Question

清单：

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＆amp;不和谐：

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

激活者：

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()时，它说：

org.osgi.framework.BundleException: The activator MahjongActivator for bundle Mahjong is invalid
        at org.eclipse.osgi.framework.internal.core.AbstractBundle.loadBundleActivator(AbstractBundle.java:156)

...
Caused by: java.lang.ClassNotFoundException: MahjongActivator

为什么？

Answer 1

它应该是“Bundle-Activator：start.MahjongActivator” - 你省略了包名。

OSGi找不到激活剂
