That's exactly right.After I have batched the clp file and before I run it,
I add a JessUser instance in the jess memory.Then I want to retreive a
field(java bean-specificUser) of this instance from the jess memory via the
defrule(as an argument of my userfunction).
public class JessUser { private boolean reportsLock; private User
specificUser;//<--this field I want to put as second argument public
JessUser() { this.reportsLock=false; } public boolean
isReportsLock(){ return this.specificUser.hasReportsLock(); }
public void setReportsLock(boolean rep){ this.reportsLock=rep; }
public User getSpecificUser(){ return this.specificUser; } public
void setSpecificUser(User usr){ this.specificUser=usr; } }
If I finally get this specificUser field,will it be the field of the exact
JessUser instance that I added in the engine before running it?
