inline eval vs comparing booleans
by evertp
Hi
In the JBoss Rules 5.0 dev guide I read the statement:
When comparing inline eval with standard eval, we can see that they both
must
return true or false. However, inline eval must be a time-constant
expression.
It is evaluated only once and then it is cached by Drools
1. Can I assume that the caching lasts until the session is disposed of?
2. Is there a difference between the conditions Fact( eval(isValid) ) and
Fact( isValid == true ) or are they evaluated in the same way?
-Evert

Problem uploading project in eclipse
by Fnu Mahalakshmi
Hi,
I have created my rules and test scenarios as per the drools tutorial & guide.
But I am having trouble uploading that project into my Eclipse IDE.
I just selected upload from Guvnor Repository and I can then only select certain files.
Again the .brl files do not open in eclipse.
how I can test my sample dataset (contained in an excel file) in the drools guvnor itself without uploading the whole project in eclipse?
Or do I need to write all the rules from a scratch in eclipse again for it to work? Then whats the whole point of using the guvnor guided editor??
Please help me out. Am new to drools.
Thank you.

Importing data in drools applications..
by Mahalakshmi
hi,
I am new to drools and am really confused with the follwing:
1.
how I can go about adding a data set and modifying the data set based on my
rules.
Can I add a data set to my drools-guvnor itself and apply my rules to it and
check? Does the data set need to be in an excel file?
For example. I want to store 2 columns ( customer name & billingnumber)
2.
How can i import my drools project into eclipse and work with the data set?
Because when I tried doing that I could not see the rules I created in
eclipse. It just showed me the first import package statements.
Also I am unable to import the whole project at once.
Can somebody please guide me or give me some documentation I can refer to? I
am just going about in circles.
3.
How can I go about creating a front end for the application??
Any help highly appreciated :)
thank you.
