用于生成Service所需的各种ID

找了老半天，终于找到了，资料的整理很重要

11  * Group ID, and Module Specification ID based on the standard peer group Module Class ID.

23     public static void main(String[] args) {
24         // Create an entirely new Module Class ID.
25         ModuleClassID classID = IDFactory.newModuleClassID();
26         
27         // Create a Module Specification ID based on the generated Module Class ID.
28         ModuleSpecID specID = IDFactory.newModuleSpecID(classID);
29         
30         // Create an entirely new Peer Group ID.
31         PeerGroupID groupID = IDFactory.newPeerGroupID();
32         
33         // Create a Module Specification ID based on the peer group Module Class ID.
34         ModuleSpecID groupSpecID = IDFactory.newModuleSpecID(PeerGroup.allPurposePeerGroupSpecID.getBaseClass());
35         
36         // Print out the generated IDs.
37         System.out.println("Module Class ID: " + classID.toURI());
38         System.out.println("Module Spec ID: " + specID.toURI());
39         System.out.println("Peer Group ID: " + groupID.toURI());
40         System.out.println("Peer Group Module Spec ID: " + groupSpecID.toURI());
41     }

43 }

 附带一个以前写的jxta自定义服务的例子

JxtaServiceExample 

 说明：

jxtaserviceexample.SimpleServiceTest
测试类，执行该类可以看到，新建的group提供了SimpleService服务，并且通过该group获得该服务，并执行服务提供的alert方法。
jxtaserviceexample.impl.protocol.SimpleServiceImpl
服务的实现类
jxtaserviceexample.protocol.SimpleService
服务接口，仅增加了alert方法，供测试用
jxtaserviceexample.util.GeneratorID
