Wookie uses HtmlCleaner to inject its own script tags into your Widget's start file when it is uploaded. This works fine in most cases; however if you use self-closing script tags things can go wrong. To avoid this always use regular HTML-style script tags e.g <script src="main.js"></script>
and not <scripr src="main.js"/>
. See Issue WOOKIE-42 for more information.
When I run Wookie in Tomcat I get a "java.security.AccessControlException: access denied (java.util.PropertyPermission user.dir read)"
This problem occurs when the security manager is enabled in Tomcat, but without the proper permission assigned for Wookie. There is a How-To that can help you define the security policy properly.
Wookie installs fine in Tomcat, but when I try to see it I get "org.hibernate.HibernateException: flush is not valid without active transaction"
