I am sorry for the getting the numbers fumbled up.
I was talking about
public JoinManager(Object serviceProxy,
Entry[] attrSets,
ServiceIDListener callback,
DiscoveryManagement discoveryMgr,
LeaseRenewalManager leaseMgr)
throws IOException
For the config file I was talking about other constructors that contain last
argument as Configuration object.
I am again sorry for not being precise.
Now, as from the specs I think Entry[] attributes means the attributes that are
used to process, manage and identify a
service as there can be many services and these attributes help us to match a
minimum of one services.
I have created an Entry array using EmptyConfiguration from
net.jini.config.EmptyConfiguration as
Entry[] myattrs = (Entry[])
EmptyConfiguration.INSTANCE.getEntry("com.siolabs.jini.Server","sioLabs" ,
Entry[].class);
with the help from blog
http://www.jroller.com/dancres/entry/how_to_write_a_jini
If something above is wrong please correct me .
I have written following steps.
1. Writing a Service Interface
2. Writing a Service Implementation Class
2.1 Used BasicJeriExporter
2.2 Created Service Id
2.3 Created a proxy Object for Service
2.4 Finding reggie instances using LookupLocator
2.5 Getting a LookupDiscoveryManager
2.6 Got Entry[] using EmptyConfiguration
2.7 Create a JoinManagerInstance with the constructor I specified above
I think that my service is completed now or Is there something left??
