Passing objects from the application to the rulesets

Consider the following scenario:

• The application creates an instance a1 of a class A.
• The application passes a1 to the main ruleset.
• The main ruleset has rules that use a1 or passes a1 to the child ruleset.
• The child ruleset has rules that use a1.

The following figure shows the default relationship between the XOM class loaders of the rulesets:

By default, the following conditions apply:

• The parent class loader of the managed XOM of the main and child rulesets is the application class loader.
• The classes are taken in priority from the parent class loader.

The consequence is that the rules can use the instance a1 because the used class A is in the same class loader (which is the application loader).
