[rules-users] accessing a drools variable

[rajivharris]

Hi , 

Thanks Bruno and Wolfgang for replying.

The getname() is a drools function which i want to invoke at runtime and set
the global variable.
Code:
global String prodCat;

rule "Your First Rule"
	
	when
		#conditions
		nameList : ArrayList()
		//prodCat : String()							
		eval (nameList.size() > 0)
	then 
		#actions		
		prodCat = getName(nameList);
		//modify (prodCat);
		System.out.println( "ArrayListSize:" +nameList.size());
		System.out.println( "ProductCategory:" +prodCat);
		
end

function String getName(List lstName)
{
	String name= "";
	String prodCat = "";
	
	for (Iterator iterator = lstName.iterator();iterator.hasNext();) {
		Map dsName= (HashMap)iterator.next();
		prodCat = dsName.get("name").toString();
		
		if(prodCat.equalsIgnoreCase("Rajiv"))
		{
			name= "Rajiv";
			break;
		}
		else if(prodCat.equalsIgnoreCase("Robin"))
		{
			name= "Robin";
		}		
	}
	return name;
}

JAVA:
String prodCat = "dummy";
StatefulKnowledgeSession ksession = kbase.newStatefulKnowledgeSession();
ksession.insert(lstName);
ksession.setGlobal("prodCat", prodCat);
ksession.fireAllRules();
System.out.println("Output:"+ksession.getGlobal("prodCat"));
