Ejb的远程调用问题
我刚学EJB3，写了个helloworld就出现问题了。帮忙看一下吧。服务器用JBOSS
《服务器端》
package com.xxx.xxx.ejb;
public interface FirstEjb {
public String SaySomething(String name);
}
package com.xxx.xxx.ejb;
import javax.ejb.Remote;
import javax.ejb.Stateless;
@Stateless
@Remote
public class FirstEjbBean implements FirstEjb {
public String SaySomething(String name) {
return "FirstEjb " + name;
}
}
《客户端》
package com.xxx.xxx.ejb;
import javax.naming.InitialContext;
import javax.naming.NamingException;
public class EjbClient {
/**
* @param args
*/
public static void main(String[] args) {
try {
InitialContext context = new InitialContext();
FirstEjb firstEjb = (FirstEjb)context.lookup("FirstEjbBean/remote");
System.out.println(firstEjb.SaySomething("zhangsan"));
} catch (NamingException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
}
【JNDI.properties】
# DO NOT EDIT THIS FILE UNLESS YOU KNOW WHAT YOU ARE DOING
#
java.naming.factory.initial=org.jnp.interfaces.NamingContextFactory
java.naming.factory.url.pkgs=org.jboss.naming:org.jnp.interfaces
java.naming.provider.url=localhost

另外，怎么能在Ejb导入到JBOSS时，控制台显示导入的EJBBEAn的名字。谢谢了
[解决办法]
FirstEjbBean加上下面的注释：
@Remote(FirstEjb.class)
@RemoteBinding(jndiBinding = "FirstEjbBean/remote")
然后重新部署到jboss目录，重新启动jboss；
你现在错误的原因：1、ejb未部署成功;2、没有找到FirstEjbBean的名字
------解决方案--------------------
把bean打成jar包放到jboss -> default目录下了吗
