开发环境：
MyEclipse5.5
JBoss4.0.4
JDK1.5.0.0.9
EJB3代码如下:
import javax.ejb.Remote;
@Remote
public interface HelloWorld {
public void sayHello();
}
------------------------------
import javax.ejb.Remote;
import javax.ejb.Stateless;
@Stateless
@Remote(HelloWorld.class)
public class HelloWorldBean implements HelloWorld {
public void sayHello(){
System.out.println( "Hello World! ");
}
}
测试代码:
public class TestSessionBean {
public static void main(String[] args) {
Properties props = new Properties();
props.setProperty( "java.naming.factory.initial ", "org.jnp.interfaces.NamingContextFactory ");
props.setProperty( "java.naming.provider.url ", "localhost:1099 ");
props.setProperty( "java.naming.factory.url.pkgs ", "org.jboss.naming:org.jnp.interfaces ");
InitialContext ctx;
try {
ctx = new InitialContext(props);
HelloWorld helloworld = (HelloWorld) ctx.lookup( "HelloWorldBean/remote ");
helloworld.sayHello();
} catch (NamingException e) {
e.printStackTrace();
}
}
}
错误信息:

在JBoss的控制台上看不到部署以后的信息
------解决方法--------------------------------------------------------
难道是大小写的原因？
------解决方法--------------------------------------------------------
没有找到 HelloWorldBean ，看看你的配置文件 我没用过ejb3.0。
但是ejb2.0里面 应该有ejb-jar.xml jboss.xml
看看jboss.xml 里面的 jndi-name 是不是 HelloWorldBean/remote
然后看看 ejb-jar.xml 里面 ejb-name 名字对应么
