jbpm jrule - Rule Compilation error

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
