实际上我是Java-ee规范的新手，我正在开发一个用于培训目的的简单项目 主要思想是创建一个名为“firstEJB”的EJB项目，它包含一个简单的Java远程，无状态接口和一个简单的实现类。 第二个项目是一个java项目，以便通过context.lookup（）方法使用已部署在服务器上的EJB。 问题是查找方法总是抛出类型命名异常的异常，我很确定我正在使用正确的JNDI名称。
PS：
- 我正在使用mac Os x High Sierra作为操作系统
- Wildfly 9.0.2.Final作为应用程序服务器
- Java SE 1.8
- EJB版本3.2
- Javax 7.0
这是项目架构click me
接口
package com.esprit;
import javax.ejb.Remote;
@Remote
public interface Calculette {
float add(float a, float b);
}
实施
package com.esprit;
import javax.ejb.Stateless;
@Stateful
public class CalculetteImplementation implements Calculette {
@Override
public float add(float a, float b) {
// TODO Auto-generated method stub
return 0;
}
}
客户端应用程序主要方法
package com.calculette.test;
import javax.naming.Context;
import javax.naming.InitialContext;
import javax.naming.NamingException;
import com.esprit.Calculette;
public class CalculetteTest {
public static void main(String[] args){
Context con;
try {
con = new InitialContext();
Object o = con.lookup("/firstEJB/CalculetteImplementation!com.esprit.Calculette");
Calculette calculette = (Calculette) o;
} catch (NamingException e) {
// TODO Auto-generated catch block
e.printStackTrace();
e.getCause();
}
}
}

答案 0 :(得分：1)
您必须在客户端查找时使用完全限定名称。例如
Java的：全球/ firstEJB / CalculetteImplementation com.esprit.Calculette
请注意，您可以使用Code to list all the entries in jndi on remote machine中描述的解决方案来确保EJB bean已成功注册。
