EJB @Local注释和@Remote注释不能一起使用 ：Remote和Local方式写在同一个类上，在部署到jboss4.0可以，jboss5.0报错
在4.X版本上就可以同时写在一个类上，代码如下：
public interface UserManager {
public void save(UserTest user);
}
@Stateless
@Remote
@Local
public class UserManagerBean implements UserManager, UserManagerLocal{
public void save(UserTest user) {
System.out.println("User[username=" + user.getUsername() +"]已保存" );
user.setId(1);
}
}
5.0版本就不行，报错如下：
Caused by: java.io.InvalidClassException: org.jboss.ejb3.remoting.IsLocalInterceptor; local class incompatible:stream classdesc serialVersionUID = -3758782076801249473, local classserialVersionUID = 337700910587744646

jboss4.x版本可以一个接口定义为remote和local两种方式，jboss5.0版本的则需要定义两个接口，并明确写明（当然具体实现的方式有多种）：代码如下：
public interface UserManager {
public void save(UserTest user);
}
public interface UserManagerLocal {
public void save(UserTest user);
}
@Stateless
@Remote({UserManager.class})
@Local({UserManagerLocal.class})
public class UserManagerBean implements UserManager, UserManagerLocal{
public void save(UserTest user) {
System.out.println("User[username=" + user.getUsername() +"]已保存" );
user.setId(1);
}
}
