[rules-users] FW: Help me

[Anstis, Michael (M.)]

It looks like you are incorrectly using globals.
 
You need to insert a new fact into the working memory for
LoanApplicationBean (you currently add an instance as a global -
Final.main).
 
Your rule should also work on Facts and not globals (which should be
reserved for RHS function); for example:-

rule "go, go gadget validator"
    when
        $l : LoadApplicationBean( fullName == "" )
    then
        myGlobal.log("An inappropriate name");
end

All of which is in the documetation and examples.
 
I have not tried your code as I am at work...

Hi 
Thanks for your reply.
 
I have three rules in my rule file.I want that when i run my first java
program,out of those three rules only first two rules should be validated 
and when i run a other java program the only third rule should be validated.
For this i put my first two rules in one agenda group and i put the third
rule in another agenda group.
Now when i run my first java program then instead of validating only the
first two rules,the third rule is also validating and giving ma a exception
as:
