[jboss-user] [JBoss jBPM] - jbpm jrules Rule Compilation error

[shoba]

Hi All, 
        Im working on jbpm jrule sample.  I'm getting this error while running jbpm application in jbpm-console. 
       Error completing task: An exception of type "org.jbpm.graph.def.DelegationException" was thrown. The message is: Rule Compilation error : [Rule name=Your First Rule, agendaGroup=MAIN, salience=0, no-loop=false] login/Rule_Your_First_Rule_0.java (2:23) : Only a type can be imported. com.sample.action.LoginBean resolves to a package login/Rule_Your_First_Rule_0.java (8:285) : l cannot be resolved login/Rule_Your_First_Rule_0.java (9:326) : l cannot be resolved com.sample.action.LoginBean 
          Please help me to get through this error. 

Here is my files:

loginrule.drl

package login 
import com.sample.action.LoginBean; 
#list any import classes here. 

#declare any global variables here 

rule "Your First Rule" 
        
        when 
        exists LoginBean 
                        LoginBean(username == "XXX") 
        then 
        System.out.println("first rule"); 
                
end
