Hi, After some configurations and ant, I put the jbpm.war under Tomcat5 webapps dir. And the login for "cookie monster" is ok, but something wrong after "create new web sale order". I remember after inputing the "item", "quantity", "address" and press "Save and Close Task", the task should be passed to "ernie", but what I got was the task still in cookie monster's task list. And , if I clicked the tasklist item, I will get the following error message in my IE. Does anyone have ever got this kind of error before? Thanks a lot!
