Client如何访问Glassfish 提供的远程EJB

EJB所有返回值必须实现 Serializable接口，否则会报些莫名其妙的错误.
并把 Glassfish 的 appserv-rt.jar 和 javaee.jar 包 客户程序的类路径

@Stateless(mappedName="ejb/MainActionJNDI")//远程JNDI
@Name("MainAction")

@Interceptors({org.jboss.seam.ejb.SeamInterceptor.class})
@AutoCreate
public class MainActionBean implements MainAction,MainActionRemote {

import javax.naming.InitialContext;
