javax.ejb.NoSuchEJBException：带有JBoss 7.1和Eclipse的EJBCLIENT000079

我对JavaEE还是很陌生，并试图运行一个小Hello World示例（https://ibytecode.com/blog/how-to-create-a-simple-ejb3-project-in-eclipse-jboss-7-1/），但是我对

感到困惑 
Exception in thread "main" javax.ejb.NoSuchEJBException: EJBCLIENT000079: Unable to discover destination for request for EJB StatelessEJBLocator for "/HelloWorldSessionBean/HelloWorldBean", view is interface com.ibytecode.business.HelloWorld, affinity is None

这可能只是一些初学者的错误，但我在这里迷路了。

这是我的源代码：

HelloWorld.java 

package com.ibytecode.business;
import javax.ejb.Remote;

@Remote
public interface HelloWorld {
    public String sayHello();
}

HelloWorldBean.java 

package com.ibytecode.businesslogic;
import com.ibytecode.business.HelloWorld;
import javax.ejb.Stateless;

/**
 * Session Bean implementation class HelloWorldBean
 */
@Stateless
public class HelloWorldBean implements HelloWorld {

    public HelloWorldBean() {
    }

    @Override
    public String sayHello() {
        return "Hello World !!!";
    }

}

我在Eclipse中创建了JBoss 7.1服务器，启动并部署了HelloWorldSessionBean。看来效果很好：

...
10:23:17,999 INFO  [org.jboss.as.ejb3.deployment] (MSC service thread 1-8) WFLYEJB0473: JNDI bindings for session bean named 'HelloWorldBean' in deployment unit 'deployment "HelloWorldSessionBean.jar"' are as follows:

    java:global/HelloWorldSessionBean/HelloWorldBean!com.ibytecode.business.HelloWorld
    java:app/HelloWorldSessionBean/HelloWorldBean!com.ibytecode.business.HelloWorld
    java:module/HelloWorldBean!com.ibytecode.business.HelloWorld
    java:jboss/exported/HelloWorldSessionBean/HelloWorldBean!com.ibytecode.business.HelloWorld
    java:global/HelloWorldSessionBean/HelloWorldBean
    java:app/HelloWorldSessionBean/HelloWorldBean
    java:module/HelloWorldBean
...

这是客户端代码：

package com.ibytecode.client;

import java.util.Properties;

import javax.naming.Context;
import javax.naming.InitialContext;
import javax.naming.NamingException;

import com.ibytecode.business.HelloWorld;

public class EJBApplicationClient {

    public static void main(String[] args) {
        InitialContext context = null;
        HelloWorld bean = null;
        try {
            Properties properties = new Properties();
            properties.put(Context.URL_PKG_PREFIXES, "org.jboss.ejb.client.naming");
            //properties.put(Context.INITIAL_CONTEXT_FACTORY, "org.jboss.naming.remote.client.InitialContextFactory");
            properties.put(Context.INITIAL_CONTEXT_FACTORY, "org.wildfly.naming.client.WildFlyInitialContextFactory");
            context = new InitialContext(properties);

            String lookupName = "ejb:/HelloWorldSessionBean/HelloWorldBean!com.ibytecode.business.HelloWorld";
            bean = (HelloWorld) context.lookup(lookupName);

        } catch (NamingException e) {
            e.printStackTrace();
        }
        System.out.println(bean.sayHello());
    }
}

然后我将jboss-ejb-client.properties放在类路径中：

endpoint.name=client-endpoint
remote.connectionprovider.create.options.org.xnio.Options.SSL_ENABLED=false

remote.connections=default

remote.connection.default.host=localhost
remote.connection.default.port = 4447
remote.connection.default.connect.options.org.xnio.Options.SASL_POLICY_NOANONYMOUS=false

remote.connection.default.username=admin
remote.connection.default.password=admin

当我将客户端作为纯Java应用程序运行时，得到以下输出：

我将jboss-client.jar中的$JBOSS-HOME/bin/client放在类路径中。

任何建议我做错了什么？ 非常感谢！

编辑：可能值得注意的是，由于bean.sayHello()导致发生了NoSuchEJBException。因此，也许这不是查找问题，而是连接问题？

1 个答案:

答案 0 :(得分：0)

您似乎对HelloWorldBean的lookupName（JNDI）错误。试试这个：

java:jboss/HelloWorldBean

此外，您还可以观看本文并在JBOSS管理页面上找到您的bean的正确JNDI名称。  How to find JNDI name in JBoss-7?
