Can somebody translate this rule to the english ?

rule InsertMemberBlog
 no-loop
 activation-group "permissions"
when
 check: PermissionCheck(name == "memberBlog", action == "insert", granted == false)
 Principal(principalName : name)
 MemberBlog(member : member -> (member.getUsername().equals(principalName)))
then
 check.grant();
end;

I would like to create rule which test if the user own the request:

request.solver.loginName == principal

But I don't know how to do in drools. There is my not working rule:

rule solvRejectAssignment
when
 c: PermissionCheck(name == "request", action=="solvRejectAssignment")
 Role(name == "IMS_SOLVER")
 r:Request(state == RequestState.ASSIGNED)
 p:Principal()
 eval( p.equals(r.solver.loginName))
then
 System.out.println(p);
 c.grant();
end;
