register

void register(ServiceURL url,
              Dictionary attributes)
              throws ServiceLocationException

Register a service with the SLP framework. The service will be registered with all known DAs that support the default scope and with the local SA registry for multicast discovery.

Parameters:

url - the ServiceURL of the service.

attributes - a Dictionary of attributes for the service. RFC 2614 proposes a Vector of attribute-value-pairs here but the Dictionary makes this implementation more close to OSGi.

Throws:

ServiceLocationException - in case that the registration failed for any reason.

register

void register(ServiceURL url,
              List scopes,
              Dictionary attributes)
              throws ServiceLocationException

Register a service with the SLP framework. The service will be registered with all known DAs that support at least one of the given scopes and with the local SA registry for multicast discovery.

Parameters:

url - the ServiceURL of the service.

scopes - a List of scope names as Strings.

attributes - a Dictionary of attributes for the service. RFC 2614 proposes a Vector of attribute-value-pairs here but the Dictionary makes this implementation more close to OSGi

Throws:

ServiceLocationException - in case that the registration failed for any reason.

deregister

void deregister(ServiceURL url)
                throws ServiceLocationException

Unregister a service with the SLP framework. The service will be unregistered with all known DAs in the scopes that it was registered in.

Parameters:

url - the ServiceURL of the service.

Throws:

ServiceLocationException - in case that the deregistration failed for any reason.

deregister

void deregister(ServiceURL url,
                List scopes)
                throws ServiceLocationException
