I did see that I need to populate users, but I didn't at first seen any instructions on how to do so. Reading more carefully, I think I see how to do it now, i.e. by calling "addUser()". I'll give that a try a little later today. Another thing that may give me a problem is that I didn't know what the second argument should be to the TaskService() constructor below. The documentation shows only one argument, but it seems that there is no one argument constructor anymore. Any help with that? Really appreciate your help and time! -Chuck<br>

I see that problem before. It means that you need to populate some users first. Insert in the database an administrator user before running the process.<br><br></div><div class="gmail_quote"><div><div></div><div class="h5">

</div>I did manage to put some code together but I didn't feel from reading the<br>
documentation that I knew exactly what I was doing. I think it would be very<br>
helpful and many questions would be avoided if a worked out example could<br>
be provided with the drools distribution. Anyway, I really appreciate your<br>
help. The error I got is indicated below.<br>
