It is according to three conceptual level designs defined in OSGI specifications：
Module layer：Focus on packing and share code.Module layer defines the concept of OSGI modules, and it is referred to as one
bundle.Bundle files are jar files comprising metadata (with regard to the data of data), by class file and related resource
Composition.It is the multiple logic modules for constituting an application-specific.
Service layer：Focus on the interaction and communication of inter-module in module, particularly module.Service layer supports and facilitates
One flexible application programming model.Relate generally to service-oriented issue, lookup and binding interactive mode, i.e. ISP
Service is published to service register center, then service client searches operational clothes by search service registration center
Business.
Life cycle layer：Module management and the access to bottom OSGI frameworks when focusing on providing execution.Life cycle layer
Define in OSGI frameworks is how dynamic is installed and manage.Life cycle layer defines the behaviour of bundle life cycle
Make (as installed, updating, start, stop and unload).The operation of these life cycle allows to a kind of well-defined side
Formula dynamically provides, manages and improve application program.
Bundle is the modular model in OSGI.Include class files and corresponding in the jar bags of standard Java platform
Resource file, bundle files can simply be not understood as the jar bags that increased metadata.Wrap in one bundle file
Java classes and some other data resources are contained, these data can be html file, help document and icon etc..Each
Bundle files all correspond to one uniquely and keep constant id number in life cycle, and the ID is by OSGI frameworks point
Match somebody with somebody.
For ease of description, by module definition it is：One logically encapsulates the set for realizing class, and one sub based on class is realized
The optional public API of collection, and a set to external code dependence.Can be bundle document understandings from client layer
For One function module.Bundle files can be imported and exported from project, and can be with other bundle in project altogether
Enjoy jar file.In the embodiment of the present invention by bundle document definitions can be：One modular physical location, with jar file
Form includes code, resource and metadata, the encapsulation border of logical modular when the border of wherein jar file also serves as executing.
Context when BundleContext refers to that module is run in OSGI frameworks, the context provide module with
The method that OSGI frameworks are interacted (as application provides the method for operating OSGI frameworks during execution).During starting module, OSGI
Framework can create a corresponding BundleContext object, but the object can not be transmitted between the modules, this be in order to
