<table cellspacing="0" cellpadding="0" border="0" ><tr><td valign="top" style="font: inherit;"><DIV>Hi ,</DIV>
<DIV> i can suggest one more way to solve it. Dont create instance in when part.</DIV>
<DIV>Instead of better you convert that helper class method as static methods.</DIV>
<DIV>So that u can call that method directly . but before that u should import that helper class in drl file.</DIV>
<DIV> Or second way u can directly write a method in ur drl file itself.</DIV>
<DIV><BR>Example :</DIV>
<DIV> </DIV>
<DIV> <B><FONT color=#960000 size=2></DIV>
<DIV>import</B></FONT><FONT size=2> com.g2x.agility.leads.workflow.rulesengine.RuleUtilities;</DIV>
<DIV></FONT> </DIV>
<DIV> </DIV>
<DIV>rule"ConvertRule"</DIV>
<DIV> </DIV>
<DIV>when </DIV>
<DIV> eval ( RuleUtilities.getStringToInteger( age) > 40)</DIV>
<DIV>// getStringToInteger(String age) is static method</DIV>
<DIV> </DIV>
<DIV>then </DIV>
<DIV> System.out.print("XXXXName");</DIV>
<DIV> </DIV>
<DIV>end</DIV>
<DIV> </DIV>

That variable
here is rank, so, I create a helper class called 'Conversion' with just
one
function/method, which is supposed to convert the string argument passed to
it, to an integer and then I call that method in rule as inline eval.
What's
wrong here because this is not working and I don't want to change
'When'
part too much because it has 10 or so other variable with &&
connective,
which I've removed for clarity here. Any input would be appreciated much.
package harules;
import com.hibernate.Person;
import com.uhg.utils.Conversion;
rule "one"
salience 10
when
$con: Conversion();
pers: Person(age!= null , age >= 18 , eval($con.getInteger(rank) > 140))
then
System.out.println("Evaluated true");
end
//content of Conversion class
package com.utils;
public class Conversion {
public Integer getInteger(String s)
{
return Integer.parseInt(s);
}
}
