Package org.eurogrid.broker.server.gt3 Description

Brokering engine updates for GT3-based IndexServices. Uses an ontology-driven translation engine.

To use the Globus Toolkit 3-based broker, you will need to configure the local resource checking module using a local section, like this:

  <local class="org.eurogrid.broker.server.gt3.GT3LocalResourceChecker"

    <!-- Where does the search proceed from? -->
    <grip:searchSpace sde="Host"

    <!-- XPath requires nasty stuff to work with namespaces -->
    <grip:namespace ns="glue"

    <!-- Where to read the translation ontology definition from -->
    <grip:map ref="file:/home/unicore/grip/U2GModel.xml"

    <!-- The fallback policy -->
    <grip:fallback> <!-- Note that the fallback class is fixed -->
