perfsonar development work

Hi,

If the Flow MP is a JAVA service then you can use the generic LS 
Registration Component. I think we don't have this information on the 
wiki yet, so I'm forwarding the last email sent about how to properly 
configure your service to register with this component. If you want to 
send extra information (e.g. MA's send their configuration files as 
data), just set the service.ls.registration_file variable to point to 
the the xml that contains this information. It should be important to 
notice that the xml files used by the MA's for LS Registration are 
optional for this task.

Hi,

I just commited the changes to make LS registration without a xml file viable. In this case, the following should be configured:

In component.properties:

scheduler=org.perfsonar.commons.auxiliary.components.simplescheduler.Scheduler
registrator=org.perfsonar.service.commons.registration.LSRegistrationComponent

In service.properties:

component.registrator.interval=<Registration interval (this shouldn't be set too low, I use 300000>
component.registrator.scheduler_component=scheduler
service.r.ls_url=<LS URL> (e.g. http://200.128.80.172:8080/axis/services/LookupService)
service.r.access_point=<Service URL> (e.g. http\://200.237.192.9\:8080/axis/services/CLMPService )
service.r.service_name=<Service Name> (e.g. CLMP)
service.r.service_description=<Service Description> (e.g. CLMP Test)
service.r.service_type=<Service Type> (e.g. CLMP)
service.ls.registration_file=

The last parameter is necessary, even if blank. If it has no value then it will only use the service.r parameters above, if it has the path to a registration file (the xml file you were saying) then it will use that file for registration.

I think that's all that is needed, any problems ask.

Hi All,

I have a question for the Lookup Service developers, but could be of interest to all of you. As things stand in the SSH/Telnet MP, the complete configuration of the service sits in the service.properties file. Currently, while tying to register the service with the LS, I used the code from the Wiki, we are having some problems.

try {
ServiceLSRegistrator registrator = new GenericServiceLSRegistrator
(new PropertiesServiceDescription(),
new InformationXMLFileServiceContent("?????"));
registrator.initRegistrator();
Message responseMessage = registrator.register("http://selena.acad.bg:8070/axis/services/LookupService";);
} catch (PerfSONARException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}

The problem is that we don't have an XML file, and actually I don't quite get what is supposed to be described in that file.

Could someone shed some light on this?

Cheers,

Stijn

Hi Stijn,

Recently we had discussion with Guilherme () who made some changes to the LS registration that it could accept registration without configuration file.

I am not sure if he commited his changes (I think he did not), but you could contact Guilherme directly and ask him if he is going to commit the changes.
