还有一个其他java项目女巫命名为 ClientEJB 。这是一个界面及其实现的示例：

@Remote
public IClient{
void showClient(String name);
}

实施：

@Statless
@Remote(IClient.Class)
public ClientImpl(){
public void showClient(String name){
System.out.println("I'am Mr or Mme"+name);
}

关于java prject，这是主要类：

public MyClass{

  private IClient client;

  public static void main(String args[]){
    InvockClient().showClient("ClientTest");
  }

  public static IClient InvockClient(){
    final Hashtable jndiProperties = new Hashtable();
      jndiProperties.put(Context.URL_PKG_PREFIXES, "org.jboss.ejb.client.naming");
      jndiProperties.put("jboss.naming.client.ejb.context", true);
      Context context;
      IClient client= null;
      try {
          context = new InitialContext(jndiProperties);
      client=(IUpdateCleRepartition) context.lookup("ejb:service-All/service-All /"+Client.class.getSimpleName()+"!" + IClient.class.getName());
          context.close();
      } catch (NamingException e) {
          System.out.println(e.getMessage());
      }
      return client;
  }
}

这是jboss-ejb-client.properties我在src \ main \ resources中有它的女人

service-All.jar部署在jboss EAP6上，当我运行main方法时，它给了我这个：

log4j:WARN No appenders could be found for logger (org.jboss.logging).
log4j:WARN Please initialize the log4j system properly.

任何解决问题的想法！

Answer 1

我相信你的正确的jndi字符串应该是

ejb:/service-All/"+Client.class.getSimpleName()+"!" + IClient.class.getName()

＆＃34; service-All＆＃34;你没有属于，因为你没有将你的ejb包装在耳边。

另外，请勿忘记在您的媒体资源中传递用户名和密码

jndiProps.put(Context.SECURITY_PRINCIPAL, "peter");
jndiProps.put(Context.SECURITY_CREDENTIALS, "lois");

请记住，您必须将用户（＆＃34; peter＆＃34;在此示例中）添加到您的jboss中。在jboss-eap-6.0 / bin / add-user.sh（或windows的add-user.bat）中有一个脚本

您可以在此找到远程查找的文档

Answer 2

我的分数不允许我添加评论所以我正在写答案。除了@mendieta建议你可以检查你的ejb（ejb：service-All / service-All）是否在boot.log中正确部署

如果要进行远程查找，则必须在jndi属性中传递Context.PROVIDER_URL。您可以阅读有关here

的更多信息

Answer 3

这是正确的方法：

ejb:/service-All/"+Client.class.getSimpleName()+"!" + IClient.class.getName()

无法在JBoss EAP6下通过JNDI查找EJB远程
