Java OSGi can'；我找不到激活剂

舱单：

Manifest-Version: 1.0
Bundle-Name: Mahjong
Bundle-Activator: MahjongActivator
Bundle-SymbolicName: Mahjong
Bundle-Version: 1.0.0
Import-Package: org.osgi.framework

编译和抖动：

$ javac -classpath equinox.jar src/start/*java
$ jar -cfm Mahjong.jar MahjongManifest.mf src/start/*class

激活剂：

package start;

import org.osgi.framework.*;

public class MahjongActivator implements BundleActivator
{
    public void start(BundleContext context)
    {
        System.out.println("Hi!");
    }
    public void stop(BundleContext context)
    {
        System.out.println("Bye!");
    }
}

然后我在OSGi中加载.jar，当我尝试

start（）

it时，它会说：

org.osgi.framework.BundleException: The activator MahjongActivator for bundle Mahjong is invalid

为什么？

应该是“Bundle Activator:start.MahjongActivator”--您省略了包名
