搞了有一会了，搞不出来。

在Web应用程序中我写的

StudentService.java

interface StudentService extends Remote{
    List getStudents()
}

StudentServiceImpl .java

class StudentServiceImpl implements StudentService{
static expose = ['hessian', 'rmi']
static remote = [
  protocol: 'hessian',
  iface: StudentService,
  host: 'localhost',
  port: '8080',
  webcontext: 'Student',
]
@Override
public List getStudents() {
  ArrayList students=Student.list()
  println students
  return students;
}
}

Student这个类我序列化了。  我已经安装了插件remoting，其实我是按照http://www.grails.org/plugin/remoting 一步一步操作的。

在客户端的应用程序写的代码：并且加入了hessian-3.2.0.jar

StudentService.java

interface StudentService{
List getStudents()
}

RemoteClient .java

public class RemoteClient {
public static main(args) {
  def url = "http://localhost:8080/GrailsTest/hessian/StudentServiceImpl"
  def factory = new HessianProxyFactory()
  def basic = factory.create(StudentService.class,url)
  println basic.getStudents()
}

}

在web控制台的错误：

org.springframework.beans.factory.NoSuchBeanDefinitionException: No bean named 'hessian.StudentServiceImpl' is defined

在客户端应用程序的错误：

Exception in thread "main" com.caucho.hessian.client.HessianConnectionException: 500: java.io.IOException: Server returned HTTP response code: 500 for URL: http://localhost:8080/GrailsTest/hessian/StudentServiceImpl



我的分析：我知道web这里没有配置好，唉，菜鸟嘛，能力有限。。求帮助了。谢谢哈
