1. Ching Yi, Chan (qrtt1) OSGi 入門與簡介

2. WHAT IS OSGi ? The OSGi™ specifications define a standardized, component-oriented, computing environment for networked services that is the foundation of an enhanced service-oriented architecture. Adding an OSGi Service Platform to a networked device (embedded as well as servers), adds the capability to manage the lifecycle of the software components in the device from anywhere in the network. Software components can be installed, updated, or removed on the fly without ever having to disrupt the operation of the device.

20. OSGi Service & URL Shorten Bundle

24. Service Filter (LDAP Filter) context. getAllServiceReferences ( IShortenURL.class.getName(), String. format ( "(name=%s)" , name) ); “ (name=0rz.tw)” “ (name=tinyurl)” 過濾含有屬性 name ，且值為 0rz.tw 的 Service 過濾含有屬性 name ，且值為 tinyurl 的 Service

25. Service Filter (LDAP Filter) 選擇具有 cn 屬性且值為 Babs Jensen 者 "(cn=Babs Jensen)" 以 ! 排除具有 cn 屬性且值為 Tim Howes 者 "(!(cn=Tim Howes))" 選擇具有 objectclass 屬性且值為 Persion 並且不含屬性 sn 值 Jensen 與屬性 cn 且值為 Babs J 開頭者 "(& (" + Constants.OBJECTCLASS + "=Person) (|(sn=Jensen)(cn=Babs J*)) )" "(o=univ*of*mich*)"

27. tracker = new ServiceTracker(context, IShortenURL.class.getName(), null) { public Object addingService (ServiceReference reference) { ui.resetAvailableServiceList(context); ui.updateStatus(String.format("Service [%s] is available.", reference.getProperty("name"))); return super.addingService(reference); } public void removedService (ServiceReference reference, Object service) { ui.resetAvailableServiceList(context); ui.updateStatus(String.format("Service [%s] is unavailable.", reference.getProperty("name"))); super.removedService(reference, service); } }; tracker. open ();
