Hi,
I am new to JBoss rules. I have a .drl as given below:
rule "Rule1"
when
$Position1 : Position()
eval($Position1.getName() contains "POS-RPT_0_1")
then
util.setColor($Position1, "red");
end
Before firing the rules, I assert my object as
posIn = new Position(name,
id,
symbolCode,
lonDouble,
latDouble,
elevDouble,
reportDate,
this);
workingMemory.assertObject( posIn );
workingMemory.fireAllRules();
I get the following error.
org.drools.rule.InvalidRulePackage: Rule Compilation error The left-hand side of an
assignment must be a variable Syntax error on token "contains", invalid
AssignmentOperator
at org.drools.rule.Package.checkValidity(Unknown Source)
at org.drools.common.AbstractRuleBase.addPackage(Unknown Source)
What is wrong with my drl? I have a Utilities class that I have defined as global.
Thanks

Hi Smitha,
Rewrite the rule as follows :-
rule "Rule1"
when
$Position1 : Position ( name matches "POS-RPT_0_1" )
then
$Position.setColor("red");
end
Note : You had something called util, unless it is a global, it will not
work.

Hi Krishnan,
I need the functionality of being able to call methods of a global class in the
'then' piece of the drl. I had defined the drl file as:
package test.tools.rulesengine
import test.tools.rulesengine.Utilities;
global test.tools.rulesengine.Utilities util;
rule "Rule1".................
When I debug the 'when' piece, I see that the method to check the name is being
called, but tfter that, the global util's class method is not called. Any pointers
would be helpful.
Thanks,
Smitha

Hi Smitha,
They way I understand, in the then clause you would like to call a static
function from some class. So, then you can add that to the import and access
it directly. It does not have to be global. However, if for some reason you
do need to add it as a global,, let me know.
send that when part of the rule again.

Hi Krishnan,
I need the class itself to be global as I might have to access other functions of it as
I go along in the effort.
I cannot seem to be able to call the methods of this global class. I have also added a

hi smitha,
how do you know that setColor() is not getting called ?. Is it because you
have a break point inside this method.
Let me try this experiment and get back to you about whether it is working
for me or not. Also, which version of
drools are you using ?

ruleBase.addPackage( builder.getPackage() );
workingMemory = ruleBase.newWorkingMemory();
Utilities util = new Utilities();
workingMemory.setGlobal("util", util);
firstCall = false;
}else
ruleBase.addPackage( builder.getPackage() );
//workingMemory = ruleBase.newWorkingMemory();

Hi Smitha,
They way I understand, in the then clause you would like to call a static
function from some class. So, then you can add that to the import and access
it directly. It does not have to be global. However, if for some reason you
do need to add it as a global,, let me know.
send that when part of the rule again.

Krishnan,
I am using version 3.0.6.
And yes, I have a breakpoint inside this method.
Thanks

Hi Smitha,
Rewrite the rule as follows :-
rule "Rule1"
when
$Position1 : Position ( name matches "POS-RPT_0_1" )
then
$Position.setColor("red");
end
Note : You had something called util, unless it is a global, it will not work.

Before firing the rules, I assert my object as

What is wrong with my drl? I have a Utilities class that I have defined as global.
