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

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 ?

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
snippet of the code.
Thanks
Smitha
Here is my drl
drl=
package test.tools.rulesengine
import test.tools.rulesengine.Utilities;
global test.tools.rulesengine.Utilities util;
rule "Rule1"
when
$Position1 : PosReport()
eval($Position1.getName() == "POS_0_1")
then
util.setColor($Position1, "red");
end
try {
builder.addPackageFromDrl (new StringReader( drl) );
if(firstCall){
ruleBase = RuleBaseFactory.newRuleBase();
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 ();
} catch (DroolsParserException e1) {
// TODO Auto-generated catch block
e1.printStackTrace();
} catch (IOException e1) {
// TODO Auto-generated catch block
e1.printStackTrace();
} catch (Exception e1) {
// TODO Auto-generated catch block
e1.printStackTrace();
}

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.

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,
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.

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
