环境：
JBoss4.2GA
JBoss IED
写有下面简单的stateless session bean:
＝＝＝＝＝＝Remote 接口＝＝＝＝＝＝＝＝＝
public interface Hello {
public void hello();
}
＝＝＝＝＝＝＝Bean 类＝＝＝＝＝＝＝＝＝＝＝
import javax.ejb.Remote;
import javax.ejb.Stateless;
@Stateless
@Remote(Hello.class)
public class HelloBean implements Hello{
public void hello(){
System.out.println("hello()");
}
}
＝＝＝＝＝＝测试代码＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝
public class Client {
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");
InitialContext ctx;
try {
ctx = new InitialContext(props);
Hello hello = (Hello) ctx.lookup("HelloBean/remote");
hello.hello();
} catch (NamingException e) {
e.printStackTrace();
}
}
}
＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝
将jar包部署到JBoss下后，用Jsp页面测试，正常；但是，在Eclipse中运行上面的Client.java时出现异常，如下：
Exception in thread "main" java.lang.reflect.UndeclaredThrowableException

请问这是什么原因啊？
