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,

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
