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&quot;)

then

util.setColor($Position1, "red&quot;);

end

 

Before firing the rules, I assert my object as

 

posIn = new Position(name,
   ; &nbsp;id,
 ; &nbsp; &nbsp;symbolCode,
 &nbsp;   ;lonDouble,
 &nbsp; &nbsp; latDouble,
&nbsp; &nbsp;  elevDouble,
&nbsp; &nbsp; &nbsp;reportDate,
   ; &nbsp;this);
&nbsp; &nbsp; workingMemory.assertObject ( posIn );
 &nbsp;  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
