I've run the tests directly to the service(without tomcat as stated in the
installation manual ) and it seems that there is a
java.lang.nullPointerException at
org.perfsonar.service.lookupService.xmlType.LSAction.getKeyFromMetadata. 
So does this mean that the service does not recognise the key(accessPoint)
in the request?  

To add some infrormation this is the output of the sonar.log file after I
submit a Register request
INFO: RequestHandler: Service received a request
----------------------
DEBUG: RequestHandler: Calling on parser to parse the request
----------------------
DEBUG: RequestHandler: Message object constructed from request. Request is
of type: LSRegisterRequest
----------------------

----------------------
DEBUG: LSRegisterRequest: MessageHandler created
----------------------
DEBUG: XmlTypeLSServiceEngine: started... 
----------------------
DEBUG: RequestHandler: Calling on MessageHandler [class
org.perfsonar.commons.messages.LSRegisterRequest] to satisfy request
----------------------
DEBUG: XmlTypeLSServiceEngine: takeAction for action [LS_REGISTER]
----------------------

DEBUG: ExistDbXmlrpcXmlStorageManager: initStorage with data repository
----------------------
DEBUG: LSRegisterAction: service.ls.lookup_info_timeout=true

----------------------


So it seems the service receives the request , the request is recognised as
LSRegister and the Messagehandler is created so does the LSService engine.
Then something goes terribly wrong.
There is nothing about this in the other logs. I hope this will help to
determine the problem

Hi Maciej,

It appears that the service fails only with the LSRegister request. For the
other types of request even for LSUpdate it works just fine. Were any
changes involving the handler of the Register request or maybe some schema
changes?

By the way, the server log could be useful to diagnose what happened 
with the server.

If you set up the server I can test some requests with my client.
Let me know if so. My yahoo_id and skype_id are "maciej_psnc".
