51 | * This class provides access to the <code>RuleRuntime</code> and | |
52 | * <code>RuleAdministrator</code> implementation supplied by Drools | |
53 | * when running under J2SE. | |
54 | * <p/> | |
55 | * This class should be used in environments without a JNDI provider - | |
56 | * typically when writing standalone J2SE clients. Within the J2EE environment | |
57 | * the <code>RuleServiceProvider</code> implementation class provided by Drools | |
58 | * should be retrieved using a JNDI lookup. | |
