Introduction
The Node Access Library (NAL) is a Java Library that provides different functionalities to access the local node information. It allows to obtain the DHN unique ID, the Running Instance unique ID, the list of service running in the node, the running instance profile of the caller, and the node free disk space. Moreover, the NAL, gives access to the VO Maps and allows services to set/get both the Specific Data section and the State section in their Running Instance profile.
Implentation Overview
Each WSRF service should instantiate a NAL object in order to have access to node information (see Usage Example for details).
