Я новичок в OSGi и создаю первую реализацию DS.
Все закодировано по "книге", но при запуске я получаю эту ошибку:

Это файл configuration.xml модуля, который я хочу использовать в других:
<scr:component xmlns:scr="http://www.osgi.org/xmlns/scr/v1.1.0" activate="startup" deactivate="shutdown" immediate="true" name="com.mine.logger.storeindb">
<implementation class="com.mine.logger.internal.storeindb.StoreLog"/>
<service>
<provide interface="com.mine.logger.storeindb.IStoreLog"/>
</service>
</scr:component>
А это файл configuration.xml модуля, который будет его использовать:
<scr:component xmlns:scr="http://www.osgi.org/xmlns/scr/v1.1.0" name="com.mine.logger.udp">
<implementation class="com.mine.logger.internal.udp.UdpListener"/>
<reference bind="setStoreLog" interface="com.mine.logger.storeindb.IStoreLog" name="storelog" unbind="unsetStoreLog"/>
</scr:component>
Код для привязки и отвязки:
private IStoreLog storeLog;
public void setStoreLog(IStoreLog value)
{
System.err.println("UdpListener > setStoreLog");
this.storeLog = value;
}
public void unsetStoreLog(IStoreLog value)
{
System.err.println("UdpListener > unsetStoreLog");
if (this.storeLog == value) {
this.storeLog = null;
}
}
Есть идеи? Спасибо, Фрэнк
