New Revision: 4053

Modified:
   
trunk/geant2_java-xml-ls/src/main/java/org/perfsonar/service/lookupService/xmlType/storage/exist/XQueryExistDAOImpl.java
Log:
LS registration will send now one XQuery with new data instead od multiple 
queries. It could speed up a bit 
the service and resolve some problems with the registration.
