You need to define a method that takes the Rete engine as an argument:
public void queryDatabase(..., Rete engine) {
...
engine.assert(...);
...
}
In your Jess script, you can the call
(call ?your-java-object queryDatabase ... (engine))
where ?your-java-object is the reference to an instance of your Java class.
(engine) is a predefined function that returns a reference to the Rete
engine.
Greetings, Thomas
