 /**
- * Service locator pattern, used to lookup JNDI-services
+ * 
+ * The Service Locator pattern is a design pattern used in software development 
+ * to encapsulate the processes involved in obtaining a service with a strong 
+ * abstraction layer. This pattern uses a central registry known as the "service 
+ * locator", which on request returns the information necessary to perform a certain task.
+ * <p>
+ * In this example we use the Service locator pattern to lookup JNDI-services
  * and cache them for subsequent requests.
