Hi
I am also a part of the user-list.
I am using Drools 4.0 with XML rule language.
I want to use the same .xml file with the two java programs.
Here are my programs
First java program:=
package com.wipro.rfq.report.bean;

import java.io.Reader;

*/

else
System.out.println(".");
}
else if(date.length()>10)
System.out.println("The entered date is not in proper format");
else
System.out.println("The entered date is not in proper format");
}
//load up the rulebase
final RuleBase ruleBase = readRule();
StatefulSession workingMemory = ruleBase.newStatefulSession();
RFQBean rfqbean=new RFQBean();
